A patient with TB is undergoing initial therapy in the treatment.
The nurse has to administer three or more drugs in combination to the patient.
The patient wishes to know the reason for administering a combination of drugs.
Which of the following explanations does the nurse offer related to the combination of medications?

Prevents the incidence of liver dysfunction.

Slows down bacterial resistance.

Slows the body's resistance to medication.

Prevents further spreading of TB.

Answer and Explanation

The Correct Answer is B

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.

Correct Answer is B

Explanation

Choice A rationale:

Staphylococcus is not typically associated with causing diarrhea or harm to the intestinal mucosa. Staphylococcus is more commonly linked to skin and soft tissue infections, as well as food poisoning.

Choice B rationale:

Salmonella is a bacterium that can harm the intestinal mucosa and is a common cause of foodborne illness. It can lead to symptoms such as diarrhea, abdominal pain, fever, and vomiting, which can be severe and potentially damage the intestinal lining.

Choice C rationale:

Streptococcus is not a common cause of diarrhea or harm to the intestinal mucosa. Streptococcus species are more often associated with respiratory and throat infections.

Choice D rationale:

Pseudomonas is not a typical cause of diarrhea or harm to the intestinal mucosa. Pseudomonas is known for its association with healthcare-associated infections and is more often linked to conditions like pneumonia and urinary tract infections.

A. Frequency of urination will increase. B. Soreness of throat might occur. C. Itching of throat might occur. D. Color of stools will become darker.

Correct Answer is C

Explanation

Choice A rationale:

Frequency of urination increasing is not typically associated with iron supplements. Iron supplements are more likely to cause constipation or darkening of stools due to increased iron content in the stool.

Choice B rationale:

Soreness of the throat is not a common side effect of iron supplements. While iron supplements can sometimes cause gastrointestinal discomfort, sore throat is not a usual manifestation.

Choice C rationale:

Itching of the throat might occur when taking iron supplements. Iron can irritate the gastrointestinal tract, and this irritation may extend to the throat, causing mild itching or discomfort.

Choice D rationale:

The color of stools becoming darker is a common side effect of iron supplements. Iron can darken stools and make them appear black, which is known as "black, tarry stools.”. This is due to the unabsorbed iron in the gastrointestinal tract.
