Question 1 of 5
The client diagnosed with methicillin-resistant Staphylococcus aureus (MRSA) is receiving the aminoglycoside antibiotic vancomycin. Peak and trough levels are ordered for the dose the nurse is administering. Which priority intervention should the nurse implement?
Correct Answer: C
Rationale: Trough levels must be drawn before the next vancomycin dose to ensure therapeutic levels and avoid toxicity; this is the priority. Diarrhea, peak levels, or culture reports are secondary.
Question 2 of 5
The nurse is administering the long-acting insulin glargine (Lantus) to the client at 2200. The nurse asks the charge nurse to check the dosage. Which action should the charge nurse implement?
Correct Answer: B
Rationale: Verifying MAR against syringe dosage ensures accuracy, per safety protocols. Timing questions, error forms, or HCP notification are unnecessary unless errors occur.
Question 3 of 5
The client is receiving the angiotensin-converting enzyme (ACE) inhibitor enalapril (Vasotec). When would the nurse question administering this medication?
Correct Answer: B
Rationale: A persistent cough is a common ACE inhibitor side effect, warranting discontinuation or HCP evaluation. Potassium, BP, or urine output are less critical.
