When removing sutures from a patient's leg, what is the appropriate action to take after setting up a sterile field?

Grasping and lifting the knot away from the skin is the correct action to take when removing sutures. This method ensures that the suture is released from the tissue without causing additional trauma or pulling on the surrounding skin. By lifting the knot, the practitioner can easily access the suture without compromising the healing tissue.

In this process, it's crucial to maintain a sterile field to minimize the risk of infection, and careful handling of the suture helps in promoting optimal healing conditions. This technique not only allows for a smoother removal of the sutures but also helps in reducing discomfort for the patient during the procedure.

Understanding the importance of proper technique in suture removal reinforces the need for careful surgical practices and patient care, which are essential components of a medical assistant's training and responsibilities.
