1.Easy
500 mL? mL/h24 h

500 mL of fluid must be infused over 24 hours by pump. Find the rate R in mL/h.

500 mL24 h
R = mL/h
2.Easy
100 mL75 mL/ht = ? h

100 mL of fluid is infused by pump at 75 mL/h. How many hours t will the infusion take? Round to one decimal place.

100 mL75 mL/h
t = h
3.Medium
150 mLleft? mL/h2 h left

500 mL was ordered over 8 hours. After 6 hours you find that 150 mL is still in the bag, and the order must still finish on time. To what rate R in mL/h must the pump be reset?

500 mL / 8 hafter 6 h: 150 mL
R = mL/h
4.Medium
V = ?15 gtt/mL50 gtt/min2 h

A drip runs at 50 gtt/min through a set of 15 gtt/mL. How many millilitres V does the patient receive in 2 hours?

50 gtt/min15 gtt/mL2 h
V = mL
5.Hard
500 mg250 mL15 gtt/mL200 mg/h? gtt/min

500 mg of a drug is diluted in 250 mL and given by gravity through a set of 15 gtt/mL. The order is 200 mg per hour. Find the drip rate R in drops per minute.

500 mg/250 mL200 mg/h15 gtt/mL
R = gtt/min
6.Hard
220 mLleft? mL/h2 h left

1000 mL was ordered over 10 hours. After 8 hours you find that 220 mL is still in the bag, and the order must still finish on time. By what percentage Δ must the original pump rate be increased?

1000 mL / 10 hafter 8 h: 220 mL
Δ = %

Answer key

  1. 1. R = 20.83 mL/h
  2. 2. t = 1.3 h
  3. 3. R = 75 mL/h
  4. 4. V = 400 mL
  5. 5. R = 25 gtt/min
  6. 6. Δ = 10 %
