Question 1

Which organism is most commonly associated with catheter-related bloodstream infections in immunocompromised patients receiving compounded parenteral nutrition?

Accepted Answer

Candida albicans

Answer

Candida albicans is the leading fungal pathogen in catheter-related bloodstream infections, especially in immunocompromised patients on parenteral nutrition.

Question 2

When performing environmental monitoring in a cleanroom, what is the primary purpose of viable air sampling using an active air sampler?

Accepted Answer

To quantify airborne microbial contamination in colony-forming units per cubic meter

Answer

Active air sampling with devices like the RCS or MAS-100 quantifies airborne viable microorganisms expressed as CFU/m³ to confirm ISO class compliance.

Question 3

A compounding technician notices a turbid appearance in a batch of compounded IV bags that were clear at preparation. Which action is the MOST appropriate immediate response?

Accepted Answer

Quarantine the batch and report to the supervising pharmacist for investigation

Answer

Turbidity is a physical indicator of microbial contamination; the batch must be quarantined and the pharmacist notified before any further action is taken.

Question 4

Which disinfectant class is considered sporicidal and is required for decontaminating surfaces after a spill of a spore-forming organism like Clostridium difficile?

Accepted Answer

Chlorine-based agents (bleach)

Answer

Chlorine-based disinfectants (e.g., sodium hypochlorite) are among the few agents with proven sporicidal activity against C. difficile spores.
