A charge nurse is evaluating a newly licensed nurse's electronic documentation for several clients. Which of the following entries for medication doses should the charge nurse identify as correct?

Rationale: A. 300 mg PO od: The dose is written clearly with no trailing zeros, and “od” (once daily) is acceptable though “daily” is preferred for clarity. This entry minimizes risk of misinterpretation and decimal errors. B. 3.0 mg PO gd: Using a trailing zero (3.0 mg) increases the risk of a tenfold dosing error if the decimal point is missed. Also, “gd” is an incorrect abbreviation; “daily” or “once daily” should be used. C. 10.000 units IV dally: Writing “10.000” with multiple trailing zeros is dangerous because the decimal point might be overlooked, causing a ten-thousand-fold error. Also, “dally” is a misspelling of “daily.” D. 05 mL IM daily: Leading zeros before whole numbers (05 mL) are unnecessary and can cause confusion. The correct notation is “5 mL.” Leading zeros should only be used before decimals less than one (e.g., 0.5 mL).
