A nurse is talking with a client who has been taking levothyroxine to treat hypothyroidism.
The nurse should instruct the client to avoid taking which of the following over-the-counter medications within 4 hr of taking levothyroxine?

Choice Arationale:

The statement about taking the medication with food is incorrect. Nitroglycerin sublingual tablets should not be taken with food. They work much faster when absorbed through the lining of the mouth.

Choice B rationale:

The statement that the medication can slow the heart rate is incorrect. Nitroglycerin does not slow the heart rate. In fact, it can cause a reflex tachycardia, where the heart rate increases.

Choice C rationale:

The statement that the effects of the medication should be felt within 5 minutes is correct. This indicates an understanding of the instructions.

Choice Drationale:

Taking the medication every 10 minutes until the pain goes away is incorrect. Nitroglycerin sublingual tablets usually give relief in 1 to 5 minutes. However, if the pain is not relieved, a second tablet can be taken 5 minutes after the first tablet. If the pain continues for another 5 minutes, a third tablet may be used. Taking the medication every 10 minutes could lead to an overdose.

Choice A rationale:

Prednisone does not need to be taken on an empty stomach. In fact, taking it with food can help reduce stomach upset.

Choice B rationale:

Prednisone suppresses the immune system, which can make users more susceptible to infections. Therefore, reporting symptoms like a sore throat to the provider is important.

Choice C rationale:

Prednisone can cause fluid retention and high blood pressure, so increasing sodium intake would not be advisable.

Choice D rationale:

Weight gain is a common side effect of prednisone due to increased appetite and fluid retention. Weight loss is not typically expected.
