Answer to Question 1

Ans:
B

Feedback:

In the kidney, PTH stimulates tubular reabsorption of calcium while reducing the reabsorption of phosphate. The latter effect ensures that increased release of phosphate from bone during mobilization of calcium does not produce an elevation in serum phosphate levels.

Answer to Question 2

Ans:
A

Feedback:

While displacement of the uterus, bladder, and rectum can result in uterine prolapse, cystocele, and rectocele, the peritoneum is unlikely to prolapse into the vagina.
