The nurse is educating an adolescent and their parents on the diagnosis of Mononucleosis. What patient education would the nurse provide to the adolescent and their parents?

A. It occurs from a streptococcal viral infection is incorrect because infectious mononucleosis is caused by the Epstein–Barr virus (EBV), which is a viral infection spread through saliva. Streptococcus refers to a bacterial organism, most commonly associated with strep throat, and is not the cause of mononucleosis. Understanding the viral origin is important because it explains why antibiotics are not effective. B. Cervical lymphadenopathy is present is correct. One of the most common and characteristic findings in mononucleosis is enlarged, tender cervical lymph nodes, especially in the posterior cervical chain. This occurs as a result of the immune system responding to the EBV infection. Teaching families to expect swollen lymph nodes helps reduce anxiety and improves understanding of the disease course. C. You need to take the full course of antibiotics is incorrect because antibiotics do not treat viral infections. Mononucleosis is managed with supportive care, including rest, hydration, antipyretics, and pain relief. Additionally, administration of antibiotics such as amoxicillin or ampicillin in patients with mono can cause a diffuse maculopapular rash, which is an important teaching point for patients and families. D. If contracted you need to stay home from school is incorrect because routine exclusion from school is not required. Mononucleosis is not spread by casual contact, and students may attend school as tolerated based on fatigue level. However, adolescents should be instructed to avoid contact sports or strenuous activity for several weeks due to the risk of splenic enlargement and potential splenic rupture, which is a critical safety concern.
