A nurse is caring for a client with iron deficiency anemia who is receiving iron supplements.
What information should the nurse include in the teaching plan for this client?

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.

Choice A rationale:

Protease inhibitors are a category of antiretroviral drugs used in the treatment of HIV. They work by affecting an enzyme called protease, which is necessary for the maturation of new viral particles. By inhibiting protease, these drugs prevent the formation of mature, infectious HIV particles.

Choice B rationale:

Reverse transcriptase inhibitors, including both nucleoside and non-nucleoside variants, target the enzyme reverse transcriptase. This enzyme is involved in the conversion of HIV RNA into DNA, an essential step in the viral life cycle. However, it's not about preventing the maturation of new viral particles, as mentioned in the question.

Choice C rationale:

Nonnucleoside reverse transcriptase inhibitors (NNRTIs) also inhibit the reverse transcriptase enzyme, but they do so differently than protease inhibitors. While they are vital in HIV treatment, they do not specifically target the maturation of viral particles.

Choice D rationale:

Integrase inhibitors target the enzyme integrase, which is involved in the integration of viral DNA into the host cell's DNA. This step is crucial in the HIV life cycle, but it's not related to the maturation of new viral particles.
