IV Fluids

Question 1

draws water in cells from ECF (drawn out of the vessels)
- i.e., Dextrose & 0.45% NaCl NS

Answer 1

hypotonic fluids

Question 2

`cells neither shrink or swell with fluid movement
- i.e., LR’s & 0.9% NaCl NS

Answer 2

isotonic fluids

Question 3

draws water out of the cells into more highly concentrated ECF (moves into the vessels)
- i.e., 3% NaCl NS

Answer 3

hypertonic fluids

Question 4

• isotonic solution that is not for routine maintenance: only a lot of Na+ & Cl-
• temporarily expands ECF with circulatory issues
• also treats hypovolemia, metabolic alkalosis, mild hyponatremia, hypercalcemia
• used with admin of blood transfusion

Answer 4

0.9% NaCl NS

Question 5

• isotonic solution containing many electrolytes similar to plasma
• treats hypovolemia, burns, fluid loss from GI issues
• contains glucose

Answer 5

LR’s

Question 6

• hypotonic solution that provides Na+, Cl-, and free water
• allows kidneys to select/retain needed
• aids kidneys in elimination of solutes
• treats hypernatremia

Answer 6

0.33 % NaCl NS (1/3 strength NS)

Question 7

• basic fluid for maintenance
• hypotonic solution that provides Na+, Cl-, and free water
• treats hypernatremia

Answer 7

0.45% NaCl NS (1/2 strength NS)

Question 8

• hypertonic solution that supplies fluid & calories
• replaces electrolytes: shifts fluid from IC into intravascular space (expands vascular volume)

Answer 8

5% Dextrose in LR’s

Question 9

• hypertonic solution that treats SIADH
• temporarily treats hypovolemia if plasma expander not available

Answer 9

5% Dextrose in 0.9% NaCl
