The nurse is caring for a client with a history of hypertension. Which lifestyle modification should the nurse emphasize?

Choice A reason: Huff coughing clears airway secretions but is less urgent than assessing oxygenation in acute dyspnea. COPD exacerbations reduce oxygen saturation, risking hypoxia. Pulse oximetry confirms the severity, guiding interventions, as coughing techniques are secondary to ensuring adequate oxygenation.

Choice B reason: Humidification prevents airway drying during oxygen therapy but does not address immediate dyspnea or hypoxia. Pulse oximetry is prioritized to assess oxygenation status in COPD exacerbation, as low oxygen levels require urgent intervention, making humidification a secondary consideration.

Choice C reason: Nebulizer treatments, like albuterol, relieve bronchospasm but require confirmation of hypoxia severity. Pulse oximetry assesses oxygen saturation, guiding whether nebulization or oxygen is needed. In acute COPD exacerbation, oxygenation status is critical to prioritize before administering treatments.

Choice D reason: Pulse oximetry measures oxygen saturation, critical in COPD exacerbation with dyspnea and tachypnea. Low saturation indicates hypoxia, guiding oxygen therapy or bronchodilator use. This objective data is the next priority after positioning, as it directs immediate interventions to prevent respiratory failure.

Choice A reason: Palpating for joint warmth and swelling is the best technique for early rheumatoid arthritis, as it detects synovitis, a hallmark of the disease. Inflamed joints are warm, swollen, and tender due to autoimmune-driven synovial proliferation, enabling early identification and intervention to prevent joint damage.

Choice B reason: Measuring range of motion assesses joint function but is less specific for early rheumatoid arthritis. Reduced motion occurs later, after significant synovial inflammation or damage. Palpating for warmth and swelling directly identifies active synovitis, making it more effective for early detection.

Choice C reason: Assessing grip strength evaluates muscle and joint function but is nonspecific for early rheumatoid arthritis. Weakness may result from pain or later joint damage. Palpating for warmth and swelling targets synovial inflammation, the earliest sign, making it the preferred technique for early diagnosis.

Choice D reason: Observing gait and posture detects functional limitations but is not specific for early rheumatoid arthritis. Gait changes occur with advanced disease or other conditions. Palpating for joint warmth and swelling directly identifies synovial inflammation, the primary early feature, making it more diagnostic.
