A patient asks the nurse why he doesn’t feel sick even though his TB test is positive. The nurse knows the patient has been diagnosed with LTBI. Which explanation is best to provide the patient? 1. “TB often does not make people feel sick, but it is contagious nevertheless.” 2. “You have latent disease, which just stays in your system but won’t ever make you sick.” 3. “You have TB infection, but not active disease. As long as your immune system stays strong, it can keep the infection from making you sick.” 4. “Even though you do not feel sick, the positive test shows that you have the disease and must be treated.”
