A nurse is caring for a client receiving oxygen therapy via a mask. What is an important nursing intervention to prevent pressure ulcers on the client's face?

Answer: b. Adjusting the oxygen flow rate as prescribed.

Explanation: The nurse should adjust the oxygen flow rate on the Venturi mask according to the prescribed percentage of inspired oxygen (FiO2). The specific flow rate and FiO2 will be specified in the healthcare provider's orders.

Incorrect choices: a. Monitoring the client's oxygen saturation continuously may not be necessary for all clients receiving oxygen therapy via a Venturi mask. The frequency of oxygen saturation monitoring should be based on the client's condition and healthcare provider's orders.

c. Assessing the client's lung sounds every shift is a general nursing assessment and may not be directly related to the use of a Venturi mask.

d. Placing the mask loosely over the client's face may compromise the delivery of the precise FiO2 and should be avoided. The mask should be properly secured to ensure accurate oxygen administration.

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.
