Correct Answer is B
Explanation
Calculation
- Convert the Ordered Dose to Milligrams (mg)
conversion factor: 1 g = 1,000 mg.
Ordered Dose (mg) = 1.5 g x 1,000 mg/g
= 1,500 mg
- Calculate the Number of Tablets
Ordered Dose (D): 1,500 mg
Available Dose (H): 500 mg
Tablets = Ordered Dose (D) / Available Dose (H)
= 1,500 mg / 500 mg
= 3 tablets
Correct Answer is A
Explanation
Calculation using the Formula Method
Desired Dose (D): 250 mg
Dose on Hand (H): 500 mg
Quantity (Q): 2 mL
The formula method is:
Amount to Administer = (Desired (D) / Have (H)) x Quantity (Q)
= (250 mg / 500 mg) x 2 mL
= 0.5 x 2 mL
= 1 mL
