Which of the following best describes 'prn' orders in healthcare settings?

The term 'prn' is derived from the Latin phrase "pro re nata," which translates to "as needed." This is commonly used in healthcare settings to indicate that a medication or treatment should be administered only when it is necessary for the patient's condition or symptoms, rather than on a fixed schedule.

When healthcare providers write a 'prn' order, they are providing guidance to administer the medication based on the patient's specific needs, which can vary from situation to situation. For example, a patient may be prescribed pain relief medication to be taken prn, meaning they can take it when they feel pain but do not need to take it at regular intervals if they are not in discomfort. This allows for personalized care that adapts to the patient's immediate circumstances.
