A. DAW 1
B. DAW 2

A 5 mL bottle of eye drops delivers 20 drops per mL. The sig is '1 drop in each eye twice daily.' What is the days' supply?
A. 12 days
B. 25 days
C. 50 days
D. 100 days
Show answer and reasoning
Correct answer: B. 25 days
5 mL × 20 drops/mL = 100 drops. One drop in each eye twice daily is 4 drops per day. 100 ÷ 4 = 25 days.
- A: 12 days would result from assuming the dose is 2 drops in each eye twice daily.
- C: 50 days would be correct only if the drops were used in one eye.
- D: 100 days assumes one drop per day total.

A child weighs 44 pounds. The prescriber orders cefdinir at 10 mg/kg per dose. The suspension on hand is 100 mg per 5 mL. How many milliliters are given per dose?
A. 5 mL
B. 10 mL
C. 20 mL
D. 22 mL
Show answer and reasoning
Correct answer: B. 10 mL
44 lb ÷ 2.2 = 20 kg. 20 kg × 10 mg/kg = 200 mg per dose. At 100 mg/5 mL, 200 mg is 10 mL.
- A: 5 mL would deliver 100 mg, only half the calculated dose.
- C: 20 mL would deliver 400 mg, double the dose.
- D: 22 mL results from using the weight in pounds instead of converting to kilograms.

A. 33 mg
B. 50 mg
C. 75 mg
D. 150 mg
Show answer and reasoning
Correct answer: C. 75 mg
Dose = 50 mg/m² × 1.5 m² = 75 mg.
- A: 33 mg results from dividing 50 by 1.5 instead of multiplying.
- B: This is the per-square-meter dose, not the patient's dose.
- D: 150 mg would be the dose for a body surface area of 3 m².
