CBIC Hand Hygiene 5

Question 1

Which of the following best describes the 'Hawthorne effect' as it relates to hand hygiene compliance monitoring?

Accepted Answer

Observed compliance rates are artificially elevated when staff know they are being watched

Answer

The Hawthorne effect causes observed compliance to be higher than actual compliance because staff modify behavior when they know they are being observed.

Question 2

In a long-term care facility, which resident population characteristic most increases the importance of strict hand hygiene by staff?

Accepted Answer

Residents who are immunocompromised or have indwelling devices

Answer

Immunocompromised residents and those with indwelling devices are at highest risk for healthcare-associated infections from pathogen transmission.

Question 3

When alcohol-based hand rub is used correctly, which organism is it LEAST effective against?

Accepted Answer

Clostridioides difficile spores

Answer

Alcohol-based hand rubs are ineffective against C. difficile spores because spores have protective coats that resist alcohol denaturation.

Question 4

An ICP is analyzing hand hygiene product data and finds that lotion use increased after switching to a new hand rub. This likely indicates:

Accepted Answer

The new product is more drying or irritating to skin

Answer

Increased lotion use after a product switch suggests the new hand rub causes more skin dryness or irritation, a key driver of non-compliance.

Question 5

Which statement about jewelry and hand hygiene in healthcare settings is most accurate?

Accepted Answer

Rings should be removed before surgical hand antisepsis

Answer

Rings and other jewelry should be removed before surgical hand antisepsis because they prevent adequate scrubbing of the subungual and periungual areas.
