The nurse has just initiated oxygen by nasal cannula for a client with the medical diagnosis of chronic obstructive pulmonary disease. What is the nurse's next action?
1. Fill the humidifier with normal saline.
2. Pad the tubing where it contacts the client's ears.
3. Set the oxygen delivery to 5 liters.
4. Secure the cannula with ties around the client's head.
Correct Answer: 2
Rationale 1: The humidifier should be filled with water prior to initiating therapy.
Rationale 2: It is necessary to pad the cannula where it contacts the client's ears as pressure irritation may occur.
Rationale 3: Since this client has chronic obstructive pulmonary disease, the oxygen should be set at a lower delivery rate (generally no more than 1.5 to 2 Lpm).
Rationale 4: The cannula does not require ties to secure.
