Conceptualized the BEHAVIORAL SYSTEM MODEL

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: 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.

Correct Answer: D

Rationale: Pulse pressure is systolic minus diastolic e.g., 120-80 = 40 mmHg showing arterial elasticity. Apical (heartbeats), cardiac (synonym), and pulse deficit (apex-radial gap) differ. Nurses calculate this e.g., hypertension for cardiovascular health, per hemodynamics.

Correct Answer: B

Rationale: The stethoscope bell auscultates low-frequency Korotkoff sounds e.g., tapping unlike diaphragm (high). Pulse +4 (bounding), +1 (weak), sound pitch (low) differ. Nurses use this e.g., bell for clarity, per technique.

Correct Answer: D

Rationale: Sugar isn't normal in urine e.g., glucosuria signals diabetes unlike urea (waste), sodium, potassium (electrolytes). Nurses test e.g., dipstick for abnormalities, per physiology.
