NR 293 FINAL EXAM EXAM QUESTIONS WITH CORRECT VERIFIED ANSWERS | 100% PASS (A+ CERTIFIED) 1. Adrenergic drugscentrally and peripherally acting adrenergic neuron blockers -centrally acting alpha2 receptor agonists -peripherally acting alpha1 receptor blockers -peripherally acting beta receptor blockers -peripherally acting dual alpha1 and beta receptor blockers 2. centrally acting alpha2 receptor agonistsstimulate alpha2-adrenergic receptors in the brain -decrease sympathetic outflow from CNS -decrease norepinephrine production -stimulate renin activity in the kidneys -decrease blood pressure Ex: clonidine (catapres), methyldopa (aldomet) 3. Clonidine: useful in management of withdrawal symptoms in opioid-dependent person 4. Peripherally acting alpha1 receptor agonists: "azosin" -block alpha1-adrenergic receptors -management of severe HF when used with glycosides and diuretics -some used to relieve symptoms of BPH (flomax) 5. "azosin" adverse effects: hypotension (first dose) syncope diziness 6. beta blockers "olol": Reduce BP by reducing heart rate -cause reduced secretion of renin -long term use causes peripheral vascular resistance -improve survival after MI Ex: nebivolol, propanolol, atenolol 7. Dual action alpha1 and beta receptor blockers: reduce HR (beta1) cause vasodilation (alpha 1) result in decreased BP -Carvediolol, labetalol 8. adrenergic adverse effects: high incidence of orthostatic hypotension bradycardia w/reflex tachycardia sexual dysfunction dry mouth drowsiness, sedation constipation depression edema 9. less common adrenergic adverse effects: headache sleep disturbances nausea rash cardiac disturbances (palpitations) 10. ACE inhibitors "pril": inhibit angiotensin-converting enzyme preventing angiotensin 1 from being converted to angiotensin 2 -decreased systemic vascular resistance (afterload) -vasodilation
