A nursing instructor is describing a situation in which a client with tuberculosis periodically visits his primary health care provider and demonstrates taking his medication in front of the nurse.
The instructor is describing which of the following?

Initial phase of treatment.

Continuation phase of treatment.

Directly observed therapy.

Adherence evaluation.

Answer and Explanation

The Correct Answer is C

Choice A rationale:

The initial phase of treatment in tuberculosis management involves the first few weeks of intensive drug therapy when the goal is to reduce the bacterial load and prevent drug resistance. During this phase, the client typically takes multiple medications, but there is no requirement for direct observation by a healthcare provider.

Choice B rationale:

The continuation phase of treatment occurs after the initial phase in tuberculosis management. It focuses on preventing relapse and the complete eradication of the bacteria. During this phase, the client takes fewer medications, but there is no direct observation of medication administration.

Choice C rationale:

Directly observed therapy (DOT) is a strategy used in tuberculosis treatment where a healthcare provider or trained observer directly watches the client take their medications. This is particularly important to ensure adherence and prevent drug resistance. The description in the question aligns with the practice of DOT.

Choice D rationale:

Adherence evaluation refers to assessing how well a client follows their treatment plan, but it doesn't necessarily involve observing medication administration. While adherence evaluation is essential, the scenario described in the question specifically mentions the client demonstrating medication intake in front of a nurse, which corresponds to DOT.

Correct Answer is A

Explanation

Choice A rationale:

Bacteriostatic. Sulfonamides are a class of antibiotics that work primarily as bacteriostatic agents. They inhibit the growth and reproduction of bacteria by blocking the synthesis of folic acid, which is essential for bacterial DNA and RNA synthesis. By slowing down bacterial growth, sulfonamides give the body's immune system a chance to eliminate the bacteria. Bacteriostatic antibiotics do not directly kill bacteria but rather impede their ability to multiply. This action is a key characteristic of sulfonamides.

Choice B rationale:

Bactericidal. Sulfonamides are not primarily bactericidal. Bactericidal antibiotics directly kill bacteria by disrupting their cell walls, protein synthesis, or other essential processes. Sulfonamides do not have this direct killing effect. They work by inhibiting folic acid synthesis and, as a result, slowing down bacterial growth. While this can eventually lead to bacterial death, the primary action of sulfonamides is bacteriostatic.

Choice C rationale:

Promotor of folic acid activity. This choice is not accurate. Sulfonamides do not promote folic acid activity; rather, they inhibit it. Sulfonamides are structural analogs of para-aminobenzoic acid (PABA), a precursor necessary for folic acid synthesis in bacteria. By competing with PABA, sulfonamides disrupt folic acid production in bacteria, ultimately leading to growth inhibition. Therefore, they are not promoters of folic acid activity.

Choice D rationale:

Bacterial cell metabolizer. Sulfonamides do not metabolize bacterial cells. Instead, they interfere with bacterial metabolism by blocking the synthesis of folic acid. This disruption affects the DNA and RNA synthesis of bacteria, which rely on folic acid derivatives. The primary action of sulfonamides is to inhibit this metabolic pathway, not to metabolize bacterial cells.

A. Client's general condition. B. Type and location of neoplastic lesion. C. Previous or concurrent treatment. D. Anxiety or fears that the patient may have. E. Patient's understanding of proposed treatment regimen.
