Quiz on Tuberculosis

Tuberculosis is primarily transmitted through which route?

• Contaminated food and water

• Sexual contact

• Airborne droplets

• Contact with infected skin lesions

Which of the following populations is at highest risk for developing active TB disease?

• Healthy young adults

• Individuals with well-controlled diabetes

• Immunocompromised individuals (e.g., HIV-positive)

• People living in rural areas with good sanitation

A hallmark symptom of pulmonary tuberculosis is:

• Acute onset fever and chills

• Productive cough lasting less than one week

• Chronic cough (often more than 2-3 weeks) with or without sputum

• Sudden severe headache and stiff neck

The standard diagnostic test for pulmonary tuberculosis, involving microscopic examination of sputum, is:

• Blood culture

• Sputum Acid-Fast Bacilli (AFB) smear

• Throat swab culture

• Urine analysis

Which diagnostic imaging technique is crucial for assessing lung involvement in suspected pulmonary TB?

• MRI of the brain

• Abdominal ultrasound

• Chest X-ray

• Bone scan

First-line anti-tuberculosis drugs typically include all of the following EXCEPT:

• Isoniazid

• Rifampicin

• Ethambutol

• Amoxicillin

The recommended duration of treatment for drug-susceptible pulmonary tuberculosis is typically:

• 2 weeks

• 1 month

• 6-9 months

• 2 years

What is the main purpose of directly observed treatment, short-course (DOTS) in TB management?

• To reduce the cost of medication

• To ensure patient adherence and prevent drug resistance

• To accelerate the diagnostic process

• To provide nutritional support to patients

Drug resistance in tuberculosis, particularly Multi-Drug Resistant TB (MDR-TB), is primarily caused by:

• Over-prescription of antibiotics

• Incomplete or irregular treatment of drug-susceptible TB

• Exposure to different strains of Mycobacterium tuberculosis

• Eating contaminated food

Preventing the spread of TB in healthcare settings involves all of the following EXCEPT:

• Isolation of patients with suspected or confirmed TB

• Use of personal protective equipment (e.g., N95 masks)

• Ensuring proper ventilation in patient rooms

• Routine prophylactic antibiotic use for all healthcare workers
