Which description matches Nasal Cannula (NC)?

Which description matches Nasal Cannula (NC)?

• A. A plastic tube placed into the patient's nostrils.
• B. A facial mask with reservoir bag attached.
• C. A large facial mask with Ambu-bag
• D. A mask fit over nose and mouth

Answer: (A)

The main idea is recognizing how a nasal oxygen device is arranged and used. A nasal cannula is a thin, flexible plastic tube with two small prongs that sit inside the patient’s nostrils to deliver oxygen directly into the nasal passages. This design is distinct from masks, which cover the nose and mouth and may include a reservoir bag or a bag-valve device. So the description of a plastic tube placed into the nostrils best matches a nasal cannula. It’s typically used for low-to-moderate oxygen needs and allows the patient to breathe normally, speak, or eat while receiving oxygen.
