#1
Which protein is primarily responsible for the formation of blood clots?
Fibrinogen
ExplanationFibrinogen forms fibrin strands, the backbone of blood clots.
#2
What is the medical term for a blood clot that forms in a deep vein, usually in the legs?
Deep vein thrombosis
ExplanationDeep vein thrombosis occurs typically in the lower extremities and can lead to serious complications.
#3
What is the role of platelets in blood clotting?
Forming a plug at the site of injury
ExplanationPlatelets adhere to injured blood vessels and aggregate to form a temporary plug.
#4
Which vitamin plays a crucial role in blood clotting?
Vitamin K
ExplanationVitamin K is necessary for the synthesis of clotting factors.
#5
Which of the following conditions is commonly associated with an increased risk of developing blood clots?
Atrial fibrillation
ExplanationAtrial fibrillation disrupts blood flow, predisposing individuals to clot formation.
#6
Which of the following is not a risk factor for developing blood clots?
Regular exercise
ExplanationRegular exercise promotes healthy blood circulation, reducing the risk of blood clots.
#7
What is the main purpose of anticoagulant medications?
To prevent the formation of new blood clots
ExplanationAnticoagulants inhibit clotting factors to prevent new blood clot formation.
#8
What is the term used to describe a condition where blood clots occur in small blood vessels throughout the body?
Disseminated intravascular coagulation (DIC)
ExplanationDIC involves widespread activation of coagulation, leading to excessive clot formation.
#9
Which of the following medications is commonly used as an anticoagulant?
Warfarin
ExplanationWarfarin inhibits vitamin K-dependent clotting factors.
#10
Which of the following is a potential complication of untreated deep vein thrombosis?
Pulmonary embolism
ExplanationClots from deep vein thrombosis can dislodge and travel to the lungs, causing pulmonary embolism.
#11
Which of the following conditions is characterized by an excessive tendency to bleed and difficulty forming blood clots?
Hemophilia
ExplanationHemophilia results from a deficiency in clotting factors, leading to bleeding disorders.
#12
What is the primary treatment for a pulmonary embolism?
Anticoagulant medication
ExplanationAnticoagulants prevent further clotting and reduce the risk of pulmonary embolism recurrence.
#13
Which of the following is a genetic risk factor for blood clotting disorders?
Factor VIII deficiency
ExplanationFactor VIII deficiency is a genetic condition leading to hemophilia A.
#14
What is the primary goal of treatment for a person with hemophilia?
Prevent excessive bleeding
ExplanationTreatment aims to replace deficient clotting factors or enhance their function to prevent bleeding.
#15
Which of the following conditions is characterized by a deficiency in a specific clotting factor?
Hemophilia
ExplanationHemophilia results from deficiencies in specific clotting factors, leading to impaired coagulation.
