Flashcards in Chap 20 (exam 2) Deck (16):
1

Atropine

Antidote for overdose of a cholinergic drug

2

Indirect-acting cholinergic drugs

Cholinergic drugs that act by making more acetylecholine (ACh) available at the receptor site, thus allowing ACh to bind to and stimulate the receptor

3

Direct-acting cholinergic drugs

Cholinergic drugs that bind to cholinergic receptors and activate them

4

Muscarinic

Receptors located post synaptically in the effector organs (smooth muscle, cardiac muscle, glands) supplied by the parasympathetic fibers

5

Nicotinic

Receptors located in the ganglia of the parasympathetic nervous system (PSNS) and the sympathetic nervous system (SNS)

6

Rest and Digest

A description of the action of the PSNS

7

Acetylcholine

The neurotransmitter responsible for the transmission of the nerve impulses to the effector cells in the PSNS

8

Cholinesterase

The enzyme responsible for breaking down ACh

9

The desired effects of cholinergic drugs come from stimulation of which receptors?
Cholinergic
Nicotinic
Muscarinic
Ganglionic

Muscarinic

10

The undesirable effects of cholinergic drugs come from stimulation of which receptors?
Cholinergic

13

A 62 year old woman has started taking donepezil (Aricept) for early stage Alzheimer's disease. Her daughter expresses relief that "there is finally a pill to cure Alzheimer's disease." What is the nurse's best response?
"She can expect reversal of symptoms within a few days"
"The dosage will need to be increased if no improvement is noted"
"This drug may help to improve symptoms, but it is not intended as a cure"
"Yes, it has been a great help for many patients"

"This drug may help to improve symptoms, but it is not intended as a cure"

Donepezil (Aricept)
Physostigmine (Antilirium)

Atropine

16
