When preparing a client for transfer to the ICU for placement of a pulmonary artery catheter, the nurse should explain that this catheter is used to monitor which of the following conditions?
- A. Intracranial pressure
- B. Spinal cord perfusion
- C. Renal function
- D. Hemodynamic status
Correct Answer: D
Rationale: The correct answer is D: Hemodynamic status. A pulmonary artery catheter is used to monitor hemodynamic parameters such as cardiac output, pulmonary artery pressure, and central venous pressure. This helps assess the patient's circulatory status and guide interventions in critically ill patients.
Explanation:
1. Pulmonary artery catheter measures cardiac output and helps in assessing the heart's ability to pump blood effectively.
2. It provides information on pulmonary artery pressure which reflects the pressure in the right side of the heart and pulmonary circulation.
3. Central venous pressure is also monitored, indicating the fluid status and right heart function.
Summary:
A: Intracranial pressure - Incorrect. Pulmonary artery catheter does not monitor intracranial pressure.
B: Spinal cord perfusion - Incorrect. Pulmonary artery catheter does not monitor spinal cord perfusion.
C: Renal function - Incorrect. Pulmonary artery catheter does not monitor renal function.
