During an annual physical exam, an older adult tells the nurse of using goldenseal as an herbal supplement. Which additional history should the nurse gather from the client?

A. Administer sucralfate once a day, preferably at bedtime: Sucralfate is typically administered multiple times a day, not just once. It is commonly given in divided doses, often four times a day, to ensure adequate coverage and effectiveness. Administering it at bedtime alone would not provide consistent therapeutic effects.
B. Monitor for electrolyte imbalance: Sucralfate is not known to cause significant electrolyte imbalances. It works locally in the gastrointestinal tract and does not usually affect electrolyte levels, so monitoring for electrolyte imbalances is not a primary concern with this medication.
C. Assess for secondary Candida infection: While sucralfate may affect the gastrointestinal flora, secondary Candida infections are not a common side effect. Sucralfate is not an antibiotic and does not typically lead to fungal infections.
D. Give sucralfate on an empty stomach: Sucralfate should be administered on an empty stomach, ideally 1 hour before meals or 2 hours after meals. This allows the medication to properly adhere to the ulcer site and form a protective barrier, enhancing its effectiveness in treating peptic ulcers.

A) Takes metformin hydrochloride for type 2 diabetes mellitus: Metformin can interact with the contrast dye used in CT scans, particularly in patients with impaired renal function. The contrast dye can affect kidney function, potentially leading to lactic acidosis in patients taking metformin. It is important to follow up on this history and possibly temporarily discontinue metformin and monitor kidney function before and after the procedure.

B) Metal hip prosthesis was placed twenty years ago: A metal hip prosthesis does not typically affect the CT scan with contrast, though it may affect the imaging technique or quality. This history usually does not require follow-up related to the contrast use.
C) Report of client's sobriety for the last five years: Sobriety does not directly impact the use of contrast dye in a CT scan. This information is relevant for overall health but not specifically for the use of contrast.
D) CT scan that was performed six months earlier: The timing of a previous CT scan is not a contraindication for a new scan with contrast. Follow-up on the history of a prior scan may be relevant for comparison but does not specifically impact the use of contrast dye.
