A nurse is reviewing new prescriptions for a group of clients. Which of the following prescriptions should the nurse clarify with the provider?

Safe medication administration relies on the elimination of transcription errors and adherence to established safety guidelines, such as avoiding trailing zeros. The Joint Commission mandates specific labeling standards to prevent dosing inaccuracies that could lead to toxicity or subtherapeutic treatment. Clarifying ambiguous or non-standard prescriptions is a fundamental responsibility of the nurse in maintaining patient safety and preventing adverse events. Rationale: A. The prescription for Clozapine 12.50 mg must be clarified because it contains a trailing zero, which is a prohibited notation according to safety standards. A trailing zero can be misread as 125 mg if the decimal point is missed, leading to a ten-fold dosing error and potential toxicity. Standard practice requires writing the dose as 12.5 mg to ensure clear communication. B. Lamotrigine 200 mg PO daily is a standard maintenance dose for the treatment of epilepsy or bipolar disorder and does not require clarification. This dosage falls within the typical therapeutic range and the notation is clear and free of dangerous abbreviations or zeros. The nurse should simply continue to monitor the patient for adverse effects like Stevens-Johnson syndrome. C. Donepezil 23 mg PO daily is an approved dosage for the treatment of moderate-to-severe Alzheimer's disease and is not inherently incorrect. While higher than the starting dose, this specific strength was developed to provide additional cognitive benefits for patients with advanced disease. The notation is clear and follows standard pharmaceutical guidelines, so no clarification is needed based on the dosage. D. Fluoxetine oral solution 20 mg/5 mL administered via a gastrostomy tube is an appropriate route and dose for a patient who cannot swallow. Liquid formulations are the preferred method for tube administration to prevent clogging and ensure the full dose of the selective serotonin reuptake inhibitor is delivered. This prescription follows clear clinical logic and standard safety practices for enteral medication.
