A nurse is caring for a client receiving oxygen therapy via a nasal cannula. What is an important complication associated with prolonged use of a nasal cannula?

Answer: c. Placing padding between the mask and the client's skin.

Explanation: Placing padding between the oxygen mask and the client's skin helps distribute pressure and reduce the risk of pressure ulcers. It provides a cushioning effect and helps prevent direct contact between the mask and the skin.

Incorrect choices: a. Frequently adjusting the mask to relieve pressure may disrupt the proper fit and seal of the mask, leading to ineffective oxygen delivery.

b. Applying petroleum jelly to the areas of skin contact is not recommended as it may interfere with the mask's fit and compromise oxygen delivery.

d. Assessing the client's facial skin integrity regularly is important but does not directly address the prevention of pressure ulcers. Placing padding is a proactive measure to prevent skin breakdown.

Answer: c. Providing frequent oral care to prevent dry mouth.

Explanation: NPPV devices, such as continuous positive airway pressure (CPAP) or bilevel positive airway pressure (BiPAP), can cause dry mouth. Providing frequent oral care, such as mouth rinses and moisturizing agents, helps alleviate discomfort and prevent oral complications.

Incorrect choices: a. Assessing the client's oxygen saturation every 4 hours is not specific to NPPV therapy and does not address the unique nursing intervention required for this intervention.

b. Monitoring the client's respiratory rate every 15 minutes may not be necessary for all clients receiving NPPV therapy and should be based on the client's condition and healthcare provider's orders.

d. Administering oxygen at a flow rate of 1-2 L/min is not appropriate for NPPV therapy, which delivers a higher flow of pressurized air to support ventilation.
