A medication is prescribed at 75 mg, and it is available as 150 mg per tablet. Using the desired over have method, how many tablets should be administered?
2 tablets
0.5 tablets
1.5 tablets
1 tablet
The Correct Answer is B
Calculation:
- Identify the desired dose and the available dose
Desired Dose: 75 mg
Available Dose: 150 mg per tablet
- Apply the Desired ÷ Have method
Number of Tablets = Desired ÷ Have
Number of Tablets = 75 ÷ 150
Number of Tablets = 0.5 tablets

Correct Answer is C
Explanation
A. 1 mg = 100 mcg: One milligram equals 1,000 micrograms, not 100. Using 100 would underestimate the dose by tenfold, potentially leading to medication errors.
B. 1 mcg = 1,000 mg: One microgram is much smaller than a milligram; 1 mcg equals 0.001 mg. This option greatly overstates the amount, which could result in dangerous dosing errors.
C. 1 mg = 1,000 mcg: One milligram is equal to 1,000 micrograms. This is the correct conversion and is essential for accurate medication calculations, particularly for drugs that require very small doses.
D. 1 mcg = 100 mg: One microgram is far smaller than a milligram; this option reverses the relationship and exaggerates the amount, which is unsafe for clinical dosing.
Correct Answer is D
Explanation
Calculation:
- Available Concentration: 50 mg/mL
Ordered Dose: 125 mg
- Calculate the volume to administer
Volume to administer = Ordered Dose ÷ Concentration
Volume to administer = 125 ÷ 50
Volume to administer = 2.5 mL
