LVN 101 (Tuesday) FLUID and ELECTROLYTES

Question 1

There are two major fluid compartments. What are they?

Answer 1

INTRAcellular (inside cell) and EXTRAcellular (outside cell)

Question 2

Which of the two major fluid compartments is the largest?

Answer 2

Intracellular

Question 3

Which of the two major fluid compartment has two subdivision?

Answer 3

Extracellular

Question 4

Extracellular fluid compartment has two subdivision, what are these?

Answer 4

INTERstitial (between cells) and INTRAvascular (inside vessel)

Question 5

This extracellular fluid compartment subdivision accounts for appx 27% of the fluid in the body. Examples of this are lymph, cerebrospinal fluid, and gastrointestinal secretions.

Answer 5

Interstitial

Question 6

This extracellular fluid compartment subdivision makes up 7% of fluid volume and is called “plasma” within the vessel.

Answer 6

Intravascular

Question 7

Review: There are two major compartments: Intracellular and extracellular. Intracellular is larger that extracellular. Extracellular has two subdivision: Interstitial and intravascular. Interstitial accounts for 27% of the fluid in the body such as lymph, cerebrospinal fluid, and gastrointestinal secretion. Intravascular accounts for 7% and is the “plasma” within the vessel.

Answer 7

Major Fluid Compartment
Intracellular vs Extracellular

Extracellular subdivision:
Intravascular vs interstitial

Question 8

Several methods are used by the body to move fluids, electrolytes and other solutes, or dissolve substances into and out of cells. Name two major transports.

Answer 8

Passive transport (requires no cellular energy) and Active transport (requires cellular energy)

Question 9

Critically Think About This. What is the difference between diffusion and osmosis?

Answer 9

Diffusion: SOLUTES move from high to low
Osmosis: WATER moves from high to low

Question 10

This type of passive transport is found in your kidney…

Answer 10

Filtration (passage of water and dissolved substances from higher pressure to lower pressure

Question 11

Who is the responsible for the amount of force of the hydrostatic pressure that causes water and electrolytes to move from the capillaries to the interstitial fluid?

Answer 11

The pumping action of the heart

Question 12

Cations have positive charge. “I POSITIVE-ly lost my CAT.”

Answer 12

Anions have negative charge.

Question 13

REVIEW: Passive transport: Diffusion, Osmosis Filtration

Question 18

This regulates water balance, controls extracellular fluid volume, increases cell membrane permeability, stimulates conduction of nerve impulses and helps maintain neuromuscular irritability, controls contractility of muscles.

Na+
K+

Answer 18

Na+

Question 19

This regulates water and electrolyte WITHIN the cell.

Na+
K+
Ca++

Answer 19

K+

Question 20

Vitamin D, calcitonin and parathyroid hormone are necessary for absorption and utilization of this…

Na+
K+
Ca++

Answer 20

Ca++

Question 21

REVIEW: Na+ most common, regulates a whole buncha things

K+ most common INSIDE cell, regulates water and electrolyte inside cell

Answer 21

Ca++ 99% in bones and teeth, helps keep blood level constant. needs vit D, calcitonin and parathyroid hormone to be absorbed and utilized
