Dry mouth, blurred vision, urinary retention, constipation, psychosis, and tachycardia

Question 4

Who should u not give benztropine to. Why

Answer 4

Elderly they are less tolerant of CNS effects (sedation, confusion and delusions)

Question 5

Answer 5

Dopamine

Acetylcholine

Question 6

What does restoring the dopamine and acetylcholine balance in the brain do

Answer 6

Helps resolve abnormal muscle contractions and results in improved muscle coordination.

Question 7

Anticholinergic side effects

Answer 7

Common bc most muscarinic receptors are nearby parasympathetic nerves

Question 8

Although benztropine is centrally acting, what may it effect also

Answer 8

Peripheral muscarinic receptors

Question 9

The defiency of ___ associated with Parkinson’s disease results in excessive Cholinergic activity

Answer 9

Dopamine

Question 10

How does benztropine (cogentin) treat parkinsons

Answer 10

Decreases acetylcholine effect on the brain and minimizes tremors and stiff muscles associated with Parkinson’s

Question 11

What is acute dystonia

Answer 11

Some antipsychotic medications block dopamine receptors and cause extrapyramidal symptoms, such as involuntary muscle movements or slurred speech

Question 12

How does benztropine treat acute dystonia

Answer 12

Block centrally acting muscarinic receptors and decreases involuntary abnormal muscle contractions associated with antipsychotic medications

Question 13

Side effects of benztropine

Answer 13

Blurry vision, dry mouth, urinaly retention, tachycardia, constipation, psychosis

Question 14

Why does benztropine cause blurred vision

Answer 14

Blocks Cholinergic receptors int he eye and paralyze ciliary muscles, focusing on far objects and causing nearby objects to look blurred

Question 15

If give a patient benztropine what tell patient

Answer 15

Warn f blurred vision, don’t let drive and measure the patients intraocular pressure

What do if give patient benztropine

Answer 17

Give sips of water while encouraging oral hygiene

Question 18

How does benztropine cause urinary retention

Answer 18

Inhibit binding of acetylcholine at muscarinic receptors M2 M3 on detrusor smooth muscle cells . Decreases muscular tone of the bladder wall and causes urinary retention.

Question 19

How minimize urinary retention in benztropine

Answer 19

Advise patient to void immediately prior to taking benztropine

Question 20

If get severe urinary retention. What give patient

Answer 20

Muscarinic agonist (bethanechol) monitor input and output

Question 21

How does benztropine cause tachycardia

Answer 21

Block parasympathetic nerves of the heart and cause cardiac dysrhythmias.

Question 22

Why does benztropine cause constipation

Answer 22

Block muscarinic receptors of the intestinal tract. Decreasing tone and motility of the intestinal smooth muscle and result in constipation.

Question 23

Who is benztropine contradicted in

Answer 23

Patients with low intestinal muscle tone

Advise patient to minimize effects of constipation by increasing fiber

Question 24

What does benztropine cause psychosis

Answer 24

Cause CNS excitation.

-visual hallucinations , vivid dreams, paranoia

What happens if a patient takes benztropine gets psychosis

Answer 25
