AHN 568 FLUIDS ELECTROLYTES
COMPLETE CERTIFICATION REVIEW
PAPER 2026 FULL QUESTIONS AND
EXPERTLY DEFINED ACCURATE
SOLUTIONS GRADED A+
⩥Electrolyes are usually measured in? Answer: Milliequivalents per liter
⩥What are the two main compartments of body fluids? Answer:
intracellular and extracellular
⩥How much of the body's fluids are in the intracellular fluid? Answer:
2/3
⩥What are the compartments in the extracellular fluid? Answer:
Interstitial fluid, Intravascular, Transcellular
⩥What are the four main types of fluid movement? Answer: Osmosis,
Diffusion, Filtration, Active Transport
⩥Osmosis is the movement of water from? Answer: A lower
concentration of solutes to a higher concentration of solutes
, ⩥Diffusion is? Answer: Movement of solutes from a higher
concentration to a lower concentration
⩥Active transport is? Answer: The movement of solutes from a less
concentrated area to a more concentrated area of solutes using ATP
across a cell membrane.
⩥What happens with a decreased volume of extracellular fluid? Answer:
Stimulation of osmoreceptors in hypothalamic thirst center, which leads
to the sensation of thirst
⩥What happens when there is increased osmolarity of extracellular
fluid? Answer: Decreased saliva secretion, which leads to dry mouth,
which leads to sensation of thirst
⩥ADH does what? Answer: increases DCT permeability, which brings
more water back into the blood
⩥What is the most abundant cation in the ECF? Answer: Sodium
⩥What is normal serum level for sodium? Answer: 135-145 mEq/L
⩥What is normal serum level for potassium? Answer: 3.5-5.3 mEq/L
