NSG 310 Fluid and Electrolytes Review
Questions and Correct Answers
What percentage of the human body is water? ✅60%

What is intracellular fluid? ✅Fluid inside of the cell

What is extracellular fluid? ✅Fluid outside of the cell

What percentage of body weight is due to intracellular fluid? ✅40%

What percentage of body weight is due to extracellular fluid? ✅20%

Where is most extracellular fluid found? ✅In intravascular spaces

What are intravascular spaces? ✅Spaces outside of the cell wall

What is interstitial fluid? ✅Filtrate of blood located between cells or between cells and
capillaries

True or false? If false, why?

Interstitial fluid has a similar protein content to that of blood. ✅False! Interstitial fluid
has no protein.

True or false? If false, why?

When fluid shifts, electrolytes shift. ✅True!

What is hydrostatic pressure? ✅The force of fluid pressure in the bloodstream

What is osmotic pressure? ✅The pressure by solutes in a solution

What is oncotic pressure? ✅The pressure created by albumin in blood

What is another term for oncotic pressure? ✅Colloid pressure

What is albumin? ✅A plasma protein that helps retain water

If you do not eat and your body lacks protein, fluid will shift externally via _____
pressure ✅Oncotic

, What kind of pressure causes blood pressure? ✅Hydrostatic pressure

What causes osmotic pressure? ✅Water at different concentrations due to the dilution
of water by dissolved molecules (solutes like salt and nutrients)

______ pressure pushes outward on the capillary whereas _____ pressure pulls inward
✅Hydrostatic; osmotic

What is tonicity? ✅The amounts of solutes in solution compared with the bloodstream

What is an isotonic solution? ✅A solution with the same tonicity as blood

How does an isotonic solution affect fluid shifting and cell size? ✅It doesn't; the tonicity
is the same so fluid is in equilibrium

What is the standard isotonic solution? ✅0.9% NaCl (normal saline)

What is a lactated ringer? ✅A solution with similar physiological constituents as those
found in blood

What is a hypotonic solution? ✅A solution that has fewer particles (and more water)
than blood

How do hypotonic solutions affect fluid shifting and cell size? ✅Fluid shifts from the
ECF into the ICF, causing cells to swell

What is the standard hypotonic solution? ✅0.45% NaCl (half normal saline)

What is a hypertonic solution? ✅A solution with more particles (and less water) than
blood

How do hypertonic solutions affect fluid shifting and cell size? ✅Fluid shifts from the
ICF into the ECF, causing cells to shrink

Which is more often used, a hypotonic or hypertonic solution? ✅Hypotonic

Question:

The client in the ER is being admitted following a motor vehicle accident with an acute
blood loss. What IV solution will the ER nurse hang initially as fluid replacement?
✅Lactated ringers or 0.9% NaCl (an isotonic solution)

Why are capillary beds so important? ✅Gas exchange occurs here
