Acute Laryngotracheobronchitis (Croup): NCLEX Nursing Guide

Acute Laryngotracheobronchitis (LTB), commonly known as croup, is a viral infection that affects the upper airway, leading to inflammation of the larynx, trachea, and bronchi. It is a high-yield NCLEX topic, especially in pediatric nursing, as it commonly affects children under age 5 and can progress to severe respiratory distress if not properly managed.
