Calculate the rate in gtt/min for the following medications being administered IVPB.

Order: Doxycycline 25 mg IVPB D5W 50 mL over 1 hr. Drop factor: 15 gtt/mL

A.

6 gtt/min

B.

20 gtt/min

C.

25 gtt/min

D.

13 gtt/min

Answer and Explanation

The Correct Answer is D

Given:

Volume of fluid: 50 mL

Infusion time: 1 hour (60 minutes)

Drop factor: 15 gtt/mL

 

Formula:

Flow rate (gtt/min) = (Volume (mL) / Time (min)) x Drop factor (gtt/mL)

 

Step 1: Calculate the infusion rate in mL/min:

Infusion rate (mL/min) = Volume (mL) / Time (min)

Infusion rate (mL/min) = 50 mL / 60 min

Infusion rate (mL/min) = 0.83 mL/min

 

Step 2: Calculate the flow rate in gtt/min:

Flow rate (gtt/min) = Infusion rate (mL/min) x Drop factor (gtt/mL)

Flow rate (gtt/min) = 0.83 mL/min x 15 gtt/mL

Flow rate (gtt/min) = 12.5 gtt/min

 

Step 3: Round to the nearest whole number:

Flow rate (gtt/min) ≈ 13 gtt/min

Correct Answer is B

Explanation

Given:

Volume of fluid: 100 mL

Infusion time: 1 hour (60 minutes)

Drop factor: 10 gtt/mL

Formula:

Flow rate (gtt/min) = (Volume (mL) / Time (min)) x Drop factor (gtt/mL)

Step 1: Calculate the infusion rate in mL/min:

Infusion rate (mL/min) = Volume (mL) / Time (min)

Infusion rate (mL/min) = 100 mL / 60 min

Infusion rate (mL/min) = 1.67 mL/min

Step 2: Calculate the flow rate in gtt/min:

Flow rate (gtt/min) = Infusion rate (mL/min) x Drop factor (gtt/mL)

Flow rate (gtt/min) = 1.67 mL/min x 10 gtt/mL

Flow rate (gtt/min) = 16.7 gtt/min

Step 3: Round to the nearest whole number:

Flow rate (gtt/min) ≈ 17 gtt/min

Correct Answer is D

Explanation

Given:

Volume of Glucerna 1.2: 237 mL

Desired concentration: 1/2 strength

Step 1: Determine the volume of Glucerna 1.2 needed for the half-strength solution:

Volume of Glucerna 1.2 for half-strength = Original volume / 2

Volume of Glucerna 1.2 for half-strength = 237 mL / 2

Volume of Glucerna 1.2 for half-strength = 118.5 mL

Step 2: Calculate the amount of water to be added:

Amount of water = Original volume - Volume of Glucerna 1.2 for half-strength

Amount of water = 237 mL - 118.5 mL

Amount of water = 118.5 mL
