A nurse is preparing to administer vancomycin IV to a client. Which of the following medications may interact with vancomycin?
Nitroglycerin
Furosemide
Calcium chloride
Morphine
The Correct Answer is B
A. Nitroglycerin: Nitroglycerin is a vasodilator used to treat angina and does not have known interactions with vancomycin. Concurrent use does not increase the risk of vancomycin toxicity or adverse effects.
B. Furosemide: Furosemide is a loop diuretic that can be nephrotoxic and ototoxic, similar to vancomycin. Using both medications concurrently increases the risk of kidney damage and hearing loss, requiring careful monitoring of renal function and auditory status.
C. Calcium chloride: Calcium chloride is used for hypocalcemia and cardiac stabilization but does not interact directly with vancomycin. No enhanced toxicity or adverse reaction is expected when these drugs are administered together.
D. Morphine: Morphine is an opioid analgesic with no direct interaction with vancomycin. While both drugs may depress the central nervous system in different ways, morphine does not increase the risk of vancomycin-related nephrotoxicity or ototoxicity.

Correct Answer is A
Explanation
A. "I will notify your provider of your decision.": Informing the provider ensures that the client’s refusal is documented and that the healthcare team can discuss alternatives or address potential risks. This approach respects client autonomy while maintaining safety.
B. "Most people feel better after they have taken these medications.": This statement attempts to persuade the client rather than explore their reasons for refusal, which may not address underlying concerns or promote informed decision-making.
C. "If you do not take your medications, you will not recover.": Using scare tactics can create fear or mistrust and is not an effective way to encourage adherence. It does not support patient-centered care.
D. "Why are you refusing your medications?": Asking "why" can come across as judgmental and may make the client defensive. Open-ended, nonjudgmental questions are more effective for understanding the client’s perspective.
Correct Answer is ["1.5"]
Explanation
Calculation:
- Calculate the total dose in milligrams (mg).
Ordered dose: 0.02 mg/kg
Patient weight: 30 kg
Total dose (mg) = 0.02 mg/kg x 30 kg
= 0.6 mg.
- Calculate the volume to administer in milliliters (mL).
Total dose: 0.6 mg
Available concentration: 0.4 mg/mL
Volume (mL) = Total Dose (mg) / Available Concentration (mg/mL)
= 0.6 mg / 0.4 mg/mL
= 1.5 mL.
