EXAM QUESTIONS
QUESTION 1
Hemostasis
CORRECT ANSWER
stoppage of bleeding
RATIONALE: Hemostasis is the correct answer because it refers to the process by which the body stops bleeding after an
injury, which is a fundamental concept in the field of biology and medicine. The key to understanding why "stoppage of
bleeding" is the correct answer lies in the root word "hemo," meaning blood, and "stasis," meaning to stand or cease,
which together form the term that describes this vital physiological process.
QUESTION 2
Thrombocytopenia
CORRECT ANSWER
low platelet count
Trusted by thousands of students and professionals worldwide Page 1 of 62
, RATIONALE: Thrombocytopenia refers to a condition characterized by a reduced number of platelets in the blood, which
is a critical factor in blood clotting and stopping bleeding. The term "thrombocytopenia" is derived from the Greek words
"thrombos" meaning clot and "cyte" meaning cell, with the suffix "-penia" indicating a deficiency or low count, making
"low platelet count" the correct interpretation of this term.
QUESTION 3
Virchow's triad
CORRECT ANSWER
venous stasis
endothelial injury
hypercoagulability
RATIONALE: Virchow's triad is a concept that explains the causes of thrombosis, and it is named after the 19th-century
pathologist Rudolf Virchow, who first proposed it. The triad is correct because it encompasses the three primary factors
that contribute to blood clot formation, which are alterations in blood flow (venous stasis), damage to the endothelial
lining of blood vessels (endothelial injury), and an imbalance in the coagulation process (hypercoagulability).
QUESTION 4
emboli
CORRECT ANSWER
clots that break loose and travel through circulation
RATIONALE: The term "emboli" specifically refers to blood clots that break loose from their site of formation and travel
through the bloodstream, lodging in a distant part of the circulatory system. This definition is rooted in the Greek word
"embolos," meaning "thing thrown in," which accurately describes the process of a clot being dislodged and carried away
by the blood flow.
QUESTION 5
deep venous thrombosis (DVT)
CORRECT ANSWER
blood clot formation in a deep vein, usually of the legs or pelvic region that lead to vena cava
RATIONALE: Deep venous thrombosis (DVT) is characterized by blood clot formation in a deep vein, typically in the legs
or pelvic region, which can travel to the inferior vena cava, a major vein that carries deoxygenated blood from the lower
body to the heart. This is the correct definition because it directly refers to the location and nature of the clot formation
that defines DVT, distinguishing it from other types of thrombosis.
QUESTION 6
PFO
CORRECT ANSWER
patent foramen ovale
Trusted by thousands of students and professionals worldwide Page 2 of 62
, RATIONALE: PFO stands for Patent Foramen Ovale, which is a medical term referring to a congenital opening in the
heart that fails to close after birth. This acronym is correct because it directly translates the Latin words "patent" (open),
"foramen" (hole), and "ovale" (oval), which are the key components of the medical condition.
QUESTION 7
VTE prophylaxis
CORRECT ANSWER
•Early mobilization
•Ted Hose
•SCDs
•Lovenox, Heparin
•ASA
RATIONALE: These options are the correct approach for VTE prophylaxis because they represent a combination of
mechanical (Ted Hose) and pharmacological (SCDs, Lovenox, Heparin, ASA) methods to reduce the risk of venous
thromboembolism, a common complication in hospitalized patients. Early mobilization is also a crucial aspect of VTE
prophylaxis as it helps to prevent blood stasis and clot formation.
QUESTION 8
Lovenox (enoxaparin)
CORRECT ANSWER
low molecular weight heparin
Trusted by thousands of students and professionals worldwide Page 3 of 62
, RATIONALE: Lovenox (enoxaparin) is a correct example of a low molecular weight heparin because it has a smaller
molecular size compared to unfractionated heparin, allowing for more predictable and controlled anticoagulant effects.
This characteristic is a defining feature of low molecular weight heparins, which distinguish them from unfractionated
heparins.
QUESTION 9
partial occulsion
CORRECT ANSWER
blood flow partially occluded by a thrombus
