Rationale: To maintain the sterility of the procedure, it is crucial to teach the client the correct technique for drawing medication from a vial.

Rationale: When the catheter of the suctioning device attaches to the tracheal walls, causing a pulling sensation, the nurse should release the suction by opening the vent. This action will alleviate the pulling sensation and prevent trauma to the delicate tracheal walls. Continuing suctioning or applying more pressure can lead to tissue damage and should be avoided. Suctioning deeper can increase the risk of injuring the patient's airway.
