Answer to Question 1

Correct Answer: 3
Rationale 1: Mycobacterium tuberculosis is not spread through sexual transmission. This is true of HIV and HPV.
Rationale 2: Mycobacterium tuberculosis is not spread by the fecal/oral route. This is true of hepatitis A.
Rationale 3: Mycobacterium tuberculosis is spread by the respiratory route.
Rationale 4: Mycobacterium tuberculosis is not spread by hand-to-hand contact.
Global Rationale: Mycobacterium tuberculosis is spread by the respiratory route. Sexual, fecal/oral, and hand-to-hand are not routes of transmission.

Answer to Question 2

Correct Answer: 2
Rationale 1: The substance that protects Mycobacterium is not polysaccharides.
Rationale 2: This answer is correct; the substance that protects Mycobacterium is mycolic acid.
Rationale 3: The substance that protects Mycobacterium is not yeast.
Rationale 4: The substance that protects Mycobacterium is not acetylation.
Global Rationale: The pharmacotherapy of TB differs from that of other bacterial infections because the thick mycolic acid layer surrounding the mycobacterium is resistant to penetration by anti-infectives. There is no protection from polysaccharides, yeast, or acetylation.
