A nurse is caring for a child who has a penicillin allergy.
Which of the following prescriptions should the nurse verify with the provider?

Choice A rationale:

Blood glucose levels are not typically affected by rifampin and pyrazinamide. These medications are primarily used to treat tuberculosis and do not have a direct impact on blood sugar levels.

Choice B rationale:

Thyroid function studies are not usually required when a patient is on rifampin and pyrazinamide. These medications do not typically affect the thyroid gland or its function.

Choice C rationale:

Liver function tests are crucial when a patient is on rifampin and pyrazinamide. Both of these medications can cause liver problems, including hepatitis. Therefore, regular monitoring of liver function is necessary to detect any potential damage early and adjust the treatment plan accordingly.

Choice D rationale:

Gallbladder studies are not typically required for patients on rifampin and pyrazinamide. These medications do not have a known direct impact on the gallbladder.

Choice A rationale:

The client stating, “I haven’t had anything to eat or drink since last night” is not a cause for concern. This is because patients are often advised to fast before undergoing certain medical procedures or tests, including an intravenous pyelogram (IVP).

Fasting helps to ensure that the test results are accurate and not influenced by recent food or drink consumption.

Choice B rationale:

The client expressing that “The last time I voided it was painful” could be related to their recurrent kidney stones. Kidney stones can cause discomfort or pain during urination. However, this statement does not necessarily require additional data collection in the context of an IVP. The pain could be a symptom of the kidney stones rather than a contraindication for the IVP1.

Choice C rationale:

The statement “I took my metformin before breakfast” is of concern. Metformin is a medication used to treat type 2 diabetes. It is important for the nurse to collect additional data about this statement because metformin can potentially interact with the iodine-based contrast dye used in an IVP. This interaction can increase the risk of lactic acidosis, a serious and potentially lifethreatening condition. Therefore, patients are often advised to stop taking metformin before and for a couple of days after having an IVP12. Choice D rationale:

The client mentioning, “I took a laxative yesterday” is not necessarily alarming. Laxatives are often used before an IVP to clear the bowels, which helps to ensure clear images during the procedure. Therefore, this statement does not require additional data collection in the context of an IVP1.
