Week 6-Fluid And Electrolytes Flashcards
What is the primary body fluid
Water
Water content/ movement varies based on what
Adipose tissue, age, etc.
Does water contain solutes
Yes.
Electrolytes and non electrolytes.
Intracellular
Within cell
Extracellular
Out of celll
Interstitial
Intravascular
Transcellular
Movements of fluid and electrolytes
Osmosis
Diffusion
Filtration
Active transport
Primary way of taking in fluids
Drinking
IOM recommended fluid intake
2700 mL for women
3720 mL for men
What percent of fluid should come from food
20%
What regulates fluid intake
Thirst:
Change in plasma osmolarity
Hypothalamus
Fluid output per day
Urine-1500 mL
Fluid output other than urine
Perspiration-skin
Exhaling-lungs
loose stool-100 to 200 mL per day
Does body naturally produce electrolytes
Yes
Benefits of electrolytes
Life sustaining
What do IV bags contain
Water and electrolytes
What does edema mean about organs
Kidneys and heart is working too hard
Which groups dehydrate quickly
Children and the elderly
Must cells always be oxygenated
Yes
What does soda do to cells
Sugar content dries out cells
Ascites
Fluid that goes to stomach
Associated with sodium and serosis
3rd spacing
Extracellular fluid build up in a body space
Can be caused by blister
Edema
Hormones
ADH
Renin-angiotensin system
Aldosterone
Thyroid Hormone
Brain naturetic factor
Diauretic
Water pill.
Gets rid of extra water by urinating
Enhances kidney activity
Lasix
Nonpotassium sparing diauretic
Contraindication
Treatment should not be used bc it can be harmful
Renin angiotensin system
Manages blood pressure when it drops.
It activates angiotensin two and cause vasoconstriction, which increases blood pressure
Angiotensin 1 and 2
Angiotensin 2
Retains sodium and water
HCT2-K+
Potassium sparing diuretic
Affects aldosterone
What is liver filled with
Blood.
We don’t se it due to filtration
Ask professor
How do electrolytes impact heart
Keeps it pumping
Major electrolytes
Sodium
Potassium
Calcium
Magnesium
Phosphate/phospharus
Bicarbonate
Sodium
ECF
Regulates fluid volume
Kidney reabsorbs
Potassium
ICF
Muscle contraction/ heart contract.
Kidneys eliminate
Calcium
Bone health
Neuromuscular function
Cardiac function
Magnesium
ICF/bone
Many cell functionss
Phosphate
ICF
Bound with calcium in teeth and bones
Bicarbonate
ICF and ECF
Acid base balance
Regulated by kidneys
Serve as buffer
Aldosterone
Released if blood pressure or fluid volume too low
Makes kidneys hold onto water
Causes kidneys to hold onto sodium
Makes kidney gets rid of potassium
Brain natriuretic factor
Protein that regulates blood pressure. Allows normal circulation and preventing clots.
Causes if fluid and electrolyte imbalance
Vomitting
Diarrhea
Sweating
Fever
Drinking too much water
Burns
Isotonic IV
Increases blood volume
Isotonic solutions
Normal saline
Lactated ringers
Dextrose 5 percent in water(but works as hypotonic once administered)
Aldosterone
Holds onto sodium and water and excretes potassium
