Question

Question

Answer 1

Correct Answer: Five

Rationale:

The number of adult weight band categories for treatment of TB is five. These weight bands are essential to ensure that patients receive the correct dosages of medications based on their body weight, which helps in the effective treatment of tuberculosis.
The five weight bands typically used are: 30-39 kg, 40-54 kg, 55-70 kg, 71-90 kg, and above 90 kg. These bands help in standardizing treatment protocols and ensuring that patients are neither underdosed nor overdosed.

Explanation of Other Options:

Three

Rationale: Having only three weight bands would not provide sufficient granularity to tailor the TB treatment effectively for all adults. It could lead to either underdosing or overdosing in many cases, impacting the efficacy and safety of the treatment.

Four

Rationale: While four weight bands would offer more granularity than three, it is still not as precise as five bands. The additional division provided by five weight bands helps in more accurately tailoring the medication dosages to a wider range of body weights.

Six

Rationale: Having six weight bands might offer even more granularity, but it could complicate the treatment protocols unnecessarily. The five established weight bands are considered sufficient for effective TB treatment in adults.

Conclusion:

The correct number of adult weight band categories for the treatment of TB is five. This number provides an optimal balance between precision in dosing and ease of treatment administration, ensuring effective and safe treatment for a broad range of adult patients.
