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. Avoid flossing the teeth to prevent gum irritation: There is no evidence to suggest that flossing the teeth increases the risk of gum irritation with phenytoin use. In fact, proper dental hygiene, including flossing, is essential to prevent gum disease, which can be exacerbated by the medication.

B. Alcohol increases the chance of phenytoin toxicity: Consumption of alcohol can increase the risk of phenytoin toxicity by enhancing its effects. Therefore, clients taking phenytoin should avoid alcohol consumption to prevent adverse effects and ensure the medication's efficacy.

C. Take an antacid with the medication if indigestion occurs: Phenytoin can interact with antacids, reducing its absorption and effectiveness. Therefore, clients should not take antacids concurrently with phenytoin unless directed by their healthcare provider.

D. Phenytoin turns urine blue: Phenytoin does not typically cause changes in urine color. This statement is incorrect and not relevant to the client's medication regimen.

Alprazolam is a benzodiazepine medication commonly used to treat anxiety and insomnia. Here's the rationale for each option:

A. "Avoid activities that require alertness, such as driving.": Alprazolam can cause drowsiness and impair cognitive function, so it's essential for clients to avoid activities that require alertness, such as driving or operating heavy machinery, while taking this medication. Providing this instruction promotes safety and prevents accidents.

B. "Monitor for peripheral edema.": Peripheral edema is not a common side effect of alprazolam. This instruction is not relevant to the use of this medication.

C. "Take this medication with a high-fat meal.": Alprazolam can be taken with or without food, but taking it with a high-fat meal may delay its absorption. Therefore, it is not necessary to instruct the client to take it with a high-fat meal, especially since this may affect the medication's effectiveness.

D. "Take this medication every night before sleep.": While alprazolam may be used to treat insomnia, it is not typically recommended for nightly use due to the risk of dependence and tolerance. Using it nightly can lead to addiction and withdrawal symptoms if abruptly stopped. Therefore, this instruction is not appropriate.
