1 CVS Pathology - Lecture 3 - MCQ Dr Mustafa Elsudani 1. Circulation and impaction of insoluble material in the circulation iscalled:- a) Toxemiab) Infarctionc) Embolusd) Boile) Apoptosis 2. Embolus means:- a) Detached intravascular solid, liquid or gaseous mass that is carried by the blood to asite distant from its point of originb) Detached intravascular solid mass only that is carried by the blood to a site distantfrom its point of originc) Only intravascular insoluble liquid that is carried by the blood to a site distant fromits point of origind) Only intravascular gas that is carried by the blood to a site distant from its point oforigine) None of the above 3. Which of the followings is not a type of embolus:- a) Airb) Thromboticc) Amniotic fluidd) Viruse) Fat
2 4. The commonest type of emboli is:- a) Fat embolib) Air embolic) Thromboticd) Parasitice) Tumor 5. An embolus rising from a thrombus in the leg vein will be impacted in:- a) Lungb) Heartc) Kidneyd) Braine) Liver 6. Emboli which impact in the arterial side of the circulation generallyoriginate from:- a) Right atriumb) Right ventriclec) Leg veinsd) Pelvic veinse) Left side of the heart 7. An embolus in the arterial system may originate from:- a) Atheroma in pulmonary arteryb) Infarct of left ventriclec) A venous thrombus in patient with normal heartd) A prosthetic pulmonary valvee) Air entering a venous cannula
3 8. When a left ventricular mural thrombus develops, embolism may result inall of the following organs except:- a) Brainb) Kidneysc) Lungsd) Small intestinee) Spleen 9. The effect of the detached non-septic thrombus depends mainly on:- a) The organ affectedb) The size of the vessel in which the thrombus formedc) The size of the detached thrombusd) All of the abovee) None of the above 10.The commonest source of pulmonary emboli is:- a) Thrombosed varicose veinsb) Deep veins of the leg (DVT)c) Thrombophlebitisd) Puerperal sepsise) Osteomyelitis 11.If the following events are placed in correct order which will come fourth:- a) Major abdominal surgeryb) Deep venous thrombosisc) Embolizationd) Pulmonary infarctione) Stasis in the calf veins
4 12.If the following events are placed in their correct order which will comefourth:- a) Pulmonary infarctionb) Prolonged bed restc) Pulmonary embolismd) Deep vein thrombosise) Fracture neck of femur 13.If the following events are placed in their correct order which will comefourth:- a) Pyemic abscess in the lungb) Septic thrombophlebitisc) Leg woundd) Septic embolie) Septic inflammation of the wound 14.Sequelae of pulmonary embolism include all of the followings except:- a) Sudden deathb) Pulmonary infarctionc) Pulmonary HTNd) Right sided HFe) Interstitial emphysema 15.Fracture of long bones of the lower limb predispose to:- a) Air embolism.b) Fat embolism.c) Nitrogen embolism.d) Parasitic embolisme) Tumor embolism
5 16.An 18 year old male has fracture femur. 48 hours later he felt pain in thechest with dyspnea, cyanosis and hemoptysis. Then he died. The mostpossible cause of death is:- a) Chronic venous congestion of the lungb) Fat embolism in pulmonary arteryc) Myocardial infarctiond) Thrombotic pulmonary embolisme) Chronic heart failure 17.The most common cause of clinically significant fat embolism is:- a) Abdominal surgeryb) Pancreatitisc) Diabetes insipidusd) Fracture of long bonese) Traumatized fatty liver 18.During routine vaginal delivery of a term infant, A 23 year old femalewith an uncomplicated pregnancy developed sudden dyspnea with cyanosisand hypotension. The most probable cause is:- a) Fat embolismb) Thromboembolismc) Gas embolismd) Amniotic fluid embolisme) Foreign body embolism 19.Each of the following pairs is correctly associated except:- a) Air embolism – Deep sea divingb) Multiple aseptic arterial embolism – Pyemic abscessesc) Fat embolism – Fracture of long bonesd) Amniotic fluid embolism – Child birthe) Venous embolism – post operative state
6 20- What is ischemic death (necrosis) of tissues:- a) Ischemiab) Infarctionc) Atheromad) Caisson diseasee) Embolism 21.Infarction occurs due to:- a) Sudden incomplete obstruction of blood supplyb) Gradual complete obstruction of blood supplyc) Sudden complete obstruction of blood supplyd) All of the above 22.All of the following cause infarction except:- a) Local arterial obstructionb) Thrombosisc) Atherosclerosisd) Diminished clotting factorse) Embolism 23.The following are factors that influence the development of an infarctexcept:- a) The nature of vascular supplyb) The rate at which occlusion developsc) Vulnerability to hypoxiad) Race and geographic distributione) Acute local vascular obstruction
