Preview Questions
Question 1
A patient weighs 176 lbs. What is their weight in kilograms?
Answer
80 kg. To convert pounds to kilograms, divide by 2.2 (176 ÷ 2.2 = 80 kg).
Question 2
A physician orders amoxicillin 40 mg/kg/day in 3 divided doses for a child weighing 22 lbs. What is the dose per administration?
Answer
133.3 mg per dose. Convert 22 lbs to 10 kg, multiply by 40 mg = 400 mg/day, then divide by 3 doses = 133.3 mg.
Question 3
A prescription reads: 'Give 1 tsp of amoxicillin 250 mg/5 mL three times daily for 10 days.' How many milliliters are needed to fill the entire course?
Answer
150 mL. One tsp = 5 mL × 3 doses/day × 10 days = 150 mL.
Question 4
A drug is available as 500 mg/tablet. The prescribed dose is 1.5 g. How many tablets should be dispensed per dose?
Answer
3 tablets. Convert 1.5 g to 1500 mg, then divide by 500 mg/tablet = 3 tablets.
Question 5
A physician orders 0.25 mg of digoxin. The available concentration is 0.5 mg/2 mL. How many mL should be administered?
Answer
1 mL. Using ratio-proportion: 0.5 mg/2 mL = 0.25 mg/X → X = 1 mL.
