The nurse used a study to choose Mr. Gary's treatment. This is an example of?

Correct Answer: A

Rationale: Using a study for treatment is evidence-based practice (A) research-guided, per definition. Learning (B) growth, disparity (C) inequity, coordination (D) organization not research-specific. A fits the nurse's evidence use for Mr. Gary, making it correct.

Correct Answer: B

Rationale: Leadership is guiding care delivery (B), per nursing e.g., directing Mr. Gary's team. Not following (A), not task (C), not clerical (D) direction-based. B best defines leadership's role, enhancing care, making it correct.

Correct Answer: B

Rationale: POS plans combine HMO and PPO (B), per definition e.g., referrals plus flexibility for Mr. Gary. Referrals needed (A), not emergency-only (C), not all (D) hybrid model. B truly defines POS's structure, making it correct.

Correct Answer: C

Rationale: The transtheoretical model outlines behavior change stages: precontemplation (unaware of need), contemplation (considering change), preparation, action, and maintenance. 'Perceived benefit' aligns with the Health Belief Model, not this framework, which focuses on readiness, not perceived outcomes. 'Peraptation' seems a typo, possibly meaning preparation, but isn't listed. Nurses use this model to tailor interventions, like motivational interviewing in contemplation, supporting patients through change processes effectively.

Correct Answer: D

Rationale: Hypokalemia (low potassium) impairs intestinal motility, causing abdominal distention from gas or ileus. Edema relates to fluid imbalance, muscle spasms to hypocalcemia, and Kussmaul breathing to acidosis not potassium. Nurses assess for distention, weakness, or arrhythmias, correcting levels to restore gastrointestinal and muscular function, vital for patient stability.
