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

Answer and Explanation

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 ["125"]

Explanation

Step 1: Determine the total time required to infuse 40 mEq at a rate of 10 mEq/hr.

40 mEq ÷ 10 mEq/hr = 4 hours

Result: 4 hours

Step 2: Determine the infusion rate in mL/hr.

500 mL ÷ 4 hours = 125 mL/hr

Result: 125 mL/hr

The nurse should set the IV pump to deliver 125 mL/hr.

A. Administer a nitrate antihypertensive. B. Obtain the client's heart rate. C. Assess the client for bladder distention. D. Place the client in a high-Fowler's position.

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.
