CIEMT QUIZ 4 ACTUAL STUDY GUIDE / 80+ QUESTIONS AND CORRECT ANSWERS 2025/2026 GRADED A+ LATEST UPDATE .

1. PerfusionTriangle CORRECT ANSWER -The heart (the pump) -The blood vessels (the container) -The blood (content) When a patient is in shock, one or more of the three parts is not working properly. 2. Cardiogenic Shock CORRECT ANSWER 1.Caused by inadequate function of the heart, or pump failure 2. A major effect is the backup of blood into the pulmonary vessels. 3. The resulting buildup of pulmonary fluid is called pulmonary edema. 3.Obstructive Shock CORRECT ANSWER 1.Caused by a mechanical obstruction that prevents an adequate volume of blood from filling the heart chambers 2. Three of the most common examples CORRECT ANSWER a. Cardiac tamponade (pericardial tamponade) b. Tension pneumothorax c. Pulmonary embolism 4. CardiacTamponade CORRECT ANSWER -Collection of fluid between the pericardial sac and the myocardium (pericardial effusion) becomeslarge enough to prevent ventriclesfrom filling with blood. -Caused by blunt or penetrating trauma -Signs and symptoms are referred to as Beck's triad. 5. Beck'sTriad CORRECT ANSWER Signs of cardiac tamponade CORRECT ANSWER -Hypotension with a narrowed pulse pressure -Jugular venous distention (JVD) -Muffled heart sounds 6. Tension Pneumothorax CORRECT ANSWER -Caused by damage to lung tissue -Air normally held within the lung escapes into the chest cavity. -The lung collapses, and air applies pressure to the organs, including the heart and great vessels. 7. Pulmonary Embolism CORRECT ANSWER -A blood clot or air bubble that blocks the flow of blood through pulmonary vessels -If massive it can result in complete backup of blood in the right ventricle -Leads to catastrophic obstructive shock and complete pump failure 8. Distributive Shock CORRECT ANSWER 1.Results when there is widespread dilation of small arteri- oles, small venules, or both 2.The circulating blood volume pools in the expanded vascular beds and tissue perfusion decreases. Includes septic shock, neurogenic shock, anaphylactic shock, and psychogenic shock 9. Septic Shock CORRECT ANSWER a. Occurs as a result of severe infections, usually bacterial, in which toxins are generated by the bacteria b.Widespread dilation of vessels, combined with plasma loss through the injured vessel walls, results in shock. 10. Neurogenic Shock CORRECT ANSWER a. Usually the result of high spinal cord injury b.Musclesin the walls of the blood vessels are cut offfrom the sympathetic nervous system and nerve impulses that cause them to contract. c. All vessels below the level of the spinal cord injury dilate widely, increasing the size and capacity of the vascular system, causing blood to pool. 11. Anaphylactic Shock CORRECT ANSWER a.Occurs when a person reacts quickly to a substance to which he or she had been sensitized i. Sensitization means becoming sensitive to a substance that did not initially cause a reaction. ii. Each subsequent exposure after sensitization tends to produce a more severe reaction. 12. Psychogenic Shock CORRECT ANSWER a.Results when the patient has had a sudden reaction of the nervous system that produces a temporary, generalized vasodilation, resulting in syncope 13. Hypovolemic Shock CORRECT ANSWER -Result of an inadequate amount of fluid or volume in the circulatory system -Hemorrhagic causes and nonhemorrhagic causes 14. Hemorrhagic Shock CORRECT ANSWER a form of hypovolemic shock that occurs when the body loses a significant amount of blood 15. Nonhemorrhagic Shock CORRECT ANSWER a form of hypovolemic shock that occurs when the body loses a significant amount of fluid and electrolytes 16. Stages of Shock CORRECT ANSWER 1.Compensated shock CORRECT ANSWER early stage when the body can still compensate for blood loss 2. Decompensated shock CORRECT ANSWER late stage when blood pressure is falling 3. Irreversible shock CORRECT ANSWER terminal stage 17. Identifying andTreating Cardiogenic Shock CORR
