Final answer:
Some early signs of impending airway obstruction in a child with LTB include respiratory symptoms such as shortness of breath, wheezing, and hoarseness.
Step-by-step explanation:
Some early signs of impending airway obstruction in a child with LTB (Laryngotracheobronchitis) include: Respiratory symptoms such as shortness of breath, wheezes or stridor (a high-pitched sound when breathing), hoarseness, pain with swallowing, and cough. Other signs may include temperature instability, apnea (cessation of breathing), bradycardia (slow heart rate), hypotension, difficulty feeding, irritability, and limpness.
As the condition progresses, symptoms of late-onset disease may manifest, including seizures, bulging fontanel (soft spot), stiff neck, weakness on one side of the body, and a rigid body with an arched back and head thrown backward. Therefore some early signs of impending airway obstruction in a child with LTB include respiratory symptoms such as shortness of breath, wheezing, and hoarseness. Other signs may include temperature instability, apnea, bradycardia, hypotension, difficulty feeding, irritability, and limpness.
