NUR 252 – Fluid and Electrolyte Study
Questions and Correct Answers
Fluid and Electrolyte balance ✅The process of regulating the extracellular fluid
volume, body fluid osmolality, and plasma concentration of electrolytes
What is fluid? ✅Fluid is water plus the substances dissolved and suspended in it
What are the characteristics of Fluid & Electrolyte balance? ✅1. Volume (amount)
2. Concentration (osmolarity)
What is sodium responsible for? ✅ECF osmotic balance
What is potassium responsible for? ✅ICF osmotic balance
Edema ✅excessive accumulation of fluid within the interstitial spaces
Why does hydrostatic pressure increase? ✅As a result of venous obstruction or salt
and water retention
What does venous obstruction cause? ✅Hydrostatic pressure to increase being the
obstruction, pushing fluid from the capillaries into the interstitial spaces
What is associated with excessive salt and water retention and what does it case?
✅Congestive heart failure, renal failure, and cirrhosis of the liver are associated with
excessive salt and water retention.
This causes plasma volume overload, increased capillary hydrostatic pressure and
edema
What are causes of edema? ✅Increased capillary hydrostatic pressure
Increased capillary permeability
Decreased colloid osmotic pressure
Obstruction in lymphatic system
Excess body water and sodium
How does lost or diminished plasma albumin production (ie: liver disease) lead to
edema? ✅Lost or diminished plasma albumin (ex: liver disease) contributes to
