Final answer:
When clearing infant secretions, suction the mouth before the nose to prevent mucus inhalation into the lungs. The cilia in the nasal passages effectively filter out particles and pathogens, making mouth suctioning a priority for a newborn.
Step-by-step explanation:
When clearing infant secretions, it's recommended to suction the mouth before the nose. This is because infants are primarily nasal breathers, and suctioning the mouth first prevents the potential inhalation of mucus into the lungs should they gasp while the nose is being cleared. Additionally, the anatomy of the nasal passages, with cilia and mucus that trap pathogens, makes them more effective in filtering out particles. This means that it's important to deal with secretions in the mouth first to ensure that the nasal passages remain clear for the infant to breathe effectively.
Upon the birth of a newborn, medical practitioners often perform suctioning to clear secretions from the mouth and nose. This procedure is critical before the newborn's first breath to prevent aspiration of mucus into the lungs. By understanding the function of the nasal cavity and pharynx as well as the cilia’s role in pushing mucus out of the body, healthcare providers can ensure the safety and health of the newborn during this process.
