She described the four conservation principle.

Correct Answer: A

Rationale: Myra Levine's Conservation Model, from the 1960s, outlines four principles energy, structural integrity, personal integrity, social integrity to maintain wholeness. For example, conserving energy in a fatigued patient via rest preserves function. Unlike Leininger's cultural care, Orlando's interaction focus, or Parse's existential lens, Levine's principles guide nurses to protect patient unity, influencing holistic care strategies in clinical settings.

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: Younger people have higher pulse rates e.g., 80-100 bpm vs. 60-80 in adults due to faster metabolism. Males post-puberty have lower rates (strength), digitalis slows (negative chronotropic), and lying lowers pulse (rest). Nurses note this e.g., pediatric norms per physiology.

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.
