What immediate action should be taken for a 77-year-old female with a productive cough and cyanosis?

In the case of a 77-year-old female exhibiting a productive cough and cyanosis, the most appropriate immediate action is to administer oxygen by a non-rebreather mask. This choice is correct because cyanosis indicates a lack of adequate oxygen perfusion in the body, which might stem from respiratory distress or a significant underlying medical condition. The non-rebreather mask is designed to deliver a high concentration of oxygen, which is crucial for quickly addressing hypoxia and improving the patient's oxygen saturation levels.

Using a non-rebreather mask allows for a greater flow of oxygen to be administered than other standard methods, effectively enhancing oxygen availability for the patient who is showing signs of respiratory compromise. Immediate and adequate oxygenation is vital for stabilizing the patient's condition and preventing potential further complications associated with low oxygen levels.

Other options would not provide the immediate and effective oxygenation that this patient requires. Assisting with ventilation using a BVM is an important intervention but might be more appropriate if the patient is unable to maintain their own airway or is showing severe respiratory failure. Rapid transport could be necessary eventually, but immediate oxygenation should take precedence. Increasing the oxygen flow rate to 4 L/minute may not be sufficient to address the severe degree of hypoxia suggested by
