Final Flashcards
When should the sharps box be emptied
•when 2/3 full
Hand washing how long & when should you wash
- 10-15 sec
* before eating
Painful site for IV
•radial wrist
3 main veins frequently used
- cephalic
- basilic
- median cubital
Common site for extravasation
•joint flexion area
The 5 R’s
- right pt
- right amount
- right route
- right time
- right drug
Two most significant blood born pathogens
- HBV
* HIV
Since there is no way you can know if a person is infected you should always use
•universal precautions
BUN/Creatinine
- indicates function of kidneys
- disease/dehydration kidney failure
- diabetic
Creatinine
- 0.6-1.5 normal range
* creatinine tells if kidney is filtering waste
BUN
- Blood Urea Nitrogen
- the amount of nitrogen in the blood that comes from the waste product urea
- normal range 8-25
Anaphylactic
•u have been exposed to the reaction before
Isolations
- contact;MRSA, Hep A, varicella
- droplet; rubella, mumps, flu
- airborne; tb, chickenpox, measles
PPE
- personal protective equipment
- gloves
- mask
- gown
- eyewear
Senators bill 1334
•allows techs to complete the injection of CM which was started by authorizing personnel (does not apply for students)
Side effects vs reactions
- side effect expected outcome
* reaction unexpected outcome
Incase of known allergies
•pre-medicate
High risk pt. To administer contrast
- allergic towards iodine contrast
- diabetes
- asthma
Preparation for possible allergic contrast reaction
- crash cart
- epinephrine
- resuscitation equipment
- oxygen/suction
What type of pt makes venipuncture easy
•a relaxed pt
Senate bill 571
•authorizes techs under supervision can perform venipuncture on a upper extremity to administer contrast with a certificate
Iodine
- water soluble
* used for vessels, arteries, veins, & functions of internal organs
Iodine ionic/non-ionic
Ionic;
•high osmolarity (higher risk of complications)
•less expensive
Non-ionic;
•lower osmolarity (lower risk of complications)
•more expensive
Adverse reaction caused by
- osmolarity in the contrast media
* osmolarity=the number of particles in solution
Drug routes
- Sublingual-under tongue
- Topical-on skin
- Oral
- Parenteral-injection
Contrast injection method
- Drip infusion
- IV push
- Power injector
- Piggy back
California law does not allow techs to perform
•arterial puncture
Anaphylactoid reactions
- uticardia-(Benadryl/IV)
- bronchospasm(epinephrine)
- facial/neck edema(epinephrine)
- itching-(Benadryl/IV)
If pt is going to have reactions to CM it will happen with in ______. If pt is going to have a life threatening reaction it will happen______.
- 1-5min
* immediately
Finger nails no longer then
•1/4”
Anaphylactoid
•first time experiencing reaction
Arteries vs veins
Arteries;
•oxygenated, flows away from the heart
Veins;
•deoxygenated, flows to the heart
Nosocomial
•infection originating from the hospital
GFR
•60 and above
Steps of infection
- encounter
- entry
- spread
- multiplication
- damage
- outcome
Chain of infection
- host
- infectious microorganism
- mode of transportation (vector/formite)
- reservoir
Contrast reaction
- difficult breathing
- feeling itchy
- feeling faint
- feeling nauseous
- arm starts to burn
Max contrast in a 24 hour period adult/ped’s
- adult; 200mL
* ped’s; 2.0mL per kg
Isovue 200 or 300
- not go veins
- intrathecal
- myelography
Barium kVp
90-129
Iodine kVp
- below 90
* 70-80
