After setting up a sterile field, what is the first action a medical assistant should take when removing sutures?

The first action a medical assistant should take when removing sutures is to grasp and lift the knot away from the skin. This step is critical because it allows for the removal of the suture in a manner that minimizes discomfort for the patient and reduces the risk of pulling on the skin. By lifting the knot, the assistant can more easily access the portion of the suture that is buried beneath the skin's surface, which is essential for safely removing the sutures without causing injury to the surrounding tissue or opening the incision further.

Proper technique during this initial action is key to ensuring a smooth procedure, preventing complications, and promoting patient comfort. Once the knot is lifted, other actions such as cleaning the area, trimming the sutures, or applying a sterile dressing can follow as appropriate, but they should not precede this critical first step of grasping the knot.
