NUSA 207 Exam 4 With
Complete Solution
Alpha 1 causes - ANSWER - vasoconstriction
- increased peripheral resistance
- increased blood pressure
- mydriasis (pupil dilation)
- increase closure of bladder internal sphincter
Beta 1 causes - ANSWER - tachycardia
- increased lipolysis
- increased myocardial contractility
- increased release of renin (leading to increased BP)
Beta 2 causes - ANSWER - vasodilation
- bronchodilation
- increased release of glucagon
- relaxation of uterine smooth muscle
,Beta 1 blockers affect - ANSWER heart
Beta 2 blockers affect - ANSWER lungs
Primary BP factors - ANSWER - blood volume
- peripheral resistance
- cardiac output
Blood volume - ANSWER fluid loss
- dehydration
fluid retention
- aldosterone
- ADH
Peripheral resistance (diameter of arterioles) - ANSWER - sympathetic
nervous system activity
- renin/angiotensin II
- increase in blood viscosity
Cardiac output - ANSWER stroke volume
, - preload
- contractility
- afterload
heart rate
- sympathetic nervous system
- parasympathetic nervous system
- epinephrine
Primary hypertension - ANSWER - no identifiable cause
- essential hypertension
Secondary hypertension - ANSWER - specific cause of the HTN can be
identified
- Cushing's syndrome, hyperthyroidism, renal disease
Chronic hypertension - ANSWER - causes the heart to work harder to pump
blood to organs and tissues
- can lead to kidney damage, stroke, heart attack
Angiotensin-converting enzyme (ACE) inhibitor - ANSWER captopril
