After administering an antineoplastic drug, the nurse bases the ongoing assessment on which of the following factors?

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.

Choice A rationale:

Alkylating agents are cell cycle-specific drugs. They work on cells during various stages of the cell cycle and are classified as cell cycle phase-nonspecific drugs. These drugs form covalent bonds with DNA, preventing DNA replication and transcription. This action disrupts the cell cycle, making them effective against actively dividing cells.

Choice B rationale:

Plant alkaloids are not cell cycle-specific drugs. Plant alkaloids, such as vinblastine and vincristine, are derived from plants and are classified as cell cycle phase-specific drugs. They primarily affect cells during the M phase of the cell cycle by disrupting microtubule formation. While they are effective against rapidly dividing cells, they are not cell cycle-specific.

Choice C rationale:

Antineoplastic antibiotics are not cell cycle-specific drugs. These drugs, such as doxorubicin and daunorubicin, are used in cancer treatment and primarily work by intercalating with DNA and inhibiting topoisomerase enzymes. Their mechanisms of action do not specifically target a particular phase of the cell cycle, making them cell cycle phase-nonspecific.

Choice D rationale:

Retinoids are not cell cycle-specific drugs. Retinoids are derived from vitamin A and have various mechanisms of action, including regulating cell growth and differentiation. They are not classified as cell cycle-specific drugs.
