TNCC FULL STUDY GUIDE 2024 | TNCC TEST PREP 8TH EDITION, TNCC WRITTEN EXAM, TNCC FINAL EXAM TEST (ALL IN ONE) | VERIFIED ANSWERS | LATEST VERSION (ALREADY GRADED A+) What is vascular response? ------CORRECT ANSWER---------------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 ANSWER---------------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 - 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 ANSWER--------------- 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 ANSWER---------------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 ANSWER--------------- Tachypnea happens for 2 reasons: 1. Maintain acid-base balance 2. Maintain increased supply of oxygen What are the late observable signs of symptoms of increased ICP? ------ CORRECT ANSWER---------------- Dilated, nonreactive pupil - Unresponsiveness to verbal or painful stimuli - Abnormal motor posturing patterns - Widening pulse pressure - Increased systolic blood pressure - Changes in RR and pattern - Bradycardia What is Cushing's phenomenon or Cushing's Reflex? ------CORRECT ANSWER---------------Triad of progressive HTN, bradycardia and diminished respiratory effort. What are the two types of herniation that occurs with ICP? ------CORRECT ANSWER---------------1. Uncal herniation 2. Central or transtentorial herniation Why does herniation occur? What are the symptoms? ------CORRECT ANSWER---------------Because of uncontrolled increases in ICP. S/E's - Unilateral or bilateral pupillary dilation - AsyDimmetric pupillary reactivity - Abnormal motor posturing - Other evidence of neurologic deterioration Define uncal herniation. ------CORRECT ANSWER---------------The uncus (medial aspect of the temporal lobe) is displaced over the tentorium into the posterior fossa. This herniation is the more common of the two types of herniation syndromes. Define central or transtentorial herniation. ------CORRECT ANSWER--------- ------A downward movement of the cerebral hemispheres with herniation of the diencephalon and midbrain through the elongated gap of the tentorium. Disruptions of the bony structures of the skull can result in what? ------ CORRECT ANSWER---------------Displaced or nondisplaced fx's causing CSF leakage b/c of lac to the dura mater, creating a passage for CSF.

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: - MI - Blunt cardiac injury - Mitral valve insufficiency - dysrhythmias - Cardiac Failure Explain Obstructive Shock. ------CORRECT ANSWER---------------Results from inadequate circulating blood volume because of an obstruction or compression of great veins, aorta, pulmonary arteries, or heart itself. 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 ANSWER---------------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 ANSWER---------------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 ANSWER---------------Renal ischemia activates release of renin. Kidneys do not receive adequate blood supply, renin is release into circulation. - BP - Pulse pressure - Breath sounds - Heart sounds - Bowel sounds Percuss: - Chest and abdomen Palpate: - Central pulse (carotid or femoral) - Positive inotropic effect (force of contraction) may be evidence by a bounding central pulse - Palpate peripheral pulses - Palpate skin temp and moisture Diagnostic Procedures: - Xrays and other studies - Labs Planning and Implementation - Oxygen - IV's with warmed replacement fluids - Control external bleeding with direct pressure - Elevate LE's - NGT - Foley - Monitor and pulse oximeter - Monitor for development of coagulopathies - Surgery? ICP is a reflection of what three volumes? What happens when one increases? ------CORRECT ANSWER---------------1. Brain 2. CSF 3. Blood within the nonexpansible cranial vault As volume of one increases, the volume of another decreases to maintain ICP within normal range. As ICP rises, CPP decreases, leading to cerebral ischemia and potential for hypoxia and lethal secondary insult. Hypotensive pt w/marginally elevated ICP can be harmful. Slightly elevated BP could protect against brain ischemia in a pt with high ICP. Cerebral ischemia can lead to increased concentration of CO2 and decreased concentration of O2 in cerebral vessels. CO2 dilates cerebral blood vessels = increase blood volume and ICP.
