A teenage client weighs 102 lbs. Calculate the weight in kilogram (to the nearest tenth):

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 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

Correct Answer is A

Explanation

Given:

Volume of fluid: 2500 mL

Infusion time: 8 hours

Drop factor: 15 gtt/mL

Formula:

Flow rate (gtt/min) = (Volume (mL) / Time (hr)) x Drop factor (gtt/mL) / 60 min/hr

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

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

Infusion rate (mL/hr) = 2500 mL / 8 hr

Infusion rate (mL/hr) = 312.5 mL/hr

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

Flow rate (gtt/min) = (Infusion rate (mL/hr) x Drop factor (gtt/mL)) / 60 min/hr

Flow rate (gtt/min) = (312.5 mL/hr x 15 gtt/mL) / 60 min/hr

Flow rate (gtt/min) = 4687.5 gtt/hr / 60 min/hr

Flow rate (gtt/min) = 78.125 gtt/min

Step 3: Round to the nearest whole number:

Flow rate (gtt/min) ≈ 78 gtt/min
