Nursing Elites

1. A nurse is caring for a client who has chronic kidney disease. The nurse should identify which of the following laboratory values as an indication for hemodialysis?

• A. Glomerular filtration rate of 14 mL/min
• B. BUN 16 mg/dL
• C. Serum magnesium 1.8 mg/dL
• D. Serum phosphorus 4.0 mg/dL

Correct answer: A

Rationale: A glomerular filtration rate (GFR) of 14 mL/min is significantly low, indicating poor kidney function and the need for hemodialysis to remove waste products effectively. BUN, serum magnesium, and serum phosphorus levels are important in assessing kidney function and electrolyte balance but are not direct indicators for the initiation of hemodialysis. BUN (blood urea nitrogen) reflects the kidney's ability to filter waste products, serum magnesium levels are important for muscle and nerve function, and serum phosphorus levels are vital for bone health.

2. A healthcare provider is providing dietary teaching to a client who has osteoporosis. Which of the following foods should the healthcare provider recommend as the best source of calcium?

• A. Broccoli
• B. Cheddar cheese
• C. Almonds
• D. Fortified orange juice

Correct answer: B

Rationale: Cheddar cheese is a rich source of calcium and should be recommended to clients with osteoporosis. While broccoli and almonds also contain calcium, cheddar cheese provides a higher amount per serving. Fortified orange juice may contain added calcium, but it is not as concentrated a source as cheddar cheese. Therefore, the best choice for a client with osteoporosis seeking a high calcium food is cheddar cheese.

3. A nurse is assessing a client who is postoperative following a thyroidectomy. Which of the following findings should the nurse report to the provider?

• A. Serum calcium level of 8 mg/dL.
• B. Urine output of 60 mL/hr.
• C. Heart rate of 110/min.
• D. Temperature of 37.5°C (99.5°F).

Correct answer: C

Rationale: The correct answer is C. A heart rate of 110/min is elevated and may indicate hypocalcemia, a potential complication following a thyroidectomy. Elevated heart rate can be a sign of hypocalcemia due to the close relationship between calcium levels and cardiac function. Option A, serum calcium level of 8 mg/dL, is within the normal range (8.5-10.5 mg/dL) and would not be a cause for concern post-thyroidectomy. Option B, urine output of 60 mL/hr, is within the normal range for urine output and not typically a priority finding post-thyroidectomy. Option D, a temperature of 37.5°C (99.5°F), is slightly elevated but not a critical finding post-thyroidectomy unless accompanied by other symptoms.

4. How should a healthcare provider monitor a patient who has been prescribed digoxin?

• A. Monitor potassium levels
• B. Monitor heart rate
• C. Check digoxin levels
• D. Check blood glucose levels

Correct answer: C

Rationale: The correct way to monitor a patient who has been prescribed digoxin is by checking digoxin levels. Digoxin is a medication used to treat various heart conditions, and monitoring its levels in the blood is crucial to prevent toxicity. Monitoring potassium levels (Choice A) is important as well, as digoxin can affect potassium levels, but checking digoxin levels is more specific to monitoring the medication itself. Monitoring heart rate (Choice B) is relevant but does not directly assess the medication levels. Checking blood glucose levels (Choice D) is not typically indicated specifically for patients prescribed digoxin.

5. A healthcare provider is reviewing laboratory results for a client who has diabetes mellitus. Which of the following tests is an indicator of long-term blood glucose control?

• A. Fasting blood glucose
• B. Glycosylated hemoglobin (HbA1c)
• C. Random blood glucose
• D. Postprandial blood glucose

Correct answer: B

Rationale: The correct answer is B, Glycosylated hemoglobin (HbA1c). HbA1c provides a measure of long-term blood glucose control over the past 2-3 months. This test reflects the average blood glucose levels during this period, making it a valuable tool in managing diabetes. Choices A, C, and D are not indicators of long-term blood glucose control. Fasting blood glucose measures the current glucose level after a period of not eating, random blood glucose provides a snapshot of the current glucose level, and postprandial blood glucose measures the glucose level after a meal.
