and magnesium
46. describe potassium's effect on the heart - CORRECT ANSWER hypokalemia
delays repolarization leading to AV block and decreased skeletal muscle
movement, potential respiratory arrest
47. hyperkalemia- shortened repolarization- fibrillation, muscle weakness, possible
paralysis
48. which electrolyte can be used to treat hyperkalemia and why? - CORRECT
ANSWER calcium- it stabilizes membrane potential
49. describe the effect of PTH on calcium - CORRECT ANSWER PTH pulls
calcium from bone to increase amount in plasma

magnesium blocks calcium uptake in cells leading to smooth muscle relaxation-
anticonvulsant

water from the lungs and H and HCO3 from the kidneys
56. what is the kidneys response to acidosis? - CORRECT ANSWER they release
hydrogen ions to preserve bicarb
