Nursing Elites

1. Which lab test is used to assess renal function?

• A. Check blood glucose levels
• B. Monitor serum creatinine
• C. Monitor BUN
• D. Check electrolyte levels

Correct answer: B

Rationale: The correct answer is B: Monitor serum creatinine. Serum creatinine is a key indicator of renal function as it reflects the glomerular filtration rate. An increase in serum creatinine levels indicates impaired kidney function. Checking blood glucose levels (choice A) is not specific to assessing renal function but is used to diagnose diabetes. Monitoring BUN (choice C) is important but not as specific as serum creatinine in assessing renal function. Checking electrolyte levels (choice D) is essential in assessing kidney function but is not as specific as monitoring serum creatinine.

2. A nurse is reviewing the laboratory results of a client who has rheumatoid arthritis and is prescribed methotrexate. Which of the following results should the nurse report to the provider?

• A. White blood cell count 8,000/mm3
• B. Platelet count 150,000/mm3
• C. Hemoglobin 14 g/dL
• D. Aspartate aminotransferase (AST) 60 units/L

Correct answer: D

Rationale: The correct answer is D: Aspartate aminotransferase (AST) 60 units/L. An elevated AST level indicates liver damage, a side effect of methotrexate, and should be reported. Choices A, B, and C are within normal ranges and do not indicate potential complications related to methotrexate therapy.

3. A nurse is caring for a client who is receiving continuous enteral feedings through a nasogastric tube. Which of the following actions should the nurse take?

• A. Keep the head of the bed elevated to 15 degrees.
• B. Change the feeding bag every 48 hours.
• C. Administer the feeding through a large-bore syringe.
• D. Flush the tube with 0.9% sodium chloride every 4 hours.

Correct answer: D

Rationale: The correct action the nurse should take is to flush the tube with 0.9% sodium chloride every 4 hours. This helps maintain patency and prevents clogs during enteral feedings. Keeping the head of the bed elevated to 15 degrees (Choice A) is important for preventing aspiration but is not directly related to tube care. Changing the feeding bag every 48 hours (Choice B) is not a standard practice as the bag should be changed every 24 hours to prevent bacterial growth. Administering the feeding through a large-bore syringe (Choice C) is incorrect as enteral feedings should be given through an appropriate feeding pump for accuracy and safety.

4. A nurse is planning care for a client who is 1 day postoperative following a hypophysectomy for the removal of a pituitary tumor. Which of the following findings requires further assessment by the nurse?

• A. Glasgow Coma Scale score of 15
• B. Blood drainage on the initial dressing measuring 3 cm
• C. Report of dry mouth
• D. Urinary output greater than fluid intake

Correct answer: D

Rationale: The correct answer is D. Urinary output greater than fluid intake could indicate diabetes insipidus, a complication following hypophysectomy. Diabetes insipidus is characterized by excessive urination and extreme thirst due to inadequate levels of antidiuretic hormone (ADH). Options A, B, and C are all expected findings in the immediate postoperative period following a hypophysectomy. A Glasgow Coma Scale score of 15 indicates the highest level of consciousness, blood drainage on the initial dressing is a common finding after surgery, and dry mouth can be a side effect of anesthesia and surgical procedures.

5. A nurse is caring for a client who has Cushing's syndrome. Which of the following findings should the nurse expect?

• A. Hypotension.
• B. Weight loss.
• C. Hyperkalemia.
• D. Hypercalcemia.

Correct answer: C

Rationale: In clients with Cushing's syndrome, the nurse should expect hyperkalemia. Cushing's syndrome is characterized by excess cortisol levels, which can lead to potassium retention and result in hyperkalemia. Choices A, B, and D are incorrect. Hypotension is not typically associated with Cushing's syndrome; instead, hypertension is more common due to the effects of cortisol. Weight gain, rather than weight loss, is a common symptom of Cushing's syndrome. Hypercalcemia is not a typical finding in Cushing's syndrome; instead, hypocalcemia may occur due to increased urinary calcium excretion.
