Answer to Question 1

ANS: 3

Answer to Question 2

3. Ineffective Therapeutic Regimen Management

Rationale:
The treatment regimen for tuberculosis requires that the client take many medications, maintain nutrition, and be aware of potential side effects. Due to increased age and normal forgetfulness, this client is at risk for ineffective treatment in the home. The client is at risk for injury because of age, not TB. The client may have anxiety but the priority is the treatment regimen. Since the client is being treated in the home, there is not much risk for ineffective breathing.
