The medication order is for 325 mg of an oral suspension twice daily. The nurse correctly indicates that _________grams is the equivalent measurement.
325.0
0.325
32.5
3.25
The Correct Answer is B
Calculation:
Given dose = 325 mg
Conversion factor: 1 gram (g) = 1,000 milligrams (mg)
- Calculate the dose in grams (g).
Dose (g) = (Dose in mg / Conversion factor)
= (325 mg / 1,000 mg/g)
= 0.325 g.

Correct Answer is A
Explanation
A. mcg/15 mL: Writing the strength as “mcg/15 mL” is incomplete because it does not specify the actual amount of drug per 15 mL. This could lead to dosing errors, as the patient order must clearly indicate the exact micrograms per milliliter.
B. 1 mcg/1 mL: This correctly represents the concentration of the solution, clearly showing that each milliliter contains 1 microgram of calcitriol. It provides precise guidance for accurate dosing.
C. 1 mcg per 1 mL: This phrasing is clear and unambiguous, specifying the exact amount of drug in each milliliter. It is an acceptable way to document the dosage strength.
D. 1 mcg/Ml: Despite the lowercase “l” for milliliter, this notation still accurately communicates the concentration. While proper capitalization is preferred, it does not significantly risk misinterpretation.
Correct Answer is A
Explanation
Calculation:
- Convert the Ordered Dose from grams (g) to milligrams (mg).
Ordered Dose = 0.75 g
Conversion factor = 1 g = 1,000 mg
Ordered Dose (mg) = 0.75 g x 1,000 mg/g
= 750 mg
Dose Ordered (D) = 750 mg (the converted dose)
Dose Available (H) = 250 mg
Quantity (Q) = 5 mL
Volume (mL) = (Dose Ordered (D) / Dose Available (H)) x Quantity (Q)
= (750 mg / 250 mg) x 5 mL
= 3 x 5 mL
= 15 mL
