Question

A client with a severe exacerbation of COPD requires reliable and precise oxygen delivery. Which mask will the nurse expect the health care provider to prescribe?

a) Non-rebreather air mask b) Tracheostomy collar
c) Venturi mask
d) Face tent

Answer 1

For precise oxygen delivery in COPD exacerbation, a Venturi mask is likely to be prescribed because it delivers a specific concentration of oxygen by mixing it with room air, providing controlled oxygen therapy.

Step-by-step explanation:

The question relates to the provision of oxygen therapy for a client with a severe exacerbation of COPD (Chronic Obstructive Pulmonary Disease). For reliable and precise oxygen delivery, the health care provider is likely to prescribe a Venturi mask. This mask is designed to deliver a specific concentration of oxygen by mixing oxygen with room air. A Venturi mask is particularly useful for patients requiring controlled oxygen therapy, such as those with COPD.

The alternative options mentioned include a non-rebreather mask, which provides the highest concentration of oxygen but does not allow for precise control of oxygen delivery. A tracheostomy collar is for patients with a tracheostomy, and a face tent is used when a mask is not tolerated, usually providing humidified air or oxygen.

Therefore, the Venturi mask is the appropriate choice for a client needing controlled and precise oxygen levels, as it can accommodate the need for specific oxygen concentration and flow rates, helping to avoid the risk of carbon dioxide retention that COPD patients are susceptible to.
