A nurse is caring for a client who has nephrotic syndrome and is receiving high-dose corticosteroid therapy. For which of the following electrolyte imbalances should the nurse monitor?

Choice A reason: This is incorrect because the patient may not see a response from the medication for at least six months. The patient should continue taking the medication as prescribed and follow up with the provider regularly.

Choice B reason: This is correct because finasteride can cause birth defects in male fetuses if it is absorbed through the skin or ingested by pregnant women. The patient should wear gloves when handling the tablets and avoid contact with crushed or broken tablets.

Choice C reason: This is incorrect because PSA levels will decrease while taking this medication. PSA stands for prostate-specific antigen, which is a marker for prostate cancer. The patient should inform the provider that they are taking finasteride before having a PSA test, as it may affect the results.

Choice D reason: This is incorrect because grapefruit juice does not interact with finasteride. However, the patient should avoid alcohol and other medications that may affect the liver while taking finasteride.

The correct answer is a. Alcohol.

Choice A: Alcohol

Reason: Alcohol can significantly affect blood glucose levels in patients taking glimepiride. Both hypoglycemia (low blood sugar) and hyperglycemia (high blood sugar) can occur depending on the amount and frequency of alcohol consumption. Alcohol can enhance the blood sugar-lowering effect of glimepiride, leading to a dangerous drop in blood sugar levels, known as hypoglycemia. Symptoms of hypoglycemia include dizziness, confusion, weakness, and in severe cases, loss of consciousness. Therefore, it is advised to avoid alcohol while taking glimepiride.

Choice B: Milk

Reason: There are no known interactions between glimepiride and milk. Milk does not affect the absorption or efficacy of glimepiride. Therefore, it is generally safe to consume milk while taking this medication.

Choice C: Grapefruit juice

Reason: Grapefruit juice might theoretically increase the levels of drugs metabolized by CYP2C9, including glimepiride, due to its potential to inhibit CYP2C9 enzymes. However, this interaction has not been reported in humans and is considered unlikely to have a significant clinical impact. Therefore, grapefruit juice is not a major concern for patients taking glimepiride.

Choice D: Coffee

Reason: Coffee and other caffeinated beverages may increase blood sugar levels, which can counteract the effects of glimepiride. However, this interaction is not as significant as the interaction with alcohol. It is generally advised to monitor blood sugar levels and consume coffee in moderation while taking glimepiride.
