Interventional procedures

Monitor closely for hemorrhage

32

Used to treat Type 2 diabetes
metformin (Glucophage)
IVP exam

Antidiabetic

33

Prevents and treats nausea & vomiting
Before onset of symptoms
prochlorperazine (Compazine)
ondansetromn (Zofran)

Antiemetic

34

Treat allergic disorders; upper respiratory tract infections & the common cold

Antihistamine

35

2 groups of Antihistamine

Sedating antihistamines
Nonsedating antihistamines

36

Sedating antihistamines

diphenhydramine (Benadryl)

37

Nonsedating antihistamines

loratadine (Claritin)

38

Increase the amount of urine excreted by the kidneys
CHF patients
furosemide (Lasix)

Diuretic

39

Causes blood vessels to constrict
Increasing heart action & BP
norephinephrine (Levophed)

Vasoconstrictor

40

Causes blood vessels to dilate
nitroglycerin

Vasodilator

41

Contrast Media

30% of all imaging examinations involve the use of contrast media in order to visualize a body part or system

42

Contrast media is classified as

Drug

43

Contrast media is absorbed

Into the systemic circulation and may produce a physiologic response

44

3 Routes of administration

IV or intravenous
Oral
Rectal

45

IV contrast administered in a large dose over several minutes

Bolus (use w/CT scan

46

IV contrast administered over an extended period of time

Infusion

47

When an anatomical area is filled or outlined by a Positive contrast media, the area will appear white on the image
All positive contrast media except barium contain iodine

Radiopaque

48

Negative contrast media making the area appear darker on the image
Air or gas

Radiolucent

49

What is the most common type of contrast used to image the GI system

Barium

50

Barium

Does not dissolve; remains suspended in solution
Barium(56) and iodine(53) both contain high atomic numbers

51

Chemical structure is

different for ionic & nonionic contrast
Differs in the number of particles in solution; not the number of iodine compounds

52

The iodine provides

the contrast or density difference between an organ and its surrounding tissue

53

Weight of the ion
Can cause side effects for patients

Osmolality

54

Ionic contrast have a higher

osmolality (hyperosmotic to body fluids)

55

Nonionic contrast has

an osmolality closer to human plasma
Less likely to cause reactions

56

Adverse reactions

Range from mild to severe

57

Vasovagal response

Reaction to the procedure and not the contrast agent; high anxiety

58

Most reactions to IV contrast media occur within

the first five (5) minutes after administration
A delayed reaction is also possible

59

Five rights of drug administration
(Golden rules of drug administration)

Right drug
Right amount
Right patient
Right time
Right route

60

Equipment for Venipuncture

Needle
Tourniquet
Alcohol wipes or antiseptic solution
Tape or tegaderm
Gauze
Contrast
Syringe
Bandaid
