A nurse is checking for paradoxical blood pressure on a client who has constrictive pericarditis. Which of the following findings should the nurse expect?

Apical pulse rate different than the radial pulse rate

Increase in heart rate by 20% when standing

Drop in systolic BP by 20 mm Hg when moving from a lying to a sitting position

Drop in systolic BP more than 10 mm Hg on inspiration

Answer and Explanation

The Correct Answer is D

Choice A reason: An apical pulse rate different than the radial pulse rate is known as a pulse deficit, which can indicate atrial fibrillation or other cardiac arrhythmias, but it is not related to paradoxical blood pressure or constrictive pericarditis.

Choice B reason: An increase in heart rate by 20% when standing is indicative of orthostatic hypotension, not paradoxical blood pressure. This condition involves a drop in blood pressure upon standing, leading to a compensatory increase in heart rate.

Choice C reason: A drop in systolic BP by 20 mm Hg when moving from a lying to a sitting position is another indicator of orthostatic hypotension, not paradoxical blood pressure.

Choice D reason: The correct answer is d because a drop in systolic BP of more than 10 mm Hg on inspiration, known as pulsus paradoxus, is a characteristic finding in constrictive pericarditis. This occurs due to the impaired filling of the heart during inspiration, leading to a significant drop in systolic blood pressure.

Correct Answer is C

Explanation

Choice A reason: Applying lotion to the skin around the edges of the splint may increase moisture and friction, which can contribute to skin breakdown. It is better to use protective dressings to reduce friction.

Choice B reason: Turning the client every 4 hours is not frequent enough. Clients in skeletal traction should be repositioned frequently, typically every 2 hours, to prevent pressure ulcers and maintain skin integrity.

Choice C reason: The correct answer is c because padding the top of the splint with protective dressings helps reduce friction and pressure on the skin, preventing skin breakdown and ensuring the client's comfort.

Choice D reason: Applying a footplate to the bed is not directly related to preventing skin breakdown. The primary focus should be on reducing friction and pressure around the splint.

A. Place the client on a low-sodium diet. B. Encourage increased fluid intake. C. Obtain weekly weight. D. Encourage frequent ambulation.

Correct Answer is A

Explanation

Choice A reason: A low-sodium diet is essential for clients with acute glomerulonephritis to prevent fluid retention and reduce the workload on the kidneys. This dietary modification helps manage edema and hypertension, common complications of the condition. By limiting sodium intake, the body retains less water, which helps control swelling and blood pressure, making it a crucial intervention in the plan of care.

Choice B reason: Encouraging increased fluid intake is not recommended for clients with acute glomerulonephritis. Excessive fluid intake can lead to fluid overload, worsening edema and hypertension. The kidneys are already compromised in their ability to excrete fluid efficiently, so increasing fluid intake would exacerbate these issues. Instead, fluid intake should be carefully monitored and potentially restricted to prevent further strain on the kidneys.

Choice C reason: Obtaining weekly weight is not specific enough to monitor the acute phase of glomerulonephritis. Daily weights are more appropriate to closely monitor fluid balance and detect changes in edema. Daily weight measurements can help in assessing the effectiveness of interventions such as a low-sodium diet or diuretics and provide timely information for adjusting the plan of care.

Choice D reason: Encouraging frequent ambulation, while generally beneficial for overall health, is not a specific intervention for managing acute glomerulonephritis. The primary focus should be on dietary modifications and monitoring fluid balance to manage symptoms and prevent complications. Ambulation should be encouraged based on the client's overall condition and ability but is not a direct intervention for glomerulonephritis.
