Review the rules in the Book of Style for transcribing a zero trailing a decimal point and a zero leading a decimal point. Assuming a zero is not dictated, which of the following are transcribed correctly?
potassium 3.0
chloride 103.0
glucose 250.0
creatinine 0.9
calcium 9.30
free T4 .8
Metaglip 2.5/250.0 mg
chloride 103
glucose 250
calcium 9.3
free T4 0.8
Metaglip 2.5/250 mg
Note: Potassium should be transcribed with the trailing zero to indicate the preciseness of the value. Since potassium has such a narrow normal range, the decimal is significant and is almost always dictated. This may not be obvious to the student and they may list potassium as transcribed incorrectly.
