Ferrous sulfate elixir is prescribed for a client with iron deficiency anemia. Which instruction should the nurse provide this client about taking the liquid medication?

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.

Choice A reason:

Those with allergies to chamomile, ragweed, or yarrow should not take feverfew because feverfew belongs to the Asteraceae/Compositae family, which includes these plants. Individuals allergic to these plants may experience allergic reactions to feverfew, such as skin rashes, swelling, and difficulty breathing. It is crucial to avoid feverfew in these cases to prevent severe allergic reactions.

Choice B reason:

Feverfew may interact with aspirin or nonsteroidal anti-inflammatory drugs (NSAIDs), but this is not the most critical information compared to potential allergic reactions. Feverfew can inhibit platelet aggregation, which may increase the risk of bleeding when taken with NSAIDs or aspirin. However, the primary concern remains the potential for severe allergic reactions in sensitive individuals.

Choice C reason:

Abdominal pain, gas, nausea, vomiting, and diarrhea can occur when taking feverfew, but these side effects are generally mild and manageable. While it is important to inform clients about possible gastrointestinal side effects, the risk of allergic reactions in individuals sensitive to chamomile, ragweed, or yarrow is more critical.

Choice D reason:

Increased anxiety and nervousness have been reported by those taking feverfew, but these side effects are less common and typically not severe. The primary concern should be the potential for allergic reactions, which can be life-threatening.
