Which is the correctly written instruction for Morphine 10 mg IM q 4 hr prn pain?

• A. Give Morphine 10 milligrams intramuscularly every 4 hours as needed for pain
• B. Morphine 10 milligrams intramuscularly every 2 hours as needed for pain
• C. Administer Morphine 10 mg IV every 4 hours
• D. Give Morphine 5 milligrams intramuscularly every 4 hours as needed for pain

Answer: (A)

Interpreting this order comes down to matching the four parts: dose, route, frequency, and the PRN instruction. The instruction given specifies a 10 milligram dose, to be given by intramuscular injection, every 4 hours, as needed for pain. The best-written version exactly mirrors all of that: give Morphine 10 milligrams intramuscularly every 4 hours as needed for pain. This keeps the dose and route correct, uses the proper interval, and preserves the PRN condition. The other phrasings differ in ways that would not align with the order: one uses the wrong route (IV instead of IM), another uses a smaller dose (5 mg instead of 10 mg), and another uses a more frequent interval (every 2 hours instead of every 4 hours). Always ensure the dose, route, and timing match the prescribed instructions, and administer PRN only when pain is present while monitoring for safety.
