A.

46.36 Kg

B.

46.4 Kg

C.

46 Kg

D.

4.64 Kg

Answer and Explanation

The Correct Answer is B

Given:

Weight in pounds: 102 lbs

Conversion factor: 1 lb = 0.453592 kg

 

Step 1: Convert pounds to kilograms:

Weight in kg = Weight in lbs x Conversion factor (kg/lb)

Weight in kg = 102 lbs x 0.453592 kg/lb

Weight in kg = 46.266544 kg

 

Step 2: Round to the nearest tenth:

Weight in kg ≈ 46.3 kg

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: 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
