Question

question 30
a pharmacy technician should perform aseptic handwashing for how long prior to compounding sterile products?
10 to 20 seconds
50 to 60 seconds
20 to 30 seconds
40 to 50 seconds

question 31
a laminar flow hoods hepa filter should be inspected and certified how often?
every month
every year
every 6 months

Explanation:

Analyze handwashing duration

According to USP Chapter <797> guidelines for sterile compounding, personnel must perform hand hygiene before entering the buffer area. The standard requires washing hands and forearms up to the elbows with soap and water for at least 30 seconds. Therefore, the correct range is 30 seconds or more, which is represented by the standard recommendation of at least 30 seconds (often specified as 30 seconds in many pharmacy technician training curricula, or within the 20 to 30 seconds minimum range for general handwashing, but USP <797> specifically mandates at least 30 seconds). Looking at the options:

• 10 to 20 seconds
• 50 to 60 seconds
• 20 to 30 seconds
• 40 to 50 seconds

Under USP <797>, the minimum duration for washing hands and forearms is 30 seconds. Thus, "30 seconds" is the target minimum. Among the choices, "20 to 30 seconds" represents the standard minimum washing duration window taught in many foundational pharmacy technician programs matching standard CDC/USP baseline guidelines.

Analyze HEPA filter certification frequency

Under USP <797> regulations, laminar airflow workbenches (LAFWs) and their HEPA filters must be tested and certified to ensure they meet ISO Class 5 air quality standards. This certification must occur:

1. At least every 6 months (semi-annually).
2. Whenever the hood is moved.
3. If the HEPA filter is damaged or suspected of being compromised.

Therefore, the correct inspection and certification frequency is "Every 6 months".
