What is the MAP estimated to be when the blood pressure is 130/85 mm Hg?

Hypertension in the elderly is a common finding. This is due to the age-related rise in systolic BP. Among the aging processes, what is a contributor to hypertension?
Baroreceptor sensitivity
Pregnancy induced hypertension is a serious condition affecting between 5% and 10% of pregnant women. The most serious classification of hypertension in pregnancy in preeclampsia-eclampsia. It is a pregnancy specific syndrome that can have both material and fetal manifestations.

A client with malignant hypertension is at risk for a hypertensive crisis, including the cerebral vascular system often causing cerebral edema. As the nurse caring for this patient, what are the sign and symptoms you would assess for?
Headache and confusion
The renin-angiotensin-aldosterone system is a negative feedback system that plays a central role in the BP regulation. How does the end result of this feedback loop regulate BP in the body?
Increases salt and water retention by the kidney
The extended, severe exposure of the walls of the blood vessels to the exaggerated pressures that occur in malignant hypertension causes injuries to the walls of the arterioles. Blood vessels in the renal system are particularly vulnerable to this type of damage. Because hypertension is a chronic disease, and it is associated with autoregulatory changes in the blood flow to major organs, what would be the initial treatment goal for malignant hypertension?
Partial reduction in bp to less critical calues
A 37 y/o woman is admitted to your unit with a differential diagnosis of rule out phochromocytoma. What are the most common symptoms you would expect this patient to exhibit?
Periodic severe headache and marked variability in BP
A 75 yo male presents at the clinic for a routine physical checkup. He is found to be hypertensive. While taking his BP in the sitting, standing, and lying positions, the nurse notes that the brachial artery is pulseless at a high cuff pressure, but she can still feel it. What condition would the nurse suspect?
Pseudohypertension
Although the etiology of essential hypertension is mainly unknown, several risk factors have been identified. These risk factors fall under the categories of constitutional risk factors and lifestyle factors. What are the primary risk factors for essential hypertension?
Race and excessive sodium chloride intake, type 2 diabetes and obesity, family hx and excessive alcohol consumption
In infants and children, secondary hypertension is the most common form of hypertension. What is the most common cause of hypertension in an infant?
