Which abbreviation corresponds to the meaning 'As needed'?

Explanation:
Understanding dosing abbreviations is essential for interpreting how meds are given. PRN stands for pro re nata, meaning “as needed.” When a medication is labeled PRN, it isn’t scheduled at fixed times; the dose is given in response to the patient’s symptoms or clinical need, often with safeguards like a maximum daily amount or minimum intervals. This differs from other timing abbreviations: four times daily means the medicine is scheduled every 6 hours; once daily means it’s given once every day; at bedtime means it’s given once in the evening. PRN is the only one that indicates dosing based on need rather than a set clock.
