Final answer:
The nurse's main priority when caring for a patient with hemiplegia is providing a safe environment. Hence, option B is correct.
Step-by-step explanation:
The nurse's main priority when caring for a patient with hemiplegia is providing a safe environment. Hemiplegia refers to paralysis on one side of the body, which often leads to mobility challenges and increased risk of falls. By ensuring a safe environment, the nurse can prevent accidents and promote the patient's well-being.
While educating the patient about their condition and treatment is important, it is not the primary priority when immediate care is needed. Similarly, promoting a positive self-image and helping the patient accept the illness are important aspects of long-term care and emotional support, but they are not the main priority in the immediate care of a patient with hemiplegia.
