ECC Safety & Infection Control 3 — Questions and Answers
Question 1: According to OSHA bloodborne pathogen standards, equine practitioners who handle animals with skin lesions should treat all biological material as:
- Low risk unless visibly infected
- Potentially infectious using Standard Precautions (Correct answer)
- Safe after vaccination against common pathogens
- Non-hazardous in outdoor farm settings
Correct answer: Potentially infectious using Standard Precautions
Standard Precautions require treating all blood and biological material as potentially infectious regardless of the perceived infection status of the animal.
Question 2: Which of the following is a zoonotic disease that equine chiropractic practitioners are at risk for through wound contamination?
- West Nile Virus
- Strangles (Streptococcus equi)
- Leptospirosis (Correct answer)
- Equine Influenza
Correct answer: Leptospirosis
Leptospirosis is a zoonotic bacterial infection transmitted via contact with urine or contaminated water, posing a genuine occupational risk to equine practitioners.
Question 3: The safest positioning for a practitioner when performing cervical adjustments on a standing horse is:
- Directly in front of the horse's nose
- Lateral to the neck, outside the strike zone of forelegs (Correct answer)
- Behind the shoulder with one hand on the withers
- Straddling the neck while the horse is cross-tied
Correct answer: Lateral to the neck, outside the strike zone of forelegs
Standing lateral to the neck, outside the arc of the horse's strike zone, protects the practitioner from being struck by the forelimbs or head during an adjustment reaction.
Question 4: Hand hygiene between equine patients should be performed using:
- Cold water rinse only
- Alcohol-based hand rub of at least 60% ethanol for visibly clean hands (Correct answer)
- Antibacterial wipes stored in the vehicle
- Soap and water only, as alcohol is ineffective on equine pathogens
Correct answer: Alcohol-based hand rub of at least 60% ethanol for visibly clean hands
An alcohol-based hand rub with at least 60% ethanol is effective and appropriate for visibly clean hands between patients; soap and water is required when hands are visibly soiled.
Question 5: When treating a horse in a group pasture setting, the most important safety measure before beginning any chiropractic work is:
- Administer a sedative to reduce movement
- Separate the patient horse from the herd and secure it (Correct answer)
- Work quickly to minimize time exposed to other horses
- Place all instruments on the ground for easy access
Correct answer: Separate the patient horse from the herd and secure it
Separating and securing the patient horse eliminates the risk of interference or kicks from other horses in the herd, which is the primary safety hazard in a pasture setting.
Question 6: Which characteristic makes Clostridium tetani particularly dangerous in the equine stable environment?
- It is airborne and spreads rapidly
- Its spores persist in soil and manure for years (Correct answer)
- It is resistant to all common disinfectants
- It causes immediate visible symptoms within 24 hours
Correct answer: Its spores persist in soil and manure for years
C. tetani forms highly resistant spores that can survive in soil and manure for years, posing a persistent wound-contamination risk in stable environments.
Question 7: A practitioner notices a horse has an open wound near the area requiring adjustment. The correct action is:
- Adjust the area and apply wound spray after
- Avoid direct pressure over the wound and use sterile draping if any contact is necessary (Correct answer)
- Cancel the entire appointment without rescheduling
- Disinfect the wound thoroughly before proceeding normally
Correct answer: Avoid direct pressure over the wound and use sterile draping if any contact is necessary
Open wounds should not receive direct manipulation; the practitioner should avoid pressure over the wound site and use sterile draping if proximity contact is unavoidable, following aseptic principles.
