A client is receiving tamsulosin, an alpha-adrenergic blocking agent, for the management of urinary retention due to benign prostatic hyperplasia (BPH). Which instruction is most important for the nurse to provide?

Choice A reason: Taking tamsulosin early in the day is not necessary. Tamsulosin should be taken approximately 30 minutes after the same meal each day to ensure consistent absorption and effectiveness1. The timing of the dose is less critical than ensuring it is taken after the same meal daily.

Choice B reason: Tamsulosin can cause orthostatic hypotension, which is a sudden drop in blood pressure when standing up from a sitting or lying position. This can lead to dizziness or fainting. Therefore, it is crucial to instruct patients to stand and sit up slowly to prevent falls and injuries.

Choice C reason: Reducing daily fluid intake is not recommended for patients taking tamsulosin. Adequate hydration is important for overall health and can help manage urinary symptoms associated with BPH. There is no evidence suggesting that fluid restriction improves the effectiveness of tamsulosin.

Choice D reason: Tamsulosin should be taken daily, not on a twice-a-week dosing schedule. Consistent daily dosing is necessary to maintain stable blood levels of the medication and ensure its effectiveness in managing urinary retention due to BPH.

Choice A reason:

A CT scan performed six months earlier does not typically require follow-up unless there were specific findings or complications from the previous scan. The timing of the previous scan is not a contraindication for a new CT scan with contrast. However, it is always good practice to review previous imaging results to compare and assess any changes.

Choice B reason:

Metformin hydrochloride is a medication used to manage type 2 diabetes mellitus. It is important to follow up on this information because metformin can interact with the contrast dye used in CT scans. The combination can increase the risk of lactic acidosis, a rare but serious complication. Therefore, it is crucial to assess kidney function and possibly withhold metformin before and after the procedure to reduce this risk.

Choice C reason:

A report of the client’s sobriety for the last five years is generally a positive aspect of their medical history and does not require follow-up in the context of a CT scan with contrast. Sobriety does not impact the safety or efficacy of the contrast dye used in the scan.

Choice D reason:

A metal hip prosthesis placed twenty years ago is relevant information but does not typically require follow-up before a CT scan. Unlike MRI, where metal implants can cause issues, CT scans are generally safe for patients with metal prostheses. However, the presence of metal can sometimes affect the quality of the images, so it is important for the radiologist to be aware of it.
