General
Silent Killer
High Blood Pressure
Complications on the kidneys due to HTN
Chronic kidney disease, Ischemia, and Renal Failure
Cardiac Output
total blood through systemic and pulmonary circulation per min (SV x HR)
Mild: few symptoms, BP >140/90 1+ urine protein
Severe: BP >160/110 3+ urine protein
Eclampsia: Grand mal convulsions
2 Types of Hypertension
Primary: increase in BP without identifiable cause
Secondary: Specific cause that is identifiable and treated
Complications on the brain due to HTN
Cerebrovascular disease, stroke, Atherosclerosis
Systemic Vascular Resistance
Force opposing movement on blood in vessels
Management
Normal, Elevated, High, Hypertension Crisis Ranges
Normal <120 & <80
Elevated 120-129 & < 80
High 130-139 & 80-89
Hypertension Crisis >180 & >120
Complications on the heart due to HTN
Coronary Artery Disease, (L) ventricle hypertrophy
resistance increases
How it occurs
Change in renal labs, sodium retained, normal renal perfusion decreased, increase in edema and BP, placenta hormones
What is the Vascular Endothelium
Cell layer that line blood vessels
Regulate vasodilation and vasoconstriction
Complications of LVH due to HTN
Increase cardiac work load, (L) ventricle gets too big
What is blood pressure
pressure to move blood and oxygenate body
Two type of HTN in Pregnancy
Chronic: BP >140/90 before 20 weeks
Gestational: HTN after 20 weeks, no protein in urine, no preeclampsia
Symptoms of HTN
Complications on the Eyes due to HTN
Retinal Damage, Blood vessel damage, Loss of vision
What happens to resistance when arteries dilate
Resistance decreases
Nursing Interventions
VS & BP check, check temp for infection, fetal HR, output, weight, urine in protein, pulmonary edema, shortness of breath, vaginal bleeding, s/s worsening preeclampsia
