Exam Questions with Accurate
Answers
ACE Inhibitors/Angiotensin Receptor Blockers (CAD) correct answer -
Interrupts RAAS system, decreases vasoconstriction/release of
aldosterone
*Decreases afterload/demand
*Decreases fluid volume/preload/demand
Acute Coronary Syndrome correct answer all ACSs are considered to be
caused by acute disruption of a plaque.
*The severity depends on the degree and duration of occlusion.
Afterload (D) correct answer the pressure against which the ventricles
must pump to open aortic/pulmonic valves and eject the blood.
Affected by arterial resistance.
Alpha-1 Receptors (Location) correct answer located on cell
membranes of vascular smooth muscle.
-Produces vasoconstriction. Increases afterload and BP.
Alpha-2 Receptors (Location) correct answer located on vascular
smooth muscle membranes.
,-Counter-regulatory for A-1, produces vasodilation. Decreases afterload
and BP.
Angina Pectoris (D) correct answer indicates reversible myocardial
ischemia. "Supply vs Demand"... Decreased supply or increased
demand may cause angina.
-The cause is ISCHEMIA!
Angiotensin II (D) correct answer extremely potent vasodilator, RAAS.
-Released in response to decrease kidney perfusion.
Aspirin (CAD) correct answer -Anti-platelet aggregate, give 325mg for
suspicion of MI stat (reduces mortality by 50%).
-Give prophylactic post-MI
-Monitor: bleeding, metabolic acidosis or respiratory alkalosis
(overdose)
Automaticity (D) correct answer ability of cells to spontaneously initiate
an action potential.
-SA: 60-100bpm
-AV: 40-60bpm
-Purkinje: 20-40bpm
, Beta Blockers (CAD) correct answer -1st Generation: blocks B-1 and B-2
receptors (contradicted in asthma/diabetes)
-2nd Generation: block B-1 receptors, decreases response to
catecholamines stimulation
-Negative inotrope AND chronotrope
-Reduces demand and increases supply
-DECREASES MORTALITY IN AMI PATIENTS
Beta Blockers (HF) correct answer **Only in patients NOT retaining
fluid!
-Goal: control sympathetic compensatory responses
*Decrease workload and O2 consumption
*Improves diastolic function
Beta-1 Receptors (Location) correct answer located on myocardial cells.
-When stimulated causes increased CO, BP, HR, and increased force of
contraction.
Beta-2 Receptors (Location) correct answer located on bronchial
smooth muscle.
-Produces bronchial dilation, increased ventilation.
Calcium Channel Blockers (CAD) correct answer -Antianginal,
antihypertensive, antiarrythmic
