In which stage of shock cellular and tissue injury is so severe that even if the hemodynamic defects are corrected, survival is not possible? *

Initial non-progressive stage

Progressive stage

Irreversible stage

All of these

Failure of myocardial pump resulting from intrinsic myocardial damage, extrinsic pressure, or obstruction to outflow will lead towards : 

Cardiogenic shock

Septic shock

Hypovolemic shock

Can't be predicted

A 68-year-old man develops sudden, severe substernal chest pain. Laboratory studies and ECG confi rm an acute myocardial infarct. Despite vigorous therapy, the patient cannot maintain his blood pressure and expires 24 hours later. A cross section of the left ventricle is examined at autopsy (shown in the image). The arrows point to a soft, yellow area of necrosis. Which of the following was the most likely cause of death?

Cardiogenic shock

Neurogenic shock

Hypovolemic shock

Septic shock

Thrombi occurring in heart chambers or in the aortic lumen are designated as : *

Mural Thrombi

Vegetations

Cardiac emboli

Leucoma

A 20-year-old man is brought to the emergency room after rupturing his spleen in a motorcycle accident. His blood pressure on admission is 80/60 mm Hg. Analysis of arterial blood gasses demonstrates metabolic acidosis. This patient is most likely suffering from which of the following conditions? *

Hypersplenism

Cardiogenic shock

Hypovolemic shock

Septic shock

Lines of Zahn represents: *

pale platelet and fibrin layers alternating with darker red cell–rich layers

pale platelet and albumin layers alternating with darker red cell–rich layers

Red platelet and fibrin layers alternating with lighter white cell–rich layers

Greenish platelet and fibrin layers alternating with lighter red cell–rich layers

Shock is defined as: *

a state in which increased cardiac output or reduced effective circulating blood volume impairs tissue perfusion and leads to cellular hypoxia

a state in which diminished cardiac output or reduced effective circulating blood volume impairs tissue perfusion and leads to cellular hypoxia

a state in which diminished cardiac output or reduced effective circulating blood volume increases tissue perfusion and leads to cellular hypoxia

a state in which diminished venous return or reduced effective circulating blood volume impairs tissue perfusion and leads to cellular hypoxia

A 92-year-old woman is brought unconscious to the emergency room from a nursing home. Her blood pressure is 70/30 mm Hg. She is febrile (38°C/100.5°F) and tachypneic. Laboratory studies demonstrate a WBC count of 22,000/μL with 92% neutrophils. Urinalysis reveals numerous Gram-negative organisms. Which of the following most likely accounts for this patient’s signs and symptoms? *

Cardiogenic shock

Hypovolemic shock

Septic shock

Neurogenic shock

Presence of generalized vasodilation due to type I hypersensitivity reaction is called : *

Neurogenic shock

Cardiogenic shock

Anaphylactic shock                                                                                           AHS pathology

Hypovolemic shock

The thrombus enlarges through the accretion of additional platelets and fibrin, known as: *

Propagation

Embolization

Dissolution

Organization

Older thrombi become .......... by the ingrowth of endothelial cells, smooth muscle cells, and fibroblasts. 

Embolized

Organized

Scarred

Dissemination

Sterile vegetations can  develop on noninfected  valves in hypercoagulable  states, these lesions are called : *

Vegetations

Nonbacterial thrombotic endocarditis

Infective endocarditis

Septicemia

If a thrombus is newly formed, activation of fibrinolytic factors may lead to its rapid shrinkage and complete............. *

Propagation

Dissolution

Organization

Which type of shock is triggered by microbial infections and is associated with severe systemic inflammatory response syndrome (SIRS)? *

Cardiogenic shock

Septic shock

Neurogenic shock

Hypovolemic shock

Atherosclerosis is a major cause of arterial thromboses because it is associated with the : *

loss of endothelial integrity and with abnormal blood flow

loss of stromal integrity and with abnormal blood flow

loss of stromal integrity and with normal blood flow

loss of epithelial integrity and with normal blood flow
