A client with latent TB infection (LTBI) is prescribed chemoprophylaxis. Which statement by the client indicates understanding of the treatment regimen?

Choice A rationale:

Young adults between 20 to 30 years of age are at a higher risk of developing tuberculosis (TB) compared to other age groups. This age range often includes individuals who may be exposed to TB in various settings, such as college or university students, individuals in the workforce, and those who may engage in behaviors that increase the risk of TB transmission, such as socializing in crowded places.

Choice B rationale:

Children under the age of 5 are also considered a high-risk group for TB, especially in regions with a high prevalence of the disease. However, in many settings, young adults between 20 to 30 years of age have shown higher rates of TB infection and disease compared to young children.

Choice C rationale:

Elderly individuals over the age of 65 are generally considered at higher risk for developing severe complications from TB, but their risk of primary TB infection is lower compared to younger age groups, including young adults between 20 to 30 years of age.

Choice D rationale:

Pregnant women, like the elderly, are at higher risk of severe complications if they develop TB during pregnancy. However, the incidence of TB is generally lower in pregnant women compared to young adults between 20 to 30 years of age, who are more socially active and likely to encounter TB-exposed individuals.

Choice A rationale:

Directly observed therapy (DOT) is a treatment strategy used for clients with active tuberculosis (TB) disease. The purpose of DOT is to ensure that the client takes their TB medications as prescribed, under direct observation by a healthcare provider or trained healthcare worker. By directly observing the medication administration, DOT helps to ensure medication adherence, which is crucial in preventing the development of drug-resistant TB strains. It also reduces the risk of treatment failure, relapse of the disease, and transmission of TB to others. By closely monitoring the client's adherence to the treatment regimen, healthcare providers can intervene promptly if any issues arise during the course of treatment.

Choice B rationale:

Facilitating early diagnosis and treatment is an essential aspect of TB control; however, this is not the primary purpose of directly observed therapy (DOT) Early diagnosis helps to identify and initiate appropriate treatment promptly, but DOT is specifically implemented to monitor and enhance adherence during the course of treatment, particularly for those at risk of non-compliance.

Choice C rationale:

Evaluating the impact and effectiveness of TB control programs is an important public health measure, but it is not the direct purpose of DOT. DOT mainly focuses on individual client treatment adherence rather than assessing overall program effectiveness.

Choice D rationale:

Identifying and testing persons who have been in close contact with active TB cases is part of contact tracing and TB screening efforts, which are separate from the purpose of directly observed therapy (DOT) DOT is centered on the supervision of treatment for clients already diagnosed with active TB disease.
