PTSD Infection Control & Prevention 2 — Questions and Answers
Question 1: Which hand hygiene method is preferred when hands are visibly soiled with blood or body fluids?
- Alcohol-based hand rub
- Soap and water (Correct answer)
- Antiseptic wipes
- Glove change only
Correct answer: Soap and water
Soap and water must be used when hands are visibly soiled because alcohol-based rubs do not physically remove organic material.
Question 2: A clinician is treating a patient with known MRSA. Which type of transmission-based precaution is required?
- Droplet precautions
- Airborne precautions
- Contact precautions (Correct answer)
- Reverse isolation
Correct answer: Contact precautions
MRSA is spread primarily through direct contact with infected wounds or colonized skin, requiring contact precautions.
Question 3: What is the minimum recommended duration for performing hand hygiene with an alcohol-based hand rub?
- 5 seconds
- 10 seconds
- 20 seconds (Correct answer)
- 30 seconds
Correct answer: 20 seconds
The CDC recommends rubbing hands together with alcohol-based hand rub for at least 20 seconds until dry.
Question 4: In a mental health facility, a patient with active pulmonary tuberculosis should be placed in which type of room?
- Positive pressure room
- Standard private room
- Airborne infection isolation room (Correct answer)
- Cohort room with other TB patients
Correct answer: Airborne infection isolation room
Active pulmonary TB requires an airborne infection isolation room with negative pressure and at least 6-12 air changes per hour.
Question 5: Which personal protective equipment (PPE) is required when performing a procedure that may generate splashes of blood or body fluids?
- Gloves only
- Gloves and gown
- Gloves, gown, and eye protection (Correct answer)
- N95 respirator only
Correct answer: Gloves, gown, and eye protection
Splash-generating procedures require gloves, gown, and eye protection (goggles or face shield) to protect mucous membranes and skin.
Question 6: What does the 'chain of infection' model help healthcare workers understand?
- How to document patient infections
- The sequence of elements necessary for infection transmission (Correct answer)
- Which antibiotics to prescribe
- How to report infectious diseases to authorities
Correct answer: The sequence of elements necessary for infection transmission
The chain of infection model identifies six links—agent, reservoir, portal of exit, mode of transmission, portal of entry, and susceptible host—that must all be present for infection to occur.
Question 7: When removing contaminated gloves, which step should occur first?
- Wash gloved hands with soap and water
- Grasp the outside of one glove near the wrist and peel off (Correct answer)
- Pull gloves off by the fingertips
- Remove gloves simultaneously by pulling both off at once
Correct answer: Grasp the outside of one glove near the wrist and peel off
The correct technique is to grasp the outside of one glove near the wrist and peel it off, turning it inside out to contain contamination.
