Final answer:
The statement indicating an understanding of infectious mononucleosis is the parent recognizing the need for their child to rest and avoid contact sports. This reflects awareness of the disease's transmission, symptoms, and potential complications.
Step-by-step explanation:
The correct statement by a parent that indicates an understanding of the teaching about infectious mononucleosis is: "It's important for my child to rest and avoid contact sports for a while." This statement acknowledges the need for rest and recognizes that because of the potential for spleen enlargement and risk of rupture, contact sports should be avoided. The Sure-Vue Mono Test is used to detect the presence of the Epstein-Barr Virus (EBV), which is the most common cause of infectious mononucleosis, and resting is an essential part of the recovery.
Infectious mononucleosis is mainly spread through saliva, but blood and semen can also transmit the virus. Symptoms include pharyngitis, fever, fatigue, and lymph node swelling. Rest is crucial, not only to recover from the immediate symptoms but also to reduce the risk of complications such as spleen rupture, which can occur due to physical activity.
Sharing utensils can increase the risk of spreading the virus and long-lasting swollen lymph nodes can be a sign of complications and should be monitored. Therefore, the other options presented by the parents are incorrect with respect to managing and understanding infectious mononucleosis.
