What term is used for medical care that focuses on relieving unpleasant symptoms such as pain and nausea?

The correct term for medical care that focuses on relieving unpleasant symptoms such as pain and nausea is palliative care. Palliative care is designed to improve the quality of life for patients facing serious illnesses by addressing their physical, emotional, and psychological needs. It is not limited to end-of-life care, but encompasses support at any stage of a disease, emphasizing comfort and symptom management, which can significantly enhance a patient's overall well-being.

In contrast, parenteral nutrition refers to the administration of nutrients directly into the bloodstream, bypassing the digestive system, and is unrelated to symptom relief. Pathological waste refers to discarded materials from medical procedures that could be potentially infectious or hazardous, which does not pertain to symptom management. Passivity generally describes a lack of response or activity, which does not align with the proactive approach of palliative care in alleviating symptoms.
