A nurse is explaining directly observed therapy (DOT) to a client with active TB disease. What is the purpose of DOT?

To reduce the risk of resistance, relapse, or transmission.

To facilitate early diagnosis and treatment.

To evaluate the impact and effectiveness of TB control programs.

To identify and test persons who have been in close contact with active TB cases.

Answer and Explanation

The Correct Answer is A

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.

Correct Answer is ["A","B","E"]

Explanation

Choice A rationale:

Covering the mouth and nose when coughing or sneezing is an essential measure to prevent the transmission of TB. TB is spread through airborne droplets, and covering the mouth and nose helps contain these droplets, reducing the risk of transmission to others.

Choice B rationale:

Using an N95 respirator mask is necessary when caring for patients with suspected or confirmed TB. N95 masks provide a high level of filtration and help protect healthcare workers and others from inhaling TB bacteria.

Choice C rationale:

Placing the patient in a negative pressure room is a measure used for patients with suspected or confirmed active TB disease. Negative pressure rooms help prevent the spread of infectious particles to the surrounding environment.

Choice D rationale:

Encouraging physical activity is not directly related to preventing TB transmission. While physical activity is beneficial for overall health, it does not play a significant role in preventing the transmission of TB.

Choice E rationale:

Washing hands frequently is an essential measure to prevent the transmission of TB and other infections. Proper hand hygiene reduces the risk of spreading bacteria from contaminated surfaces to the mouth, nose, or eyes.

A. Observation for disease progression. B. Sputum smear microscopy. C. Tuberculin skin test (TST) D. INH administration. E. Contact tracing.

Correct Answer is ["A"]

Explanation

Choice A rationale:

The most appropriate intervention for a client diagnosed with latent TB infection (LTBI) is observation for disease progression. Latent TB infection means that the individual has been infected with the tuberculosis bacteria but does not currently have active TB disease. In cases of LTBI, the bacteria are in a dormant state, and the person does not show any symptoms. The standard approach for LTBI management is to monitor the individual closely for any signs of disease progression. This may involve regular clinical assessments and follow-ups to detect the development of active TB. Initiating treatment (such as INH administration) is not recommended for all individuals with LTBI, as not everyone with latent infection will progress to active disease. The decision to treat depends on the individual's risk factors, clinical presentation, and other considerations. Selecting choice B (Sputum smear microscopy) is not appropriate for LTBI since this test is used to diagnose active TB disease, not latent infection. Choice C (Tuberculin skin test, TST) is used to identify individuals with LTBI, not as an intervention for those already diagnosed with LTBI. Choice D (INH administration) may be a treatment option for certain individuals with LTBI, but it is not the most appropriate intervention for all LTBI cases. Choice E (Contact tracing) is a strategy to identify and screen individuals who may have been exposed to active TB cases, not a direct intervention for LTBI management.
