Zorluk: ZorReduction of Risk Potential

A nurse is preparing to perform open-system tracheostomy tube suctioning for an adult client who is experiencing audible coarse crackles and a sudden decrease in oxygen saturation. To minimize the risk of mucosal trauma and hypoxemia, arrange the following procedural steps in the correct chronological sequence. All options must be used.

  1. 1Verify that the wall suction pressure is properly set between 100 and 120 mm Hg.
  2. 2Hyperoxygenate the client with 100% oxygen using a manual resuscitation bag or ventilator.
  3. 3Advance the sterile suction catheter into the airway without applying negative pressure.
  4. 4Withdraw the catheter approximately 1 to 2 cm (0.5 inches) upon encountering resistance.
  5. 5Apply continuous suction while rotating and withdrawing the catheter over no more than 10 to 15 seconds.
  6. 6Reassess the client's oxygen saturation and allow a recovery period before additional passes.

Cevap

The correct sequence ensures patient safety by prioritizing equipment preparation, pre-oxygenation, atraumatic insertion, proper positioning at the carina, safe suctioning limits, and physiological recovery.
Performing tracheostomy suctioning requires strict adherence to a specific chronological sequence to minimize the risks of hypoxemia, atelectasis, mucosal trauma, and infection. Validating a safe suction pressure (100-120 mm Hg) is the critical first step to ensure the equipment will not cause harm. Hyperoxygenation must immediately precede insertion to provide an oxygen reservoir for the client. The catheter is then inserted without suction to protect the mucosa, advanced until resistance is felt (indicating contact with the carina), and immediately withdrawn slightly (1-2 cm) to prevent mucosal invagination into the catheter tip. Suction is applied only during withdrawal, accompanied by a twisting motion, and strictly limited to 10-15 seconds to prevent profound hypoxemia. Finally, the client must be allowed to recover while being monitored before any subsequent passes are attempted.

Adım Adım Çözüm

1
Prepare and verify equipment parameters.
Wall suction is confirmed at a safe setting of 100 to 120 mm Hg for an adult.
Prevents tissue avulsion from excessive pressure and ensures functional clearance capacity.
2
Pre-oxygenate the client.
Client receives 100% oxygen prior to the procedure.
Compensates for the inevitable oxygen depletion that occurs when both air and secretions are suctioned from the airway.
3
Insert the catheter passively.
The sterile catheter is advanced down the tracheostomy tube without active suction.
Reduces friction and prevents adherence to the tracheal wall, avoiding mucosal stripping.
4
Position the catheter tip safely.
After meeting resistance at the carina, the catheter is pulled back 1 to 2 cm.
The carina is highly sensitive; direct suctioning on it causes severe trauma and can stimulate dangerous vagal bradycardia.
5
Apply active suction and remove.
Continuous suction is applied while twisting the catheter outward for 10 to 15 seconds max.
Twisting clears lateral secretions, while the strict time limit prevents profound atelectasis and hypoxia.
6
Evaluate and rest.
Vital signs and breath sounds are checked.
Determines the effectiveness of the intervention and allows the client to re-establish normal oxygenation.
