Correct Answer: C

Rationale: Failed to generate a rationale of 500+ characters after 5 retries.

Correct Answer: C

Rationale: Ernestine Wiedenbach's Clinical Nursing A Helping Art Model, from the 1960s, frames nursing as an art aiding patients' needs e.g., teaching a diabetic self-injection. Swanson's caring, Hall's core-care-cure, and Zderad's humanistic focus differ. Wiedenbach's practical, patient-centered approach, with its ‘clinical' emphasis, guides nurses in purposeful interventions, impacting training and bedside care.

Correct Answer: B

Rationale: A closed system, per systems theory, is isolated e.g., a candle dies under a glass from no oxygen input. Unlike open systems (Roy's humans), it doesn't allow matter, energy, or information exchange, making it a ‘sole island.' This contrasts with nursing's open-system patient care, highlighting environmental influence.

Correct Answer: A

Rationale: Gordon's Functional Health Patterns (1980s) assess stressors' impact on mind, body, and environment re: ADLs e.g., mobility post-stroke. Unlike head-to-toe (physical order), body systems (organ-based), or cephalocaudal (top-down), it's holistic, guiding nurses in comprehensive, function-focused care planning.

Correct Answer: B

Rationale: Pulsus paradoxus is an exaggerated systolic drop (>10 mmHg) on inspiration e.g., in pericardial effusion due to heart compression. Other options misalign: increase (opposite), or positional pulse (unrelated). Nurses detect this e.g., via sphygmomanometer for cardiac emergencies, per pathophysiology.
