When performing an assessment on a school-aged child, the nurse notes that the mucous membranes along the gum margins have a noticeable blue-colored line. At this point, the nurse should ask the parents about possible:
A) Liver problems as an infant
B) Congenital heart problems
C) Exposure to lead
D) Second-hand smoke exposure
Ans: C
Feedback:
The formation of a blue lead line along the margins of the gum is one of the diagnostic features of lead poisoning. Liver problems are usually displayed as jaundice (yellowing of the skin/sclera). Congenital heart problems may exhibit cyanosis, but this would not be just in the gum margins. Second-hand smoke exposure may cause accumulation in the lungs.
