A nurse is preparing to implement a client's prescription for hydrocortisone acetate cream, apply topically to facial rash twice a day. The nurse should ask the provider to add which of the following to the medication prescription?

A. Dose/strength: The prescription is missing the specific concentration of hydrocortisone (e.g., 1% or 2.5%), which is essential for safe and accurate administration. B. Time/frequency: The prescription already includes "twice a day," which provides clear instructions on timing and frequency. C. Route: "Apply topically" is included, indicating the route of administration is already specified. D. Medication name: "Hydrocortisone acetate cream" is clearly stated, so the medication name does not require clarification.
