The hospital pharmacy receives a medication order for patient Jolene Smith, DOB 4/23/1986, for Keflex 250 mg qid. The medication order is dated today and is signed electronically by Ms. Smith's physician. What additional information is needed before this medication can be administered?

A. AP's name: The physician has already signed the order electronically, which fulfills the requirement for authorized prescriber identification. The specific name may be on record in the electronic health system. B. Number of refills: Refills are typically necessary for outpatient prescriptions, not for inpatient medication orders where the dosing is managed daily by healthcare staff. C. Patient's social security number: A social security number is not required for medication administration. Patient identification can be verified with full name and date of birth. D. Route of administration: The route (e.g., oral, IV) is essential for proper medication administration. Without this information, the nurse cannot safely give the drug. Keflex can be administered orally or intravenously, so clarification is necessary.
