The nurse involved Mr. Gary's wife in his care plan. This is an example of?

Correct Answer: A

Rationale: Involving wife in plan is family-centered care (A) family inclusion, per definition. Patient-centered (B) patient focus, policy (C) rules, QI (D) enhancement not family-specific. A fits Mr. Gary's family role, 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.

Correct Answer: B

Rationale: The urea breath test detects *H. pylori* by measuring urease activity (CO2 output), offering high accuracy, low cost, and noninvasiveness. Stool antigen is accurate but less convenient, serology detects past exposure, and biopsy is invasive. Nurses favor this test for diagnosing ulcers, guiding antibiotic therapy, balancing efficacy and patient comfort.
