Awoman reports to the emergency room in january with her cyanotic (blue-colored) 10-month-old child. the mother reports that the infant has had a runny nose, fever, and slight cough for a day and has had increasing trouble breathing. the child does not have a history of bronchial disease and was not premature. the mother also states that the infant's five-year-old brother is recovering from symptoms that resemble a cold.

Because of symptoms and age, we would consider some diagnosis of bronchitis due to RSV infection, pneumonia because of Haemophilus influenza infections, and pertussis infection including apnea. Here I can say the answer is pneumonia due to infection of Haemophilus influenza.
The kind of treatment we can give depending on my diagnosis are; high dosage of oral erythromycin to clear the infection bacteria, supportive therapies in hospital in order to maintain blood oxygen levels and in open airways, low dosage of erythromycin which is given intravenously to clear the infection of bacteria which I can say it is the best treatment.
Some of the treatment for the infant to diminish such infection chances are MMR vaccines, toxin antiserum DTaP vaccine, influenza shot which I can recommend for the infant.
The best reason I can say about these conditions and symptoms are associated with pneumonia whereby we can say the low dose of erythromycin which is given intravenously is effective. The best prophylactic treatment is influenza shots.
