IV Infection Control & Sterile Technique Flashcards

Which of the following is a key principle of aseptic non-touch technique (ANTT) in IV therapy?

Answer: Key parts and key sites must never be touched or contaminated

ANTT requires that key parts (e.g., needle tips, syringe tips) and key sites (e.g., catheter hubs) are identified and protected from touch contamination throughout any IV procedure.

When should sterile gloves be used instead of clean gloves for IV therapy procedures?

Answer: For central venous catheter insertion and other procedures requiring sterile technique per facility policy

Sterile gloves are required for central venous catheter insertion and other procedures designated as sterile technique per INS and CDC guidelines.

Which IV solution type requires the most frequent administration set changes due to higher infection risk?

Answer: Lipid emulsions (including those in total parenteral nutrition)

Lipid-containing IV solutions support microbial growth and require tubing changes every 12–24 hours to prevent infection.

A nurse must urgently insert a peripheral IV catheter without optimal skin prep. What is the most important follow-up action?

Answer: Replace the catheter at a new site within 48 hours using proper aseptic technique

Catheters inserted under emergency conditions without full aseptic technique should be replaced at a new site within 48 hours when the patient is stable.

What is the purpose of using an in-line filter for IV infusions?

Answer: To remove particulate matter, air, and some microorganisms from the infusion

In-line filters remove particulate matter, air, and certain microorganisms from IV infusions, reducing the risk of infusion-related complications.

Which of the following is a recommended strategy to reduce CLABSI (central line-associated bloodstream infection) rates?

Answer: Implementation of central line insertion bundles including hand hygiene, maximal barrier precautions, and chlorhexidine antisepsis

Central line insertion bundles — combining hand hygiene, maximal barrier precautions, chlorhexidine skin prep, optimal site selection, and daily necessity review — are the evidence-based strategy to reduce CLABSI.
