Question

a pharmacy technician receives a prescription for cyclophosphamide 5 mg/m2 qd. the patients body surface area (bsa) is 0.82 m2. which of the following is the dosage amount in mg? 25 mg 4.1 mg 16 mg 5.82 mg question 40 a pharmacy technician is preparing to dispense a prescription with the following instructions: 1 capsule po tid for 7 days. how many capsules should the technician dispense for this prescription?

Explanation:

Step1: Identify the formula for dosage calculation

The dosage is calculated by multiplying the dosage per body surface area (mg/m²) by the patient's body surface area (m²). The formula is: Dosage (mg) = Dosage per BSA (mg/m²) × BSA (m²)

Step2: Plug in the given values

We know that the dosage per BSA is 5 mg/m² and the patient's BSA is 0.82 m². So we substitute these values into the formula: Dosage = \( 5 \, \text{mg/m}^2 \times 0.82 \, \text{m}^2 \)

Step3: Perform the multiplication

Calculating \( 5 \times 0.82 \), we get \( 4.1 \). So the dosage amount is 4.1 mg.

Answer:

4.1 mg (corresponding to the option "4.1 mg")
