The nurse is caring for a new client that got admitted to the unit for fevers.
The client takes propylthiouracil (PTU) at home.
The nurse understands that the client is taking propylthiouracil (PTU) to treat which of the following conditions?

Choice A rationale

Not giving the medication and notifying the provider can cause unnecessary delays in treatment.

Choice B rationale

Administering the medication without checking the expiration date can result in administering an ineffective or harmful medication.

Choice C rationale

There is no need to notify the provider if the medication is already prescribed and not expired.

Choice D rationale

Checking the medication's expiration date ensures the medication is safe to administer and effective.

Choice A rationale

While metformin is commonly used as a first-line medication for type 2 diabetes, this choice does not specifically address a critical safety concern related to metformin.

Choice B rationale

Metformin can interact with contrast dyes used in imaging studies, increasing the risk of acute renal failure due to lactic acidosis. Patients need to be aware of this interaction to avoid potential complications.

Choice C rationale

Metformin is used to lower blood glucose levels, not increase them. This choice is incorrect.

Choice D rationale

While metformin is associated with less weight gain compared to other diabetes medications, this choice does not address the critical interaction with contrast dye.
