A nurse is preparing a client for transfer to the ICU for placement of a pulmonary artery catheter. The nurse should explain to the client that this catheter is used to monitor which of the following conditions?
Hemodynamic status
Spinal cord perfusion
Renal function
Intracranial pressure
The Correct Answer is A
Choice A Reason: This is correct because a pulmonary artery catheter is a device that measures the pressures and flows in the heart and lungs, such as the pulmonary artery pressure, the pulmonary artery wedge pressure, the cardiac output, and the mixed venous oxygen saturation. These parameters reflect the hemodynamic status of the client, which is the balance between the cardiac output and the systemic vascular resistance.
Choice B Reason: This is incorrect because a pulmonary artery catheter does not measure spinal cord perfusion, which is the blood flow to the spinal cord. Spinal cord perfusion can be affected by spinal cord injury, spinal anesthesia, or spinal surgery.
Choice C Reason: This is incorrect because a pulmonary artery catheter does not measure renal function, which is the ability of the kidneys to filter waste products and maintain fluid and electrolyte balance. Renal function can be assessed by urine output, blood urea nitrogen, creatinine, and glomerular filtration rate.
Choice D Reason: This is incorrect because a pulmonary artery catheter does not measure intracranial pressure, which is the pressure inside the skull. Intracranial pressure can be increased by brain injury, stroke, tumor, infection, or hydrocephalus.

Correct Answer is B
Explanation
Choice A Reason: Preventing musculoskeletal disability is important, but not the priority focus of care. The nurse should first assess and manage the client's life-threatening injuries, such as airway obstruction, bleeding, shock, or brain injury.
Choice B Reason: Airway protection is the priority focus of care for a client with multiple system trauma. The nurse should ensure that the client has a patent airway and adequate ventilation, as any compromise in these areas can quickly lead to hypoxia, respiratory failure, and death.
Choice C Reason: Stabilizing cardiac arrhythmias is also important, but not the priority focus of care. The nurse should monitor the client's cardiac rhythm and treat any arrhythmias that may occur, but only after securing the airway and breathing.
Choice D Reason: Decreasing intracranial pressure is another important goal, but not the priority focus of care. The nurse should assess the client's neurological status and intervene to prevent or reduce increased intracranial pressure, such as elevating the head of the bed, maintaining normothermia, and administering osmotic diuretics. However, these measures are secondary to ensuring adequate oxygenation and perfusion.
Correct Answer is D
Explanation
Choice A Reason: This is incorrect because administering a nitrate antihypertensive is not the first action, as it may cause a rapid drop in blood pressure and worsen the client's condition.
Choice B Reason: This is incorrect because obtaining the client's heart rate is not the first action, as it does not address the cause of autonomic dysreflexia or relieve the symptoms.
Choice C Reason: This is incorrect because assessing the client for bladder distention is not the first action, as it may take time and delay the treatment of autonomic dysreflexia.
Choice D Reason: This is correct because placing the client in a high-Fowler's position is the first action, as it lowers the blood pressure by promoting venous return and reducing cardiac preload.
