A 70-year-old male with chronic renal failure presents with edema. Which of the following is the most likely cause of this condition?
A) Increased capillary oncotic pressure
B) Increased interstitial oncotic pressure
C) Increased capillary hydrostatic pressure
D) Increased interstitial hydrostatic pressure

Question

Quizplus · Accepted Answer

Chronic renal failure can cause decreased glomerular filtration rate, leading to a decrease in urine output and fluid accumulation in the body, which can increase capillary hydrostatic pressure and cause edema. Increased capillary oncotic pressure is seen in conditions like hypoalbuminemia, while increased interstitial oncotic pressure is seen in conditions like lymphatic obstruction. Increased interstitial hydrostatic pressure can be seen in conditions like heart failure. However, none of these are the most likely cause in a patient with chronic renal failure presenting with edema.
