Answer to Question 1

Ans:
B, D, E, F

Feedback:

Pregnancy, BPH, renal calculi, and neurogenic bladder are all identified contributors to urinary obstructions. Acid-base imbalances and impaired erythropoietin production are health problems with renal involvement but are less likely to contribute to urinary obstruction.

Answer to Question 2

Ans:
A, D

Feedback:

The first layer performs numerous functions. These include production of mucus that lubricates and protects the inner surface of the alimentary canal; secretion of digestive enzymes and substances that break down food; absorption of the breakdown products of digestion; and maintenance of a barrier to prevent the entry of noxious substances and pathogenic organism. The facilitation of movement of contents of the GI tract occurs in the third layer while holding the organs in place, and storage of fats occurs in the fourth layer.
