Tagamet 300 mg IVPB q8hr. The medication has been added to 50 mL DSW to infuse over 30 minutes. How many ml/hr?

A.

125 mL/hr

B.

6 mL/hr

C.

100 mL/hr

D.

38 mL/hr

Answer and Explanation

The Correct Answer is C

Given:
Volume of fluid: 50 mL (DSW)
Infusion time: 30 minutes

Formula:
Flow rate (mL/hr) = Volume (mL) / Time (hr)

Step 1: Convert infusion time to hours:
Infusion time (hr) = 30 min / 60 min/hr
Infusion time (hr) = 0.5 hr

Step 2: Calculate the infusion rate in mL/hr:
Flow rate (mL/hr) = Volume (mL) / Infusion time (hr)
Flow rate (mL/hr) = 50 mL / 0.5 hr
Flow rate (mL/hr) = 100 mL/hr

Correct Answer is D

Explanation

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: 30 mL
Infusion time: 20 minutes

Step 1: Convert infusion time to hours:
Infusion time (hr) = 20 min / 60 min/hr
Infusion time (hr) = 0.33 hr

Step 2: Calculate the infusion rate in mL/hr:
Flow rate (mL/hr) = Volume (mL) / Infusion time (hr)
Flow rate (mL/hr) = 30 mL / 0.33 hr
Flow rate (mL/hr) = 90.90909091 mL/hr

Step 3: Round to the nearest whole number:
Flow rate (mL/hr) ≈ 90 mL/hr
