An adolescent boy is admitted to the emergency department (ED) following a bee sting. He arrives with a body rash and 30 minutes later he becomes short of breath. The nurse obtains vital signs with a blood pressure of 90/52 mm Hg, heart rate 130 beats/minute, and respiratory rate 40 breaths/minute. The client is exhibiting clinical manifestations of which type of immune reaction?

Choice A reason: Amber urine may indicate dehydration or bilirubin excretion but is less specific than yellow sclera for common bile duct obstruction. Bilirubin buildup from a lodged gallstone causes jaundice, and sclera changes are a more direct sign, making this less urgent to report.

Choice B reason: Yellow sclera indicates jaundice from bile duct obstruction, as a lodged gallstone blocks bilirubin excretion, elevating serum levels. This causes nausea and vomiting, signaling a serious complication requiring urgent intervention, making it the most critical finding to report.

Choice C reason: Belching is non-specific and common in gastrointestinal issues, not directly indicating bile duct obstruction. Jaundice from bilirubin buildup is a more severe sign of gallstone complications, making belching less urgent to report compared to yellow sclera.

Choice D reason: Flatulence reflects gastrointestinal motility but is not specific to bile duct obstruction. Yellow sclera directly indicates bilirubin accumulation from a blocked duct, a serious issue causing nausea, making flatulence a less critical finding to report to the provider.

Choice A reason: Daily use of tiotropium via its handihaler is correct, as this long-acting anticholinergic bronchodilator is administered once daily for COPD maintenance. It relaxes airway smooth muscles, improving airflow, and consistent use prevents exacerbations, indicating proper understanding of the medication’s administration schedule.

Choice B reason: Using tiotropium for sudden shortness of breath is incorrect, as it is not a rescue inhaler. Tiotropium provides sustained bronchodilation over 24 hours, not rapid relief. Short-acting beta-agonists like albuterol are used for acute symptoms, indicating a need for further teaching.

Choice C reason: Using another inhaler between tiotropium doses suggests misunderstanding, as tiotropium is a once-daily maintenance therapy. Additional inhalers may be prescribed, but this statement implies incorrect timing or overuse, which could lead to improper COPD management, requiring clarification.

Choice D reason: Expecting thinner sputum is incorrect, as tiotropium does not affect mucus viscosity. It dilates airways, not liquefying secretions, which is the role of mucolytics. This misunderstanding indicates a need for teaching about tiotropium’s bronchodilatory, not mucolytic, effects in COPD.
