Question

a pharmacy technician should wear an n95 respirator when working with a patient who requires which of the following types of isolation precautions?
○ contact
○ airborne
○ bloodborne
○ droplet

question 16
1 point
which of the following international organization for standardization (iso) class standards is required for a direct compounding area (dca)?
○ iso 8
○ iso 5
○ iso 3

Explanation:

First Question (Isolation Precautions):

To determine when an N95 respirator is used, we analyze each isolation type:

• Contact: Requires gloves and gown, not N95.
• Airborne: Pathogens spread via airborne particles (e.g., TB, measles). N95 respirators filter small airborne particles, so they are used here.
• Bloodborne: Involves blood/body fluids; requires gloves, gown, etc., not N95.
• Droplet: Requires surgical mask (filters larger droplets), not N95.

Direct Compounding Areas (DCA) in pharmacies require strict air quality. ISO 5 (Class 100) is the standard for areas where sterile products are compounded, as it has very low particle counts. ISO 8 is less strict (for non-sterile or less critical areas), and ISO 3 is overly strict (not required for DCA).

Answer:

B. Airborne

Second Question (ISO Class for DCA):
