Drug therapy of tuberculosis differs from that of most other infections because:

Patients usually require therapy for a shorter period

Patients with tuberculosis have no symptoms

Mycobacteria have a cell wall that is resistant to penetration by anti-infective drugs

Anti-tuberculosis drugs are used extensively for treating active disease, not preventing it

Answer and Explanation

The Correct Answer is C

A. Patients usually require therapy for a shorter period: This is incorrect. TB therapy typically lasts for several months, longer than most other bacterial infections.
B. Patients with tuberculosis have no symptoms: This is incorrect. Many patients with active TB do exhibit symptoms such as cough, fever, night sweats, and weight loss.
C. Mycobacteria have a cell wall that is resistant to penetration by anti-infective drugs: This is correct. The mycobacterial cell wall is complex and impermeable, requiring specialized drugs and prolonged treatment.
D. Anti-tuberculosis drugs are used extensively for treating active disease, not preventing it: This is partially true, but TB drugs are also used for latent TB infection to prevent it from becoming active. Thus, it is not a primary reason differentiating TB therapy from other infections.

Correct Answer is B

Explanation

A. Diarrhea: Diarrhea is a common side effect of antibiotics due to their effect on the gut microbiota, but it is not typically indicative of an allergy.
B. Hives or shortness of breath: Hives (urticaria) and shortness of breath are classic symptoms of an allergic reaction. Hives indicate an immediate hypersensitivity reaction, and shortness of breath can indicate a serious allergic reaction such as anaphylaxis. These symptoms warrant caution and further assessment before starting antimicrobial therapy.
C. Headaches: Headaches can be a side effect of various medications but are not a specific sign of a drug allergy.
D. Nausea: Nausea is a common side effect of many medications, including antibiotics, but it does not specifically indicate an allergic reaction.

A. Ketoacids B. Hyperglycemia C. Hypoglycemia D. Glucagon

Correct Answer is B

Explanation

A. Ketoacids: This is incorrect. While ketoacids are a by-product of fat metabolism that occurs when insulin is low, they do not directly stimulate insulin secretion.
B. Hyperglycaemia: This is correct. Elevated blood glucose levels (hyperglycaemia) directly stimulate the pancreas to secrete insulin to help lower blood glucose levels.
C. Hypoglycaemia: This is incorrect. Low blood glucose levels (hypoglycaemia) would reduce insulin secretion and might increase glucagon secretion to raise blood glucose levels.
D. Glucagon: This is incorrect in the context of directly stimulating insulin secretion. Glucagon is a hormone secreted by the alpha cells of the pancreas when blood glucose levels are low. Its primary role is to increase blood glucose levels by stimulating glycogenolysis and gluconeogenesis in the liver.
