What is a characteristic feature of towel clamps?

Towel clamps are designed specifically for holding or securing draping materials, such as towels or surgical drapes, in place during medical procedures. A key feature of towel clamps is their pointed ends that can interlock or lock together, allowing for a secure grip on the fabric. This locking mechanism is important as it ensures that the drapes remain stationary and do not shift during a procedure, thus maintaining a sterile environment and aiding in the overall efficiency of surgical tasks.

The other options do not accurately describe the primary function of towel clamps. Monitoring vitals pertains to equipment like sphygmomanometers or pulse oximeters, which are not related to clamps. Gripping the throat is not a function of towel clamps; other instruments would be used for such purposes in medical practice. Lastly, while towel clamps may assist in some aspects of an abdominal examination by securing drapes, their main characteristic does not focus on examinations but rather on securing materials in place during procedures.
