Answer to Question 1

A
Peripheral vasodilation results in decreased venous return. This decreases intravascular volume and the development of relative hypovolemia. Decreased venous return results in decreased stroke volume and a fall in cardiac output.

Answer to Question 2

D
A contusion manifests initially as a hemorrhage followed by alveolar and interstitial edema. The edema can remain rather localized in the contused area or can spread to other lung areas. Inflammation affects alveolar-capillary units. As more units are affected by inflammation, further pathophysiologic events can occur, including decreased compliance, increased pulmonary vascular resistance, and decreased pulmonary blood flow. These processes result in a ventilationperfusio n imbalance that results in progressive hypoxemia and poor ventilation over a 24- to 48-hour period.

Fatal fungal infections may be able to resist newer antifungal drugs. Globally, fungal infections are often fatal due to the lack of access to multiple antifungals, which may be required to be utilized in combination. Single antifungals may not be enough to stop a fungal infection from causing the death of a patient.
