NSG 511 Exam 1Sympathetic nervous system - answer Form of autonomic nervous system (involuntary)
Fight & flight response
Beta 1 and 2, and alpha 1 and 2 receptors "adrenergic"
Neurotransmitters = Norepinephrine, Epinephrine, dopamine
Parasympathetic nervous system - answer Form of autonomic nervous system
(involuntary)
Responsible for rest & digestion & secretion
"Cholinergic and muscarinic" receptors Neurotransmitter: acetylcholine
Agonist - answerDrug that activates a receptor
Antagonist - answerDrug that turns off or blocks a receptor
Albuterol (Proventil) - answerSelective beta 2 agonist - effects sympathetic nervous
system
Commonly used for patients with asthma
Beta 2 receptors - answerLocated in the arterioles of heart, lung, and skeletal muscles;
lungs; liver; and uterus
Regulate sympathetic nervous system
Beta 1 receptors - answerLocated in heart and kidney
Regulate sympathetic nervous system
Alpha 1 receptors - answerLocated in the eyes; arterioles of heart, lung, and skeletal
muscle
Regulate sympathetic nervous system
Atropine - answerCholinergic drug
Muscarinic antagonist
Turns off parasympathetic nervous system, increases myocardial oxygen demand and
may be used at end of life or before surgery to reduce secretions in throat
Cholinergic drugs - answerEffect parasympathetic nervous system
Atropine is an example
Bethanechol (Urecholine)
Bethanechol (Urecholine) - answerCholinergic drug

Inhibits aldosterone at the late distal tubule resulting in mild sodium and water excretion
and substantial potassium reabsorption
Mannitol - answerNon-reabsorbed "sugar" solute added to filtrate. Water pulled into
tubule by osmotic gradient. Significant diuresis.
Never used in patients with heart failure because vascular osmotic effect precedes renal
diuretic effect
Things to assess before giving diuretic medications - answerBP
Sodium level
Potassium level
Chloride level
Intake and output
Weight changes
Hydrochlorothiazide - answerMain drug to treat HTN
Except for patients with chronic kidney disease
