REMOVAL OF PLASMA AND COMPONENTS

Answer 1

platelet pheresis
leukapheresis
plasmapheresis
stem cell harvest
erythrocytapheresis

Question 2

BLOOD DONATION

 To protect both the donor and the recipients,

Answer 2

all
prospective blood donors must complete a
questionnaire and be examined and interviewed
before donating their blood.

Question 3

blood donation criteria

Answer 3

Different criteria exist for the donation of red cells
and plasma.
 Body weight should exceed 50 kg for a standard 470
mL donation.
 Donors must be between the ages of 16 and 70 years

Question 4

BLOOD TRANSFUSION

What do you check besides the 5 rights when administering blood?

Answer 4

 Check patient has a patent cannula before priming blood in infusion set.
[Change IV tubing every 12 h, or with new IV fluids, with a platelet
transfusion or on completion of transfusion, whichever comes first].
 Check patient has given consent
 Make sure that PRBC transfusion is initiated within 30 min after removal of
the PRBCs from the blood bank refrigerator.
 Check details of prescription/order against the blood bag AND the product
compatibility report, (Blood group, Rh factor)
 Check the blood for gas bubbles and any unusual colour or cloudiness. (Gas
bubbles may indicate bacterial growth. Abnormal colour or cloudiness may
be a sign of haemolysis.)
 Check use by date
 Check temperature (should not be cold/incorrectly stored)

Question 5

Pharmacological agents to stimulate production of one or more
types of blood cells by the marrow are commonly used.

Answer 5

(Growth
factors, erythropoietin, thrombopoeitin, iron replacement
therapy)

Question 6

who outline appropriate assessment and

interventions in order to address anomalies (blood)

Answer 6

The Australian National Blood Authority Patient Blood

Management Guidelines

Question 7

 Researchers continue to seek a blood substitute

Answer 7

that is practical
and safe. Manufacturing artificial blood is problematic, given the
myriad functions of blood components.

Question 8

Desmopressin

Answer 8

is a synthetic hormone that may help control bleeding. It
can be injected intravenously, administered under the skin
(subcutaneously), or given as a nasal spray. Desmopressin does not work
for every platelet disorder or individual.

Question 9

Desmopressin works on

Answer 9

is used to help stop bleeding in patients with

von Willebrand’s disease or mild haemophilia A.

Question 10

DDAVP causes the release o

Answer 10

f von Willebrand’s antigen from the platelets
and the cells that line the blood vessels where it is stored. Von
Willebrand’s antigen is the protein that carries factor VIII. This increase
in von Willebrand’s antigen and factor VIII helps to stop bleeding
