Final answer:
The adjustment of clamps on an external fixator should be done by the orthopedic surgeon. This task requires specialized medical knowledge and expertise, which is not typically within the purview of nurses, family members, or physical therapists.
Step-by-step explanation:
The orthopedic surgeon is responsible for the adjustment of clamps on an external fixator. This is because the process of adjusting these clamps is critical to the correct healing of the bone and must be carried out with precise medical knowledge and expertise. The surgeon, nurse, and anesthesia professional work together to ensure the recovery and care of the patient are well managed. This includes the understanding that only medical professionals with the appropriate training should perform adjustments to medical devices like an external fixator.
In line with the given options, the correct answer is c) Orthopedic surgeon. Registered nurses, patient's family members, and physical therapists do not typically have the authority or the specialized training required to adjust external fixators, as it involves direct manipulation of the device that stabilizes broken bones.
