What is vasogenic cerebral edema? - ANSWER✔✔-Vasogenic cerebral edema is an

increase in extracellular fluid caused by a breakdown of the blood-brain barrier with the

becomes more generalized. Common causes are trauma (including surgical trauma),

tumors, hemorrhage, and abscesses


What ventilator parameter indicates fluid volume excess? - ANSWER✔✔-An A:a

gradient greater than 10 mm Hg is a reflection of a diffusion defect. Note that the

process of diffusion is between A (alveolus) and (a) arterial blood. An increase in

intraalveolar fluid dilutes and inactivates surfactant, causing alveolar collapse

(decreasing vital capacity) and decreases lung compliance. Peak inspiratory pressure

increases reflect a decrease in lung compliance

What are omnious signs in a patient with status asthmaticus? - ANSWER✔✔-A

normalization or increase in the PaCO2. This patient is still tachypneic, and if

ventilation is normal, PaCO2 should be decreased. The other ominous sign in this

patient would be absence of wheezing or rhonchi, because they would indicate that

ventilation is insufficient to cause these noises.


What problems arise from losses from the GI tract? - ANSWER✔✔-Any loss results in

hypokalemia. Vomiting results in loss of acidic contents, whereas losses below the

pylorus result is alkalitic losses leading to metabolic acidosis. Fluid is sequestered in the

intestine leading to hypovolemia, which could cause hypovolemic shock.


Actual problems are worse than potential problems!! - ANSWER✔✔-


How can you differentiate the cause of jaundice? - ANSWER✔✔-An increase in direct

(valsartan [Diovan]). Of the beta-blockers, labetalol works best. Of the calcium channel

blockers, diltiazem works best


What lab values define acute respiratory failure? - ANSWER✔✔-50-50!
