Pediatric ATI Practice Exam

A child is often excused from gym class after recovering from mononucleosis primarily due to the risk of abdominal trauma. Mononucleosis, commonly caused by the Epstein-Barr virus, leads to an enlargement of the spleen, which can occur in about 50% of cases. The spleen is a vital organ involved in filtering blood and immune function, but when enlarged, it becomes more susceptible to injury. Engaging in physical activities, particularly contact sports or vigorous exercise, raises the risk of splenic rupture, which can be a serious medical emergency.

This recommendation to avoid heavy exertion and contact sports helps prevent any potential complications associated with an enlarged spleen, ensuring the child's safety as they continue to recover from the illness.
