Final answer:
A patient with untreated Stage II HTN faces serious health risks and potential complications including heart disease and stroke, due to blood pressure levels of 140/90 mm Hg or higher.
Step-by-step explanation:
The condition of a patient with Stage II Hypertension (HTN) without a prior diagnosis or without treatment would be considered serious, as it involves chronic and persistent blood pressure measurements of 140/90 mm Hg or above. This stage of hypertension significantly increases the risk for developing serious health complications such as heart attack, stroke, peripheral arterial disease, chronic kidney disease, and heart failure. Called the "silent killer," HTN often does not present with symptoms, making it crucial for individuals to regularly monitor their blood pressure and adhere to a treatment plan if diagnosed. Lifestyle changes combined with medications are important for managing high blood pressure and reducing the risk of cardiovascular diseases.
