CRNA Boards Practice-Exam TEST MOD 005 with Revised
Correct Q & A 2023/2024 APPROVED
Epinephrine receptors correct answers alpha 1, alpha 2, beta 1, beta 2

Epinephrine dose correct answers IV 2-10mcg/min

Epinephrine effects correct answers increased systolic BP
- alpha receptors = vasoconstriction
- beta1 receptor = cardiac stimulant

decreased diastolic BP
- beta2 = dilation of skeletal muscle blood vessel

Phenylephrine receptors correct answers alpha 1

Phenylephrine dose correct answers 40-200 mcg/min

Phenylephrine effects correct answers vasoconstriction, and reflex bradycardia

Milrinone mechanism of action correct answers Inhibits PDE-3 → ↑cAMP
↑ cAMP in heart: ↑[Ca]cytosol → inotropic
↑ cAMP in blood vessels: ↑Ca reuptake by sarcoplasmic reticulum → vasodilation

Epinephrine mechanism of action correct answers Direct-acting alpha and beta agonist. Alpha:
vasoconstriction. Beta-1: positive inotropic, chronotropic, and dromotropic effects. Beta-2: bronchial
smooth muscle relaxation and dilation of skeletal vasculature. Blocks histamine receptors.

milrinone correct answers phosphodiesterase inhibitor

Septal leads and artery correct answers V1, V2, - LM

Inferior leads and artery correct answers II, III, aVF
RCA

Right arterial pressure (RAP) correct answers 4-8 mmHg

Pulmonary artery pressure (PAP) correct answers 15-30/5-15 mmHg

Pulmonary artery occlusive pressure (Wedge) correct answers 8-12 mmHg

Pulmonary vascular resistance (PVR) correct answers 100-250 dynes/sec/cm-5

Pulmonary vascular resistance correct answers resistance to blood flow out of the right ventricle created
by the pulmonary circulatory system
