IV therapy clinical UPDATED ACTUAL
Exam Questions and CORRECT
Answers
The drip chamber of the administration set should be filled with fluid to which of the listed
capacities? - CORRECT ANSWER - 1/3-1/2
What is the appropriate height for suspending the fluid container from the IV pole in relationship
to the intended IV site? - CORRECT ANSWER - 3 feet
What veins are used for peripheral IV insertion? - CORRECT ANSWER - Forearms
hands
scalp
feet - need dr order- high risk for clot in adults ,PEDS is okay
-midline catheter -peripherally inserted venous access device
PICC line - CORRECT ANSWER - Peripherally Inserted Central Catheter
Central venous catheter - CORRECT ANSWER - a catheter that is advanced through the
internal jugular vein, cephalic or basilic vein in the antecubital fossa, or subclavian vein, with the
catheter tip terminating in the superior vena cava
may also be inserted into a femoral vein with catheter tip then terminating in the inferior vena
cava
may be used to administer prescribed IV infusion tx or to perform prescribed IV infusion
diagnostic procedures
Unlike peripheral intravenous catheters typically inserted into the veins of the hand or forearm, -
CORRECT ANSWER - central access devices are inserted into large veins in the central
,circulation. The tip of a central venous catheter is generally threaded into the internal or external
jugular veins or into the lower third of the vena cava (superior or inferior) that leads to an area
just above the right atrium. At the time of insertion, a chest x-ray is done to confirm proper tip
location and catheter position and to make sure that there is no pneumothorax
a central line - CORRECT ANSWER - depending on the type, can remain in place for
more than a year. Central lines are especially beneficial for patients who have chronic diseases
and require long-term intravenous therapy.
A central line is indicated for patients who need: - CORRECT ANSWER - parenteral
nutrition
chemotherapy or other vesicant or irritating solutions
blood products
antibiotics
IV medications or solutions (when peripheral access is limited)
central venous pressure monitoring
Four types of central venous access catheters are available - CORRECT ANSWER -
nontunneled
tunneled
implanted port
peripherally inserted central catheter (PICC)
CENTRAL LINE ---Flushing with preservative-free, sterile 0.9% sodium chloride solution -
CORRECT ANSWER - helps ensure and maintain patency of all types of central venous
access devices. Your facility's policies will specify flushing procedures to perform after catheter
placement, before fluid infusion, and before and after blood sampling and drug, blood-product,
and parenteral nutrition infusions.
When flushing a central venous access device catheter, use a pulsing (push - stop - push - stop)
flush to create turbulence that helps clear blood and medications from the line. Use a volume of
flush solution that is at least twice the volume capacity of the catheter and add-on devices. (On
average, a tunneled catheter has an internal volume of 1.5 to 2 mL, while a PICC holds 0.5 to 1
,mL.) If you meet resistance or cannot aspirate blood, take further steps to assess the catheter's
patency before you administer medications and solutions. Do not flush the catheter forcefully.
Heparin flushing. Most central venous access devices require heparin flushing. - CORRECT
ANSWER - Flushing with heparin helps ensure and maintain patency of the central venous
access device. Heparin is available in several concentrations. Check your facility's policies to
determine the concentration and volume of heparin required for the specific device as well as the
frequency of the flush. The goal is not systemic anticoagulation; it is catheter patency.
LPN cannot remove a - CORRECT ANSWER - central line
IV bolus or push drug administeration - CORRECT ANSWER - the administration of
medication rapidly into the vein, to enter the blood stream in a short period of time, and to
provide a specific systemic effect
premixed drugs for IV administration - CORRECT ANSWER - those drugs compounded
or prepared by the pharmacy dept, parenteral fluid or drug manufacturer, or mixed by a RN who
possesses documented evidence of the necessary cognitive and psychomotor instruction by a
licensed pharmacist
Microdrip tubing delivers a drop factor of: ______ - CORRECT ANSWER - tubing is
narrower and so produces smaller drops. It is used for children and infants, elderly because of
higher risk for fluid overload.
- Or to infuse sensitive medications where precision in the flow rate is essential.
Microdrip tubing (sometimes called minidrip) comes in only one size
60 gtt/1mL
-allows controlled delivery of small vol of fluid.
-metal mini-tip drop orifice
-forms very small drops
-delivers 60gtt/ml
, Macrodrip primary standard set - CORRECT ANSWER - 10 gtt/cc
15 gtt/cc
20 gtt/cc
tubing is wider and so produces larger drops. It is the tubing most commonly used for routine IV
administration, such as infusion of IV fluids that do not contain sensitive medication.
what factors should the nurse consider when selecting IV cannula gauge? - CORRECT
ANSWER - Blood & Blood products- IV gauge must be no smaller than 20G
acceptable gauges -- 20G , 18G, 16 G, or larger.
venous access devices for peripheral IV insertion include
-ONC
-steel needle devices
-winged or butterfly devices
the only fluid that is compatible with blood is - CORRECT ANSWER - NS
- can flush with NS.
blood is administered with a - CORRECT ANSWER - filter
filtering out any clots, debris,
-anticoagulant inside blood by blood bank
Y tubing - CORRECT ANSWER - never has an injecting port
-don't try to find a way to inject
- 4 hours
-can give rapidly -nurse determines how fast to administer blood. Dr don't give specific
directions
