The nurse is caring for a client receiving oxygen therapy via a Venturi mask. Which assessment finding indicates the need for adjustment of the oxygen flow rate?

Answer: c. "Avoid using electric heating devices in your home."

Explanation: Oxygen supports combustion, and using electric heating devices in the presence of oxygen therapy can pose a significant fire hazard. It is important to educate clients with long-term oxygen therapy about the importance of avoiding open flames and electric heating devices to ensure their safety.

Incorrect choices: a. Ensuring a fire extinguisher is readily available is a good general safety practice but may not directly address the specific risk associated with oxygen therapy.

b. Keeping the oxygen tubing loose may increase the risk of tangling and accidental disconnection. The tubing should be appropriately secured and free from obstructions.

d. Using an oxygen concentrator for outdoor activities may not be necessary for all clients and should be based on individual needs and healthcare provider recommendations.

Answer: c. Client reporting nasal dryness and discomfort.

Explanation: The client reporting nasal dryness and discomfort indicates inadequate humidification of the oxygen. The nurse should assess and adjust the oxygen flow rate or consider providing humidified oxygen to alleviate the client's discomfort.

Incorrect choices: a. An oxygen saturation of 98% indicates adequate oxygenation and does not necessitate an adjustment in the oxygen flow rate.

b. A respiratory rate of 16 breaths per minute within the normal range does not indicate a need for adjustment of the oxygen flow rate.

d. An oxygen flow rate set at 4 L/min may be appropriate for a Venturi mask, depending on the prescribed oxygen concentration and the client's needs.
