Answer to Question 1

Ans:
B

Feedback:

The process described is direct antigen detection, which can indirectly implicate a microorganism that is unable to be cultured. Answer D describes the same process in reverse, while answers A and C do not describe existing diagnostic processes.

Answer to Question 2

Ans:
B

Feedback:

Muscle atrophy, protein breakdown, and decalcification of bone produce hypercalcemia and hyperphosphatemia in clients on bed rest. PTH tends to increase and insulin tends to decrease.
