Are there any institutions that permit range orders for PRN medications? More specifically, ranges in dose (not frequency). If so, how are these range orders interpreted when it comes to times of administration?
For example, if a patient is prescribed oxycodone 5-10 mg PO q6 hours PRN pain, the patient is administered one dose of oxycodone 5 mg at 0900 and then another dose of 5 mg at 1200 because their pain is not controlled, when can they be administered another dose of oxycodone? Is it from the first dose of administration or from the last dose administered?
Also, if able to share what their specific institutional policies are pertaining to range orders (and how to interpret them), that would be appreciated!
