Unit Conversion Question: Convert 2 liters (L) to milliliters (mL). Answer: 1 L = 1000 mL, so 2 L = 2000 mL

1. Unit Conversion Question: Convert 3.5 grams (g) to milligrams (mg). Answer: 1 g = 1000 mg, so 3.5 g = 3500 mg

2. Dosage Calculation Question: The doctor ordered 75 mg of medication. The available medication is in 25 mg tablets. How many tablets should the patient take? Answer: 75 mg ÷ 25 mg/tablet = 3 tablets

3. Dosage Calculation Question: A prescription states "Amoxicillin 250 mg, dispense 30 tablets." How many total milligrams of Amoxicillin are in the prescription? Answer: 250 mg/tablet × 30 tablets = 7500 mg

4. IV Flow Rate Calculation Question: Calculate the IV flow rate for 1500 mL of fluid to be infused over 6 hours. Use a drop factor of 15 drops/mL. Answer: (1500 mL × 15 drops/mL) ÷ (6 hours × 60 minutes/hour) = 62.5 gtts/min (rounded to 63 gtts/min)

5. IV Flow Rate Calculation Question: Calculate the IV flow rate for 2000 mL of fluid to be infused over 4 hours. Use a drop factor of 10 drops/mL. Answer: (2000 mL × 10 drops/mL) ÷ (4 hours × 60 minutes/hour) = 83.33 gtts/min (rounded to 83 gtts/min)

6. Pediatric Dosage Calculation Question: A pediatric patient weighs 18 kg. The prescribed medication dose is 10 mg/kg/day, divided into two equal doses. How many milligrams should each dose contain? Answer: (18 kg × 10 mg/kg) ÷ 2 doses/day = 90 mg/dose

7. Pediatric Dosage Calculation Question: A pediatric patient weighs 12 kg. The prescribed medication dose is 8 mg/kg/day, divided into four equal doses. How many milligrams should each dose contain? Answer: (12 kg × 8 mg/kg) ÷ 4 doses/day = 24 mg/dose

8. Body Surface Area (BSA) Calculation Question: Calculate the BSA of a patient weighing 70 kg and measuring 175 cm tall using the Mosteller formula. Answer: BSA = √(70 kg × 175 cm ÷ 3600) = 1.84 m²

9. BSA-based Dosage Calculation Question: A patient has a BSA of 1.6 m². The prescribed medication dose is 250 mg/m². How many milligrams should the patient receive? Answer: 1.6 m² × 250 mg/m² = 400 mg

10. Dilution Calculation Question: You have 50 mg of medication in a 10 mL vial. What is the concentration of the medication in mg/mL? Answer: 50 mg ÷ 10 mL = 5 mg/mL

11. Dilution Calculation Question: You need to prepare 500 mL of a 0.9% NaCl solution. How many grams of NaCl are required? Answer: 500 mL × 0.9 g/100 mL = 4.5 g

12. Infusion Time Calculation (continued) Question: An IV infusion has 1250 mL of fluid to be administered at a rate of 50 mL/hour. How long will the infusion take to complete? Answer: 1250 mL ÷ 50 mL/hour = 25 hours

13. Infusion Time Calculation Question: An IV infusion has 800 mL of fluid to be administered at a rate of 100 mL/hour. How long will the infusion take to complete? Answer: 800 mL ÷ 100 mL/hour = 8 hours

14. Weight-based Dosage Calculation Question: An adult patient weighs 80 kg. The prescribed medication dose is 20 mg/kg. How many milligrams should the patient receive? Answer: 80 kg × 20 mg/kg = 1600 mg

15. Weight-based Dosage Calculation Question: An adult patient weighs 65 kg. The prescribed medication dose is 5 mg/kg. How many milligrams should the patient receive? Answer: 65 kg × 5 mg/kg = 325 mg

16. Insulin Calculation Question: A patient's blood sugar level is 250 mg/dL, and their insulin sensitivity factor is 50. The patient's target blood sugar level is 100 mg/dL. How many units of insulin should the patient receive? Answer: (250 mg/dL - 100 mg/dL) ÷ 50 = 3 units of insulin

17. Insulin Calculation Question: A patient's blood sugar level is 320 mg/dL, and their insulin sensitivity factor is 40. The patient's target blood sugar level is 120 mg/dL. How many units of insulin should the patient receive? Answer: (320 mg/dL - 120 mg/dL) ÷ 40 = 5 units of insulin

18. Oxygen Flow Rate Calculation Question: A patient requires an oxygen flow rate of 3 L/min. How many minutes will a 1500 L oxygen cylinder last? Answer: 1500 L ÷ 3 L/min = 500 minutes

19. Oxygen Flow Rate Calculation Question: A patient requires an oxygen flow rate of 4 L/min. How many minutes will a 2000 L oxygen cylinder last? Answer: 2000 L ÷ 4 L/min = 500 minutes
