Final answer:
The most therapeutic instruction for a client with preeclampsia is to rest in the side-lying position, alongside other measures such as a healthy diet low in sodium and ensuring adequate hydration without overly restricting fluid intake. Exercise should be moderated according to the healthcare provider's advice.
Step-by-step explanation:
The most therapeutic instruction for a client with preeclampsia to improve her health is to rest often in the side-lying position. This position can help improve blood flow to the placenta, which is beneficial for both the mother and the developing fetus. Other important health measures include limiting sodium intake, as a sodium-restricted diet helps to control blood pressure, a significant concern in preeclampsia. Reading food labels and choosing options with lower sodium levels is essential. Additionally, staying hydrated is crucial, and the client should aim to drink enough water to make 2 to 2.5 liters of urine per day. However, they should not limit their fluid intake to only 1000 mL daily as this could lead to dehydration.
Regular, mild exercise such as walking may be beneficial for pregnant women in general, but for someone with preeclampsia, rigorous exercise should be avoided or discussed with a healthcare provider. It is important to note that managing preeclampsia often involves a comprehensive approach, including close monitoring by healthcare professionals, and lifestyle adjustments should be made under their guidance.
