DHA Nursing Infection Prevention and Control 2 — Questions and Answers
Question 1: What is the DHA requirement for healthcare worker vaccination?
- Vaccination is optional for all staff
- Mandatory vaccinations including Hepatitis B, influenza, and other role-specific immunizations as per DHA occupational health policy (Correct answer)
- Only Hepatitis B vaccination is required
- No vaccinations are required
Correct answer: Mandatory vaccinations including Hepatitis B, influenza, and other role-specific immunizations as per DHA occupational health policy
DHA requires healthcare workers to maintain current vaccinations including Hepatitis B (with confirmed immunity), annual influenza vaccination, and other immunizations based on role and patient population exposure.
Question 2: How should DHA nurses handle contaminated linen?
- Mix with regular laundry
- Place in designated color-coded bags at the point of use, minimize handling, and do not sort or rinse at the bedside (Correct answer)
- Rinse before placing in laundry bag
- Store in the patient room until end of shift
Correct answer: Place in designated color-coded bags at the point of use, minimize handling, and do not sort or rinse at the bedside
DHA protocols require contaminated linen to be placed in appropriate color-coded bags at the point of use, handled minimally to reduce contamination spread, and never sorted or rinsed at the bedside.
Question 3: What is the DHA protocol for environmental cleaning of isolation rooms?
- Clean the same as regular rooms
- Enhanced cleaning with approved disinfectants, dedicated equipment, cleaning from clean to dirty areas, and terminal cleaning upon discharge (Correct answer)
- Only clean after patient discharge
- Cleaning is done by the patient's family
Correct answer: Enhanced cleaning with approved disinfectants, dedicated equipment, cleaning from clean to dirty areas, and terminal cleaning upon discharge
DHA requires enhanced environmental cleaning for isolation rooms using approved hospital-grade disinfectants, dedicated cleaning equipment, systematic clean-to-dirty progression, and thorough terminal cleaning at discharge.
Question 4: What surveillance activities must DHA nurses participate in for infection prevention?
- No surveillance is required
- Monitoring and reporting healthcare-associated infections, surgical site infections, device-related infections, and antimicrobial usage (Correct answer)
- Only reporting outbreaks
- Only completing annual surveys
Correct answer: Monitoring and reporting healthcare-associated infections, surgical site infections, device-related infections, and antimicrobial usage
DHA requires active surveillance participation including monitoring HAIs (CLABSI, CAUTI, VAP, SSI), reporting notifiable diseases, tracking antimicrobial usage, and participating in outbreak investigations.
Question 5: What is the DHA standard for personal protective equipment (PPE) donning and doffing sequence?
- No specific sequence is required
- Don: gown, mask/respirator, goggles, gloves; Doff: gloves, goggles, gown, mask/respirator with hand hygiene between steps (Correct answer)
- Put everything on simultaneously
- Only follow sequence during COVID outbreaks
Correct answer: Don: gown, mask/respirator, goggles, gloves; Doff: gloves, goggles, gown, mask/respirator with hand hygiene between steps
DHA follows WHO/CDC PPE sequence: donning progresses from gown to mask to eye protection to gloves, while doffing removes the most contaminated items first (gloves) with hand hygiene between each step.
Question 6: What is the DHA requirement for antibiotic stewardship in nursing practice?
- Nurses have no role in antibiotic stewardship
- Ensure correct timing of antibiotic administration, obtain cultures before first dose, monitor for adverse effects, and report antibiotic duration (Correct answer)
- Only administer antibiotics as ordered
- Only physicians participate in stewardship
Correct answer: Ensure correct timing of antibiotic administration, obtain cultures before first dose, monitor for adverse effects, and report antibiotic duration
DHA nursing responsibilities in antibiotic stewardship include timely administration (within 1 hour of order), obtaining cultures before first antibiotic dose, monitoring for adverse effects, and tracking treatment duration.
