Question: After pulmonary artery catheter insertion, the nurse assesses a pulmonary artery
pressure of 45/25 mm Hg, a pulmonary artery occlusion pressure (PAWP) of 20 mm Hg, a
cardiac output of 2.6 L/min and a cardiac index of 1.9 L/min/m2. Which physician order is of the
highest priority?
a. Apply 50% oxygen via venture mask.
b. Insert an indwelling urinary catheter.
c. Begin a dobutamine (Dobutrex) infusion.
d. Obtain stat cardiac enzymes and troponin. - CORRECT ANSWER✔✔c. Begin a dobutamine
(Dobutrex) infusion.
The pulmonary pressures are higher than normal, indicating elevated preload, and the cardiac
index and output values are low. The priority order for the nurse to implement is to begin a
dobutamine (Dobutrex) infusion to improve cardiac output, possibly reducing pulmonary artery
, Page 2 of 124
occlusion pressures. The other treatments are important, but the dobutamine infusion is the
most important at this time.
Question: The nurse is caring for a patient with a pulmonary artery catheter. Assessment
findings include a blood pressure of 85/40 mm Hg, heart rate of 125 beats/min, respiratory rate
35 breaths/min, and arterial oxygen saturation (SpO2) of 90% on a 50% venturi mask.
Hemodynamic values include a cardiac output (CO) of 1.0 L/min, central venous pressure (CVP)
of 1 mm Hg, and a pulmonary artery occlusion pressure (PAOP) of 3 mm Hg. The nurse
questions which of the following physician's order?
a. Titrate supplemental oxygen to achieve a SpO2 > 94%.
b. Infuse 500 mL 0.9% normal saline over 1 hour.
c. Obtain arterial blood gas and serum electrolytes.
d. Administer furosemide (Lasix) 20 mg intravenously. - CORRECT ANSWER✔✔d. Administer
furosemide (Lasix) 20 mg intravenously.
A central venous pressure of 1 mm Hg, pulmonary artery occlusion pressure of 1 mm Hg along
with a blood pressure of 85/40 mm Hg and heart rate of 125 are indicative of a low volume
, Page 3 of 124
state. Infusion of 500 mL of 0.9% normal saline will increase circulating fluid volume.
Administration of furosemide (Lasix) is contraindicated and could further reduce circulating fluid
volume. Titrating supplemental oxygen, obtaining serum blood gas and electrolyte samples,
although not a priority, are appropriate interventions.
Question: Which of the following situations may result in a low cardiac output and low cardiac
index? (Select all that apply.)
a. Exercise
b. Hypovolemia
c. Myocardial infarction
d. Shock - CORRECT ANSWER✔✔b. Hypovolemia
c. Myocardial infarction
d. Shock
Hypovolemia, myocardial infarction, and shock often result in a decreased cardiac output.
Cardiac output is usually increased with exercise.

Question: What conditions below can result in an increased cardiac afterload?Select all that
apply:
a. Vasoconstriction
b. Aortic stenosis
c. Vasodilation
d. Dehydration
e. Pulmonary hypertension - CORRECT ANSWER✔✔a. Vasoconstriction
b. Aortic stenosis
e. Pulmonary hypertension
Question: The volume of blood in the left ventricle at the end of diastole is best described as:
a. Afterload
b. Stroke volume
