Question 1

A systemic infection may put a patient at risk for:

A)Thrombocytopenia
B)Disseminated intravascular coagulation
C)Atrial fibrillation
D)Leukopenia

Answer 1

B
Disseminated intravascular coagulation is an uncommon consequence of a systemic infection. Systemic infections do not increase the risk of atrial fibrillation, thrombocytopenia, or leukopenia.

Question 2

When collecting a sample for PT/INR testing using the CoaguChek S instrument, a blue-top tube containing sodium citrate is used.

Answer 2

False
The CoaguChek S instrument uses samples obtained via capillary puncture, not tubes of blood collected via venipuncture.

A.Fast-acting anticoagulant administered via IV or injection
B.Enzyme that assists with dissolution of blood clots
C.Numerical measurement of breakdown products created with blood clot dissolution

E.Oral anticoagulant; levels monitored with INR test
Coumadin

Answer 3

E

Question 7

Match the correct definition to the items listed below.
A.Fast-acting anticoagulant administered via IV or injection
B.Enzyme that assists with dissolution of blood clots

Which of these test results are used to monitor oral anticoagulant use and to assist with the decision making when considering medication level changes?

A)INR
B)aPTT
C)FDP
D)Plt Ct
E)PT

Question 12

Fibrin degradation products:

A)Increase the rate of blood clotting
B)Are present in the bloodstream with clot dissolution
C)Line the interior of all blood vessels
D)Act as anticoagulants

Question 13

Match the correct definition to the items listed below.
A.Fast-acting anticoagulant administered via IV or injection
B.Enzyme that assists with dissolution of blood clots
C.Numerical measurement of breakdown products created with blood clot dissolution
D.Screening coagulation test for intrinsic clotting cascade problems
E.Oral anticoagulant; levels monitored with INR test
Plasmin

Question 14

The extrinsic pathway for blood clotting utilizes chemicals that are released into the bloodstream as a result of the vessel injury.

Question 15
