Correct Answer: A

Rationale: When a client reports headache and vertigo after turning on the furnace for the first time, it suggests carbon monoxide poisoning. Carbon monoxide is an odorless, colorless gas that can be released by malfunctioning heating systems. Symptoms of carbon monoxide poisoning include headache, dizziness, weakness, nausea, and confusion. It is crucial for the nurse to suspect this condition promptly to ensure the client's safety and well-being.

Correct Answer: B

Rationale: When a client has burns involving the face, ears, and eyelids, the priority finding to report to the provider is difficulty swallowing. This symptom could indicate potential airway compromise or swelling in the throat, which can lead to serious complications. Monitoring and addressing this issue promptly is crucial to ensure the client's airway remains patent and secure.

Correct Answer: D

Rationale: Confusion is a common finding in older adult clients with pneumonia, often indicating hypoxia. Hypertension, unequal pupils, and tympany upon chest percussion are not typically associated with community-acquired pneumonia in older adults.

Correct Answer: B

Rationale: In a client with chronic bronchitis, the nurse or healthcare provider would expect to hear resonant sounds upon percussion. Resonance is the normal percussion sound heard over healthy lung tissue. The other options such as dullness, tympany, and flatness are associated with different conditions or abnormalities, not typically expected in chronic bronchitis.

Correct Answer: D

Rationale: In COPD, pursed-lip breathing helps improve breathing efficiency by maintaining positive pressure in the airways, preventing airway collapse, and promoting oxygenation. This technique assists in controlling respiratory rate, reducing dyspnea, and enhancing oxygen saturation levels. Restricting fluid intake is not typically a part of COPD management. Providing a low-protein diet is not a standard intervention for COPD. Early-morning hours are generally not recommended for exercise due to cooler temperatures and higher pollution levels, which can exacerbate COPD symptoms.
