This assignment addresses a case study involving a 4-year-old child presenting with symptoms of an acute upper respiratory infection, including ear pain, sneezing, cough, and fever. The solution begins with a diagnosis of an acute upper respiratory viral infection and probable ear infection. It then details the pathophysiology of the condition, explaining that the symptoms are indicative of an acute viral infection. The assignment then discusses both pharmacologic and non-pharmacologic interventions. Pharmacologic interventions include antihistamines, paracetamol, dextromethorphan, and amoxicillin, with detailed explanations of their pharmacokinetics and pharmacodynamics. Non-pharmacologic interventions such as analgesic ear drops, warm compress, honey, and probiotics are recommended. The assignment provides evidence-based support for each intervention, citing relevant research articles. Finally, a summarized plan is presented for the parents and child, including dosages and reasons for administration, combining both prescriptive and non-prescriptive approaches.
