Electrolytes Flashcards
Function:
Controls fluid osmolality and volume of blood
Stimulates conduction of electrical impulses along nerves
Works with calcium to regulate muscle contraction
Sodium Na+
normal blood range:
135-145 mEq/L
Sodium
Sources for intake:
Salt: Most individuals obtain 90%–94% from packaged, processed foods, including bacon, ham, canned vegetables, soy sauce, steak sauces, other sauces, salad dressings, processed cheeses, sandwich meats, salty snacks such as chips, jerky, pretzels, canned soups, broths
Adding table salt to prepared foods
Sodium
Normal range: 97-107 mEq/L
Chloride CL-
Functions:
Assists sodium in regulating fluid osmolality and volume
Important for acid-base balance Production of gastric HCl
Chloride
Source for intake:
High-sodium-content foods listed above
Lettuce, tomatoes, celery, olives, seaweed
Chloride
Normal blood range:
3.5-5.3
Potassium
Function:
98% in ICF helps regulate fluid balance 2% in ECF is important for neuromuscular functions, especially for the heart’s contractility and rhythm
Potassium
Source for intake:
Dried fruits, tomatoes, potatoes, spinach and other leafy greens, oranges, bananas, cantaloupe, red meat, chicken, fish, nuts, soy products
Potassium
Normal blood range:
1.6-2.2 mg/dL
Magnesium (Mg2+)
Functions:
Assists neuromuscular function; dilation of arteries and arterioles; enzyme function; carbohydrate and protein metabolism
Magnesium
Source for intake:
Leafy green vegetables, whole grains, beans, fish (halibut), almonds, soybeans
Magnesium
Normal range:
8.2-10.2
Calcium
Functions:
Strengthen skeletal bones and teeth Ionized Ca2+: stimulates conduction of electrical impulses via nerves, which controls muscle contraction and relaxation, includes heart muscle Initiates enzyme action Cellular membrane permeability
Calcium
Source of intake:
Dairy products, green vegetables, shellfish, salmon, dried beans
Calcium
Normal range:
2.5-4.5 mg-Dl
Phosphorus
Function:
Vital for all tissues; muscle and red blood cell functions; metabolism of fat, protein, carbohydrates; manufacturing ATP energy source
Phosphorus
Source of intake:
Meats, fish, egg yolks, dairy products, nuts, beans, legumes, whole grains, soft drinks
Phosphorus
what are serum pH?
7.35-7.45
What are normal CO2?
35-45
What are normal HCO3?
22-26
If Ph and CO2 arrows go different direction its?
Respiratory
If ph and CO2 arrows go same direction its?
metabolic
Describe intracellular fluids and where are they found?
Intracellular fuilds are found in 2/3 of body fluids with the cell.
