A client with TB is prescribed a combination of medications. What is the rationale for using multiple drugs to treat TB?

To reduce the cost of treatment.

To minimize the risk of drug resistance.

To achieve a quicker cure.

To avoid potential drug interactions.

Answer and Explanation

The Correct Answer is B

Choice A rationale:

Using multiple drugs to treat TB is not primarily done to reduce the cost of treatment. While cost considerations are essential in healthcare, the main reason for employing multiple drugs is to prevent drug resistance and improve treatment outcomes.

Choice B rationale:

The rationale for using multiple drugs to treat TB is to minimize the risk of drug resistance. TB is caused by Mycobacterium tuberculosis, and the bacteria can develop resistance to single-drug treatments quite rapidly. Using a combination of drugs with different mechanisms of action makes it harder for the bacteria to become resistant to all drugs simultaneously, ensuring a more effective treatment.

Choice C rationale:

While using multiple drugs may help achieve a quicker cure, the primary reason for combining drugs in TB treatment is to prevent drug resistance. Faster cure is a secondary benefit, but the prevention of drug-resistant strains is of paramount importance in TB management.

Choice D rationale:

Avoiding potential drug interactions is an essential consideration in any medical treatment, but it is not the primary reason for using multiple drugs in TB treatment. The main focus is on preventing drug resistance and increasing treatment success.

Correct Answer is C

Explanation

Choice A rationale:

Chemoprophylaxis involves using medications to prevent TB infection or its progression in individuals at high risk of exposure. While it is an important strategy, it is not specifically related to administering the BCG vaccine.

Choice B rationale:

Screening for TB involves identifying individuals who are at risk of infection or have active disease through various tests such as tuberculin skin tests and chest X-rays. Although screening is a crucial aspect of TB control, it is not the strategy involving BCG vaccine administration.

Choice C rationale:

Vaccination with the BCG vaccine is an individual-level strategy aimed at providing protection against TB, particularly in infants or children at high risk of TB exposure or infection. The BCG vaccine does not provide complete protection against TB but has been shown to reduce the risk of severe forms of the disease, such as TB meningitis and miliary TB, in children.

Choice D rationale:

Surveillance involves monitoring the incidence and prevalence of TB at the population level. It does not directly involve administering the BCG vaccine to individuals at risk.

A. Abdominal pain. B. Headache. C. Hematuria. D. Cough.

Correct Answer is D

Explanation

Choice A rationale:

Abdominal pain is not commonly associated with tuberculosis (TB) TB primarily affects the lungs, and symptoms such as cough, fever, weight loss, and night sweats are more typical of TB.

Choice B rationale:

Headache is not a common symptom of TB. While TB can cause systemic symptoms like fever and fatigue, it does not typically cause headaches unless there are complications involving the central nervous system, which is relatively rare.

Choice C rationale:

Hematuria, which is the presence of blood in the urine, is not a symptom commonly associated with TB. TB primarily affects the respiratory system and is not known to cause urinary symptoms.

Choice D rationale:

Cough is a hallmark symptom of tuberculosis. It is usually a productive cough that lasts for several weeks or longer, with the possibility of producing sputum that may be bloody or purulent. Cough is a key indicator for healthcare providers to suspect TB and order appropriate testing.
