Week 6 Fluid/Electrolyte/Acid/Base

Question 1

Where is most of the body fluid found (compartment)?

Answer 1

Intracellular (2/3)

Question 2

What primary component is responsible for osmotic pressure?

Answer 2

Sodium

Question 3

Oncotic pressure is created by what component?

Answer 3

albumin

Question 3

Hydrostatic pressure opposes what other pressure?

Answer 3

Osmotic pressure. It is created by water pushing against the cell membrane.

Question 4

How do hypertonic solutions affect the fluid shifts?

Answer 4

Causes fluid to shift from the intracellular space to the intravascular space d/t the higher concentration of solutes in the fluids drawing out the fluids in the cells.

Question 4

How do hypotonic solutions affect the fluid shifts?

Answer 4

Cause fluid to shift from intravascular to intracellular d/t the low concentration of solutes drawing water into the cells.

Question 4

Does an isotonic solution cause fluid shifting?

Answer 4

No. It is the same concentration as our cells.

Question 5

What type of solution causes fluid to shift from intravascular to intracellular?

Answer 5

Hypotonic

Question 6

What hormone regulates water excretion?

Answer 6

ADH (antidiuretic hormone)

Question 7

What hormone conserves water by increasing reabsorption of water and sodium in the renal tubules?

Answer 7

Aldosterone

Question 8

What organ maintains most of the electrolyte and fluid balance?

Answer 8

Kidneys
