Composition Of Parenteral Fluids

Question 1

What is the difference between colloids and crystalloid s

Answer 1

Colloids
*molecular weight >8000
*high oncotic pressure
Crystalloids
*molecular weight of <8000
*low oncotic pressure

Question 2

What is isotonic fluid

Answer 2

Cell has the same concentration on the inside and outside

Question 3

What are different types of isotonic fluid

Answer 3

1. 0.9% NS
2. 5% dextrose in water (D5W)
3. 5% dextrose in 0.225% saline (D5 1/4NS)
4. LR

Question 4

What is isotonic fluid used for

Answer 4

1. To increase the Extracellular fluid volume due to blood loss, surgery, dehydration

Question 5

What is hypotonic fluid

Answer 5

Less Extracellular solute leads to shifting water into the cells, the cells will swell

Question 6

What are the different types of hypotonic fluids

Answer 6

1. 45% NS (1/2 NS)
2. 0.225% NS (1/4 NS)
3. 0.33% NS (1/3 NS)

Question 7

When is hypotonic fluid used?

Answer 7

1. When the cell is dehydrated and fluids need to be put back intracellular

Question 8

What is hypertonic fluid

Answer 8

The cell has an excessive amount of Extracellular solute, water is rushing out of the cell to the Extracellular area and shrinks
*hyper people are skinny

Question 9

What are the different types of hypertonic fluids

Answer 9

1. 3% saline
2. 5% saline
3. 10% dextrose in water (D10W)
4. 5% dextrose in 0.9% saline (D5NS), 5% dextrose in 0.45% saline (D5 1/2NS), 5% dextrose in LR
