A manifest function of health care is a clear and intentional positive outcome or purpose of the health care system. Among the options provided, the manifest function of health care is:
1. Treatment to alleviate illness or promote healing: This is a manifest function as it directly addresses the core purpose of health care, which is to provide medical care to individuals in need to help them recover from illnesses, injuries, or health conditions. By providing treatment that alleviates illness or promotes healing, the health care system fulfills its intended role of improving the health and well-being of individuals.
The other options mentioned, such as stigmatizing a patient with a mental disorder, prescribing unnecessary drugs and procedures, and extending a country's life expectancy, do not align with the primary purpose of health care as they either involve negative consequences or are not direct outcomes that are intentionally aimed for within the health care system.
I hope this helps clarify the concept of manifest functions of health care for you! If you have any more questions or need further assistance, feel free to ask.
