2. Calculate the flow rate in gtt/min. (Simplify your answer completely. Express your answer to the nearest whole number.)

An IV of 1,000 mL was ordered to run in 6 hr. After 3 hr, only 350 mL have infused. The set calibration is 20 gtt/mL. Recalculate the rate for the remaining solution to complete on time.

3.Calculate the flow rate in gtt/min. (Simplify your answer completely. Express your answer to the nearest whole number.)

Administer 16 mL in 38 min using a microdrip set.

4. Calculate the flow rate in gtt/min. (Simplify your answer completely. Express your answer to the nearest whole number.)

Infuse 1 liter in 9 hr using a set calibration of 15 gtt/mL.

Answer 1

1) Calculate the flow rate(gtt/min).

Flow rate(gtt/min) = Volume(ml)/Time(min) * Drop factor(gtt/ml).

Here

Volume(ml) = 1700 ml.

Time(min) = 480 min (8 hr, 8 * 60 min)

Drop factor(gtt/ml) = 20 gtt/ml.

As per above formula

Flow rate(gtt/min) = 1700/480 * 20

= 3.54 * 20

= 70.8

= 71 gtt/min.

2) Calculation of flow rate(gtt/min) .

Flow rate(gtt/min) = Volume(ml) / Time(min) * Drop factor(gtt/ml).

Here

Remaining Volume(ml) = 1000 - 350

= 650 ml.

Remaining Time(min) = 6 hr - 3 hr

= 3 hr.

= 3 * 60 min

= 180 min.

Drop factor(gtt/ml) = 20 gtt/ml.

As per above formula

Flow rate(gtt/min) = 650/180 * 20

= 3.61 * 20

= 72.2

= 72 gtt/min.

3) Calculation of flow rate(gtt/min).

Flow rate(gtt/min) = Volume(ml)/Time(min) * Drop factor(gtt/ml).

Here

Volume(ml) = 16 ml.

Time(min) = 38 min.

Drop factor(gtt/ml) = 60 ( drop factor of a microdrip is 60 gtt/ml).

As per above formula

Flow rate(gtt/min) = 16/38 * 60

= 0.42 * 60

= 25.2

= 25 gtt/min.

4) Calculation of flow rate(gtt/min).

Flow rate(gtt/min) = Volume(ml) / Time(min) * Drop factor(gtt/ml).

Here

Volume(ml) = 1000 ml (1 liter).

Time(min) = 540 min ( 9 hr, 9 * 60 min).

Drop factor(gtt/ml) = 15 gtt/ml.

As per above formula

Flow rate(gtt/min) = 1000/540 * 15

= 1.85 * 15

= 27.7

= 28 gtt/min.
