Answer:
1. The client may need up to 60% oxygen flow via Venturi mask
Step-by-step 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.
