A nurse is caring for a 3-year-old toddler who was newly admitted with pertussis in stage 2 (the paroxysmal stage) of the illness. Which of the following interventions should the nurse perform first?

A. Monitor intake and output: Monitoring hydration is important in children with pertussis due to vomiting after coughing spells, but it is not the immediate priority in the paroxysmal stage. Stabilizing the child and minimizing triggers that worsen coughing takes precedence. B. Provide a nutritious meal: During the paroxysmal stage, coughing fits can be severe and are often followed by vomiting. Offering meals too early may increase the risk of emesis and aspiration rather than support recovery. C. Request play activities from the play therapist: Excessive stimulation, including play, can precipitate coughing paroxysms in pertussis. Activity should be limited during acute episodes to reduce respiratory distress. D. Allow the child to sleep and take a nap: Rest and reduced stimulation are priorities during the paroxysmal stage of pertussis. Sleep helps conserve energy, decreases coughing triggers, and supports respiratory stability during this critical phase.
