CEN EXAM UPDATED QUESTIONS AND
CORRECT ANSWERS.
MAP calculation - ANS [( 2xDBP) + SBP] / 3
cushing's triad - ANS widened pulse pressure, bradycardia, and irregular respirations
(indicative of increased ICP)
chronotropes - ANS affect the heart rate at the SA node (cardizem)
inotropes - ANS affect contractility (dopamine)
dromotropes - ANS affect automaticity of the heart
ACE inhibitors adverse effects - ANS dry cough, angioedema, renal impairment
ARB (sartans) - ANS block angiotensin 2 receptors, resulting in vasodilation
antidote for vasopressor extravasation - ANS phentolamine (regitine)

tx is NSAIDs
hypertensive emergency/crisis - ANS SBP >180 or DBP >120
AND
evidence of impending end-organ damage
hypertensive emergency tx - ANS nitroglycerin or nitroprusside slowly to decrease bp by 25%
in first 2 hours of tx
cardiac tamponade - ANS pericardial sac accumulates excess fluid, causing obstructive shock
