A nurse is receiving a telephone prescription from a provider for a client who requires additional medication for pain control. Which of the following entries should the nurse make in the medical record?

A. "Morphine 3.0 mg sub q every 4 hr PRN for pain." Including a trailing zero (3.0 mg) is considered unsafe and is discouraged in medication documentation. It increases the risk of a tenfold overdose if the decimal is missed. B. "Morphine 3 mg subcutaneous every 4 hr PRN for pain." This entry uses the correct dosage format without a trailing zero, the full term "subcutaneous" instead of abbreviations, and proper medical terminology. It adheres to safe documentation practices as per The Joint Commission guidelines. C. "Morphine 3 mg SC q 4 hr PRN for pain." The abbreviation “SC” is considered unsafe and prone to misinterpretation. Also, "q" for "every" is discouraged in clinical documentation due to potential misreading and error. D. "Morphine 3 mg SQ every 4 hr PRN for pain." The abbreviation “SQ” can be misinterpreted or mistaken for “5 every” or other terms. Safe practice requires spelling out “subcutaneous” to prevent errors in medication administration.
