Final answer:
The patient's symptoms and physical examination findings are suggestive of acute otitis media (AOM). Visualization of the tympanic membrane is the most sensitive diagnostic test. Treatment may include antibiotics, analgesics, and close follow-up.
Step-by-step explanation:
The patient's symptoms of fever, tugging on the right ear, and a red and bulging tympanic membrane are suggestive of acute otitis media (AOM). AOM is an infection of the middle ear that commonly occurs in children between 3 months and 3 years of age.
The most sensitive diagnostic test for AOM is visualization of the tympanic membrane using otoscopy. The red and bulging appearance of the tympanic membrane confirms the diagnosis.
The recommended treatment for AOM depends on the severity of symptoms. Antibiotics are commonly prescribed for severe cases or when the patient is younger than 6 months. Analgesics and antipyretics, such as acetaminophen or ibuprofen, can also be used to alleviate pain and fever. Close follow-up is important to ensure resolution of symptoms and monitor for complications.
