KNR 180 Exam #1 Study Guide Chapter 1  When a person’s heart stops and they are without oxygen: 4 minutes= death  Number of people that experience a nonfatal injury that requires medical care: 1 in 4  Purpose of first aid: to TREAT what you see (yourself and others) – NOT to diagnose  Who must you gain consent to treat: victim’s consent or parent or legal guardian of victim (if victim is a child; consent is implied if parent or guardian is not present)  Types of consent: expressed or implied  What to do if a victim refuses treatment? o Explain:  his or her condition  what you intend to do  why it is necessary. o Call 9-1-1. o Try again to persuade the victim to accept care o Stay with the person  A police officer is the only person with the authority to restrain and transport a person against that person’s will.  Breach of duty: o An act of omission is the failure to do what a reasonably prudent person with the same or similar training would do in the same or similar circumstances. Not doing something you should have that causes harm. o An act of commission is doing something that a reasonably prudent person would not do under the same or similar circumstances. Doing something you shouldn’t have that causes harm.  Purpose of Good Samaritan laws (i.e. they protect first aiders who do what?) o Good Samaritan laws protect the rescuer:  acting during an emergency.  acting in good faith with good intentions.  acting without compensation.  not guilty of malicious misconduct or gross negligence toward the victim. o Grant immunity against lawsuits  Touching another person without his or her consent is known as battery. Chapter 2  Series of actions that a bystander should make upon first arriving at a scene (ordering question): o Recognize the emergency. o Decide to help. o Call 9-1-1 if EMS is needed. o Check the victim. o Give first aid.  Why bystanders are less likely to offer help in public (LIST OUT THE REASONS): o lack knowledge o are confused about what is or isn’t an emergency o think someone else will act o it’s easier to just avoid the situation o are uncomfortable stepping out of their comfort zone  Types of personal protective equipment & what they protect against: o Most common PPE – gloves (to protect the victim and responder from infectious diseases), breathing barrier (protect the victim and responder from diseases), eye protection o Gowns/aprons (protection from bodily fluids)  Stages of the grieving process (ordering question): o Denial o Anger o Bargaining o Depression o Acceptance Chapter 3  Functions and composition of the body systems o Most important organs:  Lungs  Heart  Brain  Spinal cord o Circulatory system  Blood—carries nutrients, oxygen, and infection fighters  Heart—pumps blood through the vessels to body; powerful, hollow, and muscular  Blood vessels (arteries and veins) o Nervous system  This system keeps the body in touch with the outside world  Nerves control all our muscles o Central nervous system—the brain  The brain is a highly specialized organ that requires considerable oxygen  Spinal nerves at different levels regulate activities of various parts of the body  Impulses go in and out o Skeletal system  206 bones  Bone is living  Give structure and protection  Facilitates movement  Creates red blood cells o Muscular system o Respiratory system  Mechanics of breathing  Inhalation—diaphragm contracts  Exhalation—diaphragm relaxes o Oxygen from air is made available to the blood through the respiratory system. o Respiratory rates are controlled by the brain  Cyanosis: a bluish discoloration of the skin resulting from poor circulation or inadequate oxygenation of the blood  Difference between arteries & veins o Arteries—oxygenated elastic, muscular tubes that pump/spurt blood away from the heart o Veins—deoxygenated; carry blood back to the heart (blood flows back to the heart)  Difference between red blood cells, white blood cells, and platelets o Red blood cells—carry oxygen o White blood cells—prevent infections o Platelets—essential for blood clot formation  Part of the body that’s vulnerable to injury if a victim has a back or neck injury: spinal column  Different types of muscle: o Voluntary muscles (controlled by the person) also known as skeletal muscles o Smooth muscles (very little control by the person) o Cardiac muscle (found only in the heart) Chapter 4  Purpose of each of the 5 parts of the victim assessment (scene size-up, primary check etc) and the order in which they are performed (matching question and an ordering question) o Scene size-up  Purpose: to assess the environment for your safety and for others’ safety  Check for hazards, violence or weapons, and dangerous substances o Primary check  Purpose: to assess the victim for obvious life-threatening conditions  Check for circulation, breathing/airway, and severe bleeding o Check responsiveness  Purpose: Assessing the victim’s responsiveness can give you insight as to whether or not the victim has experienced brain damage  Alert victim, tap victim’s shoulder, ask the victim “What’s your name? Do you know what’s going on?”  Shout in both ears o Secondary check  Purpose: to assess secondary (physical) conditions  For a responsive victim: Ask if he or she can feel or wiggle the fingers and toes.  For an unresponsive victim: Check spinal cord with Babinski reflex text (take a pen and) use the pen to put pressure in a j- shape around the heel—curling of toes is normal; fanning or splaying of toes is abnormal) o Signs and symptoms  Purpose: to further assess the victim’s physical condition  Signs—things that the responder can see, feel, hear, touch, smell  Symptoms—things the victim feels and describes—what is their chief complaint?  RAP-CAB (checking a responsive victim) o R = Responsiveness (assess) o A = Activate EMS (call 9-1-1) o P = Position (position the victim on his/her back) o A = Airway (open the airway) o B = Breathing (assess) o C = Circulation (assess)  Method used for opening the airway of an unresponsive victim: head tilt chin lift  Indications of a breathing problem o Snoring—airway partially blocked (usually by tongue) o Gurgling (breaths passing through liquid)—fluids in throat o Crowing (noisy creak or squeak)—spasm of the larynx; foreign body o Wheezing—spasm or partial obstruction in bronchi (asthma, emphysema) o Occasional gasping breaths (known as agonal respirations)—breathing after the heat has stopped  Positioning of victims (unresponsive, not breathing & unresponsive, breathing) o Unresponsive, not breathing: position the victim on his back o Unresponsive, but breathing: Haines (recovery) position  Arm position: keep left arm straight, extended above the head; right arm crosses the chest under the left cheek  Leg position: bend the right knee and pull it across the body (this will roll the victim towards you)  DOTS o D = Deformity o O = Open wounds o T = Tenderness o S = Swelling  Purpose of medical identification tags: to identify a medical condition or allergies the victims may have  Triage & order of treatment for victims: the process of prioritizing multiple victims o Immediate care o Delayed care o “Walking dead” o Dead Chapter 5  Difference between a heart attack and cardiac arrest o Heart attack—heart muscle tissue dies due to blood supply reduction or cessation o Cardiac arrest—heart stops beating  Steps for identifying and treating an unresponsive adult (ordering question): o Recognition and action o CPR o AED o Advanced care o Post-arrest care  When to call 911 if alone with an unresponsive adult, child and infant victim: o Unresponsive adult: call 9-1-1 immediately o Unresponsive infant or child: give 30 compressions and 2 breaths before calling 9-1-1  Difference in chest compressions between adults, children and infants o Adults: at least 2”; 2 hands o Children: about 2”; 1 hand o Infant: 1.5”; 2 fingers  Technique for the Heimlich maneuver o Locate navel o Fist with the thumb side against the victim’s abdomen (above the navel) o Grasp the fist with your other hand o Thrust inward and upward (in a scooping motion)  Technique for Heimlich maneuver on an obese victim: place your hand at the base of the breast bone and thrust your hand Chapter 6  Victim’s chance of survival greatly improves through what: early CPR and AED (earlier = greater chance for survival)  When is defibrillation most effective: when the pads are placed correctly on the victim and no one is touching the victim while the AED analyzes the heart rhythm  Difference between ventricular fibrillation and tachycardia o ventricular fibrillation—most common abnormal heart rhythm in cases of sudden cardiac arrest in adults o ventricular tachycardia—heart beats too fast to pump blood  Using an AED (steps) o Power on the AED o Remove clothing or jewelry o Place pads on victim o Stand clear o Analyze heart rhythm o Shock advised o Stand clear o Press shock button o Perform CPR o Follow AED prompts!!  Considerations to remember when using an AED: o Water o Children (size of pads) o Medication patches o Implanted devices (such as pacemakers) Chapter 7  Perfusion vs hypoperfusion o Perfusion—adequate blood and oxygen are provided to all cells in the body o Hypoprofusion—the cardiovascular system collapses and fails; blood circulation decreases and eventually ceases  Sides of the perfusion triangle o Heart o Blood (content function) o Blood vessels (container function)  Stages of shock o Compensated shock  Compensation for blood loss o Decomposed shock  Late stage of shock  Falling blood pressure o Irreversible shock  Final stage  terminal  General care for victims in shock: o Monitor breathing o Position the victim  No spinal injury: Put them in the shock position (lying down flat on their back with head raised)  Unresponsive/stroke: Put them in the Haines position  Victims with breathing difficulties, chest injuries, or heart attack: Place the victim in a half-sitting position  Suspected injury or leg fracture: Keep the victim completely flat (back and head to the ground) o Seek immediate medical care o Loosen tight clothing o Handle with care (watch out for splint bone or joint injuries)  General care for anaphylaxis o Call 9-1-1 immediately o Administer epinephrine o Monitor breathing  Care for psychogenic shock (fainting) o If someone feels like they’re about to faint, have them lie down or sit down—do NOT have them place their head between their knees o If someone faints:  Check for breathing  Begin CPR and call 9-1-1 if necessary  Keep the victim flat  Check for possible head and spine injuries  Raise legs 6 to 12 inches unless an injury is suspected Chapter 8 Amount of blood loss that can lead to shock or death when lost rapidly o Loss of 1 quart in adult o Loss of 1 pint in child Hemorrhaging: Loss of a large quantity of blood in a short amount of time Difference between arterial, venous, and capillary bleeding o Arterial—spurting o Venous—flowing o Capillary--oozing What effects clotting time (i.e. what can slow clotting time): temperature Care for external bleeding: o Protect yourself with gloves!
