Nursing Elites

1. In a 46-year-old female client admitted for acute renal failure secondary to diabetes and hypertension, which test is the best indicator of adequate glomerular filtration?

• A. Serum creatinine.
• B. Blood urea nitrogen (BUN).
• C. Sedimentation rate.
• D. Urine specific gravity.

Correct answer: A

Rationale: The correct answer is A: Serum creatinine. Creatinine is a product of muscle metabolism that is filtered by the glomerulus. Blood levels of creatinine are not affected by dietary or fluid intake, making it a reliable indicator of kidney function. An elevated creatinine level strongly suggests nephron loss, indicating decreased glomerular filtration rate. Choice B, Blood Urea Nitrogen (BUN), reflects the amount of urea nitrogen in the blood and can be influenced by factors other than kidney function, such as protein intake and liver health, making it less specific for evaluating glomerular filtration. Choice C, Sedimentation rate, is a measure of how quickly red blood cells settle in a test tube and is not a direct marker of kidney function. Choice D, Urine specific gravity, mainly reflects the kidney's ability to concentrate urine and is not a direct indicator of glomerular filtration rate. Therefore, Serum creatinine is the most appropriate test to assess glomerular filtration in this scenario.

2. The nurse is caring for a client with chronic renal failure who is on a low-potassium diet. Which of the following foods should the client avoid?

• A. Bananas
• B. Potatoes
• C. Rice
• D. Apples

Correct answer: A

Rationale: Bananas are high in potassium content, which can lead to hyperkalemia in clients with chronic renal failure who are on a low-potassium diet. Therefore, it is crucial for these clients to avoid bananas. Potatoes, rice, and apples are lower in potassium compared to bananas and are generally considered safe for consumption in clients with chronic renal failure on a low-potassium diet.

3. The nurse is caring for a client with chronic renal failure who is receiving peritoneal dialysis. Which of the following findings should be reported immediately to the physician?

• A. Clear dialysate outflow.
• B. Increased blood pressure.
• C. Cloudy dialysate outflow.
• D. Decreased urine output.

Correct answer: C

Rationale: Cloudy dialysate outflow should be reported immediately to the physician. It is indicative of peritonitis, a severe infection of the peritoneal cavity and a serious complication of peritoneal dialysis. Prompt medical attention is crucial to prevent further complications or systemic infection. Clear dialysate outflow (Choice A) is a normal finding in peritoneal dialysis. Increased blood pressure (Choice B) and decreased urine output (Choice D) are common in clients with chronic renal failure and may not require immediate reporting unless they are significantly abnormal or accompanied by other concerning symptoms.

4. A healthcare professional is reviewing laboratory results for a client who is at risk for nephrotoxicity due to medications. Which of the following serum creatinine results does the healthcare professional document as normal?

• A. 0.2 mg/dL
• B. 1.0 mg/dL
• C. 2.8 mg/dL
• D. 3.9 mg/dL

Correct answer: B

Rationale: The normal serum creatinine level typically ranges from 0.6 to 1.3 mg/dL. A result of 1.0 mg/dL falls within this normal range. A serum creatinine level of 0.2 mg/dL is abnormally low and may indicate decreased muscle mass or malnutrition. On the other hand, results of 2.8 mg/dL and 3.9 mg/dL are elevated, signifying impaired kidney function and potential nephrotoxicity from medications.

5. A client with overflow incontinence needs assistance with elimination. What intervention should the nurse include in the plan of care?

• A. Stroke the medial aspect of the thigh.
• B. Use intermittent catheterization.
• C. Provide digital anal stimulation.
• D. Use the Valsalva maneuver.

Correct answer: D

Rationale: In clients with overflow incontinence, the voiding reflex arc is impaired. The Valsalva maneuver, which involves holding the breath and bearing down as if to defecate, can help initiate voiding by applying mechanical pressure. Options A and C (stroking the thigh or anal stimulation) rely on an intact reflex arc to trigger elimination and are not effective for clients with overflow incontinence. Intermittent catheterization (Option B) is a last resort due to the high risk of infection and should only be considered if other interventions fail.
