Final answer:
Tertiary care refers to specialized medical care provided by specialists in a hospital setting. It may not be successful in health promotion because it focuses on treating diseases rather than preventive measures or long-term evaluations, and it may not be accessible to everyone.
Step-by-step explanation:
Tertiary care refers to specialized medical care provided by specialists in a hospital setting. It involves advanced procedures, complex surgeries, and highly specialized treatments. The reason why tertiary care may not be successful in health promotion is because it focuses mainly on treating diseases and providing acute care, rather than preventive measures or long-term follow-up evaluations. Tertiary care is often expensive and not accessible to everyone, especially in developing or underdeveloped countries where healthcare resources may be limited.
