Deck 18: Iv Flow Rate Calculation

Question 1

An IV infusion of 500 mL to infuse over 8 hours was started at 10 am. At 12:30 pm, there is 300 mL remaining. Recalculate the rate (to the nearest whole number) to complete the infusion on time using a 15 gtt/mL set.

Answer 1

14 gtt/min
8 hr - 2.5 hr = 5.5 hr
300 mL ÷ 5.5 hr = 54.5 mL/hr
54.5 mL/hr ÷ 60 min/hr = 0.9 mL/min

Question 2

An infusion of 230 mL was ordered to infuse in 48 minutes. After 15 minutes the volume remaining is 160 mL. Calculate the new flow rate (to the nearest whole number) to complete the infusion on time. The set delivers 15 gtt/mL.

Answer 2

72-73 gtt/min
48 min - 15 min = 33 min
160 mL ÷ 33 min = 4.84 = 4.8 mL/min

Question 3

Infuse 43 mL in 8 minutes using 20 gtt/mL set. Calculate the gtt/min to the nearest whole number.

Answer 3

108 gtt/min
43 mL ÷ 8 min = 5.37 = 5.4 mL/min

Question 4

The order is to infuse 1300 mL in 8 hours using a 20 gtt/mL set. Calculate the gtt/min to the nearest whole number.

Question 5

The order is for 3300 mL to infuse in 17 hours using a 10 gtt/mL set. Calculate the gtt/min to the nearest whole number.

Question 6

The order is to infuse 94 mL in 20 minutes using a 60 gtt/mL set. Calculate the gtt/min to the nearest whole number.

Question 7

The order is to infuse 800 mL over 3.5 hours beginning at 9 pm. At 10:30 pm, the IV has infiltrated with 525 mL remaining in the bag. The IV was restarted at 11 pm. Calculate the flow rate (to the nearest whole number) using a 10 gtt/mL set to complete the infusion on time.

Question 8

Administer 470 mL in 3 hours using a 10 gtt/mL set. Calculate the gtt/min to the nearest whole number.

Question 9

Set calibration is 20 gtt/mL. Administer 72 mL in 53 minutes. Calculate the gtt/min to the nearest whole number.

Question 10

An IV of 750 mL was to infuse in 4 hours. After 1 hour, 300 mL has infused. Recalculate the gtt/min rate to complete the infusion on time (to the nearest whole number). A 15 gtt/mL set is being used.

Question 11

Administer 125 mL in 45 minutes using a microdrip set. Calculate the gtt/min to the nearest whole number.

Question 12

The available set is calibrated to 15 gtt/mL. Calculate the flow rate (to the nearest whole number) for an infusion of 360 mL in 1.5 hours.

Question 13

A patient is to receive 14 mL in 12 minutes using a microdrip set. Calculate the gtt/min to the nearest whole number.

Question 14

Calculate the flow rate (to the nearest whole number) for an infusion of 2750 mL in 18 hours using a 10 gtt/mL set.

Question 15

Infuse 50 mL in 15 minutes using a 10 gtt/mL set. Calculate the gtt/min to the nearest whole number.

Question 16

A volume of 360 mL is to infuse in 2 hours using a 15 gtt/mL set. At the end of 45 minutes, you discover that 225 mL remains. Should the flow rate be adjusted? If so, what is the correct rate to complete the infusion on time?

Question 17

Administer 36 mL in 14 minutes using a microdrip set. Calculate the gtt/min to the nearest whole number.

Question 18

Infuse 75 mL over 23 minutes using a 20 gtt/mL set. Calculate the gtt/min to the nearest whole number.

Question 19

Infuse 7 mL in 5 minutes using a microdrip set. Calculate the gtt/min to the nearest whole number.

Question 20

Calculate the rate (to the nearest whole number) for an infusion of 2300 mL to run over 20 hours using a 10 gtt/mL set.

Question 21

Using a 60 gtt/mL set, administer 17 mL over 21 minutes. Calculate the gtt/min to the nearest whole number.

Question 22

The available set is calibrated to 20 gtt/mL. The ordered infusion is 1250 mL in 19 hours. Calculate the gtt/min to the nearest whole number.

Question 23

The ordered infusion is 1900 mL in 24 hours using a 15 gtt/mL set. After 11 hours, 800 mL remains. Calculate the rate (to the nearest whole number) to complete the infusion on time.

Question 24

A volume of 2100 mL is to infuse over 18 hours. Calculate the flow rate (to the nearest whole number) using a 20 gtt/mL set.

Question 25

The order reads: "Infuse 90 mL in 1 hour." The set is calibrated to 10 gtt/mL. Calculate the gtt/min to the nearest whole number.
