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.

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.
