2025 CARDIOVASCULAR CPAN PACU
NURSING MINUTES REVIEW EXAM WITH
COMPLETE QUESTIONS AND CORRECT
ANSWERS RATED A+
ANESTHESIA affects on heart Correct Answer arrhythmias 60%
- usually resolve
PVC, increase irritability
decreased conduction time (slower rate or new 1AVB)
decreased contractility (affects stroke volume, drops cardiac
output)
-decreased CO
-decreased vascular tone (dt vasodilation)
-decrease pre load
-anesthesia suppresses cardiovascular and peripheral vascular
systems
Adrenergic Drugs Correct Answer drugs that stimulate the
sympathetic nervous system (fight /flight response). releases
norepinephrine - causes vasoconstriction and increase HR
alpha, b1 (heart), b2 (lungs), dopamine (kidneys)
alpha receptors Correct Answer adrenergic receptors that are
found in smooth muscles
3-10mcg/kg/min - will have pressor affect. alpha and b1 affects.
increase HR, contractility, pulm dilation, increase CO
11-20mcg/kg/min - increase contractility with hypotension. alpha
affect (above 10 get alpha affects)
Dobutamine Correct Answer <5mg/kg/min - low dose, beta 1
affect - improve contractility. used in HEART FAILURE
*remember that - used to get heart pumping
-increase HR, increases CO
5-20mcg/kg/min - b1 contractility, vasodilation, increase HR,
decrease in SVR, CO
*helpful in HR failure pts
nicotinic receptors Correct Answer
muscarinic receptors Correct Answer stimulate smooth muscle
and slow the heart rate
-decrease HR, AV block, bronchial constriction, tear constriction,
decreased contractility, salivation, ENT secretions
atropine and glyco block muscarinic receptors Correct Answer
