BHP Infection Control & Prevention 3 — Questions and Answers
Question 1: The chain of infection model is used to understand disease transmission. Which link, if broken, would be most effective in preventing respiratory illness spread in a group therapy setting?
- Reservoir
- Portal of exit
- Mode of transmission (Correct answer)
- Susceptible host
Correct answer: Mode of transmission
Interrupting the mode of transmission (e.g., masking, ventilation, distancing) is typically the most practical intervention in group settings.
Question 2: According to CDC guidelines, which clients should be placed under droplet precautions in a behavioral health setting?
- Clients with varicella (chickenpox)
- Clients with influenza (Correct answer)
- Clients with C. diff
- Clients with HIV
Correct answer: Clients with influenza
Influenza spreads via respiratory droplets (>5 microns) and requires droplet precautions including surgical masks and private rooms when possible.
Question 3: A client in a residential behavioral health facility refuses to wash their hands before meals. The best response is to:
- Force the client to wash hands citing infection risk
- Document the refusal and allow the client to eat without handwashing
- Educate the client about hand hygiene benefits and offer alternatives like wipes (Correct answer)
- Isolate the client from other residents during mealtimes
Correct answer: Educate the client about hand hygiene benefits and offer alternatives like wipes
Respecting client autonomy while offering education and alternatives (like hand wipes) balances infection control with person-centered care.
Question 4: Which disinfectant level is appropriate for reprocessing non-critical items (items that contact intact skin only) in a behavioral health setting?
- Sterilization
- High-level disinfection
- Low-level disinfection (Correct answer)
- Intermediate-level disinfection
Correct answer: Low-level disinfection
Non-critical items (e.g., blood pressure cuffs) that contact only intact skin require low-level disinfection per the Spaulding classification.
Question 5: A behavioral health professional notices a colleague not performing hand hygiene after client contact. The best course of action is to:
- Ignore it to avoid workplace conflict
- Report it anonymously to administration only
- Politely remind the colleague of hand hygiene policy and model the behavior (Correct answer)
- Document it as a safety concern in the client's chart
Correct answer: Politely remind the colleague of hand hygiene policy and model the behavior
Peer-to-peer reminders are an evidence-based strategy for improving hand hygiene compliance and are part of a safety culture.
Question 6: What is the minimum recommended duration for performing hand hygiene with soap and water to effectively reduce microbial contamination?
- 5 seconds
- 10 seconds
- 20 seconds (Correct answer)
- 60 seconds
Correct answer: 20 seconds
The CDC recommends scrubbing hands with soap and water for at least 20 seconds to effectively reduce microbial load.
Question 7: In infection control, the term 'vector-borne transmission' refers to disease spread via:
- Contaminated water or food
- Living organisms such as mosquitoes or ticks (Correct answer)
- Direct person-to-person contact
- Airborne droplet nuclei
Correct answer: Living organisms such as mosquitoes or ticks
Vector-borne transmission involves living organisms (vectors) such as mosquitoes, ticks, or fleas that carry pathogens from one host to another.
The chain of infection model is used to understand disease transmission.
