Question

17. The client weighs \( 120 \mathrm{lb} \). The medication order for a drug is for \( 200 \mathrm{mcg} / \mathrm{kg} \). The label reads \( 2 \mathrm{mg} / \mathrm{ml} \). a. How many \( \mathrm{ml}

Answer 1

To calculate the required dosage, first convert the client's weight from pounds to kilograms, calculate the total dosage in micrograms, convert it to milligrams, and then find the volume in milliliters using the medication's concentration.

Step-by-step explanation:

The Client weighs 120 lb (pounds). This weight needs to be converted to kilograms to calculate the medication dosage because the medication order is 200 mcg/kg. To convert pounds to kilograms, use the conversion factor (1 lb = 0.453592 kg). Then, calculate the number of milliliters of the drug needed using the information that the label reads 2 mg/ml.

Steps to calculate the dosage:

1. Convert the weight from pounds to kilograms:
   
2. Calculate the total dosage in micrograms:
   
3. Convert the dosage from micrograms to milligrams since the concentration is given in mg/ml:
   
4. Now use the concentration to find the volume of the medication needed in milliliters:
   

The client needs approximately 5.4431 ml of the medication.
