Maslow's Hierarchy of Needs (1943) is arranged as follows (bottom to top):

1. Physiological needs — food, water, shelter, air, warmth (FIRST priority)
2. Safety and security needs
3. Love and belonging needs
4. Esteem needs
5. Self-actualization

In community health nursing, physiological needs such as nutrition, clean water, and basic sanitation must be addressed before higher-level needs. A Charge Nurse must apply this framework when prioritizing nursing interventions for community patients.
