Which information is most important for the nurse to include when teaching a client newly diagnosed with hypertension?

Among the given options, the most important information for the nurse to include when teaching a  client newly diagnosed with hypertension is option C, "Increasing physical activity controls blood  pressure (BP) for most people." 

Option C emphasizes the importance of increasing physical activity as a primary lifestyle modification  to control blood pressure for most people with hypertension. Regular physical activity can help  improve cardiovascular health, reduce blood pressure, and manage overall health. It is a proactive  step that the individual can take immediately to start managing their hypertension. 

Incorrect: 

Option A, "Most people are able to control BP through dietary changes," is not necessarily true for  everyone. While dietary changes, such as reducing sodium intake and adopting a heart-healthy diet,  can be beneficial in managing hypertension, they may not be sufficient for everyone. Physical activity  is an essential component of hypertension management and has broader health benefits. 

Option B, "Annual BP checks are needed to monitor treatment effectiveness," is important  information, but it is more of a recommendation for ongoing hypertension management rather than  the most critical information for someone newly diagnosed with hypertension. Regular blood  pressure monitoring is indeed crucial for treatment assessment and ensuring that the chosen  treatment plan is effective. 

Option D, "Hypertension is usually asymptomatic until target organ damage occurs," is important  information to understand the nature of hypertension, but it does not provide immediate guidance  for the newly diagnosed individual on how to manage their condition effectively. 

As part of a comprehensive hypertension education plan, the nurse can provide additional  information about dietary changes, regular blood pressure monitoring, and the importance of early  management to prevent target organ damage. However, emphasizing physical activity as a  fundamental aspect of hypertension management is the most important initial step for a newly diagnosed client. The nurse can then tailor the education based on the individual's specific needs  and health status.
