A nurse is reviewing the medical record for a child who is scheduled to receive a varicella immunization. Which of the following findings in the client's record should the nurse recognize as a contraindication?

A. Clear rhinorrhea. Mild respiratory illnesses, such as a common cold with clear nasal discharge, do not contraindicate varicella vaccination. The immunization can still be administered unless the child has a moderate to severe illness with fever. B. Medications for a cardiac anomaly. Having a congenital heart defect or taking cardiac medications does not typically contraindicate varicella vaccination. However, children on high-dose immunosuppressive therapy for heart conditions may need further evaluation before receiving live vaccines. C. Chemotherapy treatments. Chemotherapy suppresses the immune system, increasing the risk of severe complications from live vaccines like varicella. Children undergoing chemotherapy should not receive live-virus vaccines until immune function has sufficiently recovered, as determined by a healthcare provider. D. Two diarrhea stools in the last day. Mild, self-limiting diarrhea does not contraindicate vaccination. Only children with severe acute gastrointestinal illness should have vaccinations postponed until they recover.
