Answer to Question 1

Correct Answer: 4
Rationale 1: One month is not long enough.
Rationale 2: Seven days are not long enough.
Rationale 3: Fourteen days are not long enough.
Rationale 4: The required length of therapy can be 6 to 12 months.
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. For the drugs to reach the mycobacteria isolated in tubercles and inside macrophages, therapy must continue for 6 to 12 months.

Answer to Question 2

Correct Answer: 1
Rationale 1: These organs are the sites of infection in the postprimary stage.
Rationale 2: The skin and muscles are not the organs affected in the postprimary stage.
Rationale 3: The bowel and liver are not the most common areas affected in the postprimary stage.
Rationale 4: The heart and blood vessels are not affected in the postprimary stage.
Global Rationale: If the immune system becomes suppressed later in life, the dormant mycobacteria may enter a postprimary or reactivation stage. Once reactivated, M. tuberculosis can be disseminated throughout the body via the blood or lymphatic system. Lymph nodes and organs of the genitourinary system are the most common nonrespiratory sites, although infections of the bone marrow and liver are possible. Skin, muscles, heart, and blood vessels are not commonly affected.
