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?
Probiotics
Black Cohosh
soy
Flaxseed
The Correct Answer is B
Rationale:
A. Probiotics: Probiotics are used to support gastrointestinal and immune health and do not significantly affect blood pressure or pose a known risk for intraoperative hypotension.
B. Black Cohosh: Black cohosh is often used to manage menopausal symptoms and is known to cause vasodilation, which can lower blood pressure. When combined with anesthetic agents, it can potentiate hypotensive effects during surgery.
C. Soy: Soy is consumed for its phytoestrogenic effects but does not have a direct or significant hypotensive action that increases surgical risk. Its impact on intraoperative blood pressure is minimal.
D. Flaxseed: Flaxseed may offer mild antihypertensive effects over time due to its omega-3 content, but it is not typically associated with clinically significant drops in blood pressure during surgery.

Correct Answer is B
Explanation
Rationale:
A. Apply the largest cuff available: Using a cuff that is too large for the client can yield inaccurately low readings. Cuff size should match the client’s arm circumference, not be chosen randomly or for convenience.
B. Use the palpatory method to determine blood pressure: When auscultation is difficult, the palpatory method helps estimate the systolic pressure by palpating the radial pulse. This guides proper cuff inflation and avoids missing the auscultatory gap.
C. Place the arm above the level of the client's heart: Elevating the arm above heart level can result in falsely low readings. The arm should be supported at heart level to obtain accurate results.
D. Deflate the cuff quickly: Rapid deflation can cause the nurse to miss key Korotkoff sounds, leading to an inaccurate measurement. Cuff deflation should be slow and controlled (2–3 mm Hg/sec).
Correct Answer is D
Explanation
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.
