CBIC Hand Hygiene 4 — Questions and Answers
Question 1: In an ICU setting, which hand hygiene 'moment' is most frequently missed according to observational studies?
- Before touching a patient
- After touching patient surroundings (Correct answer)
- Before a clean/aseptic procedure
- After body fluid exposure risk
Correct answer: After touching patient surroundings
Studies consistently show that 'after touching patient surroundings' (Moment 5) has the lowest compliance rates in high-acuity settings.
Question 2: Which skin condition is an absolute contraindication to performing invasive procedures without specific infection control clearance?
- Mild contact dermatitis on the forearm
- Active herpetic whitlow on a finger (Correct answer)
- Mild eczema on the elbow
- Dry skin with superficial cracking
Correct answer: Active herpetic whitlow on a finger
Herpetic whitlow (HSV on the finger) can be transmitted to patients during invasive procedures and requires work restriction until healed.
Question 3: An ICP is evaluating hand hygiene product efficacy. Which regulatory body must clear alcohol-based hand rubs used in U.S. healthcare settings as OTC drug products?
- CDC
- EPA
- FDA (Correct answer)
- OSHA
Correct answer: FDA
The FDA regulates alcohol-based hand rubs as over-the-counter (OTC) drug products and must clear them for antimicrobial claims.
Question 4: A hospital notices a cluster of MRSA infections in the NICU. Which hand hygiene intervention has the strongest evidence for reducing MRSA transmission?
- Universal glove use for all patient contacts
- Increased frequency of hand hygiene with ABHR (Correct answer)
- Routine culture of staff hands
- Mandatory nail polish removal for all staff
Correct answer: Increased frequency of hand hygiene with ABHR
Improving hand hygiene frequency and compliance with alcohol-based hand rub is the most evidence-based intervention to reduce MRSA transmission.
Question 5: Which statement about alcohol-based hand rub and glove use is correct?
- Gloves eliminate the need for hand hygiene before patient contact
- Hand hygiene before donning gloves prevents contamination of the sterile field (Correct answer)
- Gloves may be reused between patients if ABHR is applied between uses
- Hand hygiene is only required when gloves are visibly soiled
Correct answer: Hand hygiene before donning gloves prevents contamination of the sterile field
Hand hygiene before gloving prevents pathogens on hands from potentially penetrating micro-tears in gloves and contaminating a sterile field.
Question 6: The WHO 'Institutional Safety Climate' component of the hand hygiene strategy refers to:
- Installing HEPA filters in all patient care areas
- Leadership commitment and a culture that prioritizes patient safety (Correct answer)
- Ensuring adequate staffing ratios for hand hygiene compliance
- Mandating isolation precautions for all new admissions
Correct answer: Leadership commitment and a culture that prioritizes patient safety
Institutional safety climate involves active leadership support and creating an organizational culture where hand hygiene is a patient safety priority.
Question 7: Fingernail length recommendations for healthcare workers state that nails should be kept:
- No longer than 0.5 inches beyond fingertip
- No longer than 0.25 inches beyond fingertip (Correct answer)
- Trimmed to the fingertip level
- As short as comfortable for the individual
Correct answer: No longer than 0.25 inches beyond fingertip
CDC and most infection control guidelines recommend natural nails no longer than 0.25 inches (approximately 6 mm) beyond the fingertip.
