Ambulatory Care Test Infection Control and Prevention 1 — Questions and Answers
Question 1: Which hand hygiene agent is most effective against Clostridioides difficile (C. diff) spores in an ambulatory care setting?
- Alcohol-based hand rub
- Soap and water (Correct answer)
- Chlorhexidine gluconate
- Povidone-iodine
Correct answer: Soap and water
Soap and water is required for C. diff because alcohol-based hand rubs do not effectively kill spores.
Question 2: What is the correct order of personal protective equipment (PPE) removal in an ambulatory care clinic?
- Gloves, gown, mask, eye protection (Correct answer)
- Gown, gloves, eye protection, mask
- Mask, gloves, gown, eye protection
- Eye protection, gown, gloves, mask
Correct answer: Gloves, gown, mask, eye protection
CDC guidelines specify removing gloves first, then gown, then mask/respirator, then eye protection to prevent self-contamination.
Question 3: A patient presents with suspected active pulmonary tuberculosis. Which transmission-based precaution is required?
- Contact precautions
- Droplet precautions
- Airborne precautions (Correct answer)
- Standard precautions only
Correct answer: Airborne precautions
Pulmonary TB is transmitted via airborne particles and requires airborne precautions including an N95 respirator and negative-pressure room.
Question 4: Which of the following is a common healthcare-associated infection (HAI) risk unique to ambulatory care settings?
- Catheter-associated urinary tract infection
- Surgical site infection from same-day procedures (Correct answer)
- Ventilator-associated pneumonia
- Central line-associated bloodstream infection
Correct answer: Surgical site infection from same-day procedures
Same-day surgical procedures in ambulatory settings carry risk of surgical site infection if sterile technique and wound care instructions are not followed.
Question 5: Standard precautions in ambulatory care apply to which of the following?
- Only visibly bloody body fluids
- All patients with known infections
- All patients regardless of diagnosis (Correct answer)
- Immunocompromised patients only
Correct answer: All patients regardless of diagnosis
Standard precautions are applied to all patients regardless of diagnosis because infectious status is not always known.
Question 6: A reusable medical instrument used on a patient with intact skin requires which level of disinfection?
- High-level disinfection
- Sterilization
- Low-level disinfection (Correct answer)
- No disinfection required
Correct answer: Low-level disinfection
Items contacting intact skin are non-critical and require low-level disinfection per the Spaulding classification.
