How does drug therapy of tuberculosis differ from that of most other infections?
Patients with tuberculosis have no symptoms.
Antituberculosis drugs are used extensively for treating active disease, not prevention.
Patients usually require therapy for a shorter period.
Mycobacteria have a cell wall that is resistant to penetration by anti-infective drugs.
The Correct Answer is D
Choice A rationale
While it’s true that some people with tuberculosis (TB) may not have symptoms (a condition known as latent TB), many people with active TB do have symptoms. Symptoms can include a cough that lasts more than three weeks, pain in the chest, and coughing up blood or sputum.
Choice B rationale
Antituberculosis drugs are indeed used extensively for treating active TB disease. However, they are also used in some cases for prevention, such as in people who have been exposed to TB or who have latent TB4.
Choice C rationale
Treatment for TB usually requires a much longer period than treatment for most other infections. TB treatment can take from 6 to 9 months or even longer, especially for drug- resistant TB45.
Choice D rationale
Mycobacteria, the bacteria that cause TB, do have a cell wall that is resistant to penetration by many anti-infective drugs. This is one reason why TB requires a long treatment period with a combination of drugs.

Correct Answer is C
Explanation
Choice A rationale
While monitoring BUN (Blood Urea Nitrogen) levels can provide information about kidney function and hydration status, it is not specifically related to the use of isoniazid (INH) for tuberculosis treatment.
Choice B rationale
PT (Prothrombin Time) and PTT (Partial Thromboplastin Time) are tests that measure the time it takes for blood to clot. These tests are not specifically related to the use of isoniazid (INH) for tuberculosis treatment.
Choice C rationale
Liver enzymes (LFTs) should be monitored in patients taking isoniazid (INH) because this medication can cause hepatotoxicity, or liver damage. Regular monitoring of liver enzymes can help detect this potential side effect early.
Choice D rationale
While a CBC (Complete Blood Count) can provide important information about a patient’s overall health, it is not specifically related to the use of isoniazid (INH) for tuberculosis treatment.
Correct Answer is C
Explanation
Choice A rationale
Antidepressants are a class of medications used to treat depression and other mood disorders, not primarily for their sedative and anti-seizure effects.
Choice B rationale
Anxiolytics are medications that inhibit anxiety. They are used to treat anxiety disorders and relieve short-term anxiety symptoms. While some anxiolytics do have sedative effects, they are not derived from barbituric acid.
Choice C rationale
Barbiturates are a class of drugs derived from barbituric acid that act as depressants to the central nervous system. These drugs are used as sedatives or anesthetics and have the potential to become addictive.
Choice D rationale
Benzodiazepines are a class of psychoactive drugs used to treat a range of conditions, including anxiety and insomnia. They are known for their sedative and anxiolytic effects. However, they are not derived from barbituric acid.
