A patient's chart is what type of data source?

Correct Answer: B

Rationale: A patient's chart is a secondary source compiled by others (e.g., past nurses' notes), not directly from the patient (primary). Tertiary sources (textbooks) or mixed classifications don't fit. Charts provide historical data e.g., prior vitals crucial for nursing continuity, per documentation standards.

Correct Answer: A

Rationale: Abdominal quadrants are examined RUQ, RLQ, LUQ, LLQ e.g., starting liver, appendix, spleen, colon for systematic coverage. Other orders lack this flow. Nurses use this e.g., in pain assessment for consistent, thorough evaluation, per clinical practice.

Correct Answer: B

Rationale: Dorothy Johnson's Behavioral System Model (1960s) views humans as systems with seven subsystems like attachment e.g., adjusting a child's feeding to stress. Orem emphasizes self-care, Henderson needs, and Parse becoming. Johnson's focus on behavioral equilibrium helps nurses address disruptions, like anxiety in hospitalization, influencing pediatric and psychiatric care assessments.

Correct Answer: A

Rationale: Callista Roy's Adaptation Model (1970s) frames humans as open systems, interacting with environments e.g., mood lifts with praise. Unlike Levin's conservation, Neuman's stressors, or Newman's expansion, Roy's focus on adaptation to stimuli like stress management guides nurses in dynamic, responsive care across settings.

Correct Answer: A

Rationale: Nursing care plans are nurse-centered designed to address patient needs e.g., managing pain. Rationales justify interventions (not vice versa), they're written, and goals vary (not fixed). This nurse-driven tool, per NANDA, ensures systematic, patient-focused care delivery.
