Blood pressure is the pressure exerted by the blood in circulation against the wall of the blood vessels. It is mostly due to the pressure that is formed during the pumping of blood by the heart. For study and medical purposes, the blood pressure is expressed as a systolic pressure(maximum pressure produced during one heartbeat) over diastolic pressure(the pressure that is produced between 2 consecutive heartbeats). Normal blood pressure ranges around 120/80 mmHg. Mean arterial pressure/MAP is nothing but the average blood pressure produced during the single cardiac cycle. MAP has to be regulated to maintain the blood perfusion to the vital organs. MAP = Cardiac output × systemic vascular resistance + central venous pressure. In this case, the patient is having blood pressure above the normal range, It is 184/100 mmHg (hypertensive). Both the systolic pressure and diastolic pressure have increased. Increased pressure usually exerts mechanical stress on the arterial wall. Chronic hypertension will lead to increase heart workload and develops atheroma in the arterial walls. Total peripheral resistance/TPR is the resistance that the blood has to overcome to push it through and maintain the flow. In this case, the parasympathetic will stimulate arterioles to decrease TPR (last option is the right answer).
