What is normal albumin level? Correct Ans - 3.5-5.0

What is normal hemoglobin level? Correct Ans - 12-18 for male

What is osmolality? Correct Ans - concentration of particles in
a solution

What is osmotic pressure? Correct Ans - physical force that
prevents fluid from moving out and through a semi-permeable
membrane

What does a hypotonic IV solution exert? Correct Ans - less
pressure, allowing fluid to move into the cell (toward higher osmotic
pressure)

What does a hypertonic IV solution do? Correct Ans - draw
fluid toward it, away from the cells

What does isotonic IV solution do? Correct Ans - creates no net
fluid movement

Hypotonic solution can cause what? Correct Ans - cells to
swell, would want to verify order if pt has brian swelling

,Hypertonic solution can cause what? Correct Ans - cell
shrinkage or dehydration

When would you use hypertonic solutions? Correct Ans - when
addressing increased intracranial pressure or with severely low
sodium

What can be a risk of rapid correction of low sodium? Correct Ans
- brain damage through osmotic demyelination syndrome

How does osmotic demyelination syndrome present? Correct Ans
- -ataxia
-confusion
-slurred speech
-drooling
-tremor
-weakness

What are the most commonly used crystalloids? Correct Ans -
isotonic solutions

What is oncotic pressure? Correct Ans - exerted by colloids or
proteins

What are colloids? Correct Ans - -contain protein
-increase colloid oncotic pressure
-plasma "expanders"
-may affect clotting factor through dilution effect

What are crystalloids? Correct Ans - -contains sodium, no
protein
-most commonly used isotonic

,What is the risk of too much isotonic solution? Correct Ans -
hypervolemia (ECV excess)

How fast can you give hypertonic solutions? Correct Ans - no
faster than 100mL/hr

What is the only solution that can be used for fluid resuscitation?
Correct Ans - isotonic solutions
"run wide open"
