When reviewing the admitting prescriptions for a client,the nurse notes that the dose of one medication is three times the usual dose of this medication. Which of the following actions should the nurse take?

The correct action for the nurse to take is to choose option D: Contact the provider to question the dosage. This is the best course of action because the nurse has identified a potential error in the prescription, as the dose is three times the usual amount. By contacting the provider, the nurse can clarify and confirm if the dosage is indeed correct or if there has been a mistake made. This ensures patient safety and prevents any potential harm from administering an incorrect dosage.

Option A is incorrect because the nurse should not solely rely on the pharmacy's confirmation without consulting the provider directly. Option B is not the best choice as it does not address the need to verify the dosage with the prescribing provider. Option C is unsafe as it involves administering a potentially incorrect dosage without clarification.
