Final answer:
The correct term for the process occurring when a technician's hands get closer to the air vent than the CSP within a laminar airflow hood, disrupting sterile conditions, is shadowing.
Step-by-step explanation:
The question relates to a situation in a compounding pharmacy where technicians work in a laminar airflow hood to prepare sterile compounds. When objects are placed inside the hood, a zone of turbulence can be created, which disrupts the laminar flow. The correct term for the process that occurs when a technician's hands are closer to the air vent than the Compound Sterile Preparation (CSP) is d. shadowing. Shadowing refers to the obstruction caused by the technician's hands that can potentially block the airflow, leading to the creation of an area with reduced airflow where contaminants can accumulate, thus increasing the risk of contamination.
