Scenario
A college student presented to the campus health clinic with a two-day history of fever and sore throat. She was concerned about the severity of her symptoms because she had experienced infectious mononucleosis at age 15 and remembered similar throat pain. Further testing should be planned to determine the underlying cause and guide treatment.
Diagnosis
The primary diagnosis for the patient is Group A Streptococcal pharyngitis, as indicated by ICD-10 code J02.0 (WHO, 2023). The diagnosis was made based on the patient’s symptoms of fever and sore throat, along with a positive rapid strep test result. The primary resource for this diagnosis includes the patient’s laboratory results, physical examination, and medical history.
Differential Diagnoses
Differential diagnoses include pharyngitis caused by a viral infection (J02.9), which shares similar symptoms such as sore throat and fever but can be differentiated by a negative rapid strep test (WHO, 2023). Resources for this differential diagnosis will include the patient’s history, physical examination, and a negative rapid strep test result.
Another differential diagnosis is influenza, identified by ICD-10 code J10.1, which can present with symptoms similar to those of strep throat, including fever, sore throat, and general malaise (WHO, 2023). Confirming or ruling out influenza will require a specific influenza test, the results of which are essential for this differential diagnosis.
Peritonsillar abscess, coded J36, is another differential diagnosis, as this condition can present with fever and a sore throat (WHO, 2023). An ultrasound or CT scan can be a valuable resource for this diagnosis, as they can visualize an abscess if one is present.
The prescribed medication is Amoxicillin 500mg, taken orally twice daily for ten days, as it is effective against Streptococcus and is the first-line therapy for strep throat (Mustafa & Ghaffari, 2020). Over-the-counter Acetaminophen will be used for symptomatic relief of fever and pain, and the patient should not exceed 4 grams in 24 hours (Van Driel et al., 2021).
Diagnostic Tests
Ancillary tests for Mono and Influenza have been ordered, considering her history and the current symptoms. Referrals to an ENT specialist will be needed if symptoms persist or if a peritonsillar abscess is suspected.
Social determinants, such as living in a college dormitory, have contributed to the patient’s illness through close contact with others. Health promotion activities should include education on hand hygiene and on avoiding the sharing of drinks or utensils. A follow-up appointment has been scheduled within one week to evaluate the response to treatment.
A throat culture will be warranted for confirmatory diagnosis, even if a rapid strep test is positive. A complete blood count (CBC) can help rule out infections such as mononucleosis, for which the patient has a history. A flu test can help rule out influenza as a differential diagnosis, especially during flu season (Van Driel et al., 2021). If symptoms worsen or persist, imaging such as a CT scan will be required to assess for complications such as a peritonsillar abscess.
Consults
Should symptoms persist after treatment, a referral to an Ear, Nose, and Throat (ENT) specialist might be necessary for further evaluation. Given her college student status, consultation with a mental health counselor can be beneficial to help manage potential stressors that can impact her health (Luo et al., 2019). If the peritonsillar abscess is suspected, an immediate referral to the emergency department (ER) is recommended for possible drainage or surgery. An appointment with an infectious disease specialist might be necessary if the fever persists despite antibiotic therapy to rule out atypical infections.
Therapeutic Modalities
The primary therapeutic modality is pharmacological, with Amoxicillin 500mg administered orally twice daily for 10 days to eliminate Group A Streptococcus bacteria (Mustafa & Ghaffari, 2020). For symptomatic relief of fever and pain, over-the-counter Acetaminophen will be employed, with careful attention to not exceed a total of 4 grams within 24 hours (Van Driel et al., 2021). Non-pharmacological management includes ensuring adequate hydration and rest to support the body’s recovery process. Additional therapeutic measures include warm saltwater gargles or lozenges to soothe the throat and ease discomfort associated with the condition.
Health Promotion
As part of a holistic health promotion strategy, patients should be encouraged to practice rigorous hand hygiene to help prevent the spread of infectious pathogens. Avoiding sharing drinks or eating utensils with others is another important preventive measure, given the contagious nature of strep throat. Regular immunizations, particularly against influenza, are recommended to prevent potential causes of sore throat and overall enhance immune resilience (Van Driel et al., 2021). The patient should be educated on the importance of maintaining a balanced diet and proper sleep patterns to support overall health and recovery.
Patient Education
The patient must understand the importance of completing the full course of antibiotics, even if there are early improvements. The patient should be educated to recognize signs of complications, such as difficulty swallowing or breathing, which require immediate medical attention (Mustafa & Ghaffari, 2020). The patient must understand how to prevent spreading the infection to others, which includes practicing proper handwashing and covering their mouth when coughing or sneezing.
Disposition/Follow-up Instructions
The patient has been scheduled for a follow-up appointment within one week to assess the response to treatment. If symptoms worsen or fail to improve within 48-72 hours, the patient should seek immediate medical attention (Van Driel et al., 2021). Any suspected complications, such as a peritonsillar abscess, necessitate an urgent visit to the ER.
