Nursing Elites

1. A client with chronic renal failure is receiving epoetin alfa (Epogen). Which laboratory test should the nurse monitor to evaluate the effectiveness of this medication?

• A. White blood cell count.
• B. Hemoglobin and hematocrit.
• C. Platelet count.
• D. Blood urea nitrogen (BUN) and creatinine.

Correct answer: B

Rationale: The correct answer is B: Hemoglobin and hematocrit. These are the primary laboratory tests to monitor the effectiveness of epoetin alfa (Epogen) in treating anemia. White blood cell count (A), platelet count (C), and blood urea nitrogen (BUN) and creatinine (D) are not directly related to the effects of this medication. Epoetin alfa stimulates the production of red blood cells, so monitoring hemoglobin and hematocrit levels helps assess the response to the treatment.

2. A client with a history of diabetes mellitus is admitted with a blood glucose level of 600 mg/dL. What type of insulin should the nurse prepare to administer to this client?

• A. Regular insulin
• B. NPH insulin
• C. Lispro insulin
• D. Glargine insulin

Correct answer: A

Rationale: In a client with a blood glucose level of 600 mg/dL, which indicates severe hyperglycemia or diabetic ketoacidosis, the nurse should prepare to administer regular insulin (A). Regular insulin has a rapid onset of action and is the preferred choice for immediate correction of high blood glucose levels. NPH insulin (B), lispro insulin (C), and glargine insulin (D) are not suitable for the rapid correction of severe hyperglycemia.

3. A client with frequent urinary tract infections (UTIs) asks the nurse about drinking juice daily to prevent future UTIs. Which response is best for the nurse to provide?

• A. Orange juice has vitamin C, which deters bacterial growth.
• B. Apple juice is the most useful in acidifying the urine.
• C. Cranberry juice stops pathogens' adherence to the bladder.
• D. Grapefruit juice increases the absorption of most antibiotics.

Correct answer: C

Rationale: Cranberry juice is known for its ability to prevent urinary tract infections by reducing the adherence of Escherichia coli bacteria to the cells within the bladder. This property helps in maintaining urinary tract health and preventing recurrent UTIs. Choices A, B, and D are incorrect because while vitamin C in orange juice may have some benefits, it is not specifically known for deterring bacterial growth in the urinary tract. Apple juice does not significantly impact urine acidity, and grapefruit juice does not enhance antibiotic absorption, making them less effective choices for preventing UTIs compared to cranberry juice.

4. After an adult had an indwelling catheter removed, the nurse catheterizes them as ordered and obtains 200 cc of urine. What is the best interpretation of this finding?

• A. Is voiding normally.
• B. Has urinary retention.
• C. Has developed renal failure.
• D. Needs an indwelling catheter.

Correct answer: B

Rationale: The finding of obtaining 200 cc of urine after catheterization indicates urinary retention, as the bladder did not empty completely after the first void. This situation may require further assessment and intervention to address the issue of incomplete bladder emptying. Choice A is incorrect because voiding normally would indicate a larger amount of urine output. Choice C is incorrect as renal failure would typically present with other signs and symptoms. Choice D is incorrect as the presence of urinary retention does not necessarily mean the need for an indwelling catheter immediately.

5. During a 30-second interval, the nurse counts six respirations, and the client coughs three times. In repeating the count for a second 30-second interval, the nurse counts eight respirations. What respiratory rate should the nurse document?

• A. 14
• B. 16
• C. 17
• D. 28

Correct answer: B

Rationale: The nurse should document a respiratory rate of 16. The second count of eight respirations in a 30-second interval is the most accurate as it was not interrupted by the client coughing. Therefore, this rate reflects the client's typical respiratory pattern and should be documented. Choices A, C, and D are incorrect as they do not consider the interruption caused by the client coughing during the first count, which could have affected the accuracy of the result. The second count of eight respirations provides a more reliable indication of the client's respiratory rate.
