NURS 5334 EXAM 2 QUESTIONS AND WELL ELABORATED CORRECT ANSWERS 100% VERIFIED BY EXPERTS AS COMPLETELY CORRECT LATEST UPDATE 2024 [GRADED A+] REAL EXAM 100% What are the basic mechanisms by which neuropharmacologic agents act? Modify disease process, act at axons/synapses, affect synaptic transmission What are the 5 steps in synaptic transmission? Transmitter synthesis, storage, release, receptor binding, termination True or False: Neuropharmacologic drugs have high selectivity. True What type of receptors do neuropharmacologic drugs act through? Alpha and beta receptors What are the normal responses to the activation of alpha and beta receptors? Agonists vs. antagonists What are the 3 functions of the autonomic nervous system? Regulate heart, secretory glands, smooth muscles What are the 7 regulatory functions of the parasympathetic nervous system? Slowing heart rate, increasing gastric secretions, emptying bladder/bowel, focusing eye, constricting pupil, contracting bronchial smooth muscle What are the functions of the sympathetic nervous system? Regulate cardiovascular system, body temperature, fight or flight reaction What is the baroreceptor reflex? Receptors near the heart monitor BP changes and activate the Autonomic NS to restore blood pressure. What happens when BP falls in the baroreceptor reflex? Vasoconstriction and increased cardiac output. What happens when BP rises in the baroreceptor reflex? Vasodilation and reduced cardiac output. Where is acetylcholine employed? Most junctions in the peripheral nervous system. Where is norepinephrine released? Postganglionic neurons. Where is epinephrine released? Adrenal medulla. What are cholinergic receptors mediated by? Acetylcholine. What are the subtypes of cholinergic receptors? Nicotinic and muscarinic. What are adrenergic receptors mediated by? Epinephrine and norepinephrine What are the subtypes of adrenergic receptors? Alphas, Betas, Dopamine What are the functions of each adrenergic subtype? Alpha 1: vasoconstriction, ejaculation, bladder and prostate contraction; Alpha 2: minimal clinical significance; Beta 1: control the heart, increase HR, force of contraction, velocity of conduction, stimulate renin release; Beta 2: bronchial dilation, uterine muscle relaxation, vasodilation, glycogenolysis; Dopamine: dilates renal blood vessels Which receptors can epinephrine activat
