A patient diagnosed with TB is undergoing treatment. The nurse knows that which of the following would be used for household members and other close associates of the client to help prevent the spread of the disease?
- A. Long-term therapy
- B. Prophylactic therapy
- C. DOT therapy
- D. Short-term therapy
Correct Answer: B
Rationale: Prophylactic therapy will prevent or avoid the spreading of TB in household members and other close associates of the diagnosed client. Long-term treatment does not prevent the spreading of TB, though it may eventually cure or reduce the intensity of the disease. Directly observed therapy (DOT) is used to administer drugs two to three times weekly. Using DOT will not prevent the TB from spreading. Usually, short-term therapy is of no value in treating TB. Short-term therapy will also not prevent the disease from spreading.

- A. Initial phase of treatment
