A nurse working in a long-term care facility is assessing residents at risk for the development of a pressure injury. Which resident would be most at risk?

Correct Answer: A

Rationale: Age, walker use, incontinence, and cardiac history increase risk most. Comatose (C) is high-risk, but A’s factors are more extensive.

Correct Answer: C

Rationale: Normal inspiration involves the diaphragm and intercostal muscles expanding the chest, allowing elastic recoil of lung tissue to facilitate air intake. This is a mechanical process, not a chemical receptor response, oxygen saturation drop, or CO2 binding issue.

Correct Answer: A

Rationale: Pneumonia causes airway inflammation and consolidation, obstructing air flow and impairing oxygenation more directly than fluid overload, heart rate, or blood pressure.

Correct Answer: B

Rationale: Atelectasis (lung collapse) improves with coughing to re-expand alveoli and clear secretions, enhancing oxygenation, unlike diuretics, ice packs, or fluid restriction.

Correct Answer: A

Rationale: Tachypnea (rapid breathing) is a compensatory mechanism to increase oxygen intake in hypoxia, unlike bradycardia, hypotension, or lethargy, which suggest decompensation.
