A Mother Brings Her 4-Month-Old Infant to the Clinic with Concerns

A mother brings her 4-month-old infant to the clinic with concerns regarding a small pad in the middle of the upper lip that has been there since 1 month of age. The infant has no health problems. On physical examination, the nurse notices a 0.5-cm, fleshy, elevated area in the middle of the upper lip. No evidence of inflammation or drainage is observed. What would the nurse tell this mother?

A) "This area of irritation is caused from teething and is nothing to worry about."
B) "This finding is abnormal and should be evaluated by another health care provider."
C) "This area of irritation is the result of chronic drooling and should resolve within the next month or two."
D) "This elevated area is a sucking tubercle caused from the friction of breastfeeding or bottle-feeding and is normal."
