    Shock is best defined as:

    • A state of hypoperfusion of tissues with blood, caused by one of three mechanisms

    • A state of hyperperfusion of tissues with blood, caused by one of three mechanisms

    • A state of confusion, because I'm not sure which is which

    Correct Answer
    A. A state of hypoperfusion of tissues with blood, caused by one of three mechanisms
    Explanation
    Shock is best defined as a state of hypoperfusion of tissues with blood, caused by one of three mechanisms. This means that shock occurs when there is inadequate blood flow to the tissues, leading to a decrease in oxygen and nutrient supply. It can be caused by three mechanisms: inadequate cardiac output, blood volume loss, or vasodilation. Inadequate cardiac output can occur due to heart failure or arrhythmias, blood volume loss can be caused by hemorrhage or dehydration, and vasodilation can result from sepsis or anaphylaxis. Overall, shock is characterized by a decrease in tissue perfusion, which can have serious consequences if not promptly treated.

    ____________ originate in the left atrium or ventricle, aorta and major arteries; carried by arterial blood; and are important causes of Infarction.

    • Arterial Emboli

    • Venous Emboli

    • Capillary Emboli

    • Seriously, this is a gimme

    Correct Answer
    A. Arterial Emboli
    Explanation
    Arterial emboli originate in the left atrium or ventricle, aorta, and major arteries. They are carried by arterial blood and can cause infarction. Infarction refers to the death of tissue due to a lack of blood supply. Arterial emboli are formed by blood clots or other debris that break off from their original location and travel through the bloodstream. Once they reach a smaller blood vessel, they can block the blood flow, leading to tissue damage and infarction.

    True or False.  Paradoxical Emboli are venous emboli that reach the arterial circulation through the foramen ovale or an interventricular septal defect, that can cause Sx similar to those of arterial emboli.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Paradoxical emboli are venous emboli that can bypass the lungs and enter the arterial circulation through a communication between the right and left sides of the heart, such as the foramen ovale or an interventricular septal defect. This can lead to symptoms similar to those of arterial emboli, as the emboli can travel to various organs and cause ischemia. Therefore, the statement is true.

  • 5. 

    Sources of arterial emboli include:

    • Carotid artery

    • Mural thrombus

    • Endocarditis

    • Aortic Atherosclerosis

    • All of the above

    Correct Answer
    A. All of the above
    Explanation
    The correct answer is "All of the above." This is because all of the listed options can be sources of arterial emboli. The carotid artery, when affected by atherosclerosis or other conditions, can lead to the formation of emboli. Mural thrombus refers to a blood clot that forms on the inner wall of a blood vessel, which can also break off and cause arterial emboli. Endocarditis, an infection of the heart's inner lining, can result in the formation of emboli. Aortic atherosclerosis, the buildup of plaque in the aorta, can also lead to the development of emboli. Therefore, all of these options are valid sources of arterial emboli.

    Myocardial infarcts cannot be repaired except by replacement of damaged cells with fibrous tissue.  This results in:

    • Myocardial fibrosis and scarring

    • Myocardial necrosis and infection

    • Myocardial atrophy and scarring

    • Myocardial infection and necrosis

    Correct Answer
    A. Myocardial fibrosis and scarring
    Explanation
    Myocardial infarcts, commonly known as heart attacks, occur when the blood supply to the heart muscle is blocked, leading to the death of heart muscle cells. Unlike other tissues in the body, the heart muscle has limited ability to regenerate or repair itself. Therefore, when heart muscle cells are damaged during a myocardial infarction, they are replaced by fibrous tissue instead of new healthy muscle cells. This process of replacement with fibrous tissue leads to myocardial fibrosis and scarring, which can further impair the heart's function.

    • Solid Particle Emboli

    • Pulmonary Emboli

    • Paradoxical Emboli

    • Arterial Emboli

    • Gaseaous Emboli

    Correct Answer
    A. Gaseaous Emboli
    Explanation
    The correct answer is Gaseous Emboli. This is because injecting air into veins can lead to the formation of air bubbles, which can travel through the bloodstream as gaseous emboli. These emboli can block blood flow and cause damage to organs and tissues.

    Which best describes the result of an embolus that lodges in one of the mjor intestinal arteries, causing gangrene and necrosis of the bowel?

    • Splenic infarcts

    • Renal infarcts

    • Cerebral infarcts

    • Intestinal infarcts

    Correct Answer
    A. Intestinal infarcts
    Explanation
    When an embolus lodges in one of the major intestinal arteries, it can block the blood flow to the bowel, leading to gangrene and necrosis. This condition is known as intestinal infarcts. Splenic infarcts refer to the blockage of blood flow to the spleen, renal infarcts refer to the blockage of blood flow to the kidneys, and cerebral infarcts refer to the blockage of blood flow to the brain. However, in this scenario, the embolus specifically affects the intestinal arteries, resulting in intestinal infarcts.

    The most common form of emboli that represent fragments of thrombi carried by venous or arterial blood is best known as:

    • Embolus

    • Venous Emboli

    • Thromboemboli

    • Fat emboli

    • Saddle emboli

    Correct Answer
    A. Thromboemboli
    Explanation
    Thromboemboli is the correct answer because it refers to the most common form of emboli, which are fragments of thrombi that are carried by venous or arterial blood. Thromboemboli can cause blockages in blood vessels, leading to serious complications such as stroke or pulmonary embolism. The term "embolus" refers to any foreign material that travels through the bloodstream and causes a blockage, while "venous emboli" specifically refers to emboli that originate in the veins. "Fat emboli" and "saddle emboli" are less common forms of emboli that have specific characteristics and origins.

    Cellular hypoxia causes a shift from aerobic to anaerobic metabolism with an increased production in what?

    • Metabolic acidosis

    • Lactic acid

    • Respiratory acidosis

    • Pyruvic acid

    Correct Answer
    A. Lactic acid
    Explanation
    Cellular hypoxia refers to a condition where there is a lack of oxygen supply to the cells. In such situations, the cells switch from aerobic metabolism (which requires oxygen) to anaerobic metabolism (which does not require oxygen). This shift leads to an increased production of lactic acid. Lactic acid is a byproduct of anaerobic metabolism and its accumulation can result in metabolic acidosis. Therefore, the correct answer is lactic acid.

    Cecal volvulus, twisting of the mesentery and testicular torsion are examples of

    • Red infarcts

    • White infarcts

    • Honestly, the more you say infarct, its sounds like I farted

    Correct Answer
    A. Red infarcts
    Explanation
    Cecal volvulus, twisting of the mesentery, and testicular torsion are all examples of conditions that can lead to compromised blood supply to the affected organs. This compromised blood supply can result in tissue death, known as infarction. Red infarcts occur when there is venous occlusion or dual blood supply, allowing for the escape of blood and the formation of hemorrhage. In contrast, white infarcts occur when there is arterial occlusion and no collateral blood flow, leading to pale and ischemic tissue. Therefore, the correct answer is red infarcts.

    Fat Embolism Syndrome (FES) appears 1-3 days after fatty marrow into damaged blood vessels following severe trauma to fat-containing tissue and its most severe form is characterized by______________

    • Respiratory failure

    • CHF

    • Renal failure

    • Mental failure after behavioral health lecture

    Correct Answer
    A. Respiratory failure
    Explanation
    Fat Embolism Syndrome (FES) occurs when fat particles from the bone marrow enter the bloodstream after severe trauma to fat-containing tissue. These fat particles can block small blood vessels and cause damage to various organs. The most severe form of FES is characterized by respiratory failure, as the fat particles can obstruct blood flow to the lungs and impair oxygen exchange. This can lead to shortness of breath, low oxygen levels, and potentially life-threatening complications. Other symptoms may include confusion, petechial rash, and neurological abnormalities. Therefore, respiratory failure is the most appropriate choice to complete the given statement.

    Acute myocardial infarcts and splenic infarcts are examples of

    • Red infarcts

    • White infarcts

    • Did you just say fart?

    Correct Answer
    A. White infarcts
    Explanation
    Acute myocardial infarcts and splenic infarcts are examples of white infarcts. White infarcts occur when there is occlusion or blockage of an artery supplying an organ or tissue, leading to ischemia and subsequent tissue death. In these cases, the affected tissue appears pale or white due to the lack of blood supply. This is in contrast to red infarcts, which occur when there is reperfusion of blood into the previously ischemic tissue, causing hemorrhage and a red appearance.

    Rate this question:

  • 16. 

    Which embolus is particularly with long bone fractures?

    • Saddle embolus

    • Fat embolus

    • Liquid embolus

    • Solid particle embolus

    Correct Answer
    A. Fat embolus
    Explanation
    A fat embolus is particularly associated with long bone fractures. When a long bone is fractured, fat from the bone marrow can enter the bloodstream and travel to other parts of the body, causing a fat embolus. This can lead to symptoms such as shortness of breath, confusion, and even organ failure. Therefore, in the context of long bone fractures, a fat embolus is the most likely type of embolus to occur.

    • Angina

    • Thrombopenia

    • Embolism

    Correct Answer
    A. Infarction
    Explanation
    Infarction is the correct answer because it refers to the insufficiency of blood supply of sudden onset that leads to ischemic necrosis. It can be caused by either thrombosis or emboli and can occur in both arterial and venous systems. Ischemia refers to a lack of blood supply, but it does not necessarily result in necrosis. Angina refers to chest pain caused by inadequate blood flow to the heart. Thrombopenia is a condition characterized by a low platelet count. Embolism refers to the obstruction of a blood vessel by an embolus, which can be a blood clot or other foreign material.

    Which other organ cannot repair itself by regeneration, without fibrous scars forming and instead leaving behind a cyst filled with clear fluid?

    • Pancreas

    • Brain

    • Spleen

    • Liver

    • Kidney

    Correct Answer
    A. Brain
    Explanation
    The brain is the correct answer because unlike other organs such as the liver, kidney, and spleen, it cannot repair itself through regeneration without forming fibrous scars. Instead, when the brain is damaged, it often forms a cyst filled with clear fluid, which is a non-functional area of the brain. This lack of regenerative ability in the brain is one of the reasons why brain injuries and diseases can have long-lasting effects on cognitive and neurological functions.

    Major causes of shock include all of the following except

    • Internal or external hemorrhage

    • Severe trauma

    • Massive UTI

    • Extensive burns

    • Massive PE

    Correct Answer
    A. Massive UTI
    Explanation
    Shock is a life-threatening condition that occurs when there is inadequate blood flow to the body's organs and tissues. The major causes of shock include internal or external hemorrhage, severe trauma, extensive burns, and massive pulmonary embolism (PE). However, a massive urinary tract infection (UTI) is not typically considered a major cause of shock. While a severe UTI can cause systemic symptoms and complications, it is not commonly associated with the hypoperfusion of organs and tissues that characterizes shock.

    As a result of venous compression, this leads to:

    • Venous blockage, systemic ischemia, and necrosis

    • Venous occlusion, local anesthesia, and necrosis

    • Venous congestion, local ischemia, and necrosis

    • Venous congestion, arterial ischemia, and necrosis

    Correct Answer
    A. Venous congestion, local ischemia, and necrosis
    Explanation
    Venous compression refers to the narrowing or obstruction of a vein, leading to reduced blood flow. This results in venous congestion, which is the accumulation of blood in the affected area. The reduced blood flow can also cause local ischemia, which is the inadequate supply of oxygen and nutrients to the tissues. When tissues do not receive enough oxygen and nutrients, they can undergo necrosis, which is the death of cells or tissues. Therefore, the correct answer is venous congestion, local ischemia, and necrosis.

    The most common cause of death in ICU's is due to which type of shock?

    • Cardiogenic shock

    • Hypovolemic shock

    • Septic shock

    Correct Answer
    A. Septic shock
    Explanation
    Septic shock is the most common cause of death in ICU's. This type of shock occurs when an infection leads to a systemic inflammatory response, causing widespread damage to organs and tissues. It can result in severe hypotension and organ failure, leading to death if not promptly treated. Cardiogenic shock refers to a condition where the heart is unable to pump enough blood to meet the body's needs, while hypovolemic shock occurs due to a significant loss of blood or fluids. However, septic shock is the most prevalent cause of death in ICU settings.

    The most common reason for DIC, which is typical of Microvascular Thrombi, is due to:

    • Gram-positive sepsis

    • Gram-negative sepsis

    • Gram-positive coagulation

    • Gram-negative coagulation

    Correct Answer
    A. Gram-negative sepsis
    Explanation
    DIC, or disseminated intravascular coagulation, is a condition characterized by the abnormal formation of blood clots throughout the body's blood vessels. Gram-negative sepsis refers to a severe infection caused by gram-negative bacteria, which can trigger an excessive immune response and lead to DIC. These bacteria release endotoxins that activate the coagulation system, resulting in the formation of microvascular thrombi. Therefore, gram-negative sepsis is the most common reason for DIC, as stated in the given answer.

    Cardiogenic shock results in the loss of contractile elements deceasing the heart's ability to pump blood, leading to heart failure and possible arrhythmia.  Similar consequences may result with:

    • Myocarditis, valvular heart disease or CHF

    • Peritonitis, arterial heart disease or ARDS

    • Myocarditis, peritonitis, or CHF

    • Myocarditis, valvular heart disease or PE

    Correct Answer
    A. Myocarditis, valvular heart disease or CHF
    Explanation
    Cardiogenic shock is a condition where the heart is unable to pump enough blood to meet the body's needs. This can occur due to various reasons, including myocarditis (inflammation of the heart muscle), valvular heart disease (abnormalities in the heart valves), or congestive heart failure (a chronic condition where the heart is unable to pump blood effectively). These conditions can all lead to a decrease in the heart's ability to contract and pump blood, resulting in heart failure and potentially causing arrhythmias. Therefore, myocarditis, valvular heart disease, or CHF can all have similar consequences as cardiogenic shock.

    • White infarcts; Red infarcts

    • Red infarcts; White infarcts

    • Layered infarcts; Red infarcts

    • Layered infarcts; White infarcts

    Correct Answer
    A. White infarcts; Red infarcts
    Explanation
    White infarcts are typical of arterial occlusion in solid organs such as the heart and kidneys. This is because arterial occlusion leads to ischemia and lack of oxygen supply to the affected tissue, resulting in pale or white infarcts. On the other hand, red infarcts are typical of venous obstruction involving the intestines or testes. Venous obstruction causes congestion and blood pooling in the affected tissue, leading to hemorrhagic or red infarcts.

    The vasoconstriction of renal blood vessels results in renal hypoperfusion and a decreased GFR, activates renin-angiotensin system, thus increasing the cardiac output and blood pressure. This stage of shock is reversible and treatable.

    • Cardiogenic stage

    • Nonprogressive stage

    • Progressive stage

    • Septic stage

    Correct Answer
    A. Nonprogressive stage
    Explanation
    In the nonprogressive stage of shock, the vasoconstriction of renal blood vessels leads to renal hypoperfusion and a decrease in glomerular filtration rate (GFR). This activates the renin-angiotensin system, which in turn increases cardiac output and blood pressure. This stage is reversible and treatable, meaning that with appropriate intervention, the body can recover from this state of shock.

    In the Progressive stage, ________ also has a depressive effect on the heart, further potentiating pump failure, favoring the formation of pulmonary edema and ARDS.

    • Lactic Acidosis

    • Metabolic Alkalosis

    • Metabolic Acidosis

    • Lactic Alkalosis

    Correct Answer
    A. Metabolic Acidosis
    Explanation
    In the Progressive stage, metabolic acidosis also has a depressive effect on the heart, further potentiating pump failure, favoring the formation of pulmonary edema and ARDS. Metabolic acidosis occurs when there is an excess of acid or a loss of bicarbonate in the body. This leads to a decrease in pH levels, causing various physiological effects. In the context of heart failure, metabolic acidosis can worsen the condition by negatively impacting cardiac function and contributing to the development of pulmonary edema and acute respiratory distress syndrome (ARDS).

    Rate this question:

  • 37. 

    Which organ is typically at risk for an arterial emboli?  Which artery is typically lodged?

    • Heart; left coronary artery

    • Spleen; splenic artery

    • Kidney; renal artery

    • Brain; middle cerebral artery

    • Penis; deep artery (ouch)!

    Correct Answer
    A. Brain; middle cerebral artery
    Explanation
    Arterial emboli occur when a blood clot or other debris travels through the bloodstream and becomes lodged in an artery, blocking blood flow to the affected organ. The brain is typically at risk for arterial emboli because it has a rich blood supply and is susceptible to blockages. The middle cerebral artery is the most commonly lodged artery in the brain, making it a common site for arterial emboli. This can lead to a stroke, as the blocked artery prevents oxygen and nutrients from reaching the brain tissue supplied by that artery.

    • Sharp axillary pain

    • Dull epigastric pain

    • Boring hypogastric pain

    • Sharp hyperchondriac pain

    Correct Answer
    A. Sharp subcostal pain
    Explanation
    Splen infarcts that are also susceptible to arterial emboli are usually associated with sharp subcostal pain. This type of pain is typically felt below the ribs on the left side of the body, indicating that the infarct is affecting the blood supply to the spleen. The sharp nature of the pain suggests a sudden interruption of blood flow, which can occur when an embolus blocks an artery supplying the spleen.

    Explanation
    Thrombi are blood clots that form within blood vessels. The two classifications of thrombi are based on their composition and appearance under a microscope. Red thrombi are composed of tightly intermixed red blood cells (RBCs) and fibrin. They are typically seen in veins and are associated with slow blood flow. Layered thrombi, on the other hand, have cellular elements and fibrin arranged in layers. These thrombi are typically seen in arteries and are associated with fast blood flow. Lines of Zahn are microscopic lines that are seen in layered thrombi and are indicative of their formation in flowing blood.

    The 4 types of Thrombi locations are:

    • Arterial, Venous, Capillary, Pre-capillary

    • Mural, Arterial, Venous, Capillary

    • Intramural, Arterial, Venous, Microvascular

    • Intravascular, Arterial, Venous, Macrovascular

    Correct Answer
    A. Intramural, Arterial, Venous, Microvascular
    Explanation
    The correct answer is Intramural, Arterial, Venous, Microvascular. Thrombi can form in different locations within the body's blood vessels. Intramural thrombi occur within the walls of blood vessels. Arterial thrombi form in arteries, which carry oxygenated blood away from the heart. Venous thrombi develop in veins, which transport deoxygenated blood back to the heart. Microvascular thrombi occur in the smallest blood vessels, such as capillaries, which are responsible for the exchange of oxygen and nutrients between the blood and surrounding tissues.

    True or False.  Hypotonic shock results from a loss of ciculatory volume, attributed to massive hemorrhage or to water loss related to a massive burn, vomiting, or diarrhea.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Should be Hypovolemic Shock. Hypotonic shock results from a loss of vascular tone and pooling of blood in dilated peripheral blood vessels.

    Arterial Emboli originate from common causes of ischemia in various organs and most originate from the __________ or from _________ thrombi.

    • Aorta; arterial

    • Epithelial tissue; tricuspid

    • Endocardium; valvular

    • Myocardium; tubular

    • Pericardium; valvular

    Correct Answer
    A. Endocardium; valvular
    Explanation
    Arterial emboli are blood clots that form in the endocardium, the inner lining of the heart, and can travel through the bloodstream to block arteries in various organs. They can also originate from valvular thrombi, which are blood clots that form on the heart valves. These common causes of ischemia can lead to reduced blood flow and potential damage to organs.
