The nurse preparing to admit a patient with emphysema to the medical-surgical unit has received a report from the emergency department that indicated the patient is receiving oxygen via a mask and has a pulse oximetry reading ranging from 93% to 94%
The nurse anticipates that the patient is receiving oxygen via which type of mask commonly used for patients with COPD?
A) A non-rebreathing mask
B) A Venturi mask
C) A simple mask
D) A partial-rebreathing mask
Ans: B
Feedback: A Venturi mask is the most reliable and accurate method for delivering precise concentrations of oxygen through noninvasive means. The Venturi mask is used primarily for patients with COPD because it can accurately provide an appropriate level of supplemental oxygen, thus avoiding the risk of suppressing the hypoxic drive. This type of mask is constructed in a way that allows a constant flow of room air blended with a fixed flow of oxygen.
