What action should a PCT take before removing a peripheral IV catheter?

Before removing a peripheral IV catheter, it is essential for a Patient Care Technician to don sterile gloves to maintain aseptic technique and minimize the risk of infection. The use of sterile gloves is a standard practice in healthcare settings, especially when dealing with invasive procedures or sites that have been exposed to potential contaminants.

Using sterile gloves helps in protecting both the patient and the healthcare worker from possible pathogens present on the skin or in the environment. This practice is crucial in ensuring that any bacteria or other microorganisms are not introduced into the bloodstream during the removal of the catheter.

In contrast, the other options do not align with standard protocols for catheter removal. Turning the infusion clamp to the "on" position would not be appropriate, as it could lead to fluid leakage or bleeding at the insertion site. Holding gauze over the site when removing the catheter is prudent for managing any potential bleeding but is done after the catheter is withdrawn, rather than being a preparatory step. Cleaning the area with saline prior to removal is also not necessary, as the focus is on maintaining a sterile field during the procedure rather than cleansing the site right before the catheter is removed. Thus, wearing sterile gloves is the most critical step in ensuring safety and cleanliness during this procedure.
