What are minerals?
|
Inorganic chemical compounds in the human body that act as catalysts to start/stop/slow/speed chemical reactions in the body.
|
|
What do minerals do?
|
Build and repair body structures (bones/teeth, skin/mucous membranes, nerves, connective tissues, sensory organs).
|
|
What are the 7 Major Minerals?
|
Calcium and Phosphorus,
Sodium and Chloride, Potassium and Magnesium, Sulfur |
|
The function of Calcium.
|
Builds dense bones and teeth,
binds with phosphorus, requires vitamin D as a catalyst, requires weight-bearing exercise, immobility can reverse bone density. |
|
Which major mineral acts as a clotting factor?
|
Calcium
|
|
Which diseases may cause calcium loss?
|
Diseases of the parathyroid gland, becasue it is regulated by the parathyroid gland.
|
|
Which type of exercise is not weight-bearing?
|
Swimming. Examples of weight-bearing exercises include walking, running, weight-lifting.
|
|
Too much Phosphorus causes what problem?
|
Kidney Stones
|
|
Name 2 Food sources for Calcium
|
Milk
cheese green leafy vegetables |
|
What major mineral is the leading cause of fatal poisoning in children?
|
Iron (Fe)
|
|
What is the function of Phosphorus?
|
Builds bones and teeth (with Ca).
Regulates pH level of the blood (important for infection control.) |
|
Which two major minerals can be seen on a standard x-ray?
|
Ca and P
(used to diagnose fractures and tooth decay) |
|
Name 2 dietary sources of Phosphorus.
|
Animal meat (muscle)
Legumes (peas and beans) |
|
What is the function of sodium (Na)?
|
Regulates water (fluid) balance in body
- binds to Chloride (Cl) to form NaCl - regulates fluid absorption and excretion from the kidneys Works opposite Potassium (K) to create cardiac electrical energy Na - relaxes muscles |
|
What is the normal concentration of NaCl in the body?
|
0.9% (concentration of normal saline)
|
|
Function of Chloride.
|
Regulate water (fluid) balance
- binds with Na to form NaCl Regulates pH balance of the blood -important for infection control |
|
Name 2 dietary sources of NaCL.
|
Table salt (dry NaCl)
Chlorinated water |
|
Function of Potassium.
|
Works opposite Sodium (Na) to create cardiac electrical energy (heartbeat)
Conducts nerve impulses to create muscle contractions (opposite (Mg) Regulates Glycogenesis (Glucose to Glycogen) Regulates fluid balance and pH levels |
|
Symptoms of low Potassium
|
fatigue
|
|
Name 2 dietary sources of Potassium.
|
Almost all plant and animal foods
|
|
Function of Magnesium (Mg)
|
Conducts nerve impulses to create muslce relaxation (opposite K)
Acts as a laxative (Magnesium citrate, Milk of magnesia) Acts as an antacid Used to stop contractions during preterm labor |
|
What is the best dietary source of Magnesium?
|
Green leafy vegetables
|
|
Function of Sulfur
|
Forms the structure of healthy hair, skin
When skin or hair burns, it gives off the unmistakable odor of sulfur from burning protein. |
|
Dietary sources of sulfur.
|
Cheese and eggs
Poultry and fish (When these protein foods spoil, they smell of sulfur) |
|
What are the 6 trace minerals?
|
Iron
Iodine Flouride Zinc Copper Selenium others: Chromium, Manganese, Cobalt, Molybdenum |
|
Function of Iron
|
Carries Oxygen to cells by forming hemoglobin compound in blood
|
|
Tests for oxygen capacity and RBC concentration
|
Hemoglobin level and serum Hematocrit
(H&H stat, Crit, Crit stat) |
|
Symptoms of iron deficiency anemia.
|
fatigue, paleness of skin and mucous membranes (pallor)
|
|
Test for iron storage
|
Serum Ferritin level
|
|
What is the most common nutritional deficiency in the US?
|
iron deficiency anemia
(especially for menstruating women) |
|
Dietary sources of Iron
|
Red meat
Organs (liver, kidneys) Eggs |
|
Function of Iodine (I)
|
Builds healthy muslce tissue, skin/mucous membrane cells, bone tissues
Acts as an antiseptic |
|
Where is Iodine Stored in the body?
|
Thyroid gland
Iodine deficiency may lead to an enlarged Thyroid gland (goiter) Diseases of this gland may cause iodine imbalances |
|
Dietary sources of Iodine.
|
iodized salt
shellfish/seaweed (the ocean is rich in iodine) |
|
Function of fluoride
|
Creates and maintains healthy teeth, reduces the occurence of dental decay
|
|
Sources of Fluoride
|
Sometimes in public water
Oral fluride supplements Toothpaste |
|
Examples of other trace minerals
|
Zinc
Copper Selenium |
|
Function of Zinc
|
Antioxidant that has skin healing properties (sunscreens and diaper creams)
|
|
What is hypercalcemia?
|
Serum calcium level that is too high, 11 milligrams per 100 milliliters for adults
Milk-alkalai syndrome Hyperthyroidism Too many antacids Vitamin D poisoning (most frequent in infants) Symptoms - calcium deposits in the soft tissues of the body |
|
Hypocalcemia
|
Serum calcium level that is too low
|
|
What is Ferritin?
|
Stored form of Iron in RBCs
|
|
Hypokalemia
Hyperkalemia |
Potassium too low/high
|
|
A client is recovering from a small-bowel resection. The nurse anticipates that the resection will proerly be healed when:
a) the client passes gas b) his abdomen becomes distended with air c) a normal, soft formed stool is passed d) his appetite returns and he tolerates soild food |
Answer is a
the lumen of the small bowel would be intact and the circular incision site healed when gas from the intestinal bacteria travel through to the rectum. If his abdomen becomes distended with air from the bowel, the incision site may not be healing but leaking air instead. The client will not pass a normal stool for several days after flatus is expelled and he will be kept on NPO status until passing gas. |
|
Hypernatremia
Hyponatremia |
Sodium too high/too low
|
|
If a client is ordered "Clear Liquid Diet" on the second day after heart surgery, which of the following drinks should the nurse recommend for breakfast?
