He preceptor is working with a new nurse to suction a patient through his new tracheostomy. which actions by the new nurse indicate need for additional teaching about the procedure? (select all that apply.)

The nurse should include the following tips when teaching about the suction:
1) Suction with clean technique
This is acceptable because the pathogens present in the home are far less than those in the hospital

2) Do not suction mouth the first
This can lead to disease causing agents going into the airway

3) Never recannulate the tube except in an emergency
