A nurse in a prenatal clinic is caring for a client who has a new prescription for nystatin cream 100,000 units/g to the affected area. The nurse should recognize that which of the following elements of the prescription requires clarification by the provider?

A. Frequency of administration: The prescription does not specify how often the nystatin cream should be applied, which is essential for ensuring therapeutic effectiveness and preventing under- or over-treatment. Clarification from the provider is necessary to establish a safe and effective dosing schedule. B. Concentration of the medication: The prescription lists nystatin 100,000 units/g, which is a standard and appropriate concentration for topical treatment of fungal infections. This component does not require clarification. C. Name of the medication: The medication is clearly identified as nystatin cream, so there is no ambiguity regarding the drug being prescribed. No clarification is needed. D. Route of administration: The prescription specifies topical application to the affected area, which is standard for nystatin cream. This route is appropriate and does not require further clarification.
