Answer to Question 1

ANS: B
The apex of the heart is formed by the tip of the left ventricle and lies just above the diaphragm at the level of the fifth intercostal space.

Answer to Question 2

ANS: T
The combination of a reduced FRC and high O2oxygen consumption in infants renders them more susceptible to profound hypoxemia in situations that further disturb ventilation, lung vol-ume, and/or ventilation/perfusion matching.
