A nurse is calculating the dosage of a medication prescribed as 0.75 g but supplied as 250 mg tablets. How many tablets should the nurse administer?
4 tablets
3 tablets
6 tablets
2 tablets
The Correct Answer is B
Calculation:
- Convert the prescribed dose to the same unit as the available tablets
Prescribed Dose: 0.75 g
= 750 mg
Available Tablet Strength: 250 mg per tablet
- Calculate the number of tablets to administer
Number of Tablets = Prescribed Dose ÷ Tablet Strength
Number of Tablets = 750 ÷ 250
Number of Tablets = 3 tablets

Correct Answer is B
Explanation
Calculation:
Ordered Dose: 0.25 mg
Available Tablet Strength: 0.125 mg
- Calculate the number of tablets
Number of Tablets = Dose ÷ Tablet Strength
Number of Tablets = 0.25 ÷ 0.125
Number of Tablets = 2 tablets
Correct Answer is D
Explanation
A. Right medication: The right medication focuses on ensuring the correct drug is selected and matched with the prescription. Confirming the patient’s meal schedule does not address whether the correct medication is being administered.
B. Right documentation: The right documentation involves accurately recording medication administration details after giving the drug. Meal timing relates to when the medication is given, not how it is recorded.
C. Right route: The right route ensures the medication is given via the correct pathway, such as oral or intravenous. Taking a medication with food affects timing and absorption, not the route of administration.
D. Right time: Confirming the patient’s meal schedule ensures the medication is given at the appropriate time in relation to food intake. This supports proper absorption, effectiveness, and reduction of adverse effects, making it a priority for the right time.
