Galen Pharmacology Exam 2 Latest Update Graded A+ Adrenergic Agonist epinephrine: activates the SNS by increasing BP (alpha1), HR (beta1) and promotes bronchioldilation (beta2) SNS response from adrenergic agonists agents that activate adrenergic receptors in the sympathetic nervous system causing o Dilates pupils, increases intraocular pressure o Dilates bronchioles o Increases heart rate and strength of contractions o Constricts blood vessels and increases BP o Reduces GI secretions...

ersantine Chemical Stress Test - Answer -aka dipyridamole -anti-platelet agent that dilates the coronary blood vessels -side effects: abd upset, arrhythmias, dizziness, headache, CP, low BP, rarely a heart attack or stroke -aminophylline reverses the side effects Negative Stress Test - Answer -no abnormalities seen in the J-point or ST segment -pt achieves at least 85% of max HR -pt's have a low likelihood of developing CV disease or experiencing myocardial ischemia
