Where should the nasal cannula be placed during oxygen delivery?

• A. Place the cannula in the patient's mouth.
• B. Place the tips of the nasal cannula into the patient's nostrils and wrap the tubing behind the ears.
• C. Tape the cannula to the forehead for stability.
• D. Leave the cannula dangling outside the nose.

Answer: (B)

Nasal cannula delivery relies on placing the prongs in the nostrils and securing the tubing behind the ears. This position delivers oxygen directly through the nasal passages and keeps the tubing in place during movement, preventing dislodgement and ensuring the prescribed flow reaches the lungs efficiently. Placing the cannula in the mouth would not deliver oxygen effectively and could cause discomfort. Taping to the forehead isn’t the standard securement and can irritate the skin, while leaving the cannula dangling outside the nose risks it becoming dislodged and reducing the delivered flow.
