What device fits over the nose and mouth to deliver oxygen?

• A. Nasal Cannula
• B. Venturi Mask
• C. Face Mask
• D. Tracheostomy Tube

Answer: (C)

The device that fits over the nose and mouth to deliver oxygen is a face mask. A face mask is designed to cover both the nose and mouth, allowing for the efficient delivery of supplemental oxygen directly to the patient's airway. This method is particularly useful in various settings, including emergency care, where a patient may require a higher oxygen concentration than what can be achieved through other devices.

While a nasal cannula is another common oxygen delivery device, it specifically delivers oxygen through two small prongs inserted into the nostrils, which does not cover the mouth. A Venturi mask does fit over the nose and mouth but is specifically designed to deliver a precise concentration of oxygen using a system of colored adapters; it is not used for general oxygen delivery. A tracheostomy tube, on the other hand, is an artificial airway placed directly into the trachea and is not applicable for delivering oxygen in the same manner as a face mask.

Understanding the appropriate use and differences between these devices is crucial for effective patient management in respiratory care.
