10 Questions
In response to an increase in extracellular fluid (ECF) osmotic concentration, where does water move?
From ECF to ICF
What happens to fluid when extracellular fluid (ECF) osmotic concentration decreases?
Fluid becomes hypotonic to ICF
What is the main driving force for rapid water movements between the extracellular fluid (ECF) and intracellular fluid (ICF)?
Osmotic gradient
Why does severe water loss lead to dehydration if electrolytes are retained?
ECF osmotic concentration rises
What is the consequence of a body compartment becoming dehydrated?
Preference for isotonic conditions
What is the first-line treatment for dehydration according to the text?
0.9% NACL (saline solution)
What is the potential danger of giving a hypotonic solution to a severely dehydrated patient?
It may cause cells to swell and burst
What condition might be a concern when administering a hypotonic solution to patients with renal or cardiac disease?
Edema in the lower legs
What effect does giving a hypertonic solution have on cells?
Pulls water out of the cells causing them to shrink
What are common causes of overhydration as per the text?
Ingestion of large volume of fresh water and injection of hypertonic solution
This quiz covers rapid water movements between extracellular fluid (ECF) and intracellular fluid (ICF) in response to osmotic gradients. Learn about the shifts that occur when there are changes in osmotic concentration in different compartments.
