Final answer:
The incorrect client statement about hypertension therapy indicates that medication can be stopped once blood pressure is normal, which is unsafe as hypertension often requires long-term treatment.
Step-by-step explanation:
The client statement that indicates a need for further teaching about hypertension therapy is: "When my blood pressure is normal, I will no longer need to take medication." This statement is incorrect because hypertension is often a chronic condition, and discontinuing medication simply because blood pressure has temporarily normalized could lead to a dangerous rebound effect. The other statements show an understanding that managing hypertension is a long-term process influenced by medication, lifestyle changes such as diet and weight loss, and adopting careful habits like getting up slowly to prevent dizziness (a symptom of potential blood pressure changes).
