potassium

Question 1

k FUNTIONS

Answer 1

NORMAL CARDIAC RTHYMS
sketetal and smooth muscle contraction
THINK MUSCLES

Question 2

how do changes in K impact pH

Answer 2

during acidosis there is too many H atoms in the ICF so K moves out to even the postive charge

Question 3

what impact does k HAVE ON EKG

Answer 3

HORRIBLE IMPACT IF LEVELS ARENT RIGHT

Question 4

Hypo-k causes

Answer 4

alcholism
malnutrition
diurtics
direhha
vomiting for long time
insulin admistration 
Mg def
DKA- diabetic ketoacidosis- this is treated with insulin and when glu goes into the cell so does K so that changes levels outside

Question 5

hypo- K manifestations

Answer 5

k function- think muscles so if muscles dont have enough k think they wont work as well.
bradycardia
cardiac dysrthymias
shollow breath bc the chest muscles dont work that well

Question 6

hyper k casues

Answer 6

Shift of the K from ICF to ECF. remeber this is acidosis

renal failure- cannot get enough out in pee
hyperglemica- not enough insulin rmbr k goes into cell with glu
alot of blood transfustions
aldosterone deficit becasue alodstrone swaps K with Na in kideny and excreates K

Question 7

hyper K manisfestations

Answer 7

think muscle over activity - tingling of lips and fingers
restlessness
cramping in stomach (smooth muscle over reacing)
cardiac dyrthymias

Question 8

treatments for hyper K

Answer 8

kaexlate- via feces can cause dirreha
IV ca
bicarb bc it promotes K to move intothe cell
