(Hemodynamic monitoring) Exam Actual
Questions and Answers 2026
Which hemodynamic parameter best reflects the effectiveness of
drugs that the nurse gives to reduce a patient's left ventricular
afterload?
a. Mean arterial pressure (MAP)
b. Systemic vascular resistance (SVR)
c. Pulmonary vascular resistance (PVR)
d. Pulmonary artery wedge pressure (PAWP) -
correct answer ✅ANS: B
SVR reflects the resistance to ventricular ejection, or afterload. The
other parameters may be monitored but do not reflect afterload as
directly.
When caring for a patient with pulmonary hypertension, which
parameter will the nurse use to directly evaluate the effectiveness
of the treatment?
a. Central venous pressure (CVP)
b. Systemic vascular resistance (SVR)
c. Pulmonary vascular resistance (PVR)
d. Pulmonary artery wedge pressure (PAWP) -
correct answer ✅ANS: C

Questions and Answers 2026
PVR is a major contributor to pulmonary hypertension, and a
decrease would indicate that pulmonary hypertension was
improving. The other parameters may also be monitored but do not
directly assess for pulmonary hypertension.
DIF: Cognitive Level: Apply (application)
When monitoring the effectiveness of treatment for a patient with
a large anterior wall myocardial infarction, what is the most
pertinent measurement for the nurse to obtain?
a. Central venous pressure (CVP)
b. Systemic vascular resistance (SVR)
c. Pulmonary vascular resistance (PVR)
d. Pulmonary artery wedge pressure (PAWP) -
correct answer ✅ANS: D
PAWP reflects left ventricular end diastolic pressure (or left
ventricular preload) and is a sensitive indicator of cardiac function.
Because the patient is high risk for left ventricular failure, the PAWP
must be monitored. An increase will indicate left ventricular failure.
The other values would also provide useful information, but the
