Sample Nursing Dosage Calculation Practice Problems with Answers
Providing learners with practical problems enhances understanding. Here are several sample problems with detailed solutions:
Problem 1: Basic Tablet Calculation
Question:
A doctor orders 500 mg of amoxicillin. The medication available is in tablets of 250 mg each. How many tablets should be administered?
Solution:
- Total dose needed = 500 mg
- Strength per tablet = 250 mg
Number of tablets = Total dose / Strength per tablet
= 500 mg / 250 mg = 2 tablets
Answer:
Administer 2 tablets of amoxicillin.
---
Problem 2: IV Drip Rate Calculation
Question:
A patient requires 1000 mL of IV fluid over 8 hours. What should be the flow rate in mL/hour?
Solution:
Flow rate = Total volume / Time in hours
= 1000 mL / 8 hours = 125 mL/hour
Answer:
Set the IV infusion to deliver 125 mL/hour.
---
Problem 3: Medication Dose Based on Weight
Question:
The order is for 5 mg/kg of morphine sulfate. The patient weighs 70 kg. How much medication should be administered?
Solution:
Total dose = Dose per kg × Patient weight
= 5 mg/kg × 70 kg = 350 mg
Answer:
Administer 350 mg of morphine sulfate.
---
Problem 4: Unit Conversion and Calculation
Question:
A medication label states that 1 mL contains 50 mg of medication. The doctor orders 200 mg. How many mL should be administered?
Solution:
Volume to administer = Dose required / Concentration per mL
= 200 mg / 50 mg/mL = 4 mL
Answer:
Administer 4 mL of the medication.
---
Problem 5: Complex Calculation Using Dimensional Analysis
Question:
A nurse needs to prepare 100 mL of a medication solution. The medication's strength is 250 mg in 5 mL. The order is for 100 mg. How much of the medication should be added to 100 mL of diluent?
Solution:
Step 1: Find the concentration
= 250 mg / 5 mL = 50 mg/mL
Step 2: Calculate volume needed for 100 mg
= 100 mg / 50 mg/mL = 2 mL
Answer:
Add 2 mL of the medication to 100 mL of diluent.
