A nurse is performing tracheostomy care for a client. What action should the nurse take?

Explanation:

Performing tracheostomy care and suctioning to remove copious secretions is a critical procedure in nursing. The nurse should take several steps to ensure that this is done correctly and safely. The best action in this scenario would be the option C. Lubricate suction catheter tip with sterile saline. This is crucial for two reasons: first, the lubrication means that there will be less discomfort and potential damage to the tracheostomy site. Secondly, the use of sterile saline is important for maintaining a clean and infection-free environment. Applying suction multiple times can be harmful and cause trauma to the patient's trachea. Also, hyperventilating a patient on 100% oxygen can risk causing oxygen toxicity. Chest physiotherapy is usually performed after suctioning to help clear mucus or secretions from the lungs, not before.
