A nurse is assessing a client receiving oxygen therapy via a non-rebreather mask. What should the nurse do to ensure the mask is functioning effectively?
Ensure the reservoir bag is fully deflated during inhalation.
Adjust the oxygen flow rate to the highest setting.
Inflate the reservoir bag prior to inhalation.
Remove the one-way valve from the mask.
The Correct Answer is C
Answer: c. Inflate the reservoir bag prior to inhalation.
Explanation: The reservoir bag of a non-rebreather mask should be inflated to ensure an adequate oxygen supply during inhalation. The inflated bag provides a reservoir of oxygen-rich air that is delivered during each breath.
Incorrect choices:
a. Ensuring the reservoir bag is fully deflated during inhalation would limit the amount of oxygen available for the client.
b. Adjusting the oxygen flow rate to the highest setting may lead to excessive oxygen concentrations and is not necessary for effective mask functioning.
d. Removing the one-way valve from the mask would compromise the integrity of the non-rebreather system and prevent effective oxygen delivery.

Correct Answer is D
Explanation
Answer: d. Administering humidified oxygen through the cannula
Explanation: Humidified oxygen should be administered through a nasal cannula to prevent drying of the nasal passages and promote client comfort. It is important for the nurse to ensure the oxygen is properly humidified to prevent mucosal irritation.
Incorrect choices:
a. Securing the cannula tightly around the client's head may cause discomfort and impede circulation.
b. Placing the cannula in the client's mouth is not the correct placement for a nasal cannula.
c. Assessing the client's skin behind the ears for pressure ulcers is important when using devices that apply pressure, such as oxygen masks or headgear, but not specific to the nasal cannula.
Correct Answer is C
Explanation
c. The nurse should closely monitor the client for signs of oxygen toxicity, such as substernal pain, respiratory distress, and changes in mental status.
Incorrect choices:
a. Ensuring the catheter is placed in the client's nostrils is incorrect as a transtracheal catheter is inserted directly into the trachea, bypassing the nose.
b. Assessing the client's respiratory rate every 15 minutes is too frequent for routine assessment and may disrupt the client's care.
d. While teaching coughing and deep breathing techniques can be important for clients with respiratory issues, it is not the most immediate or critical nursing consideration for clients using a transtracheal catheter.
