The nurse notes that the client diagnosed with emphysema becomes restless and confused. Which action, if taken by the nurse, is BEST?
1. Encourage the client to perform pursed-lip breathing.
CORRECT- prevents collapse of lung unit, and helps client control rate and depth of breathing
2. Check the client’s temperature.
Incorrect- confusion is probably due to decreased oxygenation
3. Assess the client’s potassium level.
Incorrect- confusion is probably due to decreased oxygenation, not electrolyte imbalance
4. Increase the client’s oxygen flow rate to 5 L/min.
Incorrect- should receive low-flow oxygen to prevent CO2 narcosis
