during chemical injury?

Question 2 options:

Enzymatic digestion of the nucleus and nucleolus occurs, halting deoxyribonucleic acid (DNA) synthesis. Influx of potassium ions into the mitochondria occurs, halting the adenosine triphosphate (ATP) production. Edema of the Golgi body occurs, preventing the transport of proteins out of the cell.

Advanced Pathophysiology

In hypoxic injury, sodium enters the cell and causes swelling

because:

Advanced Pathophysiology Epinephrine bound to mast cells Acetylcholine bound to mast cells Save Question 6 (5 points)

What is the mechanism that results in type II hypersensitivity

reactions?

Question 6 options:

Antibodies coat mast cells by binding to receptors that signal its degranulation, followed by a discharge of preformed mediators. Antibodies bind to soluble antigens that were released into body fluids, and the immune complexes are then deposited in the tissues. Cytotoxic T (Tc) lymphocytes or lymphokine-producing helper T 1 (Th1) cells directly attack and destroy cellular targets. Antibodies bind to the antigens on the cell surface. Save Question 7 (5 points)

Type III hypersensitivity reactions are a result of which of the

following?

Question 7 options:

Antibodies coating mast cells by binding to receptors that signal its degranulation, followed by the discharge of preformed mediators Antibodies binding to soluble antigens that were released into body fluids and the immune complexes being deposited in the tissues Cytotoxic T (Tc) cells or lymphokine-producing helper T 1 (Th1) cells directly attacking and destroying cellular targets

Advanced Pathophysiology Antibodies binding to the antigen on the cell surface Save Question 8 (5 points)

Tissue damage caused by the deposition of circulating

immune complexes containing an antibody against the host

deoxyribonucleic acid (DNA) is the cause of which disease?

Question 8 options:

Hemolytic anemia Pernicious anemia Systemic lupus erythematosus Myasthenia gravis Save Question 9 (5 points)

Why does tissue damage occur in acute rejection after organ

transplantation?

Question 9 options:

Th1 cells release cytokines that activate infiltrating macrophages, and cytotoxic T (Tc) cells directly attack the endothelial cells of the transplanted tissue. Circulating immune complexes are deposited in the endothelial cells of transplanted tissue, where the complement cascade lyses tissue. Receptors on natural killer (NK) cells recognize antigens on the cell surface of the transplanted tissue, which releases lysosomal enzymes that destroy tissue. Antibodies coat the surface of the transplanted tissue to which mast cells bind and liberate preformed chemical mediators that destroy tissue. Save

Advanced Pathophysiology

Regarding the endothelium, what is the difference between

healthy vessel walls and those that promote clot formation?

What is the expected electrocardiogram (ECG) pattern when a

thrombus in a coronary artery permanently lodges in the

vessel and the infarction extends through the myocardium

from the endocardium to the epicardium?

Question 13 options:

Prolonged QT interval ST elevation myocardial infarction (STEMI) ST depression myocardial infarction (STDMI) Non-ST elevation myocardial infarction (non-STEMI) Save Question 14 (5 points)

A patient reports sudden onset of severe chest pain that

radiates to the back and worsens with respiratory movement

and when the patient is lying down. These clinical

manifestations describe:

Advanced Pathophysiology

Question 14 options:

Myocardial infarction (MI) Pericardial effusion Restrictive pericarditis Acute pericarditis Save Question 15 (5 points)

Respirations that are characterized by alternating periods of

deep and shallow breathing are a result of which respiratory

mechanism?

Question 15 options:

Decreased blood flow to the medulla oblongata Increased partial pressure of arterial carbon dioxide (PaCO2), decreased acid-base balance (pH), and decreased partial pressure of arterial oxygen (PaO2) Stimulation of stretch or J-receptors Fatigue of the intercostal muscles and diaphragm Save Question 16 (5 points)

Which cytokines activated in childhood asthma produce an

allergic response?

cystic fibrosis?

Question 19 options:

What is a consequence of plasma membrane damage to the

mitochondria?

Question 22 options:

Enzymatic digestion halts deoxyribonucleic acid (DNA) synthesis. Influx of calcium ions halts adenosine triphosphate (ATP) production. Edema from an influx in sodium causes a reduction in ATP production. Potassium shifts out of the mitochondria, which destroys the infrastructure. Save Question 23 (5 points)

During cell injury caused by hypoxia, sodium and water move

into the cell because:

Question 36 options:

Potassium moves out of the cell, and potassium and sodium are inversely related. The pump that transports sodium out of the cell cannot function because of a decrease in adenosine triphosphate (ATP) levels.
