A charge nurse is verifying a client's prescription which another nurse transcribed from a telephone order. Which of the following orders should the nurse recognize as including unaccepted abbreviations when documenting care?

The correct answer is B: Dx pyelonephritis. This abbreviation is not an accepted medical abbreviation and may lead to confusion or misinterpretation. "Dx" typically stands for diagnosis, not a medication or treatment. A: Ciprofloxacin 200 mg IV q12h x 7 days is clear and follows standard medication order format. C: Hourly 180 lacks context and clarity, making it an unacceptable abbreviation. D: Acetaminophen 1000 mg PO QD is also clear and follows standard medication order format. By eliminating unaccepted abbreviations, nurses ensure accurate communication and safe patient care.
