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?
21

Explanation:

First Question (Cyclophosphamide Dosage)

Step1: Identify the formula

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

Step2: Plug in the values

Given dosage per BSA is \( 5 \, \text{mg/m}^2 \) and BSA is \( 0.82 \, \text{m}^2 \). So, Dosage = \( 5 \times 0.82 \).

Step3: Calculate the result

\( 5 \times 0.82 = 4.1 \).

Step1: Understand the instructions

"1 capsule po tid for 7 days" means 1 capsule taken orally three times a day for 7 days.

Step2: Calculate daily capsules

Daily capsules = 1 capsule × 3 times a day = 3 capsules per day.

Step3: Calculate total capsules for 7 days

Total capsules = Daily capsules × Number of days = \( 3 \times 7 \).

Step4: Compute the result

\( 3 \times 7 = 21 \).

Answer:

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