Decreased platelet count brought on by heparin treatment

Correct! Wrong!

Heparin-induced thrombocytopenia (HIT) is a potentially serious immune-mediated reaction that leads to a decreased platelet count (thrombocytopenia) in response to heparin treatment. Heparin is an anticoagulant medication commonly used to prevent blood clot formation. However, in some individuals, the use of heparin can trigger an immune response that leads to the destruction of platelets and an increased risk of abnormal clot formation.

Meningitis characterized by high total protein, low glucose levels, lactate levels below 35mg/dL

Correct! Wrong!

Fungal meningitis is an infection of the meninges (the protective membranes surrounding the brain and spinal cord) caused by various types of fungi. It can lead to specific changes in the composition of cerebrospinal fluid (CSF), which can be observed through CSF analysis.

Increase in number of neutrophilic leukocytes in blood/tissue. aka neutrocytosis, neutrophil leukocytosis

Correct! Wrong!

Neutrophilia, also known as neutrocytosis or neutrophil leukocytosis, refers to an increase in the number of neutrophilic leukocytes (neutrophils) in the blood or tissues. Neutrophils are a type of white blood cell that plays a critical role in the body's immune response against bacterial infections. Neutrophilia is often a sign that the body is responding to an infection or inflammation.

Test which use thromboplastin and calcium as reactants to see how fast plasma in blood clots

Correct! Wrong!

The test you are referring to is indeed the Prothrombin Time (PT) test. The PT test measures the time it takes for blood plasma to clot in response to the addition of thromboplastin and calcium. Thromboplastin is a mixture of proteins that initiates the coagulation cascade, leading to the formation of a blood clot. Calcium is an essential component of this process, as it helps facilitate the various enzymatic reactions that lead to clot formation.

Anemia as result of inhibition of DNA synthesis during RBS production

Correct! Wrong!

Megaloblastic anemia is a type of anemia that results from impaired DNA synthesis during the production of red blood cells (RBCs), leading to the formation of abnormally large and immature RBCs called megaloblasts.

Condition where the body produces too few platelets

Correct! Wrong!

It seems like there might be a small confusion in your response. Thrombotic thrombocytopenic purpura (TTP) is actually a condition characterized by the formation of small blood clots throughout the body, leading to a low platelet count (thrombocytopenia). TTP is caused by a deficiency of an enzyme called ADAMTS13, which is responsible for breaking down large von Willebrand factor (vWF) multimers in the blood.

Cancer characterized by plasma cells (involved in immune responce) grow out of control.

Correct! Wrong!

Multiple myeloma is a type of cancer characterized by the uncontrolled growth of plasma cells, which are a type of white blood cell involved in the immune response. Plasma cells are responsible for producing antibodies, which play a crucial role in fighting infections.

CSF pigmentation due to subarachnoid hemorrhage

Correct! Wrong!

Chronic systemic sclerosis characterized by hardening of the skin and internal organs

Correct! Wrong!

Scleroderma, also known as systemic sclerosis, is a rare autoimmune disorder characterized by the hardening (fibrosis) of connective tissues, which can affect the skin, blood vessels, and internal organs. It is a chronic condition that can vary widely in its presentation and severity.

Local coagulation. clotting of blood in part of circulatory system

Correct! Wrong!

Thrombosis refers to the formation of a blood clot (thrombus) within a blood vessel, resulting in local coagulation of blood in part of the circulatory system. Thrombosis can occur in both arteries and veins and has the potential to disrupt blood flow, leading to various complications.

Malignant tumor formed of grandular structures in epithelial tissue

Correct! Wrong!

An adenocarcinoma is a type of malignant tumor that originates from glandular structures within epithelial tissue. Epithelial tissue lines various surfaces and structures in the body and forms glands that secrete substances. Adenocarcinomas specifically arise from cells that have glandular properties and produce mucus or other fluids.

blood coagulation test that analyzes the effects of heparin treatment to detect anomalies in blood clotting

Correct! Wrong!

The activated partial thromboplastin time (APTT) is a blood coagulation test used to assess the effects of heparin treatment and to detect anomalies in blood clotting, particularly in the intrinsic pathway of the coagulation cascade.

Abnormally low blood count of neutrophils(WBC)

Correct! Wrong!

Neutropenia refers to an abnormally low blood count of neutrophils, which are a type of white blood cell (WBC) involved in the immune response and defense against bacterial infections. Neutropenia can increase the risk of infections, as neutrophils play a crucial role in fighting off harmful microorganisms.

A colorless result of lowering bilirubin. Urobilinogen is more concentrated in the intestines as a result of hemolysis.

Correct! Wrong!

Urobilinogen is a colorless substance that forms when bilirubin, a yellow compound produced during the breakdown of hemoglobin in red blood cells, is metabolized by bacteria in the intestines. It plays a crucial role in the excretion of bilirubin from the body and can serve as an indicator of various medical conditions.

Medication for insulin secretion from the pancreas

Correct! Wrong!

Tolbutamide is indeed a medication used to stimulate insulin secretion from the pancreas. It belongs to a class of drugs known as sulfonylureas, which are commonly prescribed to manage type 2 diabetes. Sulfonylureas work by increasing the release of insulin from the beta cells in the pancreas, which helps lower blood sugar levels.

Anemia as result of inhibition of DNA synthesis during RBS production

Correct! Wrong!

Megaloblastic anemia is a type of anemia that results from impaired DNA synthesis during the production of red blood cells (RBCs), leading to the formation of abnormally large and immature RBCs called megaloblasts.
