IV Fluids - Week 2

Question 1

Describe osmosis

Answer 1

Movement of water through semipermeable membrane from an area of low solute concentration to an area of high solute concentration until equilibrium is reached

Question 2

What is molarity

Answer 2

Number of moles in 1L of fluid

Question 3

What is osmolarity (osmotic concentration)

Answer 3

Number of particles present after being dissolved in 1L of fluid

Question 4

What is tonicity

Answer 4

measure of osmotic pressure gradient between two solutions

Question 5

If a compound dissociates in water how does it effect molarity vs osmolarity?

Answer 5

Osmolarity increases due to higher number of solutes

Question 6

what is a hypertonic solution

Answer 6

Solution with a relative higher osmolarity/solute compared to normal body cells and blood

Question 7

what is a hypotonic solution

Answer 7

Solution with a relative lower osmolarity/solute compared to normal body cells and blood

Question 8

what is an isotonic solution

Answer 8

Solution with the same osmolarity/solute compared to normal body cells and blood

Question 9

Drip rate equation

Answer 9

Volume to be infused (ml) x drip rate (20gtt) / time for infusion (minutes)
