HESI PHARMACOLOGY PRACTICE 3 EXAM

HESI PHARMACOLOGY PRACTICE 3 EXAM A client with HIV who was recently diagnosed with tuberculosis (TB) asks the nurse, "Why do I need to take all of these medications for TB?" What information should the nurse provide? A. Antiretroviral medications decrease the efficacy of the TB drugs. B. Multiple drugs prevent the development of resistant organisms. C. Duration of the medication regimen is shortened. D. Potential adverse drug reactions are minimized. B. Multiple drugs prevent the development of resistant organisms. Rationale: A multidrug regimen is prescribed for a client with HIV and TB to prevent the development of resistance of the tubercle bacilli (B). Although antitubercular medications can inhibit some antiretrovirals (A), a multidrug regimen is needed to inhibit the proliferation of the virulent tubercle bacilli. The duration of antitubercular therapy is typically 6 to 9 months and is not shortened (C) by the use of multiple medications. A client who is receiving HIV and TB therapy is at an increased risk of adverse reactions (D) because of the complex medication regimens and complications secondary to immunosuppression.
