Hypertension causes resistance in your blood vessels, or afterload; your heart works harder, and weakens. This can lead to heart failure.
Step-by-step explanation:
The best response by the nurse is option 1: "Hypertension causes resistance in your blood vessels, or afterload; your heart works harder, and weakens."

This prolonged strain on the heart can lead to heart failure, where the heart becomes unable to pump blood effectively to the vital organs.
