|---|---|---|---|---|---|
| How does ADH (antidiuretic hormone) work? | show 🗑
|
||||
| How does aldosterone work? | show 🗑
|
||||
| show | Decreased vascular colloid pressure, increased capillary hydrostatic pressure, increased capillary permeability, lymph obstruction.
🗑
|
||||
| show | Colloid osmotic pressure is the pulling force of albumin (protein) in the intravascular space.
🗑
|
||||
| What would be the result of low colloid osmotic pressure? | show 🗑
|
||||
| show | A decrease in serum protein (albumin), as in malnutrition, burns or liver damage result in low colloid osmotic pressure.
🗑
|
||||
| What would happen to the blood volume if more water stayed in the interstitial space? | show 🗑
|
||||
| show | An increase in capillary hydrostatic pressure will cause fluid & solutes to be forced into interstitial space or prevent colloid osmotic pressure from pulling water in.
🗑
|
||||
| What would increased capillary permeability cause? | show 🗑
|
||||
| How does inflammation, burns or allergic reactions effect edema? | show 🗑
|
||||
| What is hypervolemia? | show 🗑
|
||||
| show | Weight gain, peripheral edema, distended neck & peripheral veins, bounding full pulse, polyuria, pulmonary edema, moist rales. Serum sodium levels may be normal or decreased due to dilution.
🗑

| What is hypovolemia? | show 🗑
|
||||
| What are causes of hypovolemia? | show 🗑
|
||||
| What is the treatment for hypovolemia? | show 🗑
|
||||
| What are clinical indications of fluid volume deficiency? | show 🗑
|
||||
| show | Third spacing is a shift of fluid from the vascular bed to the interstitial space. The vascular volume is reduced, but the person will have edematous tissue.

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
