A physician prescribes a medication dosage of 0.25 grams. What is this dosage in milligrams?
A. 750 milligrams
Calculation: Given: Ordered Dose = 0.25 g Conversion: 1 g = 1000 mg Dose in mg = Ordered Dose × 1000 = 0.25 × 1000 = 250 mg
B. 250 milligrams
Calculation: Given: Ordered Dose = 0.25 g Conversion: 1 g = 1000 mg Dose in mg = Ordered Dose × 1000 = 0.25 × 1000 = 250 mg
C. 25 milligrams
Calculation: Given: Ordered Dose = 0.25 g Conversion: 1 g = 1000 mg Dose in mg = Ordered Dose × 1000 = 0.25 × 1000 = 250 mg
D. 2500 milligrams
Calculation: Given: Ordered Dose = 0.25 g Conversion: 1 g = 1000 mg Dose in mg = Ordered Dose × 1000 = 0.25 × 1000 = 250 mg

Full Explanation
Calculation:
Given:
Ordered Dose = 0.25 g
Conversion: 1 g = 1000 mg
Dose in mg = Ordered Dose × 1000
= 0.25 × 1000
= 250 mg

The prescription requires 2.4 g of a medication available in 600 mg tablets. Using ratio and proportion, determine the number of tablets.
A. 4 tablets
Calculation: Ordered Dose = 2.4 g Available Dose = 600 mg Convert Ordered Dose to mg Ordered Dose = 2.4 × 1000 = 2400 mg Number of tablets = Ordered Dose / Available Dose = 2400 / 600 = 4 tablets
B. 5 tablets
Calculation: Ordered Dose = 2.4 g Available Dose = 600 mg Convert Ordered Dose to mg Ordered Dose = 2.4 × 1000 = 2400 mg Number of tablets = Ordered Dose / Available Dose = 2400 / 600 = 4 tablets
C. 3 tablets
Calculation: Ordered Dose = 2.4 g Available Dose = 600 mg Convert Ordered Dose to mg Ordered Dose = 2.4 × 1000 = 2400 mg Number of tablets = Ordered Dose / Available Dose = 2400 / 600 = 4 tablets
D. 6 tablets
Calculation: Ordered Dose = 2.4 g Available Dose = 600 mg Convert Ordered Dose to mg Ordered Dose = 2.4 × 1000 = 2400 mg Number of tablets = Ordered Dose / Available Dose = 2400 / 600 = 4 tablets
Full Explanation
Calculation:
Ordered Dose = 2.4 g
Available Dose = 600 mg
- Convert Ordered Dose to mg
Ordered Dose = 2.4 × 1000
= 2400 mg
Number of tablets = Ordered Dose / Available Dose
= 2400 / 600
= 4 tablets
How does the lot number on a drug label contribute to drug safety?
