Question

the nurse assesses edema in a newly admitted client. further evaluation is based on the fact that the nurse knows edema is caused by (select all that apply.) increased capillary blood pressure increased capillary membrane permeability colloid osmotic pressure blockage of lymphatic drainage low plasma protein levels

Explanation:

Increased capillary blood pressure forces fluid out of capillaries into interstitial space causing edema. Increased capillary membrane permeability allows more fluid to leave capillaries. Blockage of lymphatic drainage prevents fluid return to circulation. Low plasma protein levels reduce colloid - osmotic pressure, leading to fluid shifting into interstitial space. Colloid osmotic pressure itself doesn't cause edema when normal; it helps retain fluid in capillaries.

Answer:

A. increased capillary blood pressure
B. increased capillary membrane permeability
D. blockage of lymphatic drainage
E. low plasma protein levels
