As it relates to IPC, which environmental issue should an infection preventionist (IP) be most concerned about?

• A. Clean supply is within 18 inches of the sprinkler head.
• B. Bottom shelf of storage units are uncovered.
• C. Item storage blocks hallway egress.
• D. Fire extinguisher checks haven't been completed.

Answer: (B)

Maintaining proper storage conditions is essential to prevent contamination of supplies used in patient care. An uncovered bottom shelf leaves items at floor level exposed to dust, moisture, cleaning residues, and pests, and they can be bumped or splashed during cleaning. This direct exposure increases the chance that microbes contaminate stored items, which can then be used for care and spread infection. Keeping bottom shelves covered or elevating stored items off the floor helps protect against environmental contamination and supports safer, more reliable infection prevention practices. The other issues mentioned are important for safety and maintenance, but they don’t pose as direct a threat to the cleanliness and integrity of stored supplies as an uncovered bottom shelf does.
