Answer 1

recording of the electrical activity of the heart

Question 2

EEG

Answer 2

a painless procedure that uses small, flat metal discs (electrodes) attached to your scalp to detect electrical activity in your brain

Question 3

Answer 3

Creatinine, BUN, GFR

Question 4

o Creatinine-

Answer 4

0.6 – 1.2 mg/dL; muscle breakdown protein; filtered, but not reabsorbed, so blood and urine levels can be used to estimate GFR

Question 5

o BUN-

Answer 5

10-20 mg/dL; Increases related to increased protein intake, kidney damage, low fluid intake; decreases related to poor diet, malabsorption, low nitrogen intake

Question 6

o GFR-
