AOTA Infection Control & Prevention 3 — Questions and Answers
Question 1: Which transmission-based precaution category applies to a client diagnosed with chickenpox (varicella) attending sensory integration therapy?
- Contact precautions only
- Droplet precautions only
- Airborne and contact precautions (Correct answer)
- Standard precautions only
Correct answer: Airborne and contact precautions
Varicella requires both airborne precautions (due to aerosolized virus) and contact precautions (due to infectious skin lesions).
Question 2: When cleaning a therapy ball that is shared among multiple pediatric clients, which cleaning sequence is correct?
- Disinfect first, then clean with detergent
- Clean with detergent first, then disinfect (Correct answer)
- Wipe with alcohol wipe only — no additional steps needed
- Rinse with water only between clients
Correct answer: Clean with detergent first, then disinfect
Organic matter must be removed with detergent before disinfection because soiling can inactivate many disinfectants.
Question 3: A sensory integration therapist works in a school setting. A student with a draining wound attends therapy. Under Standard Precautions, what is required?
- Full PPE including gown, gloves, mask, and eye protection
- Gloves when there is risk of contact with drainage (Correct answer)
- N95 mask only since wounds can aerosolize pathogens
- No additional precautions beyond normal practice
Correct answer: Gloves when there is risk of contact with drainage
Standard Precautions require gloves when there is anticipated contact with blood, body fluids, or wound drainage.
Question 4: Which hepatitis virus is most commonly transmitted through contaminated surfaces or fomites in a pediatric therapy environment?
- Hepatitis A (Correct answer)
- Hepatitis B
- Hepatitis C
- Hepatitis D
Correct answer: Hepatitis A
Hepatitis A is a fecal-oral pathogen that survives on surfaces for weeks, making it the primary surface-transmission risk in pediatric settings.
Question 5: An OT student is about to assist with a sensory feeding group and has a small uncovered cut on their finger. What is the correct action?
- Apply gloves and proceed with the group activity (Correct answer)
- Cover the cut with a bandage only, no gloves needed
- Withdraw from the activity until fully healed
- Apply gloves only if the cut is actively bleeding
Correct answer: Apply gloves and proceed with the group activity
Non-intact skin is an exposure risk; covering with a glove provides a barrier that protects both the therapist and the client.
Question 6: Regarding the laundering of weighted vests used in sensory integration therapy, which practice best prevents cross-contamination?
- Launder only when visibly soiled
- Assign one vest per client and launder between uses (Correct answer)
- Wash all vests together weekly in cold water
- Spray with disinfectant between client uses instead of laundering
Correct answer: Assign one vest per client and launder between uses
Assigning individual vests and laundering between uses prevents pathogen transfer and is the infection-control standard for fabric therapy items.
Question 7: Which action by a therapist best demonstrates the principle of 'source control' in a post-pandemic sensory integration clinic?
- Requiring clients to wear masks when symptomatic (Correct answer)
- Increasing the frequency of surface disinfection after each session
- Installing UV-C lights in the therapy gym
- Using only single-use therapy materials
Correct answer: Requiring clients to wear masks when symptomatic
Source control targets the infectious source (the person) by reducing pathogen release into the environment, most commonly through masking when symptomatic.
