Q

Untreated changes in potassium levels can lead to what?

A

Serious neuromuscular and cardiac problems

26
Q

What is the normal potassium levels

Intro or extra cellular?

A

3.5 to 5

Intracellular

27
Q

Most potassium ingested is excreted by what organ?

A

Kidneys

28
Q

What three things influence potassium balance?

A

Sodium/potassium pump

Renal regulation

Ph level

29
Q

This uses ATP (energy) To pump potassium into cells

Pump sodium out of cells

And creates a balance

A

Sodium/potassium pump

30
Q

This causes sodium reabsorption and potassium excretion for renal regulation

A

Aldosterone

31
Q

What would potassium acidosis mean?

A

Hyperkalemia, potassium moves out of cells

32
Q

What would potassium alkalosis mean?

A

Hypokalemia, potassium moves into cells

33
Q

Potassium imbalances are caused by what

A

Dialysis, dehydration, too much fluid,NG suction

34
Q

What happens to the body with hyperkalemia or high potassium?

A

Numbness in the fingers, hypotension,EKG T waves, diarrhea

35
Q

What happens to the body with hypo kalemia or low potassium?

A

Toxicity digitalis

Orthostatic hypertension

EKG

Weak pulse

Constipation

36
Q

What should you never give to somebody with potassium imbalance?

A

IV push

37
Q

What is the medication to help get rid of extra potassium by stool?

A

Kayexalate

38
Q

What can you do for someone with potassium imbalances?

A

Loop diuretics (lasix)

Dietary restrictions

39
Q

This helps produce energy, protein synthesis and carbohydrate metabolism, helps heart system function vasodilation, regulates or slows muscle contractions switches Charlie horses

A

Magnesium

40
Q

Normal magnesium level

Intro or extracellular?

A

1.5-2.5

Intracellular

41
Q

What are signs of hypermagnesmia ?

A

Renal failure is the most common cause

Weakness, nausea vomiting, hypoactive DTRs, neuromuscular activity

42
Q

Signs of hypomagnesemia?

A

Hypertension *

Tachycardia, anorexia, muscle weakness,Altered LOC

43
Q

normal calcium level?

A

9-10

44
Q

This electrolyte Works with phosphorus to form bones and teeth

It affects heart muscle contraction, blood clotting, needs vitamin D to properly absorb into body, parathyroid( pulls )hormone drugs calcium from bones, Calcitonin is released by the thyroid to (keep) calcium

A

Calcium

45
Q

Signs of Low calcium?

A

Fractures in bones, diarrhea, EKG changes, slow response to digoxin, Muscle spasm’s mouth and parentheses

46
Q

To do for someone with low calcium?

A

Give with vit d

Supplements

47
Q

Symptoms of hypercalcemia

A

Bradycardia or cardiac arrest

Fatigue, muscle weakness, anorexia, decreased bowel sounds, constipation, polyuria or increase of urine, kidney stones, renal failure

48
Q

What Do for someone who has too much calcium

A

Hydrate the patient, loop diuretics, steroids corticosteroids, three underlying cause

49
Q

What to do for someone with hyper magnesium

A

Increase fluids, blue diuretic if no one responds to fluids,

50
Q

What is the major role that water and electrolytes play in the body ?

A

Regulation of homeostasis by regulating substances that affect pH

51
Q

Which compartment of fluids is easier to measure?

A

ExtraCellular fluid

52
Q

What are two important hormones that regulate water balance?

A

Aldosterone and anti-diuretic hormone

53
Q

What hormones are calcium influenced by?

A

Calcitonin and parathyroid hormone

54
Q

Who is at the greatest risk for electrolyte in balance?

A

Infants And elderly

55
Q

Go different way that fluid and balance can happen?

A

Loss of fluids from vomiting, diarrhea, severe sweating, high fever, loss of blood

56
Q

What are different ways of electrolyte in balance this can happen?

A

Imbalance of fluid volume,

failure of organs that help regulate electrolytes such as kidney failure

57
Q

What is used to form carbonic acid which breaks down hydrogen ions and bicarb?

A

Carbon dioxide and water

58
Q

A drug that contains large amounts of salicylic acid

A

Aspirin

59
Q

What regulates CO2 balance?

A

And respiratory system and lungs

60
Q

What forms carbonic acid?Which leads to acid building up

A

CO2 and H2O

61
Q

Any problem that leads to hyperventilation can lead to what?

This is caused by alterations of the renal or G.I. system or inability of the buffering systems

This can be related to access loss of acids, from G.I. losses or alternations in renal function

Infection, chronic lung condition, excessive medication that suppresses the respiratory drive or acute injury that impairs respiration

A

Respiratory alkalosis

Metabolic acidosis

Metabolic Alkalosis

Respiratory acidosis
