Fall UPDATED ACTUAL Exam Questions
and CORRECT Answers
Normal lab values for the following: - CORRECT ANSWER - Serum Potassium 3.5-5
mEq/L
PR interval <0.20 sec (0.12-0.20)
QRS interval <0.12 sec
Central Venous Pressure (CVP) in adults 2-8 mmHg
Cardiac Output (CO) in adults 4-8L/min
Cardiac Index (CI) in adults 2.2-4L/min/m^2
MAP in adults 70-105 mmHg
Significance of the following (not required to memorize actual normal ranges): - CORRECT
ANSWER - Systemic Vascular Resistance (SVR): systemic vascular resistance→
resistance the left ventricle must overcome to perfuse body
Wedge Pressure (PAOP/PAWP): estimates the left atrial pressure by "looking through" the lungs
Stroke Volume: volume of blood pumped in one pump/stroke
Ejection fraction: ejection fraction→ percent of blood ejected from left ventricle with each beat
