A nurse receives a verbal order for a client for digoxin. Which of the following entries should the nurse document in the client's medical record?

Safe medical documentation requires the use of standardized terminology and the avoidance of dangerous abbreviations to prevent medication errors. The Joint Commission maintains a "Do Not Use" list, which prohibits notations that are easily misinterpreted, such as trailing zeros or missing leading zeros. Rationale: A. This entry is incorrect because it uses the abbreviation "QD" for daily, which is on the prohibited list as it can be mistaken for "QID" (four times daily). Additionally, it fails to include the unit of measurement "mg" after the dosage, which is a critical safety component. Standardized documentation requires writing out the word "daily" and including full units to ensure there is no ambiguity in the medical record. B. This is the correct entry because it follows all safety protocols, including the use of a leading zero (0.25 mg) and writing out "daily" and "by mouth." It also correctly documents that it was a verbal order (VO) and identifies both the prescribing provider and the receiving nurse. This level of detail ensures the order is legally sound and minimizes the risk of a ten-fold dosing error or route confusion. C. This entry is unsafe because it lacks a leading zero (.25 mg), which could result in the patient receiving 25 mg instead of 0.25 mg if the decimal point is missed. Such a massive overdose of digoxin would likely be fatal due to its narrow therapeutic index and cardiac toxicity. Furthermore, it fails to document that the order was a verbal order, which is necessary for legal and clinical accountability. D. Similar to choice C, this entry is incorrect due to the omission of the leading zero before the decimal point (.25 mg). While it correctly uses "VO" and "daily," the lack of a leading zero is a high-risk charting error that directly violates patient safety standards. Proper notation must always place a zero before a decimal to highlight the fractional nature of the dose to all clinical staff.
