One of Orem's Self-Care Requisites is maintenance of sufficient intake of air.

• A. Maintenance of sufficient intake of air
• B. Maintenance of social relationships
• C. Promotion of restful sleep
• D. Prevention of disease

Answer: (A)

Orem's framework centers on universal self-care requisites that everyone should meet to stay healthy, and one of these requisites is maintaining a sufficient intake of air. Adequate oxygen is essential for cellular respiration and energy production; without it, tissues become hypoxic and organ systems can fail. Because oxygen supply underpins virtually every physiological process, actively ensuring good air intake—through a clear airway, proper breathing, and a healthy environment—is a foundational self-care demand.

The other options touch on related health goals but don’t represent one of the universal self-care requisites. Social relationships relate to psychosocial well-being, restful sleep falls under the broader idea of balancing activity and rest, and prevention of disease is a wide goal that isn’t listed as a universal self-care requisite in this framework.
