A person facing eminent death may cry often, become socially withdrawn, or become mute. This may be indicative of

Correct Answer: D

Rationale: These symptoms align with depression in Kübler-Ross’s stages of grief, where individuals facing death may exhibit sadness (crying), withdrawal, and reduced communication. Isolation is a cause or result, not a stage; bargaining involves negotiation, and anger manifests as frustration, not withdrawal.

Correct Answer: B

Rationale: Constant changes in healthcare and nursing activities make it challenging to pin down a static definition, as nursing evolves with new roles, technologies, and practices.

Correct Answer: C

Rationale: Preferred provider organizations allow patients greater choice of providers, medications, and medical devices within a designated list, offering more flexibility than HMOs or integrated networks.

Correct Answer: C

Rationale: The respiratory rate of 26 breaths/min (normal 12-20) is significantly elevated, consistent with pneumonia’s impact on breathing (e.g., tachypnea due to reduced lung function). This requires immediate attention to assess oxygenation and potential respiratory distress. HR 102 is elevated but expected with fever and infection; temperature 37.9°C is a mild fever; pulse pressure (48 mm Hg) is within normal range (40-60 mm Hg).

Correct Answer: B

Rationale: A loose cuff fails to adequately compress the artery, requiring more pressure to occlude it, resulting in falsely high blood pressure readings (B). Pulse pressure may increase slightly (A), low readings (C) occur with a tight cuff, and no change (D) is incorrect as fit affects accuracy.
