Q

The reduction of minteralcorticoids caused by 21-hydroxylase deficiency causes the activation of what system?

A

renin-angiotensin system is activated due to hypotension from salt wasting; thus, angiotensin II levels are elevated

Q

In what way can squamous cell carcinoma cause hypercalcemia?

Q

Hyperglycemia is a common cause of what type of electrolyte imbalance? how does it occur?

A

hypertonic hyponatremia; since glucose is osmotically active, it acts as a concentrated solute in the extracellular compartment and draws water from the intracellular compartment, this causes a drop in sodium

Diuretics, esp. thiazide diuretics is one of the principle causes of what type of electrolyte imbalance? how does it occur?
