Question12. A patient weighs 16.5 kg and is prescribed a medication for $0.4 \mathrm{mg} / \mathrm{kg} /$ dose. The stock strength is $20 \mathrm{mg} / 5 \mathrm{~mL}$ . What volume will you give the patient?

Studdy Solution

STEP 1

1. The patient weighs 16.5 kg.
2. The prescribed medication dosage is 0.4 mg per kg per dose.
3. The stock strength of the medication is 20 mg per 5 mL.
4. We need to calculate the volume of medication to administer to the patient.

STEP 2

1. Calculate the total dosage required for the patient.
2. Determine the volume of medication needed based on the stock strength.

STEP 3

Calculate the total dosage required for the patient.
The dosage is given as 0.4 mg per kg. Therefore, the total dosage for the patient is:
$\text{Total dosage} = \text{Weight of patient} \times \text{Dosage per kg}$ $\text{Total dosage} = 16.5 \, \text{kg} \times 0.4 \, \text{mg/kg}$ $\text{Total dosage} = 6.6 \, \text{mg}$

STEP 4

Determine the volume of medication needed based on the stock strength.
The stock strength is 20 mg per 5 mL. First, find out how many mg are in 1 mL:
$\text{Strength per mL} = \frac{20 \, \text{mg}}{5 \, \text{mL}}$ $\text{Strength per mL} = 4 \, \text{mg/mL}$
Now, calculate the volume needed for the 6.6 mg dosage:
$\text{Volume required} = \frac{\text{Total dosage}}{\text{Strength per mL}}$ $\text{Volume required} = \frac{6.6 \, \text{mg}}{4 \, \text{mg/mL}}$ $\text{Volume required} = 1.65 \, \text{mL}$
The volume of medication to administer to the patient is:
$\boxed{1.65 \, \text{mL}}$
