Causes of inaccuracy in arterial line readings: -ANSWER ->Air
bubbles in the catheter system
Failure to zero the transducer air-fluid interface
Blood in the catheter system
Blood clot at the catheter tip
Kinking of the tubing system
Catheter tip lodging against the arterial wall
Soft, compliant tubing
Long tubing
Too many stopcocks (>3)
What is the pathology of afterload? -ANSWER ->The pressure in
which the heart must pump against in order to eject blood
during systole.
Medications that reduce afterload/preload include? -ANSWER -
>Vasodilators
Indication for arterial line placement? -ANSWER -
>Hemodynamic monitoring
Multiple blood samples
Diagnostic or interventional radiology procedures
Continuous cardiac output monitoring
,What test must be preformed prior to an arterial line
placement? -ANSWER ->Allen's test
How often should a fast flush test be preformed? -ANSWER -
>Every 8 hours
After blood draws
If the hemodynamic status changes
When changing tubing
What are the most common sites for arterial line insertion? -
ANSWER ->Radial
Femoral
Axillary
Dorsalis Pedis
Brachial Arteries
Positioning for radial arterial line placement: -ANSWER ->30-60
degrees of dorsiflexion with the aid of a roll of gauze and an
armband.
Avoid hyperabduction of the thumb.
How often should the atrial line catheter be changed out? -
ANSWER ->Every 7 days
What is the pathology of preload? -ANSWER ->The filling
pressure of the heart at end of diastole.
,What is systemic vascular resistance (SVR)? -ANSWER -
>Resistance the left ventricle must overcome to open the aortic
valve and eject a volume of blood into systemic circulation.
Systemic vascular resistance (SVR) is used for what
calculations? -ANSWER ->Blood pressure
Blood flow
Cardiac function
What is pulmonary vascular resistance (PVR)? -ANSWER -
>Resistacne the right ventricle must overcome to open the
pulmonic valve and eject a volume of blood in the pulmonary
vasculature.
What is pulmonarartery occlusion pressure (PAOP)? -ANSWER -
>The pressure created by the volume of blood that remains in
the left heart at end-diastole.
Inotropic drugs mode of action: -ANSWER ->Negative inotropic
drugs weaken the force of muscular contractions.
Positive inotropic drugs increase the strength of muscular
contractions.
Inotropic drug examples: -ANSWER ->Dobutamine
Digoxin
Milrinone
Dopamine
, Vasodilator mode of actions: -ANSWER ->Relaxes the smooth
muscles of the blood vessels opening them up.
Vasodilator drug examples: -ANSWER ->CCBS:
Verapamil (Calan, Isoptin)
Diltiazem (Cardizem)
Atorvastatin (Lipitor)
Nitrates:
Sildenafil (Viagra)
Nitroprusside (Nipride, Nitropress)
ACE:
Captopril (Capoten)
Lisinopril (Prinivil, Zestril)
Kayexalate -ANSWER ->Exchanges K+ ions for Na+
Excess K+ ions are fecally excreted
Calcium Gluconate -ANSWER ->Prevents and treats cardiac
toxicity related to increased K+ levels
What is the purpose of Continuous Renal Replacement Therapy
(CRRT)? -ANSWER ->Dialysis
This is a blood filtering therapy that replaced the normal blood-
filtering function of the kidneys in patients with renal failure
and acute kidney injuries.
The prerenal system -ANSWER ->Delivers blood to the kidneys.
