A nurse is transcribing new medication prescriptions for a group of clients. For which of the following prescriptions should the nurse contact the provider for clarification?

A. Hydrochlorothiazide is a thiazide diuretic commonly prescribed for hypertension and edema. The dose of 12.5 mg twice daily is within an acceptable range. Although diuretics are often given in the morning to prevent nocturia, this order is clear and complete, so no clarification is required. B. Zolpidem is a sedative-hypnotic used for insomnia. The prescription clearly states the dose, route, and timing (at bedtime). This is a standard and complete order. C. This is a nasal corticosteroid used for allergic rhinitis. The prescription includes the medication, dose, route (intranasal), frequency, and specific instructions, making it clear and appropriate. D. The nurse should clarify this prescription because the dose is written as “.5 mg” without a leading zero. According to safe medication administration practices, a leading zero (0.5 mg) must be used to prevent dosing errors. Without it, the dose could be misread as 5 mg, which could result in overdose. This violates safety standards and requires clarification before administration.
