B: Urinary frequency
C: Asthma
D: Myasthenia Gravis
D: Myasthenia Gravis is contraindicated because these patients rely on ACh for muscle strength, benztropine is an antiholinergic
Donepezil is an indirect cholinergic agonist because...
A: It increases the production of Ach
B: Inhibits the enzyme that destroys Ach
C: Only affects the brain tissue
D: Reduces the release of Ach at muscle junctions
B: Donepezil is in the drug class Acetylcholinesterase inhibitors, which indirectly increase Ach
Pyridostigmine therapeutic action is:
A: Reducing muscle tremors
B: Improving memory
C: Reducing autoimmune destruction
D: Improving muscle strength
D: Improving muscle strength by indirectly increasing Ach and muscle contraction

B: False. Levodopa is converted to dopamine, carbidopa is the synergistic drug that helps get levodopa to the brain tissue.
Increased Ach may have which common side effects?
A: Nausea and diarrhea
B: Dry secretions
C: Tachycardia
D: Bronchodilation
A: GI disturbances are common and can be severe, maintain hydration if diarrhea is present
A patient with MG says they want to take the medication as needed due to the side effects, what should the nurse tell them?

Cyclobenzaprine is intended for short term use. How long should patients take the medication?
A: 6 weeks
B: 3 weeks
C: 3 months
D: 3 days
B: 3 weeks, taper to stop
Atenolol is used cautiously with diabetic patients, why is this? (select all that apply)
A: Increases glycogen breakdown
B: Blocks insulin release in the pancreas
C: Can masks symptoms of hypoglycemia
D: Reduces insulin sensitivity
B, C, D: Atenolol blocks beta receptors in the pancreas reducing insulin release, it reduces the heart rate and sympathetic response to hypoglycemia and reduces insulin sensitivity.
Which medical history would be contraindicated for carbidopa/levodopa?
A: Diabetes
B: Hypertension
C: Psychosis
D: Parkinsons
C: Psychosis is contraindicated because it is related to dopamine and the goal is to reduce dopamine not increase.
Donepezil can cause parasympathetic side effects due to vasodilation and decreased heart rate, what is the nurses primary safety concerns?
A: Risk of malnutrition
B: Risk of falls
C: Risk of memory loss
D: Risk of fluid overload
B: Risk for falls, hypotension and bradycardia coupled with a drug that can cause GI upset, in a patient who may be confused is a recipe for high risk for falls.
Pyridostigmine is best taken:
A: With food
B: Without food
B: Without

A: Carbohydrates
B: Glucose

A: Reducing heart rate
B: Increasing heart rate
C: Reducing eye pressure
D: Drying secretions
B, D: Atropine is used for symptomatic bradycardia, dilating pupils in eye drop form for an eye exam and drying oral, GI and respiratory secretions prior to surgery or at end of life.
