Flashcards in Tidbits for midterm Deck (24):
1

Fight or flight (adrenergic) response includes what?

pupil dilation
inhibition of saliva
accelerated HR
bronchialdilation
inhibition of peristalsis
conversion of glycogen to glucose
secretion of adrenaline
inhibition of bladder contraction (can't pee)

2

Acetylcholine is synthesized from _______ and released at the end of all presynaptic ganglia and the _______ nerves in the psns

choline; postganglionic

axon terminal

3

______ is drooping of the eyelid

ptosis

4

Adrenergic blockers are used to....

decrease HR
decrease BP

5

What is the difference between indirect and direct acting?

binds DIRECTLY to receptors

or INDIRECTLY blocks acetylcholinesterase so it cannot kill the ACh

6

urecholine lets the water out! So what can it be used to treat?

dry mouth, glaucoma and increase urination.

7

Uncle Ari (Aricept) and Uncle Don (Donzepil) have what disease?

alzheimers

Donezpril = once a day = one and done

8

Dopamine stimulates the release of NE from the nerve ending increasing cardiac output (CO) and blood pressure. What can it treat?

hypotensive shock

9

A person is in shock, has cardiac standstill, or heart block after a transplanted heart. We need a beta agonist. Which one is best to use?

isoproterenol (isuprel)

10

Why do you have to taper off of beta blockers?

rebound hypertension

11

Adrenergic blockers can hide the symptoms of ______

hypoglycemia

12

Phentolamine diagnosis phe....

pheochromocytoma - tumor in medulla adrenal gland

13

Phentolamine - Regitine causes vasodilation so it must be a _____ blockers.

Alpha blocker

PHentoLAmine
PHLA = ALPHA

14

Name the catecholamines....

dopamine, epinephrine, norepinephrine

15

______ decreases vascular tone and causes vasodilation. It also block smooth muscle receptors in prostate which relaxes the prostate for improved flow. So it is great for treating BPH!

doxazosin (cardura)

fall in blood pressure
block smooth muscle receptors in prostate which relaxesthe prostate for improved flow.

16

This drug is a PRO at preventing reinfarction after myocardial infarction (effects heart hint hint). The danger is giving it to diabetic patients because it is a PRO at hiding hypoglycemi signs.

PROpranolol (Inderal)

17

Atenolol (Tenormin) tends to be given to smokers because it doesn't effect the _____ ____ receptor.

It does tend to interact with NSAIDs

beta 2.

Ten Ten Tends...

18

What is miosis?

What is mydriasis?

mi·o·sis
mīˈōsəs/Submit
noun
excessive constriction of the pupil of the eye.



mydriasis - excessive pupil dilation

19

BethaneCHOL and UreCHOLine are cholinergic agonists that ____ tone of the detrusor and bladder and ___ the bladder sphincter to improve bladder function.

increase tone

relax sphincter

Since we are promoting peeing, an adverse effect? Going to far and creating urinary urgency

20

Mestinon treats M____ ____

myasthenia gravis

Pyridostigmine (STIgM = STIM = stimulate muscles again)

21

Tensilon, Enlon is a diagnostic agent for?

myasthenia gravis

ENLOn = ENd before LONg

This drug only last for a short time and then the person returns to weak muscles

22

Why do anticholinergics create dry mouth?

against psns - against rest and digest - puts you in SNS where you have no saliva and no urination etc

23

This drug is used preoperatively to dry secretions (against PSNS = anticholinergic). It can also be used to also used to restore cardiac rate and BP.

atropine

(memorization: atr - atrialfibrlation - aed - regular cardiac rate)

can cause palpitations and tachcardia if we over correct.

24

Pregnancy classes range from A that is safe and X to not safe. Describe each


Pregnancy
• Class A – HUMAN adequate studies of woman that says okay
• Class B – ANIMAL animal studies okay, but not enough human study
• Class C – ANIMAL show adverse, but not not enough human study
• Class D – DEFINITELY human fetal risk
• Class X – X or cross it off your list, does damage
