PN PHARMACOLOGY ATI PROCTORED EXAM WITH ALL 60 NGN QUESTIONS AND ANSWERS & RATIONALES GUARANTEED PASSReceptors - ANSWER>>>Norepinephrine-Adrenergic (adrenergic comes from the word adrenalin) Alpha 1-all sympathetic target organs except the heart-constrict the blood vessels and dilation of pupilsAlpha 2-Presynaptic adrenergic nerve terminal-inhibits the release of norepinephrine Beta 1-Heart and Kidneys (BETA 1-ONE HEART)-increased heart rate and force of contraction, release of renin Beta 2-All sympathetic target organs-inhibits smooth muscle (BETA 2-TWO LUNGS) Beta blockers/olol's - ANSWER>>>Beta-Adrenergic Blockers Metoprolol/Lopressor ENDING OLOL Beta Blockers are use with heart failure, hypertension, angina and with myocardial infarctions. Action = Blocks Beta-Receptors in the heart causing... Decreases = HR, force of contraction, Rate of atrioventricular (AV) conduction SE = Bradycardia, lethargy, GI disturbance, congestive heart failure, decrease BP, depression The beta blockers stop sympathetic nervous system stimulation of the heart. Does not allow the heart rate and blood pressure to rise with stress thus lowering the oxygen demand of the heart. It is very heart protective! Will slow the heart rate and lower the blood pressure Can have beta 2 blockage with larger doses-will constrict the bronchioles-watch for clients with known COPD, AsthmaNursing Interventions Check pulse-needs to be 60 or above Check blood pressure-if
