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. 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.

Answer: b. "I will secure the oxygen tubing under furniture legs."

Explanation: Securing the oxygen tubing under furniture legs can create a potential safety hazard by causing the tubing to become twisted or pulled, disrupting the oxygen flow. It is important to educate the client about keeping the tubing free from obstructions and ensuring it is positioned safely.

Incorrect choices: a. "I should avoid smoking while using oxygen" is a correct statement, as smoking near oxygen can be extremely dangerous and increase the risk of fire.

c. "I will keep the oxygen equipment away from open flames" is a correct statement, as oxygen supports combustion and can cause a fire if exposed to open flames.

d. "I will use a water-based moisturizer for dry nasal passages" is a correct statement, as oxygen therapy can cause dryness in the nasal passages, and using a water-based moisturizer can help alleviate discomfort.
