Nursing Elites

1. A client who has just undergone a skin biopsy is listening to discharge instructions from the nurse. The nurse determines that the client has misunderstood the directions if the client indicates that as part of aftercare he plans to:

• A. Use the antibiotic ointment as prescribed
• B. Return in 7 days to have the sutures removed
• C. Apply cool compresses to the site twice a day for 20 minutes
• D. Call the physician if excessive drainage from the wound occurs

Correct answer: C

Rationale: The correct answer is C. Applying cool compresses to the site twice a day for 20 minutes is not a recommended aftercare practice for a skin biopsy. After a skin biopsy, it is important to keep the dressing dry and in place for a minimum of 8 hours. Choice A is correct as using the antibiotic ointment as prescribed is a common post-biopsy instruction to prevent infection. Choice B is also correct as returning in 7 days to have the sutures removed is part of the typical follow-up care after a skin biopsy. Choice D is correct as it is important to call the physician if excessive drainage from the wound occurs to prevent complications.

2. Which clients are at risk for kidney problems? (Select all that apply.)

• A. Clients taking synthetic creatine supplements
• B. Clients taking metformin for diabetes mellitus
• C. Clients taking high-dose nonsteroidal anti-inflammatory drugs (NSAIDs) for chronic back pain
• D. Clients taking prenatal vitamins and using albuterol nebulizers

Correct answer: A

Rationale: Clients who take synthetic creatine supplements, metformin, and high-dose or long-term NSAIDs are at risk for kidney dysfunction. Synthetic creatine supplements can cause kidney damage, metformin may rarely cause lactic acidosis leading to renal impairment, and high-dose NSAIDs can lead to acute kidney injury. Prenatal vitamins and albuterol nebulizers are not known to significantly impact kidney function, thus do not pose a risk for kidney problems.

3. 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.

4. A 70-kg adult with chronic renal failure is on a 40-g protein diet. The client has a reduced glomerular filtration rate and is not undergoing dialysis. Which result would give the nurse the most concern?

• A. Albumin level of 2.5 g/dL
• B. Phosphorus level of 5 mg/dL
• C. Sodium level of 135 mmol/L
• D. Potassium level of 5.5 mmol/L

Correct answer: A

Rationale: In chronic renal failure, a protein-restricted diet is crucial to prevent the buildup of waste products. A low albumin level (<3.5 g/dL) indicates inadequate protein intake, raising concern as it may lead to malnutrition and tissue breakdown. Phosphorus, sodium, and potassium levels are not directly impacted by protein intake. Phosphorus levels may elevate in renal failure, but at 5 mg/dL, it is within normal range. Sodium and potassium levels are also within normal limits and not influenced by protein restriction.

5. The nurse is providing discharge instructions to a client who is receiving prednisone 5 mg PO daily for a rash due to contact with poison ivy. Which symptoms should the nurse tell the client to report to the healthcare provider?

• A. Rapid weight gain
• B. Abdominal striae
• C. Moon faces
• D. Gastric irritation

Correct answer: A

Rationale: Rapid weight gain can indicate fluid retention, which is a serious side effect of prednisone and should be reported.
