Nursing Elites

1. The nurse is providing teaching to a patient who will begin taking a cephalosporin to treat an infection. Which statement by the patient indicates a need for further teaching?

• A. I may stop taking the medication if my symptoms clear up.
• B. I should eat yogurt while taking this medication.
• C. I should stop taking the drug and call my provider if I develop a rash.
• D. I will not consume alcohol while taking this medication.

Correct answer: A

Rationale: Patients should take all of an antibiotic regimen even after symptoms clear to ensure complete treatment of the infection.

2. 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.

3. Laboratory findings indicate that a client's serum potassium level is 2.5 mEq/L. What action should the nurse take?

• A. Inform the healthcare provider of the need for potassium replacement.
• B. Prepare to administer a glucose-insulin-potassium replacement.
• C. Change the plan of care to include hourly urinary output measurement.
• D. Instruct the client to increase daily intake of potassium-rich foods.

Correct answer: A

Rationale: A serum potassium level of 2.5 mEq/L is critically low, indicating severe hypokalemia. The immediate action the nurse should take is to inform the healthcare provider of the need for potassium replacement. Option B, preparing to administer glucose-insulin-potassium replacement, is not the first-line intervention; it may be considered in specific situations but requires a healthcare provider's prescription. Option C, changing the plan of care to include hourly urinary output measurement, is not the priority when managing critically low potassium levels. Option D, instructing the client to increase daily intake of potassium-rich foods, is not appropriate in this acute situation where immediate intervention is needed to address the dangerously low potassium level.

4. The client with chronic renal failure is receiving instruction on dietary restrictions. Which of the following food items should the client be instructed to avoid?

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

Correct answer: A

Rationale: The correct answer is A: Bananas. Bananas are high in potassium, and individuals with chronic renal failure are often advised to limit potassium intake to prevent hyperkalemia. Apples, rice, and potatoes are lower in potassium and can be included in moderation in the diet of clients with chronic renal failure.

5. In a patient with diabetes, which of the following is a sign of hypoglycemia?

• A. Polydipsia
• B. Polyuria
• C. Dry skin
• D. Sweating

Correct answer: D

Rationale: Sweating is a common sign of hypoglycemia in patients with diabetes. When blood sugar levels drop too low, the body releases stress hormones like adrenaline, leading to symptoms such as sweating, shakiness, and palpitations. Polydipsia (excessive thirst) and polyuria (excessive urination) are more commonly associated with hyperglycemia (high blood sugar levels) in diabetes. Dry skin is not a typical symptom of hypoglycemia.
