– VERIFIED QUESTIONS WITH COMPLETE
CORRECT ANSWERS AND STUDY NOTES.
◎ Before equipment setup and venipuncture, _________ seconds of hand washing
with an antimicrobial soap are recommended. ANSWER:- 15 to 30
◎ What are the advantages to Over-the-Needle catheters? ANSWER:- - easy to insert
- stays patent longer
- catheter tip tapered to prevent peel-back
- radiopaque feature makes x-ray detection easy
- infiltration rare
- winged cannula easy to tape
- stable: allows for greater patient mobility
◎ What are the disadvantages to over-the-needle catheters? ANSWER:- - depending
on the hub, sometimes difficult to secure with tape
- long inflexible stylet increases risk of accidental puncture; pressure marks from hub
- some catheters drag through the skin on insertion
- increased risk of phlebitis
◎ Which statement is true regarding the insertion of an over the needle catheter?
ANSWER:- remove the tourniquet after advancing the catheter into the vein
◎ When starting an I.V., the nurse remembers that a 14 to 16 gauge over the needle
catheter may be selected for which of the following? ANSWER:- multiple trauma, heart
surgery, and transplantation procedures
◎ When choosing the Metacarpal vein for IV therapy, the nurse should remember
which of the following considerations? ANSWER:- - this is a good site to begin therapy
- this site is usually easily visualized
- this site should be avoided if infusing antibiotics, potassium chloride, or
chemotherapeutic agents
◎ When choosing an IV therapy site always try to: ANSWER:- select a vein that's
straight and will not be disturbed when the patient moves
◎ The nurse should monitor the client receiving infusion therapy at least every:
ANSWER:- 2 hours for adults and one hour for children
◎ IV therapy labels should be on which areas? ANSWER:- catheter site, tubing, and
solution container
, ◎ Which IV fluid type pulls fluid into the veins from the more dilute area in cells and
interstitial space? ANSWER:- hypertonic
◎ A client is scheduled a test that requires an NPO status and has been ordered 5%
Dextrose in water (D5W). The nurse understands which of the following to be the best
rational for this action: ANSWER:- isotonic solutions maintain body fluid balance
◎ A patient is prescribed an IV fluid to replace electrolytes and expand plasma volume.
Which type of fluid will the nurse provide to the patient? ANSWER:- hypertonic solution
◎ Is an isotonic solution good to use? ANSWER:- yes, because they maintain fluid
balance
◎ A patient is prescribed an IV infusion of a hypertonic solution. Which fluid shift should
the nurse expect to occur with this type of infusion? ANSWER:- Fluid moves from the
interstitial space into the venous circulation

solution? ANSWER:- 50% dextrose
