capillary oncotic pressure is lower than the interstitial hydrostatic pressure.

capillary hydrostatic pressure is higher than the capillary oncotic pressure.

interstitial hydrostatic pressure is higher than the capillary hydrostatic pressure.

Question 7

2 / 2 pts

In hyperkalemia, cardiac rhythm changes are a direct result of

cardiac cell repolarization.

depression of the sinoatrial (SA) node.

Question 8

2 / 2 pts

Clinical manifestations that include unexplained weight loss, dyspnea on exertion, use of accessory muscles, and tachypnea with prolonged expiration are indicative of

chronic bronchitis.




Question 9

2 / 2 pts

In ARDS, alveoli and respiratory bronchioles fill with fluid as a result of the

compression on the pores of Kohn, thus preventing collateral ventilation.

inactivation of surfactant and the impairment of type II alveolar cells.

increased capillary hydrostatic pressure that forces fluid into the alveoli and respiratory bronchioles.

2 / 2 pts

High altitudes may produce hypoxemia through

decreased inspired oxygen.

Question 13

2 / 2 pts

apoptotic infected macrophages that activate cytotoxic T cells.

phagocytosis by neutrophils and eosinophils.

formation of immunoglobulin G to initiate the complement cascade.

Question 16

2 / 2 pts

disruption of alveolocapillary membrane.

pulmonary fibrosis.

pulmonary hypertension.
