Answer to Question 1

Correct Answer: 3
Rationale 1: The gallbladder stores bile.
Rationale 2: The teeth help to break down food substances.
Rationale 3: The overall function of the liver is to filter and process nutrients and drugs delivered to it. Substances can be stored, chemically altered, or removed from the blood before they reach the general circulation.
Rationale 4: The duodenum is not an accessory organ.
Global Rationale: The liver has the most pharmacologic importance of the organs listed. The gallbladder is a storage unit and can be removed. Teeth are replaceable. The duodenum is not an accessory organ.

Answer to Question 2

Correct Answer: 2,4
Rationale 1: Normal flora is not required to synthesize vitamin A.
Rationale 2: Normal flora is required to synthesize vitamin B-complex.
Rationale 3: Normal flora is not required to synthesize vitamin C.
Rationale 4: Normal flora is required to synthesize vitamin K.
Rationale 5: Normal flora is not required to synthesize electrolytes.
Global Rationale: The colon harbors a substantial amount of bacteria and fungi, called the host flora, which serve a useful purpose by synthesizing B-complex vitamins and vitamin K. Disruption of the normal host flora can lead to diarrhea. This flora is not required to synthesize vitamin A, vitamin C, or electrolytes.
