The nursing care plan addresses a patient complaining of dizziness. It assesses the patient's risk for hypertension due to lack of disease knowledge. The diagnosis is risk for hypertension. The plan includes defining hypertension and its treatment regimen to the patient, identifying modifiable risk factors like diet and stress, and suggesting lifestyle changes to control blood pressure such as rest, exercise, and limiting sodium and caffeine. The rationale is to educate the patient and decrease risk of end-organ damage from long-term high blood pressure. The evaluation will assess the patient's understanding after interventions.
