Free RCIS Hemodynamics Questions and Answers

Question 1

What is the primary purpose of measuring the mean arterial pressure (MAP) during invasive hemodynamic monitoring?

Accepted Answer

To evaluate the adequacy of perfusion to vital organs

Answer

To assess the strength of the patient's pulse

Answer

To determine the patient's oxygen saturation level

Answer

To measure the cardiac output directly

Question 2

Which of the following factors directly affects cardiac output (CO)?

Accepted Answer

Heart rate (HR) and stroke volume (SV)

Answer

Blood viscosity and vessel length

Answer

Pulmonary resistance and left ventricular compliance

Answer

Systemic vascular resistance (SVR) and right atrial pressure

Question 3

During a right heart catheterization, an increase in pulmonary capillary wedge pressure (PCWP) may indicate which of the following conditions?

Accepted Answer

Mitral stenosis

Answer

Right ventricular failure

Answer

Hypovolemia

Answer

Chronic obstructive pulmonary disease (COPD)

Question 4

What is the formula for calculating systemic vascular resistance (SVR)?

Accepted Answer

SVR = (MAP - CVP) / CO

Answer

SVR = (CO - MAP) / CVP

Answer

SVR = (CVP - MAP) / CO

Answer

SVR = (MAP - CO) / CVP

Question 5

What hemodynamic parameter is directly measured by a Swan-Ganz catheter during a right heart catheterization?

Accepted Answer

Pulmonary artery pressure (PAP)

Answer

Left ventricular end-diastolic pressure (LVEDP)

Answer

Left atrial pressure (LAP)

Answer

Aortic pressure
