VA-BC Infection Prevention & Complication Management

Question 1

Which technique is essential to prevent catheter-related infections?

Accepted Answer

Hand hygiene

Answer

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?

Accepted Answer

Phlebitis

Answer

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?

Accepted Answer

Redness and swelling

Answer

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?

Accepted Answer

Every 5–7 days

Answer

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)?

Accepted Answer

Maximal sterile barriers

Answer

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.
