Which intervention should the nurse prioritize to promote effective airway clearance in a client with impaired oxygenation?
Providing incentive spirometry exercises
Administering bronchodilator medications
Encouraging deep breathing and coughing
Positioning the client in high Fowler's position
The Correct Answer is C
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.

Correct Answer is D
Explanation
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.
Correct Answer is B
Explanation
Answer: b. 4-6 liters per minute
Explanation: The appropriate flow rate for oxygen therapy via a nasal cannula typically ranges from 1-6 liters per minute, with 4-6 liters per minute being a common range to achieve adequate oxygenation.
Incorrect choices:
a. 1-2 liters per minute may be appropriate for clients with mild hypoxemia or during rest.
c. 8-10 liters per minute is generally too high for a nasal cannula and may not be well-tolerated by the client.
d. 12-15 liters per minute is excessively high for a nasal cannula and may be more suitable for a higher flow oxygen delivery system such as a non-rebreather mask or Venturi mask.
