Zorluk: OrtaReduction of Risk Potential

A 68-year-old client with a history of severe chronic obstructive pulmonary disease (COPD) and a recent tracheostomy requires open airway suctioning. The client exhibits audible coarse crackles, restlessness, and an oxygen saturation drop to 88%. To mitigate the risk of physiological decompensation during the procedure, arrange the following nursing actions in the correct chronological sequence from first to last.

  1. 1Verify the wall suction pressure is set between 80 and 120 mm Hg.
  2. 2Hyperoxygenate the client with 100% oxygen.
  3. 3Advance the catheter into the tracheostomy tube without applying suction.
  4. 4Apply intermittent suction while rotating and withdrawing the catheter.
  5. 5Flush the catheter with sterile saline and reassess the client's respiratory status.

Cevap

The correct sequence for open airway suctioning prioritizes equipment safety, physiological preparation, atraumatic insertion, limited active suctioning, and post-procedure evaluation: First, verify the wall suction pressure; second, hyperoxygenate the client; third, advance the catheter without suction; fourth, apply intermittent suction during withdrawal; and fifth, flush the catheter and reassess.
The physiological priority during open tracheostomy suctioning is maintaining oxygenation and preventing tissue trauma. The nurse must first ensure equipment safety by checking the suction pressure (80 to 120 mm Hg). Next, hyperoxygenation is crucial to build up oxygen reserves. The catheter is then advanced without suction to avoid depleting oxygen or damaging the airway during entry. Once inserted to the proper depth, intermittent suction is applied only during withdrawal to clear secretions safely. Finally, clearing the line with sterile saline and reassessing the client ensures the procedure was effective and the client has stabilized.

Adım Adım Çözüm

1
Verify the wall suction pressure is set between 80 and 120 mm Hg.
Safe negative pressure limits are established before the procedure begins.
Excessive suction pressure can cause significant trauma to the tracheal mucosa and induce bleeding, while insufficient pressure will not clear thick secretions.
2
Hyperoxygenate the client with 100% oxygen.
The client's functional residual capacity of oxygen is maximized.
Suctioning inevitably removes oxygen from the airway along with secretions. Pre-oxygenating prevents severe procedure-induced hypoxemia and resulting dysrhythmias.
3
Advance the catheter into the tracheostomy tube without applying suction.
The catheter is placed safely down to the level of the carina.
Applying active suction during insertion strips oxygen from the airway unnecessarily and significantly increases the risk of the catheter adhering to and tearing the mucosal wall.
4
Apply intermittent suction while rotating and withdrawing the catheter.
Secretions are effectively cleared from the airway.
Rotating the catheter cleans all surfaces of the airway, and limiting active suction to the withdrawal phase for no more than 10 to 15 seconds minimizes hypoxia and tissue damage.
5
Flush the catheter with sterile saline and reassess the client's respiratory status.
The tubing is cleared of thick mucus, and the efficacy of the intervention is thoroughly evaluated.
Flushing prevents catheter occlusion for subsequent passes. Reassessing lung sounds and oxygen saturation determines if further suctioning is required or if the client has returned to baseline.
