Which of the following conditions is an example of hyperbilirubinemia?

Hyperbilirubinemia refers to an abnormally high level of bilirubin in the blood. Bilirubin is a yellow pigment formed during the breakdown of red blood cells, and its proper levels in the body are crucial for health. When bile production is excessive, it can lead to an increased breakdown of red blood cells and consequently elevate bilirubin levels. In conditions where the liver is functioning properly, an appropriate amount of bile can facilitate the processing and excretion of bilirubin. However, excessive bile production can overwhelm this process, leading to hyperbilirubinemia.

The other options do not align with the definition of hyperbilirubinemia. Low bile production would likely lead to decreased bilirubin processing, normal bilirubin levels indicate that there is no hyperbilirubinemia present, and low red blood cell counts can also contribute to lower bilirubin levels, thus not qualifying as hyperbilirubinemia.
