A nurse is teaching a class about safe medication administration. The nurse should include in the teaching that which of the following references are acceptable for safe medication administration? (Select all that apply.)

A. Documents medication administration prior to administering it: Documenting medication administration before actually administering it is incorrect and can lead to errors in documentation. The nurse should document medication administration after ensuring the medication is given to the client.

B. Verifies the medication against the prescription and medication label: This is a correct action. The nurse should verify the medication against the prescription and medication label to ensure accuracy before administering it.

C. Checks the provider's orders and confirmed dosage in a medication reference guide: This is a correct action. The nurse should check the provider's orders and confirm the dosage in a reliable medication reference guide to ensure accuracy before administering the medication.

D. Scans the barcode on the medication administration record and the client's armband: This is a correct action. Scanning the barcode on the medication administration record and the client's armband helps ensure the "Five Rights" of medication administration: right patient, right medication, right dose, right route, and right time.

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.
