Introduction

Oxygen therapy is a crucial component of respiratory care, aimed at improving oxygenation and perfusion in clients with various respiratory conditions or inadequate oxygen levels.

The goal of oxygen therapy is to maintain adequate oxygen saturation in tissues and organs, ensuring proper cellular function and preventing hypoxia-related complications. Nurses play a vital role in assessing clients, administering oxygen, and monitoring their response to therapy.

Questions on Introduction

Correct Answer is D

Explanation

<p>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.</p>

Correct Answer is B

Explanation

<p>Adjusting the oxygen flow rate as needed is a valid action, but monitoring oxygen saturation levels is essential to guide the adjustment accurately.</p>

Correct Answer is C

Explanation

<p>Positioning the client in high Fowler&#39;s position facilitates lung expansion and may improve oxygenation but does not directly address airway clearance.</p>

<p>Ensuring an adequate supply of oxygen is a general consideration for all clients receiving oxygen therapy and is not specific to clients with COPD.</p>

<p>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.</p>
