Streptococcal Pharyngitis - Nursing Case Study
Pathophysiology
• Primary mechanism: Streptococcal pharyngitis is primarily caused by the bacterium Streptococcus pyogenes. This pathogen adheres to the epithelial cells in the throat, initiating an inflammatory response. The bacteria produce toxins and enzymes that damage tissues, causing sore throat, redness, and swelling.
• Secondary mechanism: The infection triggers an immune response, leading to the recruitment of white blood cells to the site of infection. This immune activity contributes to symptoms like pain and fever as the body attempts to eliminate the bacteria.
• Key complication: If untreated, streptococcal pharyngitis can lead to minor complications such as sinusitis or otitis media, where the infection spreads to the sinuses or middle ear, causing further inflammation and discomfort.

Initial Assessment Findings:
Upon further assessment, the patient, a 25-year-old female elementary school teacher, presents with mild erythema and swelling of the tonsils, accompanied by white exudates, which are classic signs of streptococcal pharyngitis. Palpation of the neck reveals slight tenderness and enlargement of the anterior cervical lymph nodes, indicative of lymphadenopathy. Despite these findings, she remains alert and oriented, with no respiratory distress or difficulty swallowing. Her oral mucosa is moist, and she maintains adequate hydration, though she reports mild discomfort when swallowing solid foods.
Her vital signs remain stable, with a temperature of 99.2°F, heart rate at 76 bpm, blood pressure at 118/72 mmHg, respiratory rate of 16 breaths per minute, and SpO2 at 98% on room air. Given her stable condition, the immediate nursing focus is on symptom management and educating the patient about the importance of completing any prescribed antibiotic regimen to prevent potential complications, such as sinusitis or otitis media. The patient is advised to increase her fluid intake, rest as much as possible, and use over-the-counter analgesics for pain relief, pending further evaluation by a healthcare provider.
This initial assessment lays the foundation for subsequent diagnostic work, such as a rapid antigen detection test (RADT) or throat culture, to confirm the presence of Group A Streptococcus and guide appropriate antibiotic therapy. The nursing team will continue to monitor her symptoms and vital signs closely, ready to intervene if her condition changes or if more severe symptoms develop.

Following the initial assessment and the initiation of supportive care measures, the patient underwent a rapid antigen detection test (RADT) for Group A Streptococcus, which returned a positive result. This confirmed the diagnosis of streptococcal pharyngitis. The healthcare provider prescribed a 10-day course of oral penicillin V, a standard treatment to eradicate the infection and prevent complications. The nursing team reinforced the importance of adhering to the prescribed antibiotic regimen, emphasizing that completing the full course is crucial even if symptoms improve, to prevent recurrence and resistance.
Two days into the antibiotic treatment, the patient reports a noticeable reduction in throat pain and improved ability to swallow, indicating a positive response to the intervention. Her vital signs continue to remain stable, with her temperature decreasing to 98.6°F. Her appetite has improved, and she is able to consume soft foods without significant discomfort. The tenderness and swelling of the cervical lymph nodes have also diminished slightly, suggesting a favorable response to the antibiotics.
The nursing team continues to provide supportive care, ensuring the patient remains well-hydrated and rests adequately. They also educate her on recognizing signs of potential complications, such as ear pain, nasal congestion, or persistent fever, which would necessitate further medical evaluation. As the patient progresses, the focus remains on monitoring for any new symptoms and reinforcing health education to support her recovery and prevent transmission of the infection to others in her workplace.
Section 3
Three days into the antibiotic treatment, the nursing team notices a slight change in the patient's status during a routine assessment. While the patient continues to report an overall improvement in symptoms, she expresses mild discomfort in her left ear, which has developed since the previous day. Upon examination, the nurse observes that the patient's left tympanic membrane is slightly erythematous, suggesting the possibility of developing otitis media, a minor complication sometimes associated with streptococcal infections.
Vital signs remain stable, with the patient's temperature holding at 98.8°F, blood pressure at 118/76 mmHg, and heart rate at 76 beats per minute. The patient's throat continues to show improvement with reduced erythema and swelling, and her cervical lymph nodes are less tender upon palpation. Given the new symptom of ear discomfort, the nursing team communicates this finding to the healthcare provider, who orders an otoscopic examination to further evaluate the condition of the ear and determine the appropriate course of action.
The nursing team takes this opportunity to reinforce education about the importance of completing the antibiotic course and maintaining hydration. They also discuss the relevance of promptly reporting new symptoms and provide reassurance that the ear discomfort is being appropriately addressed. The patient is advised to monitor for any increase in ear pain or the development of other symptoms such as dizziness or hearing loss, which would require immediate attention. This new aspect of her care plan emphasizes the importance of vigilance in monitoring for complications while continuing to support her recovery from streptococcal pharyngitis.

Two days later, the patient completes the prescribed course of antibiotics, and the nursing team conducts a follow-up assessment to evaluate her progress. The patient reports feeling significantly better overall, with her sore throat nearly resolved and no further fever episodes. However, she mentions persistent mild discomfort in her left ear, though it has not worsened. During the otoscopic examination, the healthcare provider notes that while the erythema of the left tympanic membrane has slightly diminished, there is still some residual fluid behind the membrane, indicating serous otitis media.
The patient's vital signs remain stable, with a temperature of 98.6°F, blood pressure of 116/74 mmHg, and heart rate of 74 beats per minute. Her throat shows no signs of new erythema or swelling, and the cervical lymph nodes are non-tender. The healthcare provider decides to manage the serous otitis media conservatively, given its mild nature and the patient's stable condition, advising continued observation and symptomatic treatment with analgesics as needed.
The nursing team reinforces educational points regarding ear care and advises the patient to avoid any activities that may worsen the ear condition, such as swimming or exposure to extreme altitude changes. The emphasis is placed on the importance of reporting any new symptoms such as increased ear pain, hearing changes, or balance issues. Encouraged by her recovery trajectory, the patient is reassured that her condition is improving, and the team plans for a follow-up appointment to ensure complete resolution of symptoms. This approach highlights the importance of comprehensive care and ongoing assessment in managing minor complications effectively.
Section 5
Two weeks after the initial follow-up, the patient returns for her scheduled appointment. She reports that her sore throat has completely resolved, and she has been free of fever. However, she now experiences intermittent mild pressure in her left ear, particularly noticeable when lying down or during rapid changes in position. She denies any significant ear pain, hearing loss, or balance disturbances. These symptoms prompt further evaluation to ensure there is no progression of her otitis media.
During the physical examination, her vital signs remain within normal limits: temperature is 98.5°F, blood pressure is 118/76 mmHg, and heart rate is 72 beats per minute. An otoscopic examination reveals that the erythema of the left tympanic membrane has resolved, but there is still a small amount of serous fluid present. The tympanic membrane is intact, and there are no signs of acute infection. Based on these findings, the healthcare provider recommends a continuation of conservative management, emphasizing the importance of adequate hydration and the use of analgesics to alleviate any discomfort.
As the patient has shown improvement and there are no significant new complications, the nursing team takes this opportunity to reinforce self-care strategies. They advise the patient on the importance of avoiding upper respiratory irritants, such as tobacco smoke, and encourage gentle techniques to equalize ear pressure, like yawning or swallowing during pressure changes. The patient is instructed to monitor her symptoms and report any new developments, such as increased ear discomfort or signs of infection, to ensure prompt intervention if necessary. With a care plan focused on observation and symptom management, the patient's condition is expected to continue improving, leading to a complete resolution of symptoms in the coming weeks.
