A nurse is caring for a client with the diagnosis of emphysema, a chronic obstructive pulmonary disease (COPD). The client is hypoxemic and also has chronic hypercarbia. Which statement reflects the oxygen needs of this client?1.The client may need up to 60% oxygen flow via Venturi mask.2.The client requires lower levels of oxygen delivery, usually 1 to 3 L/min via nasal cannula.3.The client should receive humidified oxygen delivered by a face mask.4.The client's respiratory treatment plan should have oxygen eliminated from it

1. The client may need up to 60% oxygen flow via Venturi mask

Explanation:

Emphysema is a lung condition that causes shortness of breath due to over inflation of the air sac in the lung, while someone who is hypoxemic has low level of oxygen in the blood and also an hypercabia person has elevated carbon-1.dioxide level in the body. Considering all of this conditions, it will be safe to say that the client is short of breath, low in oxygen with an elevated carbon-dioxide which is not safe so the best thing to do is to deliver oxygen concentration of about that percentage through venturi mask to the client.
