32

What is the most common causes of secondary hyperparathyroidism because of the resulting hyperphosphatemia that stimulates PTH secretion?

chronic renal failure

33

In hypothyroidism, a lack of circulating PTH causes a _____ resulting in the symptomatology.

depressed serum calcium level

34

A man with diabetic ketoacidosis (DKA) has the following lab values: arterial pH 7.20; serum glucose 500 mg/dL; urine glucose and ketones positive; serum K+ 2 mEq/L; serum Na+ 130 mEq/L. He reports that he has been sick with the "flu" for 1 wk. What do you suspect is his problem?

decreased glucose use
- this causes increase in fatty acid use, ketogenesis, metabolic acidosis, and osmotic diuresis all of which he has.
