NCLEX RN Practice Question

Administering oxygen via a non-rebreather mask is the most appropriate initial intervention for a client with severe respiratory distress and SpO₂ of 83%. This device delivers a high concentration of oxygen rapidly, which is critical to stabilizing the client. High Fowler's position can improve breathing mechanics, but it is insufficient alone for such low oxygen saturation. Suctioning should only be attempted if there are clear signs of secretion buildup obstructing the airway, and in this case, there is no evidence of obstruction. Encouraging deep breathing exercises is helpful in mild respiratory difficulty but would not adequately address an SpO₂ of 83%, which is life-threatening.
