Final answer:
A nasal cannula is the appropriate oxygen delivery method for a patient prescribed to receive 2 L/min of oxygen, being suitable for flow rates of 1 to 6 L/min and allowing for more comfort and mobility for the patient. Option A.
Step-by-step explanation:
The appropriate oxygen delivery method for a patient prescribed to receive 2 L/min of oxygen is the nasal cannula. A nasal cannula is a device that delivers low concentrations of oxygen and is suitable for patients who require a minor increase in oxygen concentration. It's typically used for flow rates of 1 to 6 L/min. Other methods, such as a simple face mask, Venturi mask, or non-rebreather mask, are designed for higher oxygen delivery concentrations or specific clinical situations.
A nasal cannula consists of a lightweight tube with two prongs that are inserted into the nostrils. It is a comfortable choice for patients who are ambulatory and require long-term oxygen therapy at low flow rates. This method allows patients to eat, talk, and drink with greater ease compared to masks that cover the nose and mouth.
