Sterile technique for invasive lines primarily aims to prevent which risk?

• A. Infection
• B. Bleeding
• C. Allergic reaction
• D. Pain

Answer: (A)

Sterile technique for invasive lines is focused on preventing infection. When a line is inserted, there’s a direct path for microorganisms to enter the body, which can lead to local infections at the insertion site or bloodstream infections that can become serious. By creating and maintaining a sterile field—hand hygiene, sterile gloves and equipment, skin antisepsis, draping, and minimizing contact with sterile surfaces—you reduce the chance that bacteria are introduced during the procedure. This is why infection prevention is the primary goal.

Bleeding, allergic reactions, and pain are governed by different factors: bleeding relates to how well the vessel is controlled and how coagulation is managed; allergic reactions depend on patient sensitivities and materials used; pain is addressed with anesthesia and pain control. Sterility minimizes infection risk, which is why it’s the best answer.
