NUR 243 Exam 1 UPDATED ACTUAL Questions and CORRECT
Answers
what does the PNS regulate? involuntary bodily function (HR, breathing, BP)
what are the three neurotransmitters in PNS? epi, norepi, ach
sympathetic nervous system increase HR, dilate pupils, decrease saliva, dilate bronchi, glucose release, inhibit
urine, decrease pancreatic secrete
parasympathetic nervous system calm body, digestion, slow HR
Muscarinic Agonists - activates activity of ach receptor
- Produce effects through direct interaction with muscarinic receptors
- Parasympathomimetic agents
CHOLINERGIC DRUGS - Agents that influence the activity of cholinergic receptors
- most mimic or block the actions of ach
Muscarinic Agonists effects on heart bradycardia
Muscarinic Agonists effects on exocrine glands increased sweating,salivation, bronchial/gastric acid secretion
Muscarinic Agonists effects on smooth muscle - Contraction in lung (constriction)
• Gastrointestinal tract (increasedtone/motility)
• Bladder (contraction of detrusor)
• Vascular (relaxation, vasodilation, andhypotension)
• Eye (pupillary constriction and ciliarycontraction)
BETHANECHOL [URECHOLINE,DUVOID] Selective agonist at muscarinic cholinergic receptors
effects of BETHANECHOL on heart bradycardia
effects of BETHANECHOL on smooth muscle - Lung: Constriction of the bronchi
• Gastrointestinal system: Increased toneand motility
• Bladder: Contraction of detrusor muscleand relaxation of the trigone
andsphincter
effects of BETHANECHOL on exocrine glands Increased sweating,salivation, bronchial secretions, and secretionof gastric acid
effects of BETHANECHOL on eye miosis and contraction of cililary muscle
thereupetic uses of BETHANECHOL Urinary retention and off-label uses (used for ppl with leaking in their bladder)
, adverse effects of BETHANECHOL Hypotension
Increased tone and motility
Risk of bladder rupture
Exacerbation of asthma
Dysrhythmias in patientswith hyperthyroidism
OTHER MUSCARINIC AGONISTS Cevimeline
Pilocarpine
Acetylcholine
Cevimeline Derivative of acetylcholine which is used to treat dry mouth
Pilocarpine used mainly for topical therapy of glaucoma, decreased intraocular pressure,
used to treat DRY MOUTH
Acetylcholine Used for rapid miosis (pupil constriction) after delivery in cataract surgery
