A nurse is providing preoperative teaching to an older adult female client who is scheduled for a laminectomy and uses supplements. Which of the following supplements should the nurse identify as increasing the client's risk for hypotension during surgery?

Rationale:

A. Place the client in a supine position: The supine position may impair respiratory function and increase discomfort, especially in terminal clients who may experience dyspnea. A semi-Fowler’s or side-lying position is often preferred for comfort and easier breathing.

B. Remind the client to eat scheduled meals daily: For clients nearing end of life, appetite naturally decreases, and forcing meals can cause distress. Care should focus on comfort, allowing the client to eat only if and when they desire rather than adhering to structured meal times.

C. Speak in a loud tone when addressing the client: Loud speech is not appropriate unless the client has documented hearing impairment. A calm, soft tone is more comforting and respectful, especially in the emotionally sensitive context of end-of-life care.

D. Offer the client a blanket to keep warm: Clients nearing the end of life often experience poor circulation and may feel cold. Providing a blanket is a comfort-focused, non-invasive intervention that promotes warmth and dignity during this phase.

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.
