What is the risk level assigned to preparations exposed to high air quality risks?

The correct answer is "High" because preparations that are exposed to high air quality risks, such as those that may be compounded in an environment not controlled by ISO class 5 conditions or those potentially exposed to contamination during the compounding process, fall under the high-risk category in sterile compounding.

In high-risk conditions, there is a significant likelihood of microbial contamination, which can compromise patient safety if these preparations are administered. This category includes situations where non-sterile ingredients are used, or where compounded preparations are stored in conditions that do not adequately protect them from environmental hazards.

Understanding risk levels in sterile compounding is crucial for ensuring patient safety and adhering to standard practices established by USP 797. This regulation emphasizes the importance of maintaining strict cleanliness and controlled environments to minimize contamination and ensure the integrity of compounded sterile preparations.
