Answer to Question 1

A
A postnatal change in the respiratory system is the stimulation of respiration by hypoxemia, hypercarbia, cold, tactile stimulation, and a possible decrease in the concentration of prostaglandin E2 . Inflation of the normal lung is complete within a few breaths, and most alveoli have expanded within the first hour of life. Surfactant in the lungs lowers surface tension and facilitates lung expansion. Pulmonary blood flow increases after birth.

Answer to Question 2

A, C, E
The signs of a UTI in an infant include fever or hypothermia, irritability, dysuria as evidenced by crying when voiding, change in urine odor or color, poor weight gain and feeding difficulties. Enuresis and voiding urgency would be assessed in an older child.
