  C)
  Acidosis causes an increase in K+ elimination.
  D)
  Alkalosis tends to increase H+ elimination.

Question 2

Answer to Question 1

Ans:
A

Feedback:

Hypokalemia is a potent stimulus for H+ secretion and HCO3 reabsorption. Acidosis tends to increase H+ elimination and decrease K+ elimination, with a resultant increase in plasma potassium levels, whereas alkalosis tends to decrease H+ elimination and increase K+ elimination, with a resultant decrease in plasma K+ levels.

Answer to Question 2

Ans:
A

Feedback:

SIADH manifests as a dilutional hyponatremia. Decrease urine output, absence of edema, and headaches are signs of this. Answer choice B relates to s/s of diabetes insipidus; answer choice C is indicative of common flu s/s; answer choice D is relates to s/s of hypocalcemia.
