1.Easy
1000 mL250 mL/ht = ? h

1000 mL of fluid is infused by pump at 250 mL/h. How many hours t will the infusion take?

1000 mL250 mL/h
t = h
2.Easy
100 mL80 mL/ht = ? h

100 mL of fluid is infused by pump at 80 mL/h. How many hours t will the infusion take? Round to one decimal place.

100 mL80 mL/h
t = h
3.Medium
60 gtt/mL40 mL/h? gtt/min

An infusion is ordered at 40 mL/h, but no pump is available. It runs by gravity through a giving set of 60 gtt/mL. Find the drip rate R in drops per minute.

40 mL/h60 gtt/mL
R = gtt/min
4.Medium
1500 mL10 gtt/mL8 h? gtt/min

Infuse 1500 mL over 8 hours with a giving set of 10 gtt/mL. Find the drip rate R in drops per minute. Round to the nearest whole number.

1500 mL8 h10 gtt/mL
R = gtt/min
5.Hard
1220 mLleft? mL/h8 h left

1500 mL was ordered over 12 hours. After 4 hours you find that 1220 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?

1500 mL / 12 hafter 4 h: 1220 mL
Δ = %
6.Hard
500 mg250 mL60 gtt/mL40 mg/h? gtt/min

500 mg of a drug is diluted in 250 mL and given by gravity through a set of 60 gtt/mL. The order is 40 mg per hour. Find the drip rate R in drops per minute.

500 mg/250 mL40 mg/h60 gtt/mL
R = gtt/min

Answer key

  1. 1. t = 4 h
  2. 2. t = 1.3 h
  3. 3. R = 40 gtt/min
  4. 4. R = 31 gtt/min
  5. 5. Δ = 22 %
  6. 6. R = 20 gtt/min
