How should the nurse best respond to the patient's question? A) "Multiple drugs are used because doctors aren't sure which drug will kill a particular TB strain."
B) "The use of multiple drugs prevents the development of drug-resistant TB."
C) "Multiple drugs are prescribed because the final testing results for TB can take up to 3 months."
D) "Multiple drugs are used in order to speed up the course of treatment."

Use of multiple drugs to treat TB is necessary to prevent the development of drug-resistant TB. This approach to treatment is not necessitated by delays in testing, questionable diagnostic results, or the need to hasten the course of treatment.
