Infectious Mononucleosis (EBV): Diagnosis and Treatment Plan
This paper presents a clinical assessment of a 22-year-old patient exhibiting symptoms consistent with Epstein-Barr virus (EBV)-induced infectious mononucleosis (IM), including sore throat, fatigue, aching joints, fever, and swollen lymph nodes. Despite an initial negative Monospot test, the paper argues that early testing within the first week of symptoms likely produced a false negative result. The discussion covers expected clinical course, diagnostic follow-up using EBV serological testing, symptom management strategies including corticosteroids and OTC analgesics, patient education on hydration and rest, dietary recommendations for immune support, and precautions against rare complications such as splenic rupture.
- Clinical Presentation and Initial Findings: Symptoms, exam findings, and negative Monospot result

- Diagnostic Follow-Up and Testing Strategy: Repeat Monospot and EBV serological testing plan
- Treatment and Symptom Management: Corticosteroids, antibacterials, and supportive care
- Patient Education and Preventive Measures: OTC remedies, hydration, diet, and infection prevention
- Potential Complications and Activity Restrictions: Splenic rupture risk and activity avoidance guidance

What makes this paper effective
- Directly addresses the clinical significance of a false negative Monospot test by citing the timing of peak heterophile antibody levels, showing strong evidence-based reasoning.
- Integrates authoritative sources (CDC, peer-reviewed clinical journals) to support diagnostic and treatment decisions throughout.
- Balances clinical management with practical patient education, making the case study applicable to real-world family nurse practitioner (FNP) practice.
Key academic technique demonstrated
The paper demonstrates clinical reasoning under diagnostic uncertainty — acknowledging a negative lab result while constructing a well-supported argument for a working diagnosis based on symptom timing, epidemiology, and the known limitations of the Monospot test. This is a model of evidence-based diagnostic thinking commonly expected at the graduate nursing or advanced practice level.
Structure breakdown
The paper opens with symptom presentation and a rationale for the suspected diagnosis, then moves through diagnostic follow-up planning, treatment (pharmacological and supportive), patient education, and complication prevention. Each section builds logically on the previous one, following a standard SOAP-adjacent clinical case format appropriate for graduate-level health sciences writing.
Clinical Presentation and Initial Findings
The symptoms presented by the patient are consistent with infectious mononucleosis (IM) caused by Epstein-Barr virus (EBV). These include symptoms that appear to mimic those of the flu. In addition to a sore throat, the patient complains of aching joints and fatigue. An elevated temperature and swollen lymph nodes were also revealed following an initial examination by the FNP. The lab results were, however, unremarkable, and a Monospot test returned a negative result.
It is important to note that "because peak heterophile antibody levels are seen between 2 to 6 weeks from infection, testing too early in the disease process may lead to increased rates of false negative testing" (Stuempfig & Seroy, 2019). In this case, the patient has been experiencing flu-like symptoms for only one week. Therefore, the Monospot test may have been undertaken too early, which would account for the negative result.
Diagnosis: Infectious Mononucleosis Caused by EBV
Infectious mononucleosis is, according to Dunmire, Hugguist, and Balfour (2015), "characterized by sore throat, cervical lymph node enlargement, fatigue and fever" (p. 219). As the authors further point out, in cases of lymph node enlargement, there is often equal enlargement of anterior and posterior cervical nodes. Age is also an important consideration. Although IM can occur at any age, it has a higher rate of occurrence among teenagers. IM has been commonly referred to as the "kissing disease" due to the fact that one key mode of transmission is through saliva.
According to Balfour, Dunmire, and Hogguist (2015), the Epstein-Barr virus is responsible for the vast majority of all infectious mononucleosis cases. On the basis of the findings and discussion above, the expected diagnosis in the present case is therefore infectious mononucleosis caused by EBV. This diagnosis forms the basis for the patient's clinical course and treatment options.
Diagnostic Follow-Up and Testing Strategy
Given that the Monospot test was initially negative, a repeat test should be scheduled one week later. If results remain persistently negative for three consecutive weeks, a specific EBV serological test should be ordered. It is important to note that EBV, as the Centers for Disease Control and Prevention (CDC, 2018) observes, belongs to the herpes virus family. As the CDC further notes, this virus is quite common — meaning that most people will encounter it at some point in their lives. Apart from saliva, EBV can also be transmitted through other body fluids, including blood and semen. At present, no vaccine has been developed to protect against IM; however, IM is rarely fatal.
Treatment and Symptom Management
IM does not have a specific treatment, much like the common cold. Because it is a viral infection, antibiotics would largely be ineffective. However, an individual with IM may be susceptible to secondary bacterial infections. The primary focus of management should therefore be on resolving the symptoms presented by the patient. For instance, to reduce tonsil swelling and clear the sore throat, corticosteroid medication may be prescribed. Antibacterial medications are effective in the resolution of tonsil, strep, and sinus infections when a secondary bacterial infection is identified.
The symptoms associated with IM would be expected to resolve within one to two months. To ensure full resolution of all symptoms and to monitor for any complications, close follow-up is recommended. A follow-up appointment in one month is appropriate, and the patient should be advised to return sooner if symptoms worsen.
