What is the correct entry for a telephone prescription of morphine?

The correct entry for a telephone prescription of morphine is associated with how medications should be ordered, considering the route of administration, dosing parameters, and the need for a clear indication of when to administer the drug.

Option B specifies "Morphine 3 mg SQ every 4 hr. PRN for pain." This entry provides a clear dosage of morphine along with a specified route (subcutaneously), a frequency of administration (every 4 hours), and a "PRN" indication, which means it should be administered as needed for pain. This is crucial in a clinical setting to ensure that the medication is administered safely and effectively based on patient needs.

Telephonic prescriptions need to be clear and concise to avoid misunderstandings. The chosen entry meets these criteria by specifying both the medication and its administration allowances, which is particularly important given the potential risks associated with opiate medications like morphine.

In addition, the option ensures that the dosing is appropriate for pain management while allowing flexibility according to the patient's pain, since morphine is often prescribed on a PRN basis, especially in unpredictable pain scenarios.
