A nurse is planning care for a client with pharyngitis caused by a viral infection. Which nursing intervention is most appropriate?

A. Provide steroid therapy for immediate relief of symptoms: Glucocorticoids are typically reserved for severe inflammatory compromise or airway obstruction in specific conditions like mononucleosis. They are not the standard first-line intervention for a self-limiting viral pharyngitis in an immunocompetent patient. Routine use of steroids for mild viral infections carries unnecessary risks of systemic side effects. B. Administer antibiotics to alleviate throat pain: Antibiotics target bacterial cell walls or metabolic pathways and have zero efficacy against viral pathogens. Prescribing them for a viral etiology contributes to the global crisis of antimicrobial resistance and provides no clinical benefit to the patient. Pain management should instead focus on analgesics or topical soothing agents. C. Recommend usage of antihistamines to reduce inflammation: Antihistamines are indicated for Type 1 hypersensitivity reactions by blocking H1 receptors to reduce allergic rhinitis or urticaria. They do not address the inflammatory cascade triggered by a viral infection of the oropharynx. Their drying effect may actually increase throat irritation by reducing protective mucosal lubrication. D. Encourage hydration and rest: Supportive care is the primary management strategy for viral infections to allow the immune system to clear the pathogen. Oral fluids maintain mucosal moisture and prevent dehydration, while rest conserves metabolic energy for the immune response. This intervention aligns with evidence-based protocols for non-complicated viral pharyngitis.
