CCS CCS Hemodynamics & Cardiac Monitoring 1

Question 1

Normal cardiac output (CO) in a resting adult is approximately:

Accepted Answer

4–8 L/min

Answer

1–2 L/min

Answer

2–3 L/min

Answer

10–12 L/min

Question 2

Which hemodynamic parameter best reflects left ventricular preload?

Accepted Answer

Pulmonary artery wedge pressure (PAWP)

Answer

Systemic vascular resistance (SVR)

Answer

Cardiac index (CI)

Answer

Mean arterial pressure (MAP)

Question 3

A patient's arterial waveform shows pulsus paradoxus greater than 10 mmHg. This finding is most consistent with:

Accepted Answer

Cardiac tamponade

Answer

Aortic stenosis

Answer

Mitral regurgitation

Answer

Hypertrophic cardiomyopathy

Question 4

Mean arterial pressure (MAP) is calculated using which formula?

Accepted Answer

MAP = DBP + 1/3 (SBP – DBP)

Answer

MAP = (SBP + DBP) / 2

Answer

MAP = SBP – DBP

Answer

MAP = CO × SVR / 80

Question 5

Elevated systemic vascular resistance (SVR) in a patient with low cardiac output most likely indicates:

Accepted Answer

Cardiogenic shock

Answer

Septic shock

Answer

Anaphylactic shock

Answer

Distributive shock

Question 6

Which waveform component on a pulmonary artery catheter tracing represents atrial contraction?

Accepted Answer

a wave

Answer

c wave

Answer

v wave

Answer

x descent
