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.
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:
Providing emotional support and counseling is an important aspect of nursing care for TB patients. However, the primary goal of nursing interventions is to address the transmission of the disease and prevent its spread to others. TB is a highly contagious airborne disease, and healthcare professionals play a crucial role in implementing measures to reduce transmission.
Choice B rationale:
Monitoring the patient's weight and vital signs is essential for assessing the patient's response to treatment and overall health status. While these interventions are important, they are not the primary goal for TB patients. The main focus remains on preventing transmission and ensuring effective treatment.
Choice C rationale:
Preventing transmission of TB is the primary goal of nursing interventions. This involves implementing infection control measures, such as respiratory isolation, proper use of personal protective equipment, and education on cough etiquette for patients. By preventing the spread of TB, healthcare professionals contribute to public health efforts to control the disease.
Choice D rationale:
Administering antibiotic therapy is a critical aspect of TB treatment. However, it is not the primary goal of nursing interventions. Nursing interventions primarily focus on the prevention of transmission and supporting patients through their treatment journey.
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.
