Common Pharmaceutical Calculations Questions and Sample Answers
Sample Question 1: Converting Units
Question: How many milligrams are in 2.5 grams?
Answer:
Since 1 gram = 1000 milligrams,
2.5 grams = 2.5 × 1000 = 2500 milligrams
Sample Question 2: Dosage Calculation
Question: A doctor prescribes 500 mg of amoxicillin to a patient. If the available suspension has a concentration of 250 mg/5 mL, how many milliliters should the patient take?
Answer:
Dose needed = 500 mg
Concentration = 250 mg / 5 mL
Calculate volume:
Volume = (Dose / Concentration) = (500 mg) / (250 mg / 5 mL)
= 500 mg × (5 mL / 250 mg)
= (500 × 5) / 250 = 2500 / 250 = 10 mL
The patient should take 10 mL.
Sample Question 3: Percentage Solution
Question: How to prepare 100 mL of a 10% w/v sodium chloride solution?
Answer:
A 10% w/v solution means 10 g of NaCl per 100 mL.
Therefore, weigh 10 g of NaCl and dissolve in distilled water to make up to 100 mL.
