The pathogenesis of children’s common cold complicated with phlegm is

A. Delicacy of the lung

B. Congenital deficiency

C. Accumulation of milk and food

D. Dampness stagnating in the spleen and stomach

E. Deficiency of kidney qi

Answer analysis

Reference answer: A

Analysis: The lung of children is delicate and vulnerable to external pathogenic factors. When the lung collaterals fail to disperse properly and the qi movement is obstructed, body fluids are likely to condense and transform into phlegm. As a result, the phlegm blocks the airway, leading to an aggravated cough and the sound of phlegm in the throat, which is the common cold complicated with phlegm in children. Option A is correctly selected.
