• Why is atropine contraindicated in patients with glaucoma?
increase IOP
What is the action of a cholinergic agonist?

What would indicate the patient is having therapeutic effects related to treatment with pyridostigmine?
· Increase in muscle strength
Why do patients with myasthenia gravis (MG) experience muscle weakness?
· Loss acetylcholine receptors · Antibodies attack this area and cause loss of acetycholine · Develop progressive muscle weakness (respiratory muscles and cause problems with their bleeding) o Serious enough to be put on ventilator
What condition is treated with bethanechol and why?
· Nonobstructive urinary retention · Used in problem with urinary retention · Cannot use in someone with an obstructive process · A patient after surgery (abdominal surgery with urine retention): bladder would not contract after surgery due to anesthesia (urinary retention), so would need to be given meds
What type of medication is used to treat myasthenia gravis and why?
· Parasympathomimetic indirect acting Cholinesterase-inhibitors · *tightly shut eyelid very tight and might pick up where the weakness is because they cannot do this · By increase acetylcholine = increase strength · Antidote: Tensilon test (acetylcholine be there and get better, temporoary does not last very long)
What is a hallmark clinical manifestation of MG?
· Ptosis

What should the nurse include as key points when teaching a patient who is taking oxybutynin?
· Anticholinergic · CNS effects · Not great for glaucoma = make intraocular pressure increase · Constipation = increase fiber and fluids · Dry mouth = don't use alcohol-based rinses (drier), loosengens · Worried about Increase HR and BP, palpitations
Why would oxybutynin be prescribed for a patient with urinary urgency and frequency?
· Antispasmodic · Antagonist · Help relax the bladder · May have taken care of patients that have overactive bladder and have to void all the time, incontinence helps relax the muscles in the bladder and calm it down · Inhibit acetylcholine
How do the the parasympathetic and sympathetic nervous system responses differ?
· Counteract and balance for homeostasis o Sometimes this doesn't happen because 1 may override the other o Different medication effects · PNS = rest and digest, · SNS = increase BP, increase HR, see really well (dilate), bronchi dilate (breathe better)
Discuss differences between direct acting and Indirect acting.
· Direct acting: meds are not effected by the enzyme acetylcholinesterase, bind to R and mimic acetylcholine and not being destroyed by the enzyme · Indirect: inhibits the action of acetocholinesterase enzyme, natural binding of achetycholine, inhibitors
For which conditions is oxybutynin medication contraindicated?
· Glaucoma o Don't want pupils to dilate = increase IOP and detrimental to their glaucoma · Mycinogravis: further block the acetycholine · Don't chew it = cause immediate release and bolus of the medication
What are the high priority assessments/ interventions when administering the medication Bethanechol?

•What should the nurse include when providing education about this type of medication?
•Take it at night •No alc •Move slowly because orthostatic hypotension •Sedative effects wear off as take meds •Anticholinergic effects: fluids fiber, sugar losengens •Cardiac problems = need to be on cardiacmonitor, do gastric lavage for this patient
