The nurse is caring for a patient following surgery whose central venous pressure (CVP) monitor indicates low pressures. Which of the following actions should the nurse anticipate implementing?
- A. Increase the IV fluid infusion rate.
- B. Administer IV diuretic medications.
- C. Elevate the head of the patient's bed to 45 degrees.
- D. Document the CVP and continue to monitor.
Correct Answer: A
Rationale: A low CVP indicates hypovolemia and a need for an increase in the infusion rate. Diuretic administration will contribute to hypovolemia and elevation of the head may decrease cerebral perfusion. Documentation and continued monitoring is an inadequate response to the low CVP.

The nurse is assessing a patient with a central venous catheter notes the catheter insertion site is red and tender with the patient's temperature 38.8°C (101.8°F). Which of the following actions should the nurse implement?
- A. Administer analgesics and antibiotics.
- B. Check the site frequently for any swelling.
- C. Discontinue the catheter and culture the tip.
- D. Change the flush system and monitor the site.
Correct Answer: C
Rationale: The information indicates that the patient has a local and systemic infection caused by the catheter and the catheter should be discontinued. Changing the flush system, administration of analgesics, and continued monitoring will not help prevent or treat the infection. Administration of antibiotics is appropriate, but the line should still be discontinued to avoid further complications such as endocarditis.
The nurse is caring for a patient who is in cardiogenic shock requiring an intra-aortic balloon pump (IABP). Which of the following assessment findings indicates that the goals of treatment with the IABP are being met?
- A. Heart rate of 110 beats/minute
- B. Urine output of 20 mL/hour
- C. Cardiac output (CO) of 5 L/minute
- D. Stroke volume (SV) of 40 mL/beat
Correct Answer: C
Rationale: A CO of 5 L/minute is normal (range is 4-8 L/minute) and indicates that the IABP has been successful in treating the shock. The low SV signifies continued cardiogenic shock. The tachycardia and low urine output also suggest continued cardiogenic shock.
The nurse is monitoring for the effectiveness of treatment for a patient with left ventricular failure. Which of the following assessments is most important for the nurse to evaluate?
- A. Mean arterial pressure (MAP)
- B. Systemic vascular resistance (SVR)
- C. Pulmonary vascular resistance (PVR)
- D. Pulmonary artery occlusive pressure (PAOP)
Correct Answer: D
Rationale: PAOP reflects left ventricular end diastolic pressure (or left ventricular preload). Because the patient in left ventricular failure will have a high PAOP, a decrease in this value will be the best indicator of patient improvement. The other values would also provide useful information, but the most definitive measurement of improvement is a drop in PAOP.
The nurse is caring for a patient with heart failure requiring a ventricular assist device (VAD) implanted and is waiting for cardiac transplantation. Which of the following actions should the nurse include in the plan of care?
- A. Administer of immuno-suppressive medications.
- B. Monitor the surgical incision for signs of infection.
- C. Teach the patient the reason for continuous bed rest.
- D. Prepare the patient to have the VAD in place permanently.
Correct Answer: B
Rationale: The insertion site for the VAD provides a source for transmission of infection to the circulatory system and requires frequent monitoring. Patients with VADs are able to have some mobility and may not be on bed rest. The VAD is a bridge to transplantation, not a permanent device. Immuno-suppression is not necessary for nonbiological devices like the VAD.
A patient has a nursing diagnosis of disturbed sleep pattern related to difficulty maintaining sleep state. Which of the following actions should the nurse include in the plan of care?
- A. Discontinue assessments during the night to allow uninterrupted sleep.
- B. Administer prescribed sedatives or opioids at bedtime to promote sleep.
- C. Silence monitor alarms to allow 30- to 40-minute rest periods.
- D. Cluster nursing activities so that the patient has uninterrupted rest periods.
Correct Answer: D
Rationale: Clustering nursing activities and providing uninterrupted rest periods will minimize sleep-cycle disruption. Sedative and opioid medications tend to decrease the amount of rapid eye movement (REM) sleep and can contribute to sleep disturbance and disturbed sensory perception. Silencing the alarms on the cardiac monitors would be unsafe in a critically ill patient, as would discontinuing assessments during the night.
