Question 1

During a right heart catheterization, the pulmonary artery wedge pressure (PAWP) is used to estimate which pressure?

Accepted Answer

Left ventricular end-diastolic pressure

Answer

PAWP approximates left ventricular end-diastolic pressure (LVEDP) when the mitral valve is normal, reflecting left heart filling pressures.

Question 2

Which vascular access site is MOST associated with retroperitoneal hemorrhage as a complication?

Accepted Answer

Femoral artery above the inguinal ligament

Answer

High femoral puncture above the inguinal ligament can lacerate vessels in the retroperitoneal space, making hemorrhage difficult to detect and compress.

Question 3

The Fick method for calculating cardiac output requires measurement of which values?

Accepted Answer

Oxygen consumption and arteriovenous oxygen difference

Answer

The Fick equation divides oxygen consumption (VO2) by the arteriovenous oxygen content difference to yield cardiac output.

Question 4

A patient develops sudden hypotension and elevated jugular venous pressure immediately after a coronary intervention. The MOST likely diagnosis is:

Accepted Answer

Cardiac tamponade

Answer

Cardiac tamponade classically presents with hypotension, elevated venous pressure, and muffled heart sounds (Beck's triad) after perforation.

Question 5

Which radiation protection principle states that dose decreases with the square of the distance from the source?

Accepted Answer

Inverse square law

Answer

The inverse square law means doubling your distance from the X-ray source reduces radiation exposure to one-quarter.
