What is a nasal cannula used for?

The correct answer is: A

A nasal cannula is a small plastic tube that is inserted into the nose, connected to an oxygen source and is used to deliver supplemental oxygen to patients who are experiencing respiratory issues. It is typically used for patients who only require a low flow of oxygen and can still breathe on their own. Options B, C, and D are incorrect because they do not pertain to the purpose of a nasal cannula. Option B, for example, is incorrect because a nasal cannula is not used for feeding or medication delivery. Similarly, option C is incorrect because a nasal cannula is not used for measuring blood pressure. Lastly, option D is incorrect because a nasal cannula is not used for bladder catheterization. Overall, the correct answer is A because it accurately describes the purpose of a nasal cannula.
