Question 1 of 5
The nurse is preparing to administer the fourth dose of IV vancomycin to a client. Which set of laboratory values would alert the nurse to hold the vancomycin and notify the health care provider?
Correct Answer: D
Rationale: A vancomycin trough of 23 mg/L is above the therapeutic range (10-20 mg/L), indicating potential toxicity. Elevated creatinine (1.5 mg/dL) suggests renal impairment, which increases the risk of vancomycin accumulation and nephrotoxicity.

Fair diabetic control
8%-9%
Poor diabetic control
>9%
Platelets
150,000-400,000/mm3
(150-400 × 109/L)

(3.9-6.1 mmol/L)
Question 2 of 5
The nurse reviews new laboratory results for assigned clients. Which finding is the priority for the nurse to report to the supervising registered nurse?
Correct Answer: C
Rationale: A serum glucose of 65 mg/dL indicates hypoglycemia, which is critical in a client on total parenteral nutrition, as it may require immediate adjustment of glucose infusion or administration of dextrose.

Question 3 of 5
An infant is to be admitted with severe diarrhea. Which room assignment is best for this infant?
Correct Answer: A
Rationale: A private room prevents transmission of infectious diarrhea to others. Proximity to the station, sharing with a non-infectious patient, or another diarrheal infant increases risks.
Question 4 of 5
During the initial home visit, a nurse is discussing the care of a client newly diagnosed with Alzheimer's disease with family members. Which of these interventions would be most helpful at this time?
Correct Answer: D
Rationale: Alzheimer's disease, a progressive chronic illness, greatly challenges caregivers. The nurse can be of greatest assistance in helping the family to use communication strategies to enhance their ability to relate to the client.

Question 5 of 5
The nurse is calculating a client's intake and output for the shift. How many mL should the nurse record as the client's net fluid balance? Record your answer using a whole number.
Correct Answer: 655 mL
Rationale: 1. Intake:
Oral: 180 + 240 + 360 = 780 mL
IV: 1000 + 75 + 250 = 1325 mL
Total Intake = 780 + 1325 = 2105 mL
2. Output:
Stool: 150 mL
Urine: 1300 mL
Total Output = 1450 mL
3. Net Balance:
2105 − 1450 = 655 mL net positive balance
