Rationale: Jean Watson developed the Theory of Human Caring, which

Her theory emphasizes the importance of caring relationships, the
transpersonal caring relationship, and the caring moment. Watson's
theory has been influential in shaping nursing education and practice
toward holistic, patient-centered care .
3. The American Nurses Association (ANA) defines nursing as:
A) The diagnosis and treatment of human disease
B) The protection, promotion, and optimization of health and abilities,

, 4|Page
physicians
D) The management of healthcare facilities
Answer: B) The protection, promotion, and optimization of health
and abilities, prevention of illness and injury, alleviation of suffering
through the diagnosis and treatment of human response, and
advocacy in the care of individuals, families, communities, and
populations
Rationale: The ANA's definition of nursing encompasses the full scope
of nursing practice, emphasizing health promotion, illness prevention,
and alleviation of suffering. It highlights nursing's focus on the
"diagnosis and treatment of human response" to health problems,
distinguishing nursing from medicine, which focuses on disease
diagnosis and treatment .
4. Which nursing theorist is known for the Self-Care Deficit Theory,
which focuses on the patient's ability to perform self-care activities?
A) Dorothea Orem
B) Imogene King
C) Martha Rogers
D) Madeleine Leininger

Rationale: Dorothea Orem's Self-Care Deficit Theory proposes that
nursing care is needed when individuals are unable to meet their own
self-care needs. The theory includes three interrelated theories: the
theory of self-care, the theory of self-care deficit, and the theory of
nursing systems. Orem's work has been particularly influential in areas
such as rehabilitation, home health, and chronic disease management .
