VA-BC Infection Prevention & Complication Management — Questions and Answers
Question 1: Which technique is essential to prevent catheter-related infections?
- Wearing perfume
- Changing gloves frequently
- Hand hygiene (Correct answer)
- Using tape only
Correct answer: Hand hygiene
Hand hygiene, through thorough handwashing or the use of alcohol-based hand rub, is the single most critical measure to prevent the transmission of microorganisms. Adhering to strict hand hygiene protocols before and after any contact with the patient or catheter significantly reduces the risk of catheter-related infections.
Question 2: What is a common complication of vascular access devices?
- Bronchitis
- Sinusitis
- Phlebitis (Correct answer)
- Conjunctivitis
Correct answer: Phlebitis
Phlebitis, which is the inflammation of a vein, is a very common complication associated with vascular access devices. It can be caused by mechanical irritation from the catheter, chemical irritation from infused solutions, or bacterial infection, leading to pain, redness, and swelling along the vein.
Question 3: Which sign may indicate an infection at the catheter site?
- Dryness
- Coolness
- Redness and swelling (Correct answer)
- Numbness
Correct answer: Redness and swelling
Redness (erythema) and swelling (edema) at the catheter insertion site are classic indicators of inflammation or infection. These signs suggest a localized immune response to pathogens or irritation, prompting further assessment and intervention to prevent more serious complications.
Question 4: How often should transparent dressings be changed?
- Daily
- Every 3 days
- Every 5–7 days (Correct answer)
- Once a month
Correct answer: Every 5–7 days
Transparent semipermeable dressings for vascular access sites should typically be changed every 5–7 days. This schedule balances maintaining a sterile barrier with minimizing unnecessary manipulation, allowing for continuous visualization of the insertion site while reducing the risk of infection.
Question 5: What is a key measure to prevent central line-associated bloodstream infections (CLABSI)?
- Quick insertion
- Minimal cleaning
- Maximal sterile barriers (Correct answer)
- Room ventilation
Correct answer: Maximal sterile barriers
The use of maximal sterile barriers during central line insertion is a cornerstone strategy to prevent Central Line-Associated Bloodstream Infections (CLABSI). This involves the healthcare provider wearing a sterile gown, sterile gloves, mask, and cap, and using a large sterile drape to cover the patient, creating a sterile field that minimizes pathogen introduction.
Question 6: What should be done if a catheter site appears infected?
- Ignore it
- Apply lotion
- Report to provider (Correct answer)
- Tighten dressing
Correct answer: Report to provider
If a catheter site appears infected, it is critical to promptly report these findings to the healthcare provider. Early notification allows for timely assessment, diagnostic testing (e.g., blood cultures), and initiation of appropriate treatment, which is essential to prevent the infection from escalating to a systemic bloodstream infection.
Question 7: Which solution is commonly used to disinfect insertion sites?
- Alcohol
- Soap
- Chlorhexidine (Correct answer)
- Saline
Correct answer: Chlorhexidine
Chlorhexidine gluconate (CHG) is the recommended antiseptic solution for disinfecting vascular access insertion sites. It offers broad-spectrum antimicrobial activity against bacteria, fungi, and viruses, along with a persistent residual effect that continues to kill microorganisms on the skin for an extended period after application.
Question 8: What is an air embolism?
- Blocked vein
- Bleeding
- Air in bloodstream (Correct answer)
- Cold hands
Correct answer: Air in bloodstream
An air embolism occurs when air enters the bloodstream, typically through an open central venous catheter lumen or during insertion/removal. This can lead to serious and potentially life-threatening complications as the air bubble travels to the heart and lungs, obstructing blood flow and oxygen exchange.
Question 9: What PPE should be used when cleaning a catheter site?
- Hairnet only
- Goggles only
- Gloves and mask (Correct answer)
- Shoes
Correct answer: Gloves and mask
When cleaning a catheter site, both gloves and a mask are essential PPE. Gloves protect the healthcare worker from contact with blood or body fluids, while a mask protects the patient from potential respiratory droplets expelled by the caregiver, maintaining a clean field and preventing infection.
