A 72-year-old patient with TB is undergoing standard treatment in a health care facility.
Which ongoing assessment would the nurse complete?
Monitoring for the appearance of adverse reactions.
Monitoring the patient's vital signs every 24 hours.
Assessing the patient's history of contacts.
Use DOT to administer the drug to the patient.
The Correct Answer is A
Choice A rationale:
Monitoring for the appearance of adverse reactions is a crucial aspect of managing a patient with TB undergoing treatment. TB medications can have side effects, and early detection of adverse reactions is essential for timely intervention. Some common adverse effects of TB drugs include hepatotoxicity, peripheral neuropathy, and gastrointestinal disturbances. By closely monitoring the patient, the nurse can ensure prompt action if these side effects occur, improving the patient's overall care and safety.
Choice B rationale:
Monitoring the patient's vital signs every 24 hours may be part of standard nursing care, but when managing a patient with TB, the primary focus should be on monitoring for adverse reactions to the TB medications. Vital signs are important but not the most critical aspect of care in this specific situation.
Choice C rationale:
Assessing the patient's history of contacts is essential for identifying potential sources of TB transmission. However, it is more related to the initial assessment and diagnosis of TB rather than ongoing assessment during treatment. The primary focus during treatment is monitoring the patient's response to medication and any adverse reactions.
Choice D rationale:
Using Directly Observed Therapy (DOT) to administer TB drugs is a standard practice to ensure treatment adherence. However, ongoing assessment should focus on monitoring for adverse reactions and treatment effectiveness rather than the administration method, which is usually established at the beginning of treatment.

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.
Correct Answer is A
Explanation
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.
