Final answer:
The abbreviations 'QD' (daily) and 'NPO' (nothing per os) are on the list of the Joint Commission do not use abbreviations.
Step-by-step explanation:
The abbreviation 'QD' (daily) is on the list of the Joint Commission do not use abbreviations. This abbreviation is considered confusing and can be misinterpreted as 'qid' (four times a day) which can result in medication errors.
The abbreviation 'NPO' (nothing per os) is also on the list. This abbreviation is ambiguous and can be misinterpreted as 'NP' (nasal prongs), 'NO' (nitric oxide), or 'NO' (nitrous oxide) which can lead to patient harm or medication errors.
