The most critical factor in the care of an infant after repair of a cleft lip is–

Correct option is B

Sol. After cleft lip surgery, maintaining a patent airway is the highest priority, especially in infants who are obligate nose breathers. Postoperative swelling, bleeding, or secretions can compromise breathing. Ensuring airway patency with proper positioning and suctioning is essential to prevent respiratory distress.
Explanation of each option:
· (a) Prevent vomiting – Important to reduce pressure on sutures, but not the topmost priority. Airway compromise is more immediately life-threatening.
· (b) Maintaining a patent airway – Correct Answer. Vital in postoperative care. Infants must be closely observed for noisy breathing or cyanosis.
· (c) Maintaining parenteral fluid infusions – Important for hydration, but airway obstruction takes precedence in acute care settings.
· (d) Administering medications that reduce oral secretions – May help, but not all infants require this, and it is not the most critical step.
