Ch 27: Electrolyte, Acid/base Balance Flashcards
(46 cards)
The higher the solutes, the higher the osmolality?
True
There are more ICF in the body than ECF
True
Ascending from bottom to top of loop of henle will..
The osmolality will decrease
What does ECF include?
Plasma and interstitial fluid
Cation potassium
K+ Most abundant for ICF
Largest amount for sodium for ECF
Anion
Larger amount of sodium in ECF
Larger amount of proteins in ICF
more chloride in ECF
Fluid movement
In and out of blood are hydrostatic pressure and osmotic pressure
Osmosis
Process of passive movement
Is drinking fluid the fastest method without an IV line 
True
What is the quickest way of eliminating fluids?
Urinating
Hypothalamic osmoreceptor’s
Control thirst
Sodium levels and drinking water
⬇️ Na+: ⬇️ drinking water
⬆️ Na+: ⬆️ drinking water
Increase volume of ADH
Decreases the volume of ADH
Increasing ADH
Increases volume of ADH
What is the greatest influence of osmolality?
Sodium
What does aldosterone do?
Intake sodium first
What does ADH absorb?
Absorbs water only
What happens if you increase ADH
Hypertension:
⬆️ solutes
⬇️ H2O
What happens when you reduce ADH
Hypotension:
⬇️ solutes
⬆️ H2O
Ranges of regulation of sodium
135-145 mEq/L NORMAL
hyperatremia:> 145
Hypoatremia: <135
Homeostasis of hyperkalemia
⬆️ aldosterone ⬆️ K+ and H+
Then decrease in K+
- opposite happens with hypokalemia
Sign v. Symptom
Sign: doctor sees
Symptom: patient experiences
Calcium levels
Normal: 8.2-10.2
<8.2 hypocalcemia
>10.2 hypercalcemia
Magnesium levels
Normal: 1.7-2.2
<1.7: hypomagnesemia
>2.2: hyperm
