Answer:
B. Mental status
Step-by-step explanation:
Respiratory diseases are medical conditions that affect the lungs and breathing capacity, but do not alter the child's mental state, so in assessing the child's breathing, it will not be necessary to evaluate breathing work, chest expansion and sounds of the child's breath. It is not necessary to evaluate the mental states to know if the child has breathing problems.
Some breathing problems are genetic while others are caused by lifestyle or environmental factors. Common breathing problems include asthma, bronchitis, emphysema, tuberculosis and sinusitis.
