What measures are taken to provide comfort while treating symptoms without curing the disease?

The correct choice is palliative measures because these focus on relieving symptoms and improving the quality of life for patients who may be suffering from serious or terminal illnesses. Palliative care is centered on providing comfort and support rather than attempting to cure the underlying disease. This involves addressing pain management, emotional support, and other aspects of a patient's well-being to ensure they can live as fully as possible despite their condition.

Preventative measures, in contrast, are aimed at stopping diseases from occurring in the first place. Cursory care typically refers to minimal attention and may not be comprehensive enough to provide comfort or support adequately. Rehabilitative care focuses on helping patients regain their abilities or health after an illness or injury, which is different from palliative care's goal of comfort for those with ongoing symptoms.

Thus, palliative measures are specifically designed to manage discomfort associated with illness, making this option the most appropriate in the context provided.
