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

Correct Answer: D

Rationale: 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.

Correct Answer: C

Rationale: CPAP mask provides positive pressure throughout the respiratory cycle, including expiration, and is effective in delivering the necessary PEEP in clients with ARDS.

Correct Answer: D

Rationale: When using a face mask for oxygen therapy, the nurse should assess the client's skin for any signs of irritation or breakdown due to prolonged mask use. It is important to ensure proper mask fit and periodically assess the skin integrity to prevent pressure ulcers or skin breakdown.

Correct Answer: B

Rationale: 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.

Correct Answer: C

Rationale: Oxygen supports combustion, and using electric heating devices in the presence of oxygen therapy can pose a significant fire hazard. It is important to educate clients with long-term oxygen therapy about the importance of avoiding open flames and electric heating devices to ensure their safety.
