A nurse is caring for a client who is obese. The client is crying and states, "Everyone is staring at me because of my weight." Which of the following responses should the nurse make?

Rationale:

A. “I can infuse the medication at a faster rate”: Vancomycin must be infused slowly, typically over 60–120 minutes, to prevent adverse effects such as Red Man Syndrome. Increasing the infusion rate is unsafe and not appropriate.

B. “I can start the medication 30 minutes earlier.” Medications such as IV antibiotics (including vancomycin) must be administered within an acceptable time window to maintain therapeutic drug levels and effectiveness. The standard safe administration window is typically ±30 minutes from the scheduled time. Therefore, giving the medication 2 hours early is not appropriate, but 30 minutes earlier is acceptable and safe.

C. “I have up to 2 hours after the usual scheduled time to give you this medication”: While some medications have extended windows, IV antibiotics like vancomycin require strict timing, and a 2-hour delay is not appropriate.

D. “I can adjust the time and schedule for when it's convenient for you.” While patient preferences are important, antibiotic timing must align with dosing schedules to maintain therapeutic levels. Adjustments must follow clinical guidelines, not personal convenience.

Rationale:

A. “Use an electric razor when shaving while taking this medication.” Warfarin increases bleeding risk by inhibiting vitamin K–dependent clotting factors. Using an electric razor reduces the chance of cuts and bleeding during shaving, making this a critical safety teaching point.

B. “This medication can cause back pain” Back pain is not a common or expected side effect of warfarin. If a client on warfarin experiences unexplained back pain, it should be evaluated as it could indicate internal bleeding, but it is not typical enough to be part of routine teaching.

C. "Take the last dose of the day 1 hour before bedtime” Warfarin is usually taken once daily, preferably at the same time, but timing in relation to bedtime is not required. The key is consistency and regular INR monitoring to guide dosing.

D. “Avoid taking the medication with milk products” Unlike some antibiotics, warfarin’s absorption is not significantly affected by dairy. Dietary consistency with vitamin K is more important than avoiding milk, and milk products are not contraindicated.
