A nurse is preparing to administer buspirone 7.5 mg PO every 12 hr to a client. The amount available is buspirone 15 mg/tablet. How many tablets should the nurse administer per dose?

(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

A. "Gradually decrease the dose once tolerance to the effect is reached." - Gradually decreasing the dose may help mitigate daytime sedation, but it's not the most appropriate initial response. Additionally, it should be done under the guidance of a healthcare provider.

B. "Take most of the daily dose at bedtime." - This response is appropriate because diphenhydramine commonly causes drowsiness, and taking most of the dose at bedtime can help minimize daytime sedation.

C. "Take the medication with meals." - Taking diphenhydramine with meals may reduce the risk of gastrointestinal upset but is unlikely to significantly decrease daytime sedation.

D. "Distribute the doses evenly throughout the day." - This approach may not effectively minimize daytime sedation because diphenhydramine's sedative effects are prolonged and may persist throughout the day if taken at regular intervals. Taking most of the dose at bedtime is a more practical strategy.

A. Dilute the medication with sterile water before injecting: Phenytoin should not be diluted before administration because it may cause precipitation or crystallization of the drug, leading to potential adverse effects such as tissue irritation or embolism.

B. Administer the medication over 1 min: Phenytoin should be administered slowly over 1 to 2 minutes to reduce the risk of adverse effects such as hypotension or cardiac arrhythmias. Rapid infusion can lead to cardiovascular collapse.

C. Slow the injection if the medication crystallizes: If the medication crystallizes, the nurse should stop the injection immediately and flush the IV line with normal saline. However, preventing crystallization by administering the medication slowly over the recommended time is preferable.

D. Follow the IV injection with sterile water: Following the IV injection with sterile water is not a standard practice for administering phenytoin. Instead, the nurse should follow institutional guidelines for flushing the IV line after medication administration, typically with normal saline.
