A client with RSV is experiencing thick mucus and signs of airway obstruction. What medication class should the nurse anticipate administering?

A. Antibiotics to eliminate infection and improve airway clearance: Respiratory Syncytial Virus (RSV) is a viral pathogen, and antibiotics are ineffective against viruses. Using them without evidence of a secondary bacterial infection is inappropriate and does not assist in clearing thick mucus. The management of RSV is primarily supportive and focused on symptoms. B. Antitussives to suppress coughing and improve rest: Coughing is a vital protective mechanism for clearing the thick, obstructive mucus seen in RSV bronchiolitis. Suppressing the cough reflex can lead to worsening mucus plugging and increased respiratory distress. Antitussives are generally contraindicated in conditions characterized by heavy secretions. C. Decongestants to relieve nasal congestion and promote mucus clearance: Decongestants target upper airway edema but are not effective for the lower airway mucus production seen in RSV. They do not significantly thin thick secretions or improve the diameter of the bronchioles. Their role is limited in the management of pediatric bronchiolitis. D. Mucolytics to thin and loosen mucus: Mucolytic agents work by breaking down the chemical bonds in thick respiratory secretions to reduce their viscosity. This allows the patient to expectorate the mucus more easily, thereby improving airway patency and gas exchange. This class specifically addresses the mechanical obstruction caused by RSV.
