A client with severe hypoxemia requires oxygen therapy. What is the appropriate delivery method for this client?

Answer: d. Non-rebreather mask Explanation

A non-rebreather mask is the most suitable delivery method for a client with severe hypoxemia, as it provides the highest concentration of oxygen (up to 95%) by utilizing a reservoir bag and one-way valves to prevent the rebreathing of exhaled air.

Incorrect choices:

a. Nasal cannula delivers lower concentrations of oxygen and is more appropriate for clients with mild hypoxemia.

b. Simple face mask delivers moderate concentrations of oxygen and is suitable for clients with stable oxygen needs.

c. Venturi mask delivers precise concentrations of oxygen and is commonly used in clients with chronic respiratory conditions.

Answer: c. Encouraging deep breathing and coughing Explanation:

Deep breathing and coughing help to mobilize and clear respiratory secretions, promoting effective airway clearance and improved oxygenation.

Incorrect choices:

a. Incentive spirometry exercises help promote lung expansion but are not directly aimed at airway clearance.

b. Bronchodilator medications are primarily used to alleviate bronchospasm and improve airflow, but they may not directly address airway clearance.

d. Positioning the client in high Fowler's position facilitates lung expansion and may improve oxygenation but does not directly address airway clearance.
