A nurse is transcribing a telephone prescription for acetaminophen 650 mg by mouth daily at bedtime. The nurse should identify that which of the following abbreviations are acceptable to use when transcribing the prescription?

A. Abbreviate "daily" as "QD": The abbreviation "QD" is no longer recommended because it can be confused with "QID" (four times daily), potentially leading to dangerous medication errors. B. Abbreviate "by mouth" as "PO": "PO" is the standard and accepted abbreviation for "by mouth," and it is widely used in medical documentation without ambiguity. C. Abbreviate "acetaminophen" as "APAP": "APAP" is not universally recognized and may lead to confusion. Using the full name of the drug "acetaminophen" is safer and clearer. D. Abbreviate "at bedtime" as "qhs": "Qhs" is discouraged as it can be easily misinterpreted. Writing "at bedtime" without abbreviations is the recommended practice to avoid errors.
