ACT Infection Control & Prevention 2 — Questions and Answers
Question 1: Which CDC transmission-based precaution category is required for a patient with active pulmonary tuberculosis?
- Contact precautions
- Droplet precautions
- Airborne precautions (Correct answer)
- Standard precautions only
Correct answer: Airborne precautions
Airborne precautions are required for TB because M. tuberculosis is transmitted via small droplet nuclei that remain suspended in air.
Question 2: A therapist notices a client has an open wound with purulent drainage during a session. The FIRST action should be to:
- Complete the session and report later
- Don Don gloves and contact the supervising nurse or physician (Correct answer)
- Cancel all future appointments
- Apply a bandage without PPE
Correct answer: Don Don gloves and contact the supervising nurse or physician
Donning gloves and notifying a medical professional protects both therapist and client from potential pathogen exposure.
Question 3: Which hand hygiene product is MOST effective against Clostridioides difficile spores?
- Alcohol-based hand rub
- Soap and water (Correct answer)
- Chlorhexidine wipes
- Povidone-iodine solution
Correct answer: Soap and water
C. difficile spores are not killed by alcohol; soap and water physically removes them from hands.
Question 4: The recommended sequence for donning PPE in a contact precaution room is:
- Gown → Mask → Goggles → Gloves (Correct answer)
- Gloves → Gown → Mask → Goggles
- Mask → Goggles → Gown → Gloves
- Goggles → Gloves → Gown → Mask
Correct answer: Gown → Mask → Goggles → Gloves
CDC guidelines specify gown first, then mask/goggles, then gloves so that gloves cover gown cuffs and remain the last item contaminated.
Question 5: A behavioral health facility is experiencing an outbreak of norovirus. Which measure is MOST important to reduce transmission?
- Initiating antiviral prophylaxis for all staff
- Cohorting affected clients and enforcing hand hygiene (Correct answer)
- Increasing ventilation to HEPA-filter standard
- Administering flu vaccine to all residents
Correct answer: Cohorting affected clients and enforcing hand hygiene
Cohorting ill individuals and rigorous hand hygiene are the cornerstones of norovirus outbreak control.
Question 6: When performing a telehealth session, infection control responsibilities of the clinician PRIMARILY include:
- Disinfecting the client's home surfaces remotely
- Maintaining a clean workspace and disinfecting shared devices (Correct answer)
- Wearing full PPE during video calls
- Obtaining airborne infection isolation for the session
Correct answer: Maintaining a clean workspace and disinfecting shared devices
During telehealth, clinicians should maintain a clean personal workspace and sanitize shared equipment such as keyboards and microphones.
Question 7: Which bloodborne pathogen has the HIGHEST risk of transmission from a single needlestick exposure?
- HIV
- Hepatitis C virus
- Hepatitis B virus (Correct answer)
- HTLV-I
Correct answer: Hepatitis B virus
Hepatitis B virus has a needlestick transmission risk of approximately 6–30%, far exceeding HIV (~0.3%) and HCV (~1.8%).
