tend to body) • Arteries (carry blood away from heart) - blood vessels that transport O-rich blood away from heart to body  tissues - branch into smaller vessels called arterioles, that deliver blood to  joining microscopic vessels called capillaries • Capillaries • Veins (carry blood back to heart and lungs) - Receive blood from capillaries after the exchange of O and CO2 takes place, and transport waste-rich blood back to lungs and heart 4 chambers connected by 4 heart valves:  • atria or upper chamber- collect blood returning to the heart • ventricle or lower chamber- pump blood out of the heart to the lungs and the rest  of the body  - thumping sound from heart is made from the 2 pairs of valves closing as blood  moves through the organ - these valves are composed of thin fibrous cusps covered by smooth membrane  called the endocardium and reinforced by connective tissue Layers and membranes of the heart • Endocardium, innermost layer that lines the heart and heart valves • Myocardium, muscular layer • Pericardium, outermost layer  - Membrane that surrounds the heart as the pericardial sac and secretes  pericardial fluid. - Heart is located within the pericardial sac. - Pericardial cavity contains serous fluid, which reduces friction between the  pericardial membranes as the heart moves (contracts and relaxes) within them. Function • Circulates blood and delivers O2 and nutrients to cells - Right side for circulating blood to lungs for oxygenation (pulmonary  circulation) - Left side for circulating blood to all body systems (systemic circulation) • Disposes of waste products • Aids lymphatic system in circulating substances Deep Vein Thrombosis (DVT) Signs and Symptoms  • Formation of a thrombus, usually in calf or thigh muscle• Part or complete block of blood flow • May cause pain, but often asymptomatic Treatment • Anticoagulants  • Prevent future thrombi formation • Thrombolytics  • Dissolve blood clots Coronary Artery Disease (CAD) Signs and Symptoms • Angina  • Shortness of breath (SOB) • Accumulation of plaque in arterial walls causing them to harden. • Complete blockage of arterial wall caused by blood clot formation or  ruptured plaque. • Pieces of plaque break free, travel to the brain, and block blood vessels that  supply blood to the brain. • Risk factors • Smoking • Hypertension, stress • Physical inactivity • Family history • Diabetes • Obesity • High cholesterol Treatment • Lifestyle changes: quit smoking, low-fat diet, regular exercise, weight reduction,  and stress reduction. • Pharmacological treatment to control angina, hypertension, triglyceride levels,  and blood clots. • Surgical intervention includes percutaneous transluminal coronary angioplasty  (PCTA).Aneurysm Signs and Symptoms • Local dilation of an artery or chamber of the heart due to weakening of its walls. • May cause thrombus formation, hemorrhage from rupture, or ischemia. • Fusiform – dilation of entire circumference • Saccular – shaped like a sac, bulging on only one side • Dissecting – inner layer tear causes a cavity to form that fills with blood with each  heartbeat) • Three common types: abdominal, thoracic, and peripheral artery aneurysms. • May be asymptomatic, but if the person is slender, a pulsating middle and upper  abdominal mass may be detected on routine physical examination. • Symptoms may include mild to severe weakness, sweating, tachycardia, and  hypotension. Treatment • Depends on the size, location, and the likelihood of its rupturing, as well as the  general physical status of the individual. • Most are treated surgically. Varicose Veins (veins fail to circulate blood properly, pools of blood occur) Signs and Symptoms  • Defective or incompetent valves in veins prevent blood from flowing freely  toward the heart.  • Buildup of pressure in superficial veins causes varicosities.  • Could be due to inherited defect or to venous diseases. • May occur from conditions, such as pregnancy or jobs requiring prolonged  standing or heavy lifting. • Person may be asymptomatic even though the varicose vein condition is  severe. • Swollen, tortuous, and knotted veins, usually occur in the lower legs. • As the condition progresses, veins thicken and feel hard to the touch. • Develop gradually, with a feeling of fatigue in the legs followed by a dull  ache.Treatment • Compression stockings. • Sclerotherapy, injection into varicose veins with a solution that scars and closes  the veins. • Laser—laser treatments use strong bursts of light into the vein to close off  varicose veins to make the vein slowly fade and disappear.  Diagnostic Procedures Cardiac catheterization • Catheter is guided into the heart via a vein or artery.  Cardiac enzymes • Test to measure levels of enzymes released into the blood during an MI.   Holter monitor • Records ECG readings, usually 24 hours, on a portable tape recorder to document  arrhythmias and link them to activities or to symptoms, such as chest pain. Stress test • Exercise tolerance test to determine the heart’s response to physical exertion  (stress). • ECG is recorded under controlled exercise stress conditions using a treadmill. • Nuclear stress test uses a radioisotope to evaluate coronary blood flow. Doppler Ultrasonography (US) • US used to assess blood flow through blood vessels and the heart. • Handheld US transducer emits sound waves as it is placed on the carotid artery  to produce images of blood flow. • Carotid Doppler creates detailed images of the inside of the carotid arteries in  the neck to check blood flow caused by plaque or blood clots.  Troponin I • Blood test that measures levels of proteins released into the blood when  myocardial cells die (damaged heart muscle). EKG, ECG • Recording of electrical activity of the heart • with each heartbeat, electrical signals travel from the top to bottom of the heart,  causing contractions and pumping of blood  • doctor can determine how long it is taking an electrical wave to pass through your  heart. This shows if the electrical activity is normal, fast, slow or irregular  Medical and Surgical Procedures Automatic implantable cardioverter-defibrillator (AICD) • Device implanted in a patient who is at high risk for developing a serious  arrhythmiaAngioplasty • Any endovascular procedure that reopens narrowed blood vessels. • Restores blood flow, usually using balloon dilation. Coronary artery  bypass graft (CABG) • Vein taken from leg or other part of the body is grafted onto the heart to  circumvent an obstruction in a coronary artery.  Valvuloplasty • Surgical repair or replacement of a valve. If a balloon is used to open a defective valve, it is called balloon valvuloplasty. Pharmacology Beta blockers • Decrease heart rate and dilate arteries by blocking beta receptors. • Treat angina pectoris and hypertension. Nitrates • Treat angina pectoris. • Dilate veins, which decreases the amount of work the heart must do. • Dilate arteries to decrease blood pressure.  Statins • Lower cholesterol levels in the blood. • Reduce cholesterol production in the liver. • Block the enzyme that produces cholesterol. Thrombolytics • Lyse (break apart) blood clots. • Used in acute management of myocardial infarction (MI) or heart attack. - Sudden blood clot needs immediate treatment to restore blood flow in the  artey. If not, could cause MI • Used to treat ischemic stroke. Lymphatic system structure • Lymph nodes • Lymph vessels and lymph fluid • Lymphatic organs • Tonsils, thymus, and spleen • Network of vessels that depends on pumping action of the heart to circulate its  substances throughout the body. Main functions • Drain excess interstitial fluid from tissues and return it to the circulating blood. • Absorb and transport digested fats to venous circulation. • Produce lymphocytes and other immune cells that protect the body from injury  and disease, such as bacteria, viruses, and cancerous cells. Lymph nodes  • Small masses of lymph tissue, also called lymph gland. • Tend to occur in clusters or chains. • Major groups of nodes are located in the cervical (neck), axillary (armpit), and  inguinal (groin) regions of the body. • Lymph is filtered through these nodes as it passes through lymph vessels.• When bacteria accumulate in lymph nodes (as in a bacterial infection),  nodes become swollen and tender. • Lymph fluid is rich in leukocytes, lymphocytes are part of these cells • Phagocyte is another type of leukocyte, it helps fight off infection by  surrrounding engulfing and digesting micororgansism and cellular debree Spleen (removes microbes from body and destroys old or damaged red blood cells) • Organ similar in structure and function to a lymph node, but is much larger. • Filters lymph. • Manufactures lymphocytes and monocytes. • Destroys old erythrocytes. • Stores new erythrocytes for release into the bloodstream as needed. • Not essential to life. • If spleen is removed, other organs take over its function. Thymus • Secretes a hormone called thymosin. • Thymosin stimulates red bone marrow to produce T lymphocytes (T  cells). • T cells provide a defense against disease. • Attack and destroy foreign or abnormal cells.  Tonsils • Filter lymph. Destroy bacteria entering the mouth and throat Lymphedema Signs and Symptoms • Abnormal accumulation of lymph, usually in the extremities. • Symptoms eventually include pallor, weakness, lymph node enlargement, fatigue,  fever, and weight loss. • Affected limb, in part or whole, is typically swollen and hypertrophied with  thickened and fibrotic skin. • As disease progresses, tachycardia, palpitations, and an increased incidence of  infections are common. Treatment • Control pain • Lessen swelling by moving lymph out of the affected limb. • Gentle exercise, massage, bandaging, compression garments. • Surgery to correct lymphatic obstruction and promote drainage may be necessary  in some instances. Systemic Lupus Erythematosus (SLE) Signs and symptoms  • Chronic inflammatory autoimmune disease.• Characterized by unusual antibodies in the blood that target tissues of the body.  • Butterfly-shaped rash or erythema on the face. • Inflames and damages connective tissue anywhere in the body. • Most commonly produces inflammation of skin, joints, nervous system, kidneys,  lungs, and other organs. • Degree to which these tissues are involved varies from patient to patient. • Similar rashes may appear on other exposed areas of the body • Exposure to sun can aggravate the rash. • Fever, fatigue, joint pain, and malaise may begin acutely or develop slowly over  a period of years. • Occurs most often in young women in their 20s or 40s.  Treatment • Anti-inflammatory drugs, including aspirin. • Corticosteroids for severe cases. • Sometimes antimalarials are added. • Immunosuppressive agents when life-threatening or severe crippling disease is  present.  Kaposi Sarcoma Signs and Symptoms  • Lymphatic malignancy. • Composed of multiple red or purple macules, papules, or nodules  on skin and mucous membranes. • First appear on lower extremities but spread to upper body, face,  mucous membranes of throat, and internal organs. • Closely associated with HIV infection and is considered an “AIDS-defining  condition.” Treatment  • Depends on stage of HIV infection and degree of metastasis. • Common treatment modalities include radiation therapy, chemotherapy, surgery,  and immunotherapy. • Palliative treatment and good oral hygiene are essential.  Diagnostic Procedures Bone marrow aspiration • Withdrawn for microscopic evaluation (usually from pelvic bone) • Used for stem cell transplant or chromosomal analysis. • Used to determine if a known cancer, such as Hodgkin and non-Hodgkin  lymphoma, has spread to the bone marrow. • Part of staging process to determine if cancer has spread and how much  has spread. ELISA • Blood test that detects antibodies in blood  • Screening for an antibody to the AIDS virusTissue typing • Used to determine histocompatibility of tissues. • Used in grafts and transplants with recipient’s tissues and cells. • Also known as histocompatibility testing. Medical and Surgical Procedures Bone marrow transplant • Infusion of healthy bone marrow stem cells after diseased bone marrow is  destroyed by chemotherapy or radiation. • Used to treat aplastic anemia, leukemia, and certain cancers. Lymphangiectomy • Excision of one or more lymphatic vessels, usually due to cancer. Pharmacology Antivirals • Inhibit development of specific viruses. • Used to treat HIV infections and AIDS.

Ch6 Digestive system Structure Oral cavity • Teeth • Salivary glands Pharynx Esophagus Stomach • Pyloric sphincter Small intestine • Duodenum, jejunum, ileum Large intestine • Cecum is connected to small intestine by ileocecal valve. - Appendix hangs from the cecum. • Ascending colon, transverse colon, and descending colon - Sigmoid colon - Rectum - Anus Accessory organs • Liver • Gallbladder • Pancreas… Ch7 Urinary system Structure and Function Kidneys • Primary functional organs of the urinary system. • Filter urea and other waste products from the blood. • Shaped like a kidney bean. • Maintain proper balance of water and electrolytes in the body. - Maintain balance by removing waste products of metabolism from  blood through urine formation. • Each kidney is comprised of an outer layer, the renal cortex; and an inner  layer, the renal medulla. • Blood enters the kidney through the renal artery. Renal artery  • Branches into smaller and smaller arteries, eventually leading to  microscopic filtering units called nephrons. Nephron • Microscopic functional unit of the kidney • Forms urine in renal corpuscles and tubules by process of filtration,  reabsorption, and secretion • Renal corpuscle is the site of blood filtration in the nephron and consists  of the glomerulus and Bowman capsule. • Glomerulus, a cluster of capillaries. • Waste-containing fluids (filtrate) are absorbed into  Bowman capsule. • Filtrate flows from the capsule into the renal tubule. • Renal tubule • Urine formation is completed in the tubules. • Urine flows from renal tubule to the renal pelvis. • Each renal pelvis (one from each kidney) narrows to form a  ureter. Ureters• Approximately 12-inch-long tube that connects renal pelvis of the kidney  to the bladder. • When muscles of ureters contract, urine is pushed from the kidneys into  the urinary bladder. Bladder • Hollow, muscular sac in pelvic cavity. • Serves as a temporary reservoir for urine. • Expands as urine collects; contracts when urine is excreted. Urethra • Tube extending from the bladder to the external opening, urinary meatus. • Serves as a passageway for excretion of urine from the bladder. • Process of excreting urine is called voiding or micturition.  End-Stage Renal Disease (ESRD) Signs and Symptoms • Irreversible stage with gradual, progressive deterioration of kidney function. • Kidneys lose ability to excrete nitrogenous end products of metabolism. • Progressive weakness, anorexia, diarrhea, pruritus, and polyuria. • Severity of signs and symptoms varies depending on extent of renal damage and  remaining function. • Usually result of chronic renal failure (CRF), the gradual, progressive  deterioration of kidney function to the point that the kidneys cannot sustain their  necessary day-to-day activity.Treatment • Dietary restriction of protein, sodium, and potassium intake • Antiemetics for nausea • Control of hypertension Renal Calculi Signs and Symptoms • Concentration of mineral salts in the renal pelvis, in the calices of the kidney, or  in the urinary tract. • Renal calculi patients may remain asymptomatic for long periods. • If stone or calculus fragment lodges in a ureter, there may be intense pain and  urinary urgency. • If calculi are in the renal pelvis and calices, pain is duller and more constant. • Back pain and severe abdominal pain may occur. • Other symptoms include nausea, vomiting, chills and fever, hematuria, and  abdominal distention. Treatment • Remove stones and prevent new formations. • Enhance elimination of stones and increase fluid intake. • Small stones pass spontaneously without treatment. Large stones may require  surgical intervention. • Antibiotics may be prescribed if calculus build-up is due to bacterial infection. • Strong analgesics are prescribed for relief of intense pain. • Ultrasound is used to locate and monitor calculi as they are being destroyed. Hydronephrosis Signs and Symptoms • Distention of renal pelvis and calices due to pressure from accumulating urine. • Pressure impairs, and may eventually interrupt, kidney function.• If obstruction is above bladder opening, only one kidney may be affected and  person may be asymptomatic for a prolonged period. • If both kidneys are affected, symptoms may include intense pain, nausea,  vomiting, oliguria or anuria, and hematuria. Treatment • Remove obstruction, prevent complications, and treat underlying disorders. • Catheterization for immediate relief of urinary pressure. • Analgesics may be prescribed. • Antibiotics are required if infection occurs. • Surgery if needed to dilate a ureteral stricture. Diagnostic Procedures Cystoscopy • Examination of urinary bladder  • Obtain biopsies or tumors, remove polyps. • Obtain evidence of a pathology. Bladder ultrasonography  • High-frequency sound waves produce images of the bladder. • Determines bladder volume. • Identifies incomplete bladder emptying. Blood urea nitrogen (BUN) • Laboratory test that determines amount of nitrogen in blood that comes  from urea. • Used as an indicator of kidney function. Urinalysis • Urine screening test. • Includes physical observation, chemical tests, and microscopic evaluation. Voiding cystourethrography (VCUG)• X-ray of the bladder and urethra. • Performed before, during, and after voiding using a contrast medium to enhance  imaging.  Medical and Surgical Procedures Catheterization • Insertion of a catheter into a body cavity or organ  • Used to instill a substance or remove fluid • Most commonly performed through urethra into the bladder to withdraw  urine. Hemodialysis • Patient’s blood is diverted into a dialysis machine for filtering. Peritoneal dialysis • Dialysis in which patient’s own peritoneum is used as the dialyzing  membrane. Contaminated fluid drains out and is replaced with fresh  solution. • Illustration: (A) Introducing dialysis fluid into peritoneal cavity. (B)  Draining dialysate with waste products from peritoneal cavity. Extracorporeal shock-wave lithotripsy (ESWL) • Powerful sound-wave vibrations break up calculi in urinary tract or  gallbladder. • Administration of an oral dissolution drug removes the stones and their  fragments during urination.Renal transplantation • Diseased kidneys replaced by transplanted kidney. Pharmacology Antibiotics • Treat bacterial infection of urinary tract. • Act on the bacterial membrane or one of its metabolic processes. • Type of antibiotic prescribed depends on the infecting organism and the  type and extent of infection. Antispasmodics • Suppress spasms in ureter, bladder, and urethra by relaxing smooth  muscles lining their walls. • Allow normal emptying of the bladder.  Diuretics • Promote and increase excretion of urine.

Clinical Exercise Bob and Mary have been trying to conceive for over 3 years. The physician prescribes  Bob a hormonal preparation used to increase sperm count that is known as (estrogen,  gonadotropin, testosterone). George uses a method of birth control that destroys sperm by creating a highly acidic  environment in the uterus. The name of this agent that kills sperm is called a spermicide. Joseph is diagnosed with BPH and is scheduled for a surgical procedure that uses a  resectoscope to chip away at the prostate. The abbreviation for this surgical procedure is  TURP. Michael is scheduled for TURP. He asks the physician to explain how the procedure is  performed. The physician explains that an instrument called a resectoscope is inserted  through the urethra, and a small loop “chips away” some of the obstructing tissue.  James comes to the urologist’s office for consultation. After the birth of their third child,  James and his wife decide that he should undergo a method of male contraception in  which the vas deferens is excised. This surgical procedure is called a vasectomy. Kyle sustains a severe laceration of the left testicle in a construction accident. The  urologist advises a surgical repair of the testicle, commonly referred to as orchidoplasty. Mr. L has a 3-year history of prostate cancer and wants to avoid surgery. The physician  recommends hormonal therapies to limit prostatic cell growth. A female hormone is  prescribed for this treatment and is known as a/an (antidiuretic, estrogen, progesterone).  Mr. J arrives at the emergency department and has been unable to urinate for 16 hours.  The physician notes the patient’s bladder is distended. Based on this finding the physician  suspects an enlarged prostate known by the medical term prostatomegaly. A 50-year-old male presents for his annual physical. He is concerned about his risk of  prostate cancer and asks the physician to explain the symptoms of this disease. The physician explains that early stages are often asymptomatic. When symptoms occur,  they include dysuria, difficulty in voiding, urinary frequency, and urinary retention. A 45-year-old male patient complains of frequent urination at night. The physician  documents this finding as nocturia.Tyler is diagnosed with a benign tumor of the prostate. The doctor explains that benign  tumors are not cancerous and are not life threatening. However, severe cases may include  an infection of the renal pelvis and kidney known as pyelonephritis. Results of Fred’s pyelography indicate urine retention and obstruction of urinary flow  due to prostate enlargement. The medical term when urine accumulates in the renal pelvis  is known as (hydrocele, hydromyoma, hydronephrosis). Barney is diagnosed with BPH. He asks the nurse to explain BPH.  She explains that BPH refers to a benign prostatic hyperplasia. It is a nonmalignant  enlargement of the prostate gland caused by excessive growth of prostatic tissue.  Tom presents complaining of fever, chills, urinary frequency, and urgency. On  examination, the prostate is soft, swollen, and tender. The physician suspects an  inflammation of the prostate gland and bladder and charts a diagnosis of prostatocystitis. Lauren, a 22-year-old, is sexually active with her husband but wants to wait a couple of  years before having children. The nurse practitioner explains the most effective option to  prevent conception is to use an agent known as an (antifungal, estrogen, OCP).  Mrs. C is postsurgical total hysterectomy plus bilateral salpingo-oophorectomy. The  gynecologist prescribes HRT now that the ovaries are removed and unable to produce  estrogen and progesterone. The HRT abbreviation means hormone replacement therapy.  The patient presents with a vaginal yeast infection. The physician prescribes a  suppository (antifungal, estrogen, HRT). Mrs. A is menopausal and has symptoms of vaginal dryness and hot flashes. The  physician writes her a prescription for an agent known as an (antifungal, estrogen, OCP). Ms. Y presents with heavy bleeding over the last 6 months and is scheduled to have a a  scraping of uterine endometrium with a curet after dilation of the cervix. The  abbreviation for this procedure is D&C. Susan is considering reconstructive breast surgery following her mastectomy and is  considering the TRAM flap procedure. What is the meaning of the abbreviation TRAM?  transverse rectus abdominis muscle The patient is scheduled for a transabdominal puncture of the amniotic sac under  ultrasound guidance to remove amniotic fluid to find out if her baby has any genetic  abnormalities. The physician documents this procedure as an amniocentesis. The patient is scheduled for removal of her uterus with the cervix, ovaries, and fallopian  tubes intact. The physician charts this surgical procedure as a subtotal hysterectomy.Mary presents to the obstetric clinic in her early third trimester with symptoms of  premature labor. The physician recommends a procedure to suture the cervix to prevent  premature labor and decrease the chance of spontaneous abortion. This procedure is  called cerclage. Patient is scheduled for removal of her uterus and both fallopian tubes. The physician  charts this surgical procedure as a total hysterectomy plus bilateral A: salpingo oophorectomy. A 15-year-old arrives at the clinic for birth control counseling. After weighing her  options, she decides that birth control pills are her best option because they are highly  reliable and easy to use. The abbreviation for the oral contraceptives is OCPs. June comes into the clinic complaining of pain during sexual intercourse. The medical  assistant documents this complaint as (dysmenorrhea, dyspareunia, dysuria).  Joan, a 22-year-old, presents to the office with severe pain with menstruation. Her  complaint is documented as dysmenorrhea. During laparoscopy, ectopic deposits of endometrial tissue are noted within the pelvis.  The doctor charts this condition of endometrial tissue outside of the uterus as  (endometritis, histometrial, endometriosis). Mary is scheduled for a modified radical mastectomy to treat her breast cancer. This  surgical procedure involves removal of the entire breast and excision of the underarm  lymph nodes. The medical term for removal of the lymph node is lymphadenectomy. Sasha is diagnosed with breast cancer and asks the doctor the types of treatments  prescribed for breast cancer besides surgery.  The physician explains that radiation, chemotherapy, and hormonal therapy are the  treatments other than surgery. Mrs. S had a mastectomy because of breast cancer. The doctor explains the postsurgical  adjuvant chemotherapy he is recommending. Can you explain the purpose of adjuvant  chemotherapy? Chemotherapy is used to enhance or extend the effects of surgery and to  eliminate any possible metastasis. Lisa detects a lump in her breast while performing breast self- examination. After  mammography shows a small tumor, an excision of the breast tumor is performed. This is  known as a lumpectomy. The nurse explains that a common cause of scarring or blockage of the fallopian tubes is  due to infections such as PID. This abbreviation is defined as pelvic inflammatory  disease.Jean is diagnosed with ectopic pregnancy in the fallopian tube. The obstetrician informs  her of the risks involved with this type of pregnancy. What are some of these risks?  The fallopian tube may rupture, which is life threatening. It may also cause severe  abdominal pain and intra-abdominal bleeding. Ellen presents to the emergency department complaining of abdominal pain. Computed  tomography scan of the abdomen reveals an ovum has implanted in her fallopian tube. A  pregnancy for an implanted ovum outside of the uterine cavity is known as an ectopic  pregnancy. The doctor diagnoses Heather with ectopic pregnancy. She asks her to explain what  causes this condition. The doctor explains that it is caused by a blockage or scarring of  the tubes which prevents the fertilized egg from being transported to the uterus. Mrs. T is diagnosed with a urinary tract infection. To treat the bacterial infection, the  physician prescribes an (analgesic, antibiotic, antispasmodic).  To relieve the patient’s nephralgia, the physician prescribes an (analgesic, antibiotic,  antispasmodic). A chest x-ray reveals an accumulation of fluid in the lungs. The doctor prescribes a drug  to stimulate production and flow of urine. The drug is a/an (antispasmodic, antidiuretic,  diuretic). Mr. Q was catheterized for surgery and now experiences spasms in the urethra and  bladder. To decrease the spasms and allow normal emptying of the bladder, the doctor  prescribes a/an (antispasmodic, antidiuretic, diuretic). The patient is in ESRD and requires his blood to be diverted into a machine and filtered,  twice a week, since his kidneys are no longer functioning. The procedure to have blood  filtered outside of the body by a dialysis machine is called hemodialysis. Mrs. M is diagnosed with kidney failure and she must receive peritoneal dialysis. She  asks the doctor what the difference is between peritoneal dialysis and hemodialysis.  Peritoneal dialysis uses the patient’s own peritoneum as the dialyzing membrane.  Hemodialysis uses a dialysis machine as the dialyzing membrane. Mr. M is diagnosed with multiple renal calculi. The doctor explains that the treatment of  choice is to use powerful sound-wave vibrations to break up the kidney stones. The  abbreviation for this procedure is ESWL. Mrs. A has a history of bladder carcinoma and presents for an endoscopy of the urinary  bladder. Any growths that are present will be removed and biopsied. This visual  examination of the bladder is a medical procedure called cystoscopy.Mrs. C is unable to urinate after surgery so a catheter is inserted through the urethra and  into her bladder to remove urine. This therapeutic procedures is known as catheterization. Mr. G is diagnosed with nephrolithiasis. The medical assistant explains that the kidney  stones need to be crushed into smaller pieces so they can be expelled in the urine.  Crushing of stones is a surgical procedure called lithotripsy. Radiographic studies of a patient’s kidneys reveal enlargement of the right kidney. The  radiologist documents this as nephromegaly. Mr. J undergoes surgical repair of the renal pelvis. Before obtaining informed consent,  the physician charts this surgical procedure as pyeloplasty. Mary presents at the clinic concerned because she only urinated once in the past 24 hours.  The medical term for this symptom is (anuria, dysuria, enuria). Mrs. M presents because her urine is red. The nurse documents this finding as hematuria. Upon diagnosis of ureterolithiasis, the doctor informs Mrs. S that she may experience  pain and have difficulty urinating. The medical term for painful or difficult urination is  dysuria. Mrs. H presents with complaints of pain, nausea, and hematuria. Based on her past  history of nephrolithiasis, the physician orders an imaging technique that utilizes high frequency sound waves to detect presence of calculi. This imaging procedure is called an  ultrasound. Mrs. J develops kidney stones even though various treatments were undertaken. The  patient must undergo a surgical procedure in which an incision is made to remove the  stones. This procedure is called lithotomy. A patient diagnosed with renal calculi presents to the office complaining of pain in the  kidney area. The medical term for this symptom is nephralgia or nephrodynia. Mrs. M is diagnosed with ESRD and is given dietary restrictions of food with protein,  potassium, and sodium or salt. A 38-year-old female is admitted with pyonephrosis. A key finding of the inflammatory  condition is the accumulation of pus in the kidneys. Mr. J requires renal transplantation because his kidneys no longer filter toxic wastes from  the blood? His disease is charted as ESRD, or end-stage renal disease.  Mrs. M is diagnosed with ESRD. Her symptoms include progressive weakness, diarrhea,  pruritus, polyuria, and loss of appetite. The medical assistant charts her loss of appetite as  anorexia. Mr. X is a postsurgical patient who complains of soreness in his right calf muscle. The  doctor assesses the right calf and finds it to be warm and red. What is the likely  diagnosis for Mr. X? DVT  The physician prescribes medication for Mr. X to dissolve his DVT. This type of  medication is called a thrombolytic. To prevent the patient from contracting a viral infection, the physician prescribed a/an  (corticosteroid, antiviral, immunosuppressant). Treatment of HIV infection and AIDS includes the use of (corticosteroids, antivirals,  immunosuppressants). To prevent rejection of Mary’s recently transplanted kidney, the physician prescribed  a/an (anticoagulant, immunosuppressant, thrombolytic). The American Medical Association (AMA) recommends vaccination of immune  globulins to induce immunity to certain infectious diseases. These vaccinations are  known as (anticoagulants, immunizations, immunosuppressants) An MRI reveals a lymphangioma. The physician explains that the tumor needs to be  excised. The term for excision of a lymph vessel is lymphangiectomy. Bill is diagnosed with leukemia. His physician recommends irradiation and  chemotherapy of the bone marrow followed by replacement of healthy blood cells. This  type of treatment is called (bone marrow aspiration, bone marrow biopsy, bone marrow  transplant). Jason undergoes magnetic resonance imaging (MRI) that reveals a tumor composed of  lymph vessels. This tumor is known as a lymphangioma. The patient is diagnosed with KS and asks the physician what type of medical treatment  is needed. The physician explains that treatment depends on the stage of HIV infection  and degree of metastasis. Some common treatment modalities include radiation therapy,  chemotherapy, surgery, and immunotherapy. John is diagnosed with Kaposi sarcoma (KS) and asks the medical assistant to explain  this disease. He explains it’s a malignancy of connective tissues, especially the tissue  found under the skin, mucous membranes, and in the lining of lymph vessels; usually  associated with HIV. Mr. Z with a history of HIV+ presents with purplish brown papules on both arms and  legs. The doctor suspects he has a cancer that is associated with AIDs. This type of  cancer is known as Kaposi sarcoma.Ms. Z suffers from SLE and states that aspirin is no longer working. The physician  prescribes other drugs to reduce inflammation that are called (analgesics, antithyroids,  corticosteroids). When SLE becomes life threatening the physician may order drugs to suppress the  immune system. These drugs are called (antithyroids, immunosuppressives, NSAIDs).  Ms. Z is diagnosed with systemic lupus erythematosus. The medical assistant charts the  abbreviation as SLE. The patient asks the physician about the typical symptoms of systemic lupus  erythematosus. The physician explains that more noticeable symptoms include fever,  fatigue, joint pain, and malaise. These symptoms develop over a period of time and may  appear suddenly. Symptoms may include rashes on exposed areas of the body, including  a “butterfly” rash on the face. Mr. G presents with swelling and excessive accumulation of lymph in his right leg. The  physician diagnoses this condition as (lymphoma, lymphomegaly, lymphedema). Dr. J detects lymphedema as he examines Mrs. L after her surgery. Dr. J explains that this  condition is due to a blockage in the lymphatic system which prevents drainage of lymph  fluid. It is also a common complication following removal of the breast, a surgical  procedure called mastectomy.  The patient has a history of lymphedema and presents with a swollen, red area of skin  that feels hot and tender in the right arm. The physician diagnoses this as skin infection,  which is called (cellulitis, hepatitis, lymphadenitis). Mary is diagnosed with lymphedema in her right arm and asks the nurse what can be  done to lessen the swelling. The nurse explains that swelling can be decreased by moving  lymph out of the right arm through gentle exercise, massage, bandaging, and compression  garments. Mrs. S. presents with angina pectoris and is prescribed a drug to relieve her pain.  It is called a (beta blocker, nitrate, statin).  To lower blood pressure, the doctor prescribes a (beta blocker, nitrate, statin).  Mrs. T is diagnosed with deep vein thrombosis in her lower leg. She is prescribed a drug  that dissolves a blood clot. It is known as a (beta blocker, nitrate, thrombolytic). Mr. B is diagnosed with hypercholesterolemia and advised to follow a low-fat diet. He is  prescribed a drug that reduces cholesterol levels and is known as a (beta blocker, nitrate,  statin).Lily is scheduled to have surgery on her mitral valve. The surgeon charts surgical repair  of the valve as valvuloplasty. Ms. B is diagnosed with ventricular fibrillation. The treatment of choice is to implant a  battery-powered device that monitors and automatically corrects tachycardia by sending  electrical impulses to the heart. The abbreviation for this defibrillator is AICD. Mr. T is scheduled for surgery to bypass one or more of his blocked coronary arteries in  order to restore blood flow. This surgery is charted as coronary artery bypass surgery. Mr. D is diagnosed with CAD. Treatment for his condition involves an endovascular  procedure that will reopen the narrowed blood vessels and restore blood flow. The  blocked vessel is usually opened by balloon dilation. This surgical procedure is known as  a/an (anastomosis, angioplasty, endartotomy). Mrs. T presents with chest pain that radiates to her left arm. She is pale and is perspiring  profusely. An ECG reveals necrosed heart tissue. The physician diagnoses Mrs. T with  (fibrillations, MI, palpitations). The nurse explains to Mr. X, who is diagnosed with CAD, that lifestyle changes could  reduce risk of further heart complications. Lifestyle changes include exercise regularly,  lose weight, quit smoking, reduce stress, and maintain a diet low in saturated fat. A 50-year-old male presents to the clinic complaining of pressure and pain in his chest.  After a brief exam, the doctor concludes that his symptoms are due to lack of oxygen to  the heart. This condition is called angina pectoris. Mr. S complains of chest pain, nausea, and SOB. A diagnostic test to record electrical  activity of his heart is ordered. This diagnostic test is called a/an electrocardiogram  (ECG) or electrocardiography (ECG). Walter is scheduled for balloon angioplasty to crush fatty deposits in the coronary vessel  and improve blood flow. He is told this is known as PTCA, the abbreviation for  percutaneous transluminal coronary angioplasty. An aneurysm may cause weakness, sweating, tachycardia, and low blood pressure, also  known as (hypotension, hypertension, hypothymia). During a physical examination, the doctor palpates and feels an abnormal dilation of a  blood vessel. This may be diagnosed as a/an (aneurysm, carcinoma, tumor).  Mr. J is advised that he needs to have his aneurysm removed. The surgical procedure to   excise an aneurysm is known as a/an aneurysmectomy. During surgery, the doctor discovers a spindle-shaped aneurysm in the patient’s artery.  This type of aneurysm is known as a/an (dissecting, fusiform, saccular) aneurysm.After four pregnancies, Mrs. X noticed twisted enlargements of the veins in her lower  legs. She complains of pain that is not relieved even when she elevates her legs or uses  compression stockings. Dr. D recommends a chemical injection into the varicosities to  destroy and close the veins. This procedure is known as (sclerotherapy, ligation and  stripping, laser ablation). An 87-year-old nursing home resident has a history of vascular problems and dependent  edema. Recently, he developed skin ulcers on his lower legs. His daughter asked what  caused the ulcers. The nurse explains that skin ulcers are a complication associated with  (varicose veins, advanced age, skin allergies).
