How many minutes are in TWO hours?

A. 6/10 mg.: Writing 6/10 mg is not an accepted or safe dosage notation because it increases the risk of misinterpretation and medication error. Dosages should always be written using decimals rather than fractions to ensure clarity and accuracy in administration.

B. 0.60 mg.: Although this value is numerically equivalent to 0.6 mg, it is unsafe to include a trailing zero after the decimal point. The extra zero could be misread as 60 mg, leading to a dangerous overdose. Standard medication safety guidelines prohibit the use of trailing zeros.

C. 0.6 mg.: This is the correctly written dosage because it uses a leading zero before the decimal point and omits any trailing zeros. This format minimizes the risk of dosage errors and aligns with safe medication administration practices endorsed by The Joint Commission.

D. 6 mg.: This dose would be excessively high for nitroglycerin, as therapeutic oral doses typically range between 0.3 to 0.6 mg. Administering 6 mg could cause severe hypotension, dizziness, or syncope due to excessive vasodilation.

Nursing students are not permitted to administer medications that they did not personally prepare or verify. Medication safety protocols require that the individual who prepares the medication also administers it to ensure accuracy, accountability, and prevent medication errors.
