Which action indicates correct suctioning technique for a client with a tracheostomy?

The action of withdrawing the suction catheter 1 to 2 cm before applying suction reflects correct suctioning technique for a client with a tracheostomy. This practice is crucial because it helps prevent trauma to the tracheal mucosa. When suction is applied, it is important to avoid suctioning for too long or too closely to the tracheostomy site, as this can cause irritation, bleeding, or damage to the trachea.

Proper technique involves ensuring that the catheter is positioned safely within the airway, allowing for effective clearance of secretions while minimizing the risk of injury. Withdrawing slightly before suctioning creates a space that helps avoid the negative effects of direct suctioning on sensitive tissues.

Different choices presented highlight techniques that could potentially lead to complications. For instance, using a catheter size that may be too large for the patient's airway could cause obstruction or trauma. Using high pressure when suctioning is detrimental, as excessive pressure can damage lung tissue or create a risk of hypoxemia. Lastly, applying suction for an extended period, like 25 seconds, is generally beyond the recommended duration, as prolonged suctioning can lead to hypoxia and other adverse effects. Therefore, withdrawing the catheter appropriately before suctioning is an essential part of safe
