What is the first step when preparing sterile compounds in a LAFW?
Answer: Allow the hood to run at least 30 minutes before use and clean the work surface with 70% IPA
The LAFW must run for at least 30 minutes before use to establish proper airflow, and the work surface must be cleaned with 70% IPA before beginning preparation.
What is 'coring' in sterile compounding?
Answer: Introduction of rubber particles into a solution when puncturing a vial stopper incorrectly
Coring occurs when a needle punctures the rubber stopper at an improper angle, causing rubber fragments to enter the solution and contaminate it.
Which solution is isotonic and most compatible with blood?
Answer: Normal Saline (0.9% NaCl)
Normal Saline (0.9% NaCl) is isotonic with blood, meaning it has the same osmolality as red blood cells and is widely used as a diluent and IV fluid.
What is the purpose of a HEPA filter in a laminar airflow hood?
Answer: To remove 99.97% of particles ≥0.3 microns from the air to create a sterile environment
HEPA filters remove 99.97% of airborne particles ≥0.3 microns, creating the ISO 5 clean air environment required for sterile compounding.
What should be done if touch contamination occurs during sterile preparation?
Answer: Discard the preparation and start over with new supplies
If touch contamination occurs, the preparation must be discarded and restarted to ensure patient safety, as there is no way to reverse contamination.
What is the recommended hand hygiene procedure before sterile compounding?
Answer: Wash with soap and water for at least 30 seconds, then apply alcohol-based hand sanitizer
Before sterile compounding, hands must be washed for at least 30 seconds with soap and water followed by application of an alcohol-based hand sanitizer.
