Choice B rationale
Mild discomfort may be associated with an umbilical hernia, but it is not typically a cause for immediate concern or a reason to alert the healthcare provider.
Choice C rationale
A bulge that disappears when lying down is a common characteristic of an umbilical hernia and is not typically a cause for immediate concern or a reason to alert the healthcare provider.

Nausea and vomiting could indicate that the hernia has become strangulated, which is a medical emergency. Strangulation occurs when the blood supply to the herniated tissue is cut off. This is a serious complication that requires immediate medical attention.
