ISOTONIC HYPERTONIC HYPOTONIC (EASY!)

Are you confused about what isotonic, hypertonic and hypotonic actually mean?

IV solutions, fluid tonicity and fluids and electrolytes are HUGE topics in nursing school.

In this video, I'll walk you through the EASIEST way to remember isotonic, hypotonic and hypertonic for nursing school.

Here's a breakdown of what we'll talk about:

ISOTONIC:

Think: "I SO want to stay here!"

With isotonic solutions, there is a proper balance of water and solutes. It's the same osmotic pressure inside and outside of the cell.
Isotonic solutions don't cause fluid to shift inside or outside of the cell.

HYPERTONIC:

Think: HYPER cells!
Hypertonic solutions have more solutes than water (compared to isotonic solutions)
Hypertonic solutions will cause fluid to move OUT of the cell
The cell will shrivel


HYPOTONIC:

Think: HIPPOS!
Hypotonic solutions have more water than solutes (compared to isotonic solutions)
Hypotonic solutions cause fluid to move INTO cells
The cell will expand and burst
