Group 1 Flashcards
Includes adrenergic agonists, adrenergic blockers (antagonists), cholinergic agonists, anti-cholinergics
Medication Safety
5 rights, complete orders, assessment of effectiveness, drug action
Adrenergic Agonist Names
Sympathetic = Fight or Flight
Epinephrine, Norepinephrine, Vasopressin, Albuterol, Dopamine, Dobutamine
Adrenergic Blockers (Antagonist)
Beta Blockers (-olol)
Inhibits sympathetic -> slows everything
Beta Blocker (-olol) Names
Selective: Metoprolol, Atenolol
Non-selective: Propranolol
Alpha-beta: Carvedilol, Labetalol
Beta Blocker (-olol) Indications
HTN, dysrhythmia, angina, stage fright
Beta Blocker (-olol) Sx/Adverse
Bradycardia, hypotension, bronchoconstriction, fatigue, orthostatic hypotension
Cholinergic Agonist Types
Direct Acting: stimulate release of acetylcholine
Indirect Acting: inhibit acetylcholinesterase
Cholinergic Agonist Example
Bethanechol (Urecholine)
Cholinergic Agonist General Effects
Cholinergic Stimulation (Chill Drug)
GI and Urinary: increase gastric secretions, motility, urinary frequency
Miosis: constriction of pupil, decreased intraocular pressure
Cardiovascular: decreased HR, vasodilation
Lungs: increased secretion and restriction
Skeletal: increased contraction (nicotinic)
Bethanechol (Urecholine) Indications
Tx of post-op and postpartum non-obstructive urinary retention
Bethanechol (Urecholine) Contraindication
GI tract/bladder integrity is questionable or if there is a mechanical obstruction
Bethanechol (Urecholine) Sx/Adverse
Hypotension, tachycardia, HA, seizure, GI upset, asthma attacks
Bethanechol (Urecholine) Drug Interactions
Acetylcholinesterase inhibitors (indirect-acting cholinergic) can enhance the effects
Bethanechol (Urecholine) Nursing Considerations
Atropine is the antidote, change position slowly, monitor vitals, early ambulation and increased fluid intake if not contraindicated
Anti-cholinergic Examples
Atropine, Tolterodine
Anti-cholinergic General Effects
Cardiovascular: increased HR, dysrhythmias
CNS: restlessness, irritability, disorientation, hallucinations, delirium
Eye: dilates pupils, decreased visual accommodation, increased intraocular pressure
GI: decreased salivation, gastric secretions, motility
GU: urinary retention
Glandular: decreased sweating
Respiratory: decreased bronchial secretions
Dry mucous membranes/dryness
Atropine Indications
Bradycardia, decrease secretions peri-op
Atropine Sxs
Dry mouth, tachycardia, urinary retention, constipation
