Incorrect Answer:
The correct answer is: Encouraging pursed-lip breathing exercises
Rationale:
A. Administering 2 liters of oxygen via nasal cannula: While supplemental oxygen may be necessary, it should be carefully titrated in COPD patients to avoid suppressing their drive to breathe. Therefore, it's not always the first or only intervention.
B. Encouraging pursed-lip breathing exercises: Pursed-lip breathing helps to keep the airways open longer, allowing more air to escape and improving ventilation and oxygenation. This technique is particularly useful during an acute exacerbation of COPD.
C. Administering a bronchodilator as prescribed: While bronchodilators are essential in managing COPD exacerbations, the immediate intervention to improve oxygenation would be encouraging effective breathing techniques like pursed-lip breathing.
D. Placing the patient in a supine position: This position can worsen dyspnea in COPD patients by limiting lung expansion. Instead, sitting upright or in a semi-Fowler's position is recommended to facilitate better breathing.
