A client with benign prostatic hyperplasia receives a new prescription of tamsulosin. Which intervention should the nurse perform to monitor for an adverse reaction?

Choice A reason: Notifying the healthcare provider of the carbamazepine level is not necessary, as 8.4 mg/L (35.6 mcmol/L) is within

the normal range of 4 to 12 mg/L (16.9 to 50.8 mcmol/L). The healthcare provider may adjust

the dose based on other factors such as clinical response, seizure frequency, or adverse effects,

but not based on this level alone.

Choice B reason: Administering the carbamazepine as prescribed is the appropriate action to take, as 8.4 mg/L (35.6 mcmol/L) is within

the normal range of 4 to 12 mg/L (16.9 to 50.8 mcmol/L). The nurse should follow the prescribed

dose and schedule of carbamazepine to maintain a therapeutic level and prevent seizures.

Choice C reason: Assessing the client for side effects of carbamazepine is important, as carbamazepine can cause adverse effects such as drowsiness, dizziness, nausea, rash, or blood dyscrasias. However, this action is not related to the carbamazepine level, as side effects can occur at any level and may not correlate with the serum concentration. The nurse should monitor the client for side effects regardless of the carbamazepine level.

Choice D reason: Withholding this dose of carbamazepine is not appropriate, as 8.4 mg/L (35.6 mcmol/L) is withinthe normal range of 4 to 12 mg/L (16.9 to 50.8 mcmol/L). Withholding the dose may cause a drop in the serum concentration and increase the risk of seizures. The nurse should administer the carbamazepine as prescribed unless instructed otherwise by the healthcare provider.

Choice A reason: Breast feeding is not recommended while taking this medication, as isotretinoin can pass into breast milk and harm the nursing infant. However, this information is not as important as choice d, as the client may not be breast feeding or planning to breast feed.

Choice B reason: Baseline liver function results must be obtained during therapy, as isotretinoin can cause liver damage and increase liver enzymes. However, this information is not as important as choice d, as the client may not have liver problems or need liver function tests.

Choice C reason: Do not take multiple vitamins that contain vitamin A while taking this drug, as isotretinoin is a derivative of vitamin A and can cause vitamin A toxicity if taken in excess. However, this information is not as important as choice d, as the client may not take multiple vitamins or have vitamin A toxicity.

Choice D reason: Discontinue this medication one month before attempting to conceive, as isotretinoin can cause severe birth defects and miscarriages if taken during pregnancy. Therefore, this information is most important for the nurse to provide this client, as the client is planning to become pregnant and should avoid isotretinoin exposure.
