ACTUAL Exam Questions and
CORRECT Answers
A nurse who has just initiated an IV infusion explains to the patient that complications are
possible and that she will monitor the infusion regularly. The nurse should teach the patient that
which of the following findings is an indication of early infiltration? - CORRECT
ANSWER - cooling
Which of the following is an important nursing action when converting an IV infusion to a saline
lock? - CORRECT ANSWER - Flush the IV catheter to confirm patency.
A nurse has just inserted a peripheral IV catheter for continuous infusion. To secure the catheter,
the nurse should: - CORRECT ANSWER - Leave the connection between the hub and the
tubing uncovered. (possible to replace the tubing without removing the dressing)
A nurse initiating a peripheral IV infusion punctures the skin and selected vein and observes
blood return in the flashback chamber of the IV catheter. Which of the following actions should
the nurse perform next. - CORRECT ANSWER - Lower the catheter until is is almost
flush with the skin. (facilitates full penetration of the wall of the vein)
A nurse is removing an IV catheter from a patient whose IV infusion has been discontinued.
Which of the following actions is appropriate? - CORRECT ANSWER - Pull the catheter
straight back from the insertion site. (make sure to keep the hub parallel to the skin)
A nurse is discontinuing an IV infusion. For which of the following reasons is it important to
verify and document the integrity and condition of the IV catheter? - CORRECT
ANSWER - A broken-off catheter tip indicates the risk for an embolus.
A patient in early stage renal failure is prescribed an infusion of 0.45% sodium chloride. This
type of solution is appropriate because it: - CORRECT ANSWER - Dilutes extracellular
fluid and rehydrates the cells. (infusing a hypotonic solution moves fluid into the cells)
,A nurse has just initiated a new peripheral IV infusion with 5% dextrose in water for continuous
infusion. How often should the nurse plan to replace the primary infusion tubing? - CORRECT
ANSWER - every 96 hours
A nurse finds a patient's IV insertion site red, warm, and slightly edematous. Which of the
following actions should the nurse perform first? - CORRECT ANSWER - discontinue the
IV line

division into two branches; fork - CORRECT ANSWER - bifurcation
a small, winged-tip needle used to initiate intravenous access - CORRECT ANSWER -
butterfly needle
a tube inserted into a vessel, duct, or cavity - CORRECT ANSWER - cannula
the "handle" of an intravenous catheter, the part that allows access to the catheter's lumen for a
variety of functions, such as the injection or infusion of fluids or drugs or the introduction of a
guide wire - CORRECT ANSWER - catheter hub
implantation and growth of a micro-organism on or in a host - CORRECT ANSWER -
colonization
a blood-vessel access device usually inserted into the subclavian or jugular vein with the distal
tip resting in the superior vena cava just above the right atrium; used for long-term intravenous
therapy or parenteral nutrition - CORRECT ANSWER - central venous catheter
the portion of an intravenous administration set that lies just below the tubing insertion spike and
allows visualization of the individual drops of solution being infused; the portion squeezed and
, released to begin the flow of solution immediately after insertion of the spike into the solution
bag or bottle when preparing an intravenous infusion set - CORRECT ANSWER - drip
chamber
the calibration or number of drops per milliliter of solution delivered for a particular drip
chamber - CORRECT ANSWER - drip factor or drop factor
a blood clot or a bolus of air developed in or introduced into a blood vessel that moves from its
place of origin and is capable of obstructing blood circulation - CORRECT ANSWER -
embolus
the portion of an over-the-needle catheter that allows observation of a blood return when the
catheter enters a vein - CORRECT ANSWER - flash chamber
loss of both water and electrolytes from the extracellular fluid; also called hypovolemia -
CORRECT ANSWER - fluid-volume deficit
an intravenous catheter inserted into a vein and left in place for the intermittent administration of
medication through its port or as an open line for emergency situations and intermittently flushed
with a heparin solution to maintain patency - CORRECT ANSWER - heparin lock
referring to a solution that has a higher osmolarity than body fluids have - CORRECT
ANSWER - hypertonic
referring to a solution that has a lower osmolarity than body fluids have - CORRECT
ANSWER - hypotonic
seepage or introduction of fluid, such as intravenous fluid, into the tissues surrounding a blood
vessel; similar to extravasation - CORRECT ANSWER - infiltration
slow, intentional introduction of fluid into a vein - CORRECT ANSWER - infusion
