Q1A physician orders 500 mL of lactated Ringer's solution to infuse over 4 hours. What is the correct infusion rate in mL/hr?
Show answer
✓ Correct answer: 125 mL/hr
To calculate mL/hr, divide the total volume by the time in hours: 500 mL divided by 4 hours = 125 mL/hr.
Q2An order reads: Infuse 1500 mL D5W over 12 hours using tubing with a drop factor of 10 gtt/mL. What is the correct drip rate in drops per minute?
Show answer
✓ Correct answer: 21 gtt/min
Using the formula (Volume × Drop factor) divided by Time in minutes: (1500 × 10) divided by 720 minutes = 15000 divided by 720 = 20.8, which rounds to 21 gtt/min.
Q3A patient weighing 70 kg requires dopamine at 5 mcg/kg/min. The solution concentration is 400 mg in 250 mL. What infusion rate in mL/hr should be set?
Show answer
✓ Correct answer: 13.1 mL/hr
First calculate the dose: 70 kg × 5 mcg/kg/min = 350 mcg/min. Convert to mg/min: 350 mcg divided by 1000 = 0.35 mg/min. Convert to mg/hr: 0.35 × 60 = 21 mg/hr. Calculate concentration: 400 mg in 250 mL = 1.6 mg/mL. Finally: 21 mg/hr divided by 1.6 mg/mL = 13.125 mL/hr, rounds to 13.1 mL/hr.
Q4A medication order specifies 250 mg in 100 mL to infuse over 30 minutes. What is the infusion rate in mL/hr?
Show answer
✓ Correct answer: 200 mL/hr
To convert 30 minutes to an hourly rate: 100 mL in 30 minutes equals 100 mL divided by 0.5 hours = 200 mL/hr. Alternatively, 100 mL × 2 (since 30 min is half an hour) = 200 mL/hr.
Q5An IV is infusing at 125 mL/hr. Using tubing with a drop factor of 20 gtt/mL, what is the drip rate in drops per minute?
Show answer
✓ Correct answer: 42 gtt/min
Convert mL/hr to mL/min first: 125 mL/hr divided by 60 min = 2.083 mL/min. Then multiply by drop factor: 2.083 × 20 = 41.66, which rounds to 42 gtt/min. Alternatively, use the formula: (mL/hr × Drop factor) divided by 60 = (125 × 20) divided by 60 = 41.66, rounds to 42 gtt/min.
Q6A vial contains 1 gram of medication powder. The reconstitution instructions state to add 9.6 mL of sterile water to yield 10 mL of solution. What is the final concentration in mg/mL?
Show answer
✓ Correct answer: 100 mg/mL
Convert 1 gram to milligrams: 1 g = 1000 mg. The final volume is 10 mL. Concentration = 1000 mg divided by 10 mL = 100 mg/mL.
