Final answer:
In the care of a patient with a sealed radiation implant for cervical cancer, the appropriate intervention is to maintain a safe distance from the patient, following radiation protection measures.
Step-by-step explanation:
When caring for a patient with a sealed radiation implant for cervical cancer, it is crucial to follow radiation protection measures to ensure the safety of the patient, healthcare providers, and visitors. One of the key interventions should be to c) Keep a safe distance from the client, as per the principles of radiation safety which entail maintaining as much distance from the radiation source as possible to significantly decrease radiation intensity exposure. This aligns with the fact that radiation intensity drops inversely proportional to the square of the distance from the source. Limiting visitor time and using shielding are also important measures, but in this case, keeping a safe distance is the correct intervention to include in the plan of care.
