NUR 521 EXAMS 1 SETS ANSWERS AND QUESTIONS
SET A+
✔✔muscarinic antagonist - ✔✔class of drugs that act to block Ach at muscarinic
receptors
- block parasympathetic nervous system
✔✔epinepherine - ✔✔used to delay absorption of local anesthetics and control
superficial bleeding
adrenergic agonist
✔✔Alpha 1 - ✔✔receptor that when activated causes mydriasis
- hemostasis
- nasal decongestion
- adjunct to local anesthesia
- increased BP
✔✔what transmitter activates 4 subtypes of adrenergic receptors producing sympathetic
responses - ✔✔epinepherine
✔✔beta 2 - ✔✔receptor that works in the lungs and uterus
✔✔beta 1 - ✔✔receptor that works in the heart and kidneys
✔✔prazosin - ✔✔adrenergic antagonist
- treats HTN and BPH
- has 1st dose effect, the 1st dose can cause loss of consciousness
- perform CV exam: HR, BP, EKG before prescribing
✔✔adrenergic antagonist - ✔✔class of drugs that causes direct blockage of adrenergic
receptors
✔✔clondidine - ✔✔Centrally acting Alpha 2 agonist
, - reduces sympathetic outflow to blood vessels and the heart causing decreased HR
and vasodilation
- educate pt to take at bedtime (sedation)
- drowsiness my lessen with time
- abruptly stoping causes rebound HTN
- high abuse potential with other drugs bc it increases euphoria
✔✔requip (ropinerole) - ✔✔dopamin agonist
selective for D2 and D3 receptors
treats parkinsons and RLS
✔✔Levidopa (sinemet) - ✔✔Dopaminerigc
✔✔Namenda (memantine) - ✔✔NMDA receptor antagonist
- works to bind glutamate at receptor sites with allows calcium to come into the cells
- treats alzheimers
✔✔Donazepil (Aricept) - ✔✔cholinesterase inhibitor
works to stop Ach form found in the brain
- treats alzheimers
✔✔Cholinergic receptor mediate responses to: - ✔✔acetylcholine
✔✔Nictotinic N (neuronal) - ✔✔Promote ganglionic transmission at all ganglia of
sympathetic and parasympathetic nervous system
Promotes release of of epi from adrenal medulla
✔✔Nicotinic M (muscle) - ✔✔causes contraction of skeletal muscle
✔✔Muscarinic - ✔✔-located in most internal organs
-(cardiac, respiratory, GI & GU)
-Activation by Ach = excited or inhibits
- wide therapeutic response
✔✔What is the function of the Parasympathetic division of the PNS - ✔✔think rest and
digest - cholinergic - muscarinic
decrease HR, increase GI movement, constrict eyes (miosis), stimulate salivation,
constrict bronchioles
✔✔What is the function of the Sympathetic division of the PNS - ✔✔fight or flight
dilates pupils (mydriasis), inhibit salivation, increase HR and contractility, dilate
bronchioles, stop digestion, secrete epi and norepi
✔✔What are the functions of the autonomic nervous system - ✔✔to regulate involuntary
process
