Final answer:
The nurse can best promote the client's adherence to the prescribed therapeutic regimen by having the client participate in monitoring their own blood pressure and encouraging weight loss and regular exercise.
Step-by-step explanation:
The nurse can best promote the client's adherence to the prescribed therapeutic regimen by having the client participate in monitoring his or her own blood pressure (option b). This allows the client to take an active role in managing their condition and helps them understand the impact of their lifestyle choices on their blood pressure levels. By regularly monitoring their blood pressure, the client can track their progress and make necessary adjustments to their medication or lifestyle as needed.
In addition to self-monitoring, encouraging the client to lose weight and exercise regularly (option d) is also important for managing hypertension. This can help reduce blood pressure levels and improve overall cardiovascular health.
