Question:
3. The patient has been taking blood thinners for some time.
The phlebotomist asks the patient to hold pressure on the site
after the needle is removed. As the phlebotomist is labeling
the tubes, he notices that the gauze at the site is soaked in
blood. Which of the following should the phlebotomist do
first?
A. Apply an ice pack
B. Call for help.
C. Replace the gauze and hold pressure.
D. Elevate the arm and apply a pressure bandage.
Answer:
Replace the gauze and hold pressure
It is the responsibility of the phlebotomist to assure that bleeding has completely
stopped after completion of the venipuncture before bandaging (use a pressure
bandage such as Coban) and releasing the patient. The gauze should be replaced and
extra pressure applied for at least 5 minutes. An ice pack will not help stop bleeding but
may keep a hematoma from forming. Elevating the arm while applying pressure might
help as long as bleeding does not resume when the arm is lowered. The phlebotomist
should not hesitate to call for assistance if needed.
Question:
4. Which of the following special precautions should be taken
when drawing blood samples from a patient on heparin
therapy?
A. Use light to moderate tourniquet pressure.
B. Apply site pressure for a prolonged time.
C. Avoid using the basilic vein
D. Avoid using 21 gauge needles.
Answer:
,Apply site pressure for a prolonged time.
Patients are given heparin therapy to prevent the formation of venous thrombi (clots).
When venipunctures are performed, these patients tend to bleed longer after the
procedure. Additional pressure should be applied to the site and the patient should not
be released until stoppage of bleeding has been confirmed. The basilic vein should be
avoided if possible, not because of heparin therapy, but due to the fact that it is located
close to an artery and nerves. A 21 gauge needle is typically used but a 22 or 23 might
suffice, leaving a smaller puncture at the venipuncture site. Light to moderate tourniquet
pressure might not render the veins adequately accessible.
Question:
5. Following an uncomplicated venipuncture, the patient is still
bleeding after three minutes of continuous pressure by the
phlebotomist. The phlebotomist asks the patient if she is on
anticoagulants. The patient indicates that she is, and states that
this is normal for her. How should the phlebotomist proceed?
A. Apply a pressure bandage and let the patient leave.
B. Bend the arm up, apply a pressure bandage, wait two more
minutes, and notify the nurse.
C. Hold direct pressure for five more minutes, apply a
bandage, and let the patient leave.
D. Hold direct pressure until the bleeding stops, apply a
bandage, and notify the nurse.
Answer:
Hold direct pressure until the bleeding stops, apply a bandage, and notify the nurse.
It is the responsibility of the phlebotomist to ensure bleeding has stopped before leaving
the patient then notifying the nurse. In addition, if bruising had occurred at the site,
nursing staff will want to know the source for documentation and follow up purposes.
Question:
6. A patient is scheduled to have her blood collected to
evaluate Coumadin (warfarin) therapy. Which of the following
actions should the phlebotomist take when performing a
venipuncture on this patient? (Select the three (3) correct
, answers.)
A. Collect PTT in a light blue tube.
B. Collect PT/INR in a light blue tube.
C. Apply firm and direct pressure to the venipuncture site for
at least 5 minutes.
D. Inform the patient about possible hematoma formation.
E. Apply a pressure bandage immediately after venipuncture.
Answer:
Collect PT/INR in a light blue tube.
Apply firm and direct pressure to the venipuncture site for at least 5 minutes., Inform
the patient about possible hematoma formation.
The test that monitors coumadin (warfarin) therapy is the prothrombin time (PT/INR)
which is drawn into a light blue tube. Patients receiving this therapy tend to bleed longer
after venipuncture, so applying firm and direct pressure to the site for at least 5 minutes is
necessary. A pressure bandage such as Coban may be applied before releasing the
patient, who should be informed about possible hematoma formation. Applying the
pressure bandage immediately after the venipuncture leaves the patient open to
formation of a hematoma and possibly compartment syndrome.
Question:
7. Which of the following is the key element in effective
communication?
A. eye contact
B. personal space
C. active listening
D. body language
Answer:
active listening
Effective communication involves the interaction of two people. The listener must focus
on what is being said and give feedback to the speaker to assure understanding. This is
known as active listening. Making eye contact and non-threatening use of personal space
are aspects of body language. Studies have shown that 55% of communication is body
language, 38% is the tone of voice, and 7% is the actual words spoken.
