There is one article from the journal - Pain Management Nursing.
Nurses’ opinions on appropriate administration of prn range opioid analgesic orders for acute pain.
Nurses' Opinions on Appropriate Administration of PRN Range Opioid Analgesic Orders for Acute Pain
At page 135, one example of prn range analgesic administration is as follows:
A range order reads morphine 2 to 8 mg IV every 2 h PRN. The patient receives the following doses: 2 mg
at 12:00 (no relief); 3 mg at 13:30 (no relief); 6 mg at 14:00. A next dose can be given as early as what time? The appropriate or preferred response is 15:30 or 16:00 As 6 mg was given at 14:00, according to q2h, the preferred administration time would be 16:00. What is the rationale of also considering 15:30 as appropriate or preferred? Obviously only 1.5 hours passed. Certainly, the 6 mg given at 14:00 is not a maximum dose. Can anyone please explain the rationale?
