ASSESSMENT: Primary Diagnosis: The patient’s clinical symptoms suggest an Infectious Mononucleosis also called mono or Kissing disease. Epstein- Barr virus (EBV) is the most common cause of infectious mononucleosis. On physical examination of the patient’s neck, the posterior cervical lymph nodes are swollen, and the Tonsillo-pharyngeal area erythematous with exudate. Infectious mononucleosis is common among teenagers and young adults, especially college students. The disease spreads through bodily fluids, especially saliva but can also spread through blood, semen or organ transplantations. It’s incubation period is between 4-8 weeks with symptoms after the first 3 days of exposure. Most common symptoms include; fever, sore throat, swollen lymph nodes in the neck and arm pits, fatigue, swollen liver or spleen or both which the patient and his girlfriend are both experiencing. Management of IM is usually supportive and can be ruled out by doing a peripheral smear looking for the presence of atypical lymphocytes and doing a heterophile antibody test (Luzuriaga & Sullivan, 2010).
1. Gilbert syndrome: Gilbert’s syndrome, the liver doesn’t properly process bilirubin which is produced by the breakdown of red blood cells. Thereby causing the skin and the whites of the eyes to have a yellowish tinge (jaundice), which is as a result of the slightly elevated levels of bilirubin in the blood (Domino, Baldor, & Golding, 2015). This can be ruled out by doing CBC and liver function test. A combination of normal blood and liver function tests and elevated bilirubin levels is an indicator of Gilbert’s syndrome. Genetic testing usually confirms the diagnosis. (Luzuriaga & Sullivan, 2010).
2. Hepatitis C is a viral infection that causes liver inflammation, sometimes leading to serious liver damage. The hepatitis C virus (HCV) spreads through contaminated blood and can cause both acute and chronic hepatitis. The acute process is self-limited, rarely causes hepatic failure and usually leads to chronic infection. However, the chronic HCV infection often follows a progressive course over many years which can ultimately result in cirrhosis, hepatocellular carcinoma, and the need for liver transplantation (William & Hopper 2011).
PLAN: Diagnostic: Liver Function Test (LFT), Complete Blood Count (CBC), Comprehensive Metabolic Panel (CMP) Hepatitis Panel, Ultrasound, Rapid Strep Test/Throat Culture, Monospot test. SCREENING: None Medical treatment (Rx): The treatment is supportive. Patients are encouraged to rest during the acute phase but can resume activity when fever, pharyngitis, and malaise abate. To prevent splenic rupture, patients should avoid heavy lifting and contact sports for 1 month after presentation and until splenomegaly (which can be monitored by ultrasonography) resolves.
EDUCATION/HOME REMEDIES: There is no vaccine to protect against mononucleosis. To prevent the of disease, people should avoid kissing or sharing drinks or personal items with people who have the disease. Contact sport should be avoided since the liver or spleen may be swollen which may cause rupture. Inform the patient that signs and symptoms of infection include fever, chills, sore throat, enlarged lymph nodes, and fatigue. Emphasize the importance of self-care while the disease runs its course, which includes adequate fluid and nutritional intake along with sufficient rest. Patient is encouraged/instructed to use (over the counter) OTC ibuprofen or Tylenol to reduce fever. (Kormos, W. 2014).
CONSULT/REFERRAL: Patient to consult provider if fluctuant fever or new symptoms appear such as nausea, vomiting, abdominal pain, neck stiffness, swollen testicles, skin rash, increased fatigue, cough or shortness of breath. (Rana, R. S., & Moonis, G. 2015).
FOLLOW-UP: In the event of worsening symptoms or onset of new symptoms, patient is advised to seek medical assistance immediately.
