Hypovolemia, a decrease in amount of circulating blood volume, may result from significant loss of whole blood because of hemorrhage or from loss of semipermeable integrity of cellular membrane leading to leakage of plasma and protein from intravascular space to the interstitial space (as in a burn). Some causes: - Blood loss - Burns, etc. Explain Cardiogenic Shock. - CORRECT ANSWERS Syndrome that results from ineffective perfusion caused by ineffective perfusion caused by inadequate contractility of cardiac muscle. Some causes: - MI - Blunt cardiac injury - Mitral valve insufficiency - dysrhythmias - Cardiac Failure Explain Obstructive Shock. - CORRECT ANSWERS Results from inadequate circulating blood volume because of an obstruction or compression of great veins, aorta, pulmonary arteries, or heart itself. TNCC TEST PREPA, TNCC NOTES FOR WRITTEN EXAM TNCC 8TH EDITION EXAMS WITH 100% CORRECT VERIFIED QUESTIONS AND ANSWERS LATEST DOWNLOAD 2024/2025 BEST EXAM SOLUTION GRADED A+ FOR PASS Some causes: - Cardiac tamponade (may compress the heart during diastole to such and extent that atria cannot adequately fill, leading to decreased stroke volume). - Tension pneumothorax may lead to inadequate stroke volume by displacing inferior vena cava and obstructing venous return to right atrium. - Air embolus may lead to obstruction of pulmonary artery and subsequent obstruction to right ventricular outflow during systole, with resulting obstructive shock Explain Distributive Shock. - CORRECT ANSWERS Results from disruption in SNS control of the tone of blood vessels, which leads to vasodilation and maldistribution of blood volume and flow. (Neurogenic and Septic Shock). Neurogenic shock may result from injury to spinal cord in cervical or upper thoracic region. Spinal shock = areflexia and flaccidity associated with lower motor neuron involvement in complete cord injuries; reflexes return with resolution of spinal shock. Septic shock from bacteremia is distributive shock. Endotoxins and other inflammatory mediators cause vasodilation, shunting of blood in microcirculation, and other perfusion abnormalities. What is vascular response? - CORRECT ANSWERS As blood volume decreases, peripheral blood vessels vasoconstrict as a result of sympathetic stimulation via inhibition of baroreceptors. Arterioles constrict to increase TPR and BP. What is renal response? - CORRECT ANSWERS Renal ischemia activates release of renin. Kidneys do not receive adequate blood supply, renin is release into circulation. Renin causes angiotensinogen, normal plasma protein, to release angiotensin I. Angiotensin-converting enzyme from the lungs converts into angiotensin II. TNCC TEST PREPA, TNCC NOTES FOR WRITTEN EXAM TNCC 8TH EDITION EXAMS WITH 100% CORRECT VERIFIED QUESTIONS AND ANSWERS LATEST DOWNLOAD 2024/2025 BEST EXAM SOLUTION GRADED A+ FOR PASS Angiotensin II causes: - Vasoconstriction of arterioles and some veins - Stimulation of sympathetic nervous system - Retention of water by kidneys - Stimulation of release of aldosterone from the adrenal cortex (sodium retention hormone) *Decreased urinary output = early sign renal hypoperfusion and an indicator that there's systemic hypoperfusion. Explain adrenal gland response. - CORRECT ANSWERS When adrenal glands are stimulated by SNS, release of catecholamines (epinephrine and norepinephrine) from adrenal medulla will increase. Epi stimulates receptors in heart to increase force of cardiac contraction (positive inotropy) and increase HR (positive chronotropy) to improve cardiac output, BP and tissue perfusion. Shock stimulates hypothalamus to release corticotropin-releasing hormone that stimulates pituitary to release ACTH that stimulates adrenal gland to release cortisol. Effect of cortisol release is elevation in blood sugar and increased insulin resistance and gluconeogenesis, hepatic process to produce more sugar. Cortisol also causes renal retention of water and sodium, a compensatory mechanism to conserve body water. Explain Hepatic Response. - CORRECT ANSWERS Liver can store excess glucose as glycogen. As shock progresses, glycogenolysis is activated by epi to break down glycogen into glucose.

(Neurogenic and Septic Shock). Neurogenic shock may result from injury to spinal cord in cervical or upper thoracic region. Spinal shock = areflexia and flaccidity associated with lower motor neuron involvement in complete cord injuries; reflexes return with resolution of spinal shock. Septic shock from bacteremia is distributive shock. Endotoxins and other inflammatory mediators cause vasodilation, shunting of blood in microcirculation, and other perfusion abnormalities. What is vascular response? - CORRECT ANSWERS As blood volume decreases, peripheral blood vessels vasoconstrict as a result of sympathetic stimulation via inhibition of baroreceptors. Arterioles constrict to increase TPR and BP. What is renal response? - CORRECT ANSWERS Renal ischemia activates release of renin. Kidneys do not receive adequate blood supply, renin is release into circulation. Renin causes angiotensinogen, normal plasma protein, to release angiotensin I. Angiotensin-converting enzyme from the lungs converts into angiotensin II. Angiotensin II causes: - Vasoconstriction of arterioles and some veins - Stimulation of sympathetic nervous system - Retention of water by kidneys TNCC TEST PREPA, TNCC NOTES FOR WRITTEN EXAM TNCC 8TH EDITION EXAMS WITH 100% CORRECT VERIFIED QUESTIONS AND ANSWERS LATEST DOWNLOAD 2024/2025 BEST EXAM SOLUTION GRADED A+ FOR PASS - Stimulation of release of aldosterone from the adrenal cortex (sodium retention hormone) *Decreased urinary output = early sign renal hypoperfusion and an indicator that there's systemic hypoperfusion. Explain adrenal gland response. - CORRECT ANSWERS When adrenal glands are stimulated by SNS, release of catecholamines (epinephrine and norepinephrine) from adrenal medulla will increase. Epi stimulates receptors in heart to increase force of cardiac contraction (positive inotropy) and increase HR (positive chronotropy) to improve cardiac output, BP and tissue perfusion. Shock stimulates hypothalamus to release corticotropin-releasing hormone that stimulates pituitary to release ACTH that stimulates adrenal gland to release cortisol. Effect of cortisol release is elevation in blood sugar and increased insulin resistance and gluconeogenesis, hepatic process to produce more sugar. Cortisol also causes renal retention of water and sodium, a compensatory mechanism to conserve body water. Explain Hepatic Response. - CORRECT ANSWERS Liver can store excess glucose as glycogen. As shock progresses, glycogenolysis is activated by epi to break down glycogen into glucose. In a compensatory response to shock, hepatic vessels constrict to redirect blood flow to other vital areas. Explain Pulmonary Response. - CORRECT ANSWERS Tachypnea happens for 2 reasons: 1. Maintain acid-base balance 2.

What are the seven patterns of pathway injuries related to motor vehicle accidents? - CORRECT ANSWERS Up and over, down and under, lateral, rotational, rear, roll over, and ejection. Differentiate between the three impacts of motor vehicle impact sequence. - CORRECT ANSWERS The first impact occurs when the vehicle collided with another object. The second impact occurs after the initial impact when the occupant continues to move in the original direction of travel until they collide with the interior of the vehicle or meet resistance. The third impact occurs when internal structures collide within the body cavity. What are the three factors that contribute to the damage caused by penetrating trauma's? - CORRECT ANSWERS The point of impact, the velocity and speed of impact, and the proximity to the object. What causes the primary effects of blast traumas? - CORRECT ANSWERS The direct blast effects. Types of injuries include last long, tympanic membrane rupture and middle ear damage, abdominal hemorrhage and perforation, global rupture, mild Trumatic brain injury. What causes the secondary effects of blast traumas? - CORRECT ANSWERS Projectiles propelled by the explosion. Injuries include penetrating or blunt injuries or I penetration. What causes the tertiary effects of blast traumas? - CORRECT ANSWERS Results from individuals being thrown by the blast wind. Injuries include hole or partial body translocation from being thrown against a hard service: blunt or penetrating trauma's, fractures, traumatic amputations. What causes quarternary effects of blast traumas? - CORRECT ANSWERS All explosion related injuries, illnesses, or diseases not due to the first three mechanisms. Injuries include external and internal burns, crush injuries, closed and open brain injuries, asthmatic or breathing problems from dust smoke or toxic fumes, angina, or hyper glycemia and hypertension.
