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 D
Explanation
A. 2.5 kg = 1 lb: This conversion overestimates the weight in kilograms. One pound is actually equal to approximately 0.454 kg.
B. 2.5 lb = 1 kg: This incorrectly suggests that 1 kilogram equals 2.5 pounds, which underestimates the weight in pounds. The accurate conversion requires 1 kg ≈ 2.2 lb.
C. 2.2 kg = 1 lb: This incorrectly reverses the relationship. One pound is approximately 0.454 kg, not 2.2 kg.
D. 2.2 lb = 1 kg: This is the correct conversion factor. One kilogram equals approximately 2.2 pounds, which the nurse can use to convert 80 lb to kilograms safely.
Correct Answer is B
Explanation
- Calculate the dose (number of tablets):
Ordered Dose (D) = 25 mg
Available Dose (H) = 50 mg per tablet
Tablets = (Ordered Dose / Available Dose)
= (25 mg / 50 mg)
= 0.5 tablet (or 1/2 tablet)
