Which statement is FALSE regarding orofacial masks?

• A. They never leak air
• B. They cover both the nose and the mouth
• C. Nasal pillows must fit snugly into each nostril
• D. They cover only the mouth

Answer: (C)

Orofacial masks are full-face interfaces designed to seal around both the nose and the mouth. Nasal pillows, on the other hand, belong to a nasal interface that fits into the nostrils. Because nasal pillows are not used with an orofacial (full-face) mask, the idea that nasal pillows must fit snugly into each nostril is not a characteristic of orofacial masks. That interface concept belongs to a different type of mask, not to the full-face design. In contrast, an orofacial mask does cover both the nose and the mouth, and while a proper fit helps minimize leaks, saying they never leak air isn’t accurate. It also isn’t correct to say they cover only the mouth, since the defining feature is sealing around both nose and mouth.
