Fluid is aspirated from the grossly distended abdomen of a 47-year-old chronic alcoholic man. The fluid is straw colored and clear and is found to have a protein content (largely albumin) of 2.5g/dL. Which of the following is a major contributor to the fluid accumulation in this patient?
A: Blockage of lymphatics
B: Decreased oncotic pressure
C: Decreased sodium retention
D: Increased capillary permeability
E: Inflammatory exudation

举一反三
- Which one is the main mechanism of inflammatory edema? ( ) A: Decreased plasma colloid osmotic pressure B: Increased capillary permeability C: Lymphatic obstruction D: Increased ANP E: Decreased GFR
- Which is correct to explain the fluid exudation? A: The intravascular fluid accumulation is termed as edema B: Exudate has two patterns, edema and transudate C: Exudate contains more blood cells, and high protein content D: Exudate is formed in the microcirculation with normal vascular permeability
- What does edema mean? A: swelling induced by increased body fluid B: too much intracellular fluid C: too much extracellular fluid D: the accumulation of excess fluid within the interstitial space
- Which of the following determines the distribution of the extracellular fluid between the plasma and interstitial spaces? A: Sodium and protein concentrations in the extracellular fluid B: Balance between hydrostatic and colloid osmotic forces C: Osmotic pressure within cells surrounding an interstitial space D: Water concentration within the interstitial spaces
- The mechanism of lower extremity edema in patients with right heart failure does not include: A: Increased capillary permeability B: Retention of sodium and water C: Systemic venous congestion D: Hypoproteinemia E: Increased capillary hydrostatic pressure
