MCQ (Single Correct) +4 −1
Edema may occur due to following except
  • Starling's Equation of Microvascular Fluid Movement:
$$J_v = K_f \left[ (P_c - P_i) - \sigma (\pi_c - \pi_i) \right]$$
  • Factors Promoting Edema:
  • Increased capillary hydrostatic pressure ($P_c$) (congestive heart failure, venous obstruction).
  • Increased capillary permeability ($K_f$) (inflammation, toxins).
  • Obstruction of lymphatic drainage (lymphedema).
  • Decreased plasma oncotic pressure ($\pi_c$) (hypoalbuminemia).
    • Effect of Increased Plasma Proteins:

  • An increased concentration of plasma proteins elevates intravascular oncotic pressure ($\pi_c$), which reabsorbs fluid from the interstitial space into the vascular bed, thereby preventing edema.
  • nalysis:
  • (Increased concentration of plasma proteins): Correct (does not cause edema).
Correct option: (3) Increased concentration of plasma proteins
