Bradley is a 5 year old with a history of moderate asthma who was started on oral steroids yesterday after visiting his pediatrician for an asthma exacerbation.  In addition, he has been receiving aerosol treatments every 4 hours since yesterday.  He received his last levalbuterol nebulizer treatment 3 hours ago.  His mother has brought him back to the office because she is concerned that he does not seem to be getting any better.
Should you be concerned with this scenario?  What is concerning?  What might you say to the mother?

Baby Mitchell, 4 months old, is brought to the hospital by his mother.  He presents with difficulty gaining weight.  His mother states “he just gets so tired when he eats, and sometimes when he is nursing he has bluish color around his lips.”
What concerns you with the above scenario?  What might be your next course of action?
