Answer to Question 1

ANS: A
Atelectasis develops when alveoli do not expand. Breathing exercises increase lung volume and open the airways. Deep breathing opens the pores of Kohn between the alveoli to allow sharing of oxygen between alveoli. This prevents atelectasis from developing.

Answer to Question 2

ANS: C
Atrial fibrillation results in pooling of blood in the atria, forming emboli that can be pumped out to the rest of the body. The most common manifestations are stroke, myocardial infarction, and pulmonary embolus. A sudden and drastic drop in oxygenation and blood pressure can indicate both pulmonary embolus and myocardial infarction.
