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 D

Explanation

Given:

Volume of fluid: 100 mL

Infusion time: 30 minutes

Drop factor: 60 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 / 30 min

Infusion rate (mL/min) = 3.33 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) = 3.33 mL/min x 60 gtt/mL

Flow rate (gtt/min) = 200 gtt/min

Correct Answer is B

Explanation

Given:

Ordered dose of Vancomycin: 500 mg

Infusion rate: 5 mg/kg/hr

Patient weight: 98 lbs

Concentration of Vancomycin: 500 mg/100 mL

Step 1: Convert patient weight from pounds to kilograms:

1 pound (lb) = 0.453592 kilograms (kg)

Patient weight in kg = 98 lbs x 0.453592 kg/lb = 44.462256 kg

Step 2: Calculate the total dose of Vancomycin in mg/hr:

Total dose (mg/hr) = Ordered dose (mg/kg/hr) x Patient weight (kg)

Total dose (mg/hr) = 5 mg/kg/hr x 44.462256 kg

Total dose (mg/hr) = 222.31128 mg/hr

Step 3: Calculate the infusion rate in mL/hr:

Infusion rate (mL/hr) = Total dose (mg/hr) / Concentration (mg/mL)

Infusion rate (mL/hr) = 222.31128 mg/hr / (500 mg/100 mL)

Infusion rate (mL/hr) = 222.31128 mg/hr x (100 mL/500 mg)

Infusion rate (mL/hr) = 44.462256 mL/hr

Step 4: Round to the nearest tenth:

Infusion rate (mL/hr) ≈ 44.5 mL/hr
