Question

Chapter 13: Respiratory System Disorders Case Studies Case Study 1 Mr. F, age 46 years, has had a persistent unproductive cough for several months that did not respond to cough medications. Recently, he has developed a productive cough accompanied by fatigue, anorexia, and night sweats. Examination indicated abnormal chest sounds and weight loss. A chest radiograph showed a small cavity and infiltrate, the tuberculin test was positive, and the sputum sample contained a small amount of blood and numerous acid-fast bacilli, confirming the diagnosis of active tuberculosis. Discussion Questions 1. Discuss the pathologic changes occurring during the development of active tuberculosis. (See Tuberculosis.) 2. Discuss the transmission of TB and the conditions predisposing to the development of TB. (See Tuberculosis-Diagnostic Tests.) 3. Discuss the treatment of tuberculosis and the precautions involved for health care personnel coming into contact with the patient. (See Tuberculosis-Treatment.) 4. Suggest how family members or co-workers can protect themselves.

Answer 1

Tuberculosis is a disease which is caused by Mycobacteria. These microbes gets in to lungs of the person from the infected person. These bacteria multiply themselves and causes the infection to be spread in the lungs. This causes increased fluid accumulation in the lungs.

Tuberculosis is transmitted from the infected person's droplets of cough. When a normal person inhale these droplets causes infection as they contain bacteria. The duration of the exposure of the susceptible person increases the risk of infection.

Treatment of the tuberculosis includes bacteriocidal and bacteriostatic effects. The drugs are involved such as:

• Isoniazid
• Rifampicin
• Pyrazinamide
• Ethambutol.

Family members can protect themselves by wearing mask, not using infected clothes of the person, maintaining personal hygiene.
