Final answer:
The complete documentation entry related to PRN medication administration includes the date and time, medication name and dose, administration route, injection site, reason for administration, and the administering nurse's signature.
Step-by-step explanation:
The question pertains to documentation of PRN medication administration. Among the options provided, the first entry is the most complete because it includes the date and time the medication was given, the medication's name, dosage, route of administration, location where the injection was given, the reason for administration (patient's pain level), and the administering nurse's signature. Using medications such as Morphine, Fentanyl, Oxycodone, and others requires very specific documentation due to their nature as controlled substances and their potential for serious side effects. PRN stands for 'pro re nata,' which in medical terminology means 'as needed.' This kind of medication is given when a patient specifically requires it, typically for symptoms like pain or nausea, rather than on a scheduled basis. Accurate documentation is critical to ensure patient safety and to maintain a record of the patient's care.
