A pedicure technician believes that using hand sanitizer between clients is just as effective as washing her hands with soap and water, so she skips handwashing entirely during a busy day. Why is this practice inadequate?
- AHand sanitizer kills more pathogens than soap and water
- BHand sanitizer eliminates the need for gloves during services
- CHand sanitizer does not remove visible soil and organic debris as effectively as soap-and-water handwashing
- DHand sanitizer is not regulated by the EPA and therefore unreliable
Show answer & explanationAnswer & explanation
Correct answer: C. Hand sanitizer does not remove visible soil and organic debris as effectively as soap-and-water handwashing
Hand sanitizer can reduce some pathogens but does not physically remove dirt, oils, or organic debris the way soap-and-water handwashing does; it is a supplement, not a replacement, especially when hands are visibly soiled.
Why the other options are wrong
- A. Soap and water combined with friction is generally more effective for visible soil.
- B. Gloves are still required per standard precautions regardless of sanitizer use.
- D. Many hand sanitizers are EPA/FDA regulated; that's not the core issue.
Hand Sanitizer Limitation
Hand sanitizer reduces microbial load but does not replace soap-and-water handwashing, especially when hands are visibly soiled.
- Handwashing physically removes debris and organic matter
- Sanitizer is a supplement, used between full washes
- Does not replace glove use under standard precautions
Memory trick: Sanitizer sanitizes, but soap scrubs away the dirt sanitizer can't touch.
