What portion of the developing brain eventually becomes the medulla?

A respiratory therapist is evaluating a chest radiograph of a patient taken 2 days after being admitted for significant respiratory distress and right middle lobe pneumonia with not causative organism identified. The patient has not improved. What imaging study should the therapist suggest to evaluate the patient’s condition?

A pediatric patient with pneumonia has mediastinal contours. What is a possible cause?

 CPAP levels greater than 8 cm H2O are commonly associated with which of the following conditions

A 1-month-old prematurely born baby boy with a diagnosis of respiratory syncytial virus (RSV) pneumonia is receiving PC-CMV. The patient’s initial measured VT was about 5 mL/kg with a respiratory rate of 40 to 60 breaths/min, the SpO2 was 95% on an FIO2 of 0.3, and  was 0.28 L. Over several hours, VT diminishes to about 2 to 3 mL/kg and the respiratory rate increases to over 100 breaths/min. The SpO2 decreases to about 92%, but the  remains unchanged. What change in ventilator settings is necessary for this patient?

The most common interface used to deliver CPAP to spontaneously breathing infants is:

A therapist is viewing a chest X-ray of a newborn that is experiencing cardiac arrhythmias. She notices in the chart the newborn recently had a UVC placed for short term medication administration. Which of the following could be an explanation of the arrhythmias?

Physiologic effects of CPAP include the following except:

You are called to assist with a full-term neonate who was transferred to your facility for further evaluation. The patient is the son of a diabetic mother who tested positive for group B streptococcus infection. He is 4 kg, has received one dose of surfactant, and has extremely low lung volumes on AP chest radiograph. The transport team has the infant on continuous mandatory ventilation (CMV), pressure control rate of 60, peak inspiratory pressure (PIP) of 32, positive end-expiratory pressure (PEEP) of 8, and fraction of inspired oxygen (FiO 2) of 1.0. These ventilator settings are producing a peripheral capillary oxygen saturation (SPO 2) of 85%, with admission blood gas values of 7.15/65/66/23. What mode of ventilation would you suggest for this patient and why?

As the therapist auscultates over an infant’s larynx, he hears a very low-pitched sound. Based on this finding, what impression is he or she likely to have regarding the nature of the upper airway obstruction?
