A nurse is caring for a client receiving IV therapy. Which action is essential to prevent catheter-related bloodstream infections (CRBSIs)?

A) This choice is incorrect because administering IV medications rapidly may increase the risk of an allergic reaction, especially in a client with a history of multiple drug allergies.

B) This choice is incorrect because switching to oral medications may not be appropriate or feasible for all IV medications. The nurse should consider alternative medications only after performing a thorough allergy assessment and consulting with the healthcare provider.

C) This choice is incorrect because the choice of IV catheter gauge is not directly related to preventing allergic reactions. It should be based on the medication's compatibility and viscosity.

D) This choice is correct. A thorough allergy assessment is essential in a client with a history of multiple drug allergies to identify potential allergens and prevent exposure to allergenic medications. The nurse should communicate allergies to the healthcare team and document them in the client's medical record, using allergy alerts or wristbands, to ensure safe medication administration.

A) This choice is incorrect because administering IV fluids through the largest available catheter is not necessary for preventing CRBSIs. The appropriate catheter size should be based on the client's clinical needs and the prescribed therapy.

B) This choice is incorrect because changing the IV catheter dressing daily is not necessarily recommended unless the dressing is soiled or loose. Frequent dressing changes can increase the risk of contamination and infection. The nurse should follow evidence-based guidelines for catheter care and dressing changes.

C) This choice is correct. Using sterile technique during IV insertion and care is essential for preventing CRBSIs. Sterile technique helps to reduce the risk of introducing pathogens into the bloodstream, which can lead to infection.

D) This choice is incorrect because frequently accessing the IV catheter for blood draws can increase the risk of CRBSIs. The nurse should minimize unnecessary catheter access and follow aseptic technique when drawing blood or administering medications through the catheter.
