A nurse is attending a social gathering when another guest suddenly coughs weakly once, grasps her throat with her hands, and cannot talk. Which of the following actions should the nurse take?

A) Cleanse the mask or collar with soapy water every other day. The mask or collar should be cleansed at least once daily to prevent bacterial growth and maintain hygiene.
B) Post "no smoking" warning signs at home in a prominent location. This is essential to reduce the risk of fire hazards associated with oxygen therapy.
C) Make sure the straps on the mask are secure but not too tight. Properly adjusted straps ensure a secure fit without causing skin breakdown or discomfort.
D) Check the tops of his ears regularly for skin breakdown. Prolonged use of oxygen masks can cause pressure injuries on the ears, making regular checks necessary.
E) Apply petroleum jelly around and inside the nares. Petroleum-based products are flammable and should be avoided. Water-based moisturizers are safer alternatives.

A. Continue to monitor the client: A rise in the water seal with inspiration and fall during expiration (tidaling) is normal in a functioning chest tube system and indicates proper lung expansion.
B. Clamp the chest tube near the water seal: Clamping the tube can cause tension pneumothorax and is not appropriate unless specifically instructed by a provider.
C. Reposition the client and recheck the chamber: Repositioning is unnecessary unless there are signs of obstruction or complications.
D. Add water to the chamber: Water addition is only required if the water level falls below the recommended amount, not in response to normal tidaling.
