A nurse is caring for a client who has quadriplegia from a spinal cord injury and reports having a severe headache. The nurse obtains a blood pressure reading of 210/108 mm Hg and suspects the client is experiencing autonomic dysreflexia. Which of the following actions should the nurse take first?
Administer a nitrate antihypertensive.
Obtain the client's heart rate.
Assess the client for bladder distention.
Place the client in a high-Fowler's position.
The Correct Answer is D
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.

Correct Answer is D
Explanation
Choice A Reason: This choice is incorrect because flatened neck veins are not a sign of cardiac tamponade. Cardiac tamponade is a condition in which fluid accumulates in the pericardial sac that surrounds the heart, causing compression and impaired filling of the heart chambers. This leads to reduced cardiac output and hypotension. One of the manifestations of cardiac tamponade is distended neck veins due to increased venous pressure and impaired venous return.
Choice B Reason: This choice is incorrect because bradycardia is not a sign of cardiac tamponade. Bradycardia is a condition in which the heart rate is slower than normal (less than 60 beats per minute). It may be caused by various factors such as vagal stimulation, medication side effects, hypothyroidism, or sinus node dysfunction. It may cause symptoms such as fatigue, dizziness, or syncope, but it does not indicate cardiac tamponade.
Choice C Reason: This choice is incorrect because sudden lethargy is not a specific sign of cardiac tamponade. Lethargy is a condition in which the person feels tired, sluggish, or drowsy. It may be caused by various factors such as sleep deprivation, depression, infection, anemia, or hypoglycemia. It may affect the person's mental and physical performance, but it does not indicate cardiac tamponade.
Choice D Reason: This choice is correct because muffled heart sounds are a sign of cardiac tamponade. Muffled heart sounds are heart sounds that are fainter or softer than normal due to reduced transmission of sound waves through fluid-filled pericardial sac. They may indicate that the heart function is compromised by cardiac tamponade and require immediate intervention such as pericardiocentesis (removal of fluid from pericardial sac).
Correct Answer is A
Explanation
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.
