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 A

Explanation

Given:

Volume of fluid: 50 mL (DSW) + 10 mL (for reconstitution) = 60 mL

Infusion time: 40 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) = 60 mL / 40 min

Infusion rate (mL/min) = 1.5 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) = 1.5 mL/min x 15 gtt/mL

Flow rate (gtt/min) = 22.5 gtt/min

Step 3: Round to the nearest whole number:

Flow rate (gtt/min) ≈ 23 gtt/min

Correct Answer is B

Explanation

Given:

Volume of fluid: 500 mL

Infusion time: 8 hours

Drop factor: 10 gtt/mL

Medication volume: 10 mL (added to the fluid)

Step 1: Calculate the total volume to be infused:

Total volume = Volume of fluid + Volume of medication

Total volume = 500 mL + 10 mL

Total volume = 510 mL

Step 2: Calculate the infusion rate in mL/hr:

Infusion rate (mL/hr) = Total volume (mL) / Infusion time (hr)

Infusion rate (mL/hr) = 510 mL / 8 hr

Infusion rate (mL/hr) = 63.75 mL/hr

Step 3: Calculate the infusion rate in gtt/min:

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

Infusion rate (gtt/min) = 63.75 mL/hr x 10 gtt/mL / 60 min/hr

Infusion rate (gtt/min) = 10.625 gtt/min

Step 4: Round to the nearest whole number:

Infusion rate (gtt/min) ≈ 11 gtt/min
