A male infant weighing 3200 grams is born to a G1P1 female at 39 weeks' gestational age via planned C-section. Maternal PMH is unremarkable, and GBS status is negative. Apgars are 7 and 8 at 1 and 5 minutes of life, respectively. The delivery was uncomplicated, and the infant initially appeared in good condition. However, one hour following delivery the infant develops increasing respiratory distress. Respiratory rate is assessed as 90 breaths/min. All other vital signs are within normal limits. On exam, the infant is acyanotic with rapid respirations and robust capillary refill. Chest x-ray shows bilateral lung fields with the appearance of "a radio-opaque line of fluid in the horizontal fissure of the right lung." No air bronchograms are noted. What is the most likely etiology of the infant's respiratory distress?

A 12-year-old female presents to her pediatrician complaining of a headache of gradual onset x 3 hours, non-provoked and described as a "big rubber band around my whole head" and a 5 out of 10 on the pain scale.

Physical exam is remarkable for an irritable but consolable infant with tachycardia and normal blood pressure. He is crying with minimal tears and his mucous membranes are dry. His abdominal exam is benign. There is no tenting, and capillary refill is 2 seconds. He is diagnosed with gastroenteritis and started on rehydration therapy. Which of the following statements is true?

The patient is moderately dehydrated and should be managed with 50-100ml/kg of oral rehydrating solution over 2-4 hours.

Given that the medical assistant was unable to check the vision and hearing for the patient, what would be your next steps in this assessment?

While vision screening is recommended to start at 3 years, many patients cannot yet do chart based screening. All children should be given two tries at separate visits before referring them to a specialist for an exam. So in this case, the vision testing can be repeated at the next visit as long as the parents don't have any specific vision concerns today.
