22
Q

what is the #1 cause of hyperkalemia

A

renal failure

23
Q

what foods have potassium

A

banana, apricots, cantalope, green leafy veggies

24
Q

what is the normal calcium lab values

A

8.6-10.2 mg/dl

25
Q

what are the 3 forms Ca is found in

A

bound, ionized, complexed

26
Q

where is calcium 99% stored

A

bones and teeth

27
Q

ionized calcium promotes transmission of _____ impulse and ______ contractions

A

nerve; muscle

28
Q

if Ca is low phosphorous is

A

high

29
Q

what are the 4 calcium regulators

A

parathyroid hormone (PTH)
calcitonin
phosphate
vitamin D

30
Q

why do you want the pt up and walking

A

so Ca will not leave the bone and go into the blood stream and cause high Ca levels

31
Q

what calcium regulator helps keep calcium in the bone

A

calcitonin

32
Q

reciprocal relationship with Ca

A

phosphate

33
Q

what helps with Ca absorption and how can you get it

A

Vitamin D; sunshine and from dairy products

34
Q

what is the normal lab value for magnesium

A

1.3-2.3 mEq/L

35
Q

Mg is important for

A

neuromuscular function

36
Q

what is the big thing and most cause of hypomagnesium

A

alcoholism because they tend to not take in enough food

37
Q

what is the normal Phosphorous lab value

A

2.5-4.5 mg/dl

38
Q

what is phosphorous essential for

A

function of muscle and RBCs, nervous system, cell membrane activity

39
Q

Hypokalemia causes “body is trying to DITCH potassium”

A

Drugs (laxatives, diuretics, corticosteroids)
Inadequate intake of K (NPO, anorexia, N)
