Question 1 :

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

A. Nasal cannulaB. Simple face maskC. Venturi maskD. Non-rebreather mask

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.
