Question 5
2 / 2 pts
Which are indications of dehydration?
Tachycardia and weight loss
Muscle weakness and decreased deep tendon reflexes
Polyuria and hyperventilation
Decreased hemoglobin and hematocrit
Question 6
2 / 2 pts
At the arterial end of capillaries, fluid moves from the intravascular space into the interstitial space because the
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.
interstitial oncotic pressure is higher than the interstitial 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.
cardiac cell hypopolarization.
cardiac cell hyperexcitability.
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.
pneumonia.
asthma.
emphysema.
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.
increased capillary permeability, which causes alveoli and respiratory bronchioles to fill with fluid.
Question 10
2 / 2 pts

20
40
30
10
Question 11
2 / 2 pts
The most successful treatment for chronic asthma begins with
drugs that reduce bronchospasm.
broad-spectrum antibiotics.
elimination of the causative agent.
drugs that decrease airway inflammation.
Question 12
2 / 2 pts
High altitudes may produce hypoxemia through
decreased inspired oxygen.
diffusion abnormalities.
hypoventilation.
shunting.
Question 13
2 / 2 pts
Which pleural abnormality involves a site of pleural rupture that act as a one-way valve, permitting air to enter on inspiration but preventing its escape by closing during expiration?
Open pneumothorax
Secondary pneumothorax
Tension pneumothorax
Spontaneous pneumothorax
