Which of the following statement is TRUE about pulse?

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: 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.

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.
