True
False

The Correct Answer is B

D. Burns can be severe even if they cover a small area, especially if they affect critical regions like the face, hands, feet, or perineum, or if they are deep (e.g., full-thickness burns).
Correct Answer is C
Explanation
A. Infection prevention is managed through sterile technique and proper tracheostomy care, not by using a one-way valve cap.
B. A one-way valve cap does not deliver oxygen; in fact, it requires that the patient be able to breathe through their upper airway.
C. The purpose of a one-way valve cap (such as a Passy-Muir valve) is to facilitate speech by allowing air to enter through the tracheostomy but forcing exhaled air through the vocal cords and upper airway, enabling phonation and improved communication.
D. Suctioning is performed through the tracheostomy tube, but the one-way valve cap is not designed to assist in that process.
