Questions: Which of the following conditions promotes edema?
(a)Consequences of dehydration. If more water than solutes is lost, cells shrink.
(b)Consequences of hypotonic hydration (water gain). If more water than solutes is gained, cells swell.

Solution
Solution Steps
Step 1: Define edema
Edema is swelling caused by excess fluid trapped in the body's tissues.
Step 2: Analyze the given conditions
The question asks which condition promotes edema. Edema occurs when fluid accumulates in the tissues.
(a) describes dehydration. Cells shrink because the ECF osmotic pressure rises, drawing water out of the cells.
(b) describes hypotonic hydration. Cells swell because the ECF osmotic pressure falls, leading to water movement into the cells.
Step 3: Determine which condition causes edema
Hypotonic hydration leads to swelling as more water enters the cells than solutes are gained, mimicking edema.
