ANS Prototypes Flashcards
Atropine Drug classes
Therapeutic class: anti-arrythmic, bronchodialtor
Pharmacologic: anticholinegic (antimuscarinic)
Atropine MOA
inhibits the effects of parasympathetic nervous system (increased heartrate, bronchodialation, decreased GU motility)
Atropine uses:
preoperatively decrease GI and respiratory secretions, used for Asthma and COPD (bronchidialation), bradycardia
Atropine nursing considerations
avoid in acute hemorrhage and glaucoma, monitor for tachycardia, may cause urinary retention in elders, may cause constipation
Atropine side effects:
all from too much inhibition of Ach, and too much sympathetic effects
bethanechol (Urecholine) drug classes:
therapeutic class: treatment of urinary retention
pharmacologic class: cholinergic, parasympathomimetic
bethanechol MOA
directly stimulates muscarinic receptors; increasing the tone of the smooth muscle in the bladder; gives a contraction to empty the bladder
bethanechol uses
post operative urinary retention, neurogenic bladder (spinal cord injury or shock)
bethanechol nursing considerations
don’t give to someone with obstructive GI or bladder issue
bethanechol adverse effects
increased salivation, sweating, abdominal cramping and hypotension (fainting)
bethanechol contraindication
don’t give to pts w asthma, epilepsy, parkinsons, peptic ulcer disease, bradycardia
phenylephrine drug classes
therapeutic class: nasal decongestant, antihypotensive, pharmacologic class: adrenergic drug (sympathomimmetic)
phenylephrine action
selective, alpha-adrenergic agonist
phenylephrine intranasal therapeutic effect
reduces nasal congestion by constricting small blood vessels in nasal mucosa
phenylephrine intranasal contraindications
do not use for more than 5 days due to rebound congestion
