22
Q

Agonists=

A

sympathomimetics

23
Q

Isoproterenol (Isuprel) action

A

bronchodilator

24
Q

Albuterol

A

Bronchodilator

25
Q

the agent used to treat extravasation of dobutamine.

A

Phentolamine

26
Q

For a client in shock, dopamine helps to:

A

increase blood pressure

27
Q

Which would the nurse identify as a naturally occurring catecholamine?

A

Dopamine

28
Q

Constricts Pupils= miosis (small word=small pupil)
Contraction smooth muscle GI=peristalsis
Vasodilation
Bronchoconstriction
Increased secretions bronchus
Slows heart rate
Decreased myocardial contractility

A

Effects of the Parasympathetic Nervous System

29
Q

Breakdown of glucose by enzymes, releasing energy

A

Glycolysis

30
Q

Breakdown of glycogen into glucose

A

Glycogenolysis

31
Q

In the sympathetic response, corticosteroids reduces inflammation and also

A

releases glucose into the bloodstream

32
Q

Mydriasis

A

Pupil dilation

33
Q

Pallor is what type of response?

A

Sympathetic

34
Q

Example of catecholamine drug

A

epinephrine

35
Q

Example of non-catecholamine drug

A

albuterol

36
Q

drugs that cannot pass blood brain barrier

A

catecholamine

37
Q

drugs that can pass blood brain barrier

A

non-catecholamine

38
Q

Drug used to treat: acute cardiac arrest, respiratory, and allergic disorder hypotension

A

epinephrine

39
Q

Contraindications for adrenergic drugs

A

avoid adrenaline

40
Q

Drugs that promote

A

agonist

41
Q

Drugs that prevent

A

antagonist

42
Q

Example of adrenergic agonist

A

bronchodilator ie albuterol

43
Q

example of adrenergic antagonist

A

beta blockers

44
Q

beta blockers cause the heart rate to

A

remain low, blocking adrenergic response

45
Q

beta blockers cause lower HR during exercise so the patient gets

A

tired faster because of low O2

46
Q

Major alpha and beta adrenergic blocking agent side effect

A

Hypoglycemia

47
Q

why should the nurse be cautious with diabetic patients taking Beta Blockers?

A

Beta blockers cause heart rate to decrease and in diabetic patients if there is decrease in the sugar levels then patients would have increase in the heart rate as a warning sign, if the person is on beta blockers it would mask the warning sign which can be fatal and so it is not contraindicated but should be cautiously given in a known case of diabetes.

48
Q

SLUDGE

A

Salivation
Lacrimation
Urinary Incontinence
Diarrhea
GI Cramps
Emesis

49
Q

Example of an anticholinergic drug for n/v

A

scopolamine

50
Q

anticholinergic for overactive bladder

A

oxybutin

51
Q

Anticholinergic drug that decreases secretions

A

Atropine
