Should you shave or clip hair of an IV site before starting an IV?
Ans: Clip! Shaving the hair may cause tiny abrasions which
could increase the risk for infection.
Which anatomical part should be avoided in the elderly when starting
an IV?
Ans: The dorsal part of the hand because the veins are
susceptible to damage and the hand can be bumped easily.
What may be used instead of a tourniquet with the elderly?
Ans: Blood pressure cuff
An adult patient developed a complication with his IV and it had to be
removed, yet continued IV fluids were needed. Which site would be
most appropriate for the nurse to choose?
a. Proximal to the previous IV site.
b. Distal to the previous IV site.
c. In the antecubital fossa.

d. In the foot.
Ans: A (The most appropriate site would be proximal to the
previous site or in the opposite extremity if possible. The foot in
an adult should be avoided. Having the IV catheter located in
the antecubital fossa would limit the patient's movement.)
List the steps taken to inset a peripheral intravenous device.
Ans: 1. Verify order on patient chart, unit standing
orders/protocol. Review facility policy.
2. Assemble equipment including the selection of the
appropriate gauge catheter
3. Provide for privacy. Perform hand hygiene.
4. Introduce self to patient/client. Identify patient/client with 2
identifiers & MRN. Explain purpose and procedure to the
patient/client. Raise bed to a comfortable working height.
5. Organize and prepare equipment including priming the
extension set with saline. Ensure sterility of equipment. Place
nearby in the sterile package.
6. Adhere to principles of asepsis and utilize standard
precautions.
7. Inspect potential insertion sites to select vein. Be aware of
your particular pt. (their age, where they have had previous
successful IV's inserted, cardiovascular diseases or other
complicating diseases that may affect IV insertion).

8. Apply tourniquet 2-6 inches above the selected site to
occlude venous flow. Leave on no more than one minute. May
remove and then reapply after cleansing the insertion site.
Prevent venospasm.
9. Don clean gloves, apply tape to glove for later use, and
cleanse insertion site with antimicrobial barrier according to
manufacturer's guidelines for how to and amount of time to
cleanse. Refrain from touching the cleansed site. Allow to air
dry according to agent used. (A facility may stock 10%
povidone-iodine or 70 % alcohol, or 2% aqueous chlorhexedine
gluconate (Chloraprep), If chlorhexidine cleanse area with
repeated back-and-forth strokes of the applicator for 30 second
and let dry for approximately 2 minutes.) Chlorhexidine reduces
the skin surface bacteria. Allowing it to dry completely
promotes maximum bactericidal effectiveness.
10. Anchor vein by stretching patient's skin distal to the site
with thumb or forefinger far enough away (1 -2 inches) from the
site so that the
At what angle should an IV catheter puncture the skin and vein during
insertion in a middle-aged adult?
a. 10- to 30-degree angle
b. 45-degree angle
c. 90-degree angle

, Page |4
d. 5- to 10-degree angle
Ans: A (The skin and vein should be punctured with the
catheter held at a 10- to 30-degree angle. The angle of insertion
may be decreased when inserting the catheter into an elderly
patient to avoid rolling the vein or puncturing through the vein.
Superficial veins require a smaller angle, and deeper veins
require a greater angle. A 45-degree angle may be used for
administering a subcutaneous injection. A 90-degree angle may
be used to administer an intramuscular injection.)
When should the tourniquet be released a second time during the
procedure for insertion of a peripheral intravenous device?
a. After the catheter is secured with tape or a transparent dressing
b. Immediately after the catheter punctures the skin
c. Immediately after observing a "flashback" of blood in the catheter
d. After a "flashback" of blood is observed and the catheter has been
advanced off the stylet
Ans: D (The tourniquet is released after a "flashback" of blood
is observed in the catheter's flashback chamber and the
catheter has been advanced off the stylet until the catheter hub
rests at the venipuncture site. Releasing the tourniquet restores
blood flow to the arm. If the tourniquet is released too soon,
the vein will collapse, making insertion more difficult.)
