CCHI Safety and Infection Control 4 — Questions and Answers
Question 1: A patient diagnosed with active pulmonary tuberculosis is being treated at an outpatient clinic. What type of isolation precautions should the healthcare interpreter be aware of when entering the room?
- Contact precautions only
- Airborne precautions with N95 respirator (Correct answer)
- Droplet precautions with surgical mask
- Standard precautions are sufficient
Correct answer: Airborne precautions with N95 respirator
Active pulmonary tuberculosis requires airborne precautions, including use of a fit-tested N95 or higher-level respirator, because TB is transmitted via airborne droplet nuclei.
Question 2: An interpreter notices that a nurse did not perform hand hygiene after removing gloves following patient contact. What is the most appropriate action for the interpreter to take?
- Ignore it to avoid interfering with clinical staff
- Immediately wash the interpreter's own hands on the patient's behalf
- Politely remind the nurse about hand hygiene protocol (Correct answer)
- Report the incident to hospital administration immediately
Correct answer: Politely remind the nurse about hand hygiene protocol
Interpreters have a role in patient safety and may appropriately and respectfully remind clinical staff of hand hygiene protocols without overstepping their professional boundaries.
Question 3: Which of the following pathogens requires Contact Precautions in addition to Standard Precautions due to its resistance to common antibiotics?
- Influenza A
- Methicillin-resistant Staphylococcus aureus (MRSA) (Correct answer)
- Streptococcal pharyngitis
- Hepatitis C virus
Correct answer: Methicillin-resistant Staphylococcus aureus (MRSA)
MRSA is a multidrug-resistant organism that spreads through direct contact and requires Contact Precautions, including gloves and gown, in addition to Standard Precautions.
Question 4: A healthcare interpreter is asked to interpret in a procedure room where a sterile field has been established. What should the interpreter do to prevent contaminating the sterile field?
- Stand as close as possible to hear clearly
- Position themselves away from and at a safe distance from the sterile field (Correct answer)
- Touch the sterile drape only with gloved hands
- Enter only after the procedure is complete
Correct answer: Position themselves away from and at a safe distance from the sterile field
Interpreters must maintain a safe distance from sterile fields to avoid contamination; touching or leaning over a sterile field can introduce microorganisms.
Question 5: When interpreting for a patient with C. difficile (C. diff) infection, which hand hygiene method is MOST effective for removing C. diff spores from an interpreter's hands?
- Alcohol-based hand sanitizer
- Soap and water handwashing for at least 20 seconds (Correct answer)
- Antiseptic wipes
- Waterless antimicrobial foam
Correct answer: Soap and water handwashing for at least 20 seconds
C. difficile spores are resistant to alcohol-based sanitizers; soap and water handwashing is required to mechanically remove spores from the hands.
Question 6: An interpreter working in a hospital is offered a patient's food or drink as a gesture of appreciation. What is the most appropriate response from an infection control standpoint?
- Accept it graciously to respect cultural norms
- Accept only sealed, packaged items
- Decline politely, as accepting patient food increases infection risk and violates professional boundaries (Correct answer)
- Disinfect the item before consuming it
Correct answer: Decline politely, as accepting patient food increases infection risk and violates professional boundaries
Accepting food or drink from patients poses infection risks and violates professional boundaries; interpreters should politely decline regardless of cultural context.
Question 7: What does the term 'PPE donning sequence' refer to in a healthcare setting?
- The process of disposing of personal protective equipment after use
- The correct order in which personal protective equipment is put on to prevent self-contamination (Correct answer)
- The schedule for replacing PPE supplies in the facility
- The training required before using personal protective equipment
Correct answer: The correct order in which personal protective equipment is put on to prevent self-contamination
Donning sequence refers to the specific order (gown, mask, eye protection, gloves) for putting on PPE to maximize protection and prevent contamination.
