Correct Answer is D
Explanation
A) Endotracheal tube. An endotracheal tube is invasive and used for patients who require mechanical ventilation, not for simple airway maintenance.
B) Partial rebreather oxygen mask. A partial rebreather mask is used to deliver oxygen, not to maintain airway patency.
C) Tracheostomy. A tracheostomy is a surgical procedure for long-term airway management and is unnecessary in this scenario.
D) Pharyngeal airway. A pharyngeal airway helps maintain airway patency by preventing the tongue from obstructing the airway.
Correct Answer is B,C,D,G,E,F,A
Explanation
Check the function of the suction catheter: Ensures the catheter is functioning properly before starting the procedure.
Don sterile gloves: Maintains asepsis during the suctioning procedure.
Adjust the suction to 120 to 150 mm Hg: Proper suction pressure prevents mucosal trauma.
Hyperoxygenate the client: Prevents hypoxia during the suctioning process.
Insert the catheter without suction: Prevents trauma to mucosa by reducing suction on insertion.
Apply intermittent suction while rotating the catheter: Effectively clears secretions while minimizing tissue damage.
Check for secretion clearance: Ensures the airway is clear and the procedure was effective.
