Acute Care Nurse Practitioner Hemodynamic Monitoring and Management 2

Question 1

Which formula correctly calculates systemic vascular resistance (SVR)?

Accepted Answer

(MAP - CVP) / CO × 80

Answer

SVR = (MAP − CVP) / CO × 80, representing the resistance the left ventricle must overcome to eject blood.

Question 2

A patient with septic shock has a persistently low MAP despite 3L of IV fluids. Which vasopressor is the first-line agent per Surviving Sepsis Campaign guidelines?

Accepted Answer

Norepinephrine

Answer

Norepinephrine is the first-line vasopressor for septic shock due to its potent alpha-adrenergic effects and favorable safety profile.

Question 3

Which measurement is MOST useful for assessing fluid responsiveness in a mechanically ventilated patient?

Accepted Answer

Pulse pressure variation (PPV)

Answer

PPV >13% during mechanical ventilation reliably predicts fluid responsiveness by reflecting preload dependency.

Question 4

A patient has a cardiac output of 3.0 L/min and a body surface area of 2.0 m². What is the cardiac index?

Accepted Answer

1.5 L/min/m²

Answer

Cardiac index = CO / BSA = 3.0 / 2.0 = 1.5 L/min/m², which is below the normal range of 2.2–4.0.

Question 5

An ACNP notes that a patient's arterial line shows a dampened waveform. Which action should be taken FIRST?

Accepted Answer

Check for air bubbles or kinks in the tubing

Answer

A dampened arterial line waveform most commonly results from air bubbles, clots, or kinks in the tubing, which should be assessed first.
