Pharmacy Technician Certification Board Practice Exam Practice Question

Correct Answer: D

Rationale: Washing hands for 30 seconds is the most effective method for preventing the spread of infection, as it removes pathogens from the skin, significantly reducing the risk of transmission.

Wearing powdered latex gloves (A) can create a false sense of security and may lead to cross-contamination if not used properly. Cleaning counting trays after use (B) is important but only addresses surface contamination, not the primary source of germs—hands. Putting on shoe covers (C) is less relevant in a pharmacy setting, as hand hygiene directly impacts the risk of infection more than footwear cleanliness.
