A nurse needs to administer a cephalosporin to a patient.
The patient informs the nurse that he is allergic to penicillin.
Which action by the nurse would be most appropriate?

Choice A rationale:

The goal of having the client state adverse reactions to report is important, but it is not the primary goal of antitubercular therapy. The main objective is to ensure that the client and their family understand the drug regimen to promote adherence and successful treatment. This is crucial in preventing drug-resistant tuberculosis and achieving the desired outcome.

Choice B rationale:

Maintaining adequate nutritional status is essential for overall health, but it is not the primary goal of antitubercular therapy. While good nutrition can support the immune system, the central goal should be related to medication adherence and preventing the spread of tuberculosis.

Choice D rationale:

Client managing the therapeutic regimen effectively is an important aspect of tuberculosis treatment, but this choice lacks the emphasis on educating the client and their family about the drug regimen, which is a fundamental component of successful therapy.

Choice E rationale:

The negative sputum culture is an indicator of treatment success, but it's more of an outcome measure than a goal for the client. The primary goal should focus on education and adherence to the drug regimen.

Choice A rationale:

Administering a combination of drugs in TB treatment is not primarily aimed at preventing the incidence of liver dysfunction. The combination therapy's main objective is to address the complex nature of Mycobacterium tuberculosis infections and the potential development of antibiotic resistance.

Choice B rationale:

The nurse should explain that the primary reason for administering a combination of drugs is to slow down bacterial resistance. When TB is treated with a single drug, the bacteria can quickly develop resistance to that drug. Using a combination of drugs with different mechanisms of action makes it more difficult for the bacteria to develop resistance. This is a fundamental principle in the treatment of TB.

Choice C rationale:

Slowing the body's resistance to medication is not a goal in TB treatment. The focus is on preventing the development of resistance in the bacteria, not the body's response to the medication.

Choice D rationale:

While TB treatment aims to prevent the further spread of the disease, the primary reason for using a combination of drugs is to address bacterial resistance. Preventing the spread of TB is an important secondary benefit of effective treatment.
