Which transcription of a prescription for ranitidine is correct?

The correct transcription for the prescription of ranitidine is "Ranitidine 150 mg PO at bedtime." This option clearly conveys the medication's name, dosage, route of administration, and the timing for taking the medication.

Using "mg" instead of "mcg" is crucial here, as ranitidine is typically prescribed in milligrams, not micrograms. The abbreviation “PO” (per os) indicates that the medication should be taken orally, which is standard for ranitidine. Specifying "at bedtime" provides clear guidance on when to take the medication, aligning with usual prescribing practices for ranitidine to prevent nighttime gastric acid secretion.

This transcription adheres to standard medical conventions for clarity and precision, which is essential for ensuring patient safety and effective communication among healthcare providers. It avoids potential misinterpretation that could occur if the timing or dosage were not specified correctly, as seen in other choices.
