MDS PREP
The most important aspect in treating Disseminated intravascular Coagulation (DIC) is to
1) Administer heparin
2) Administer platelets
3) Treat the underlying disease process
4) Achieve normal levels of fibrinogen
General Medicine
Answer: 3
DIC is a serious condition characterized by the widespread activation of the coagulation cascade, leading to the formation of blood clots throughout the small blood vessels. This can result in organ dysfunction and bleeding. The most critical step in managing DIC is to identify and treat the underlying cause (such as infection, trauma, or malignancy) because addressing the root issue can help resolve the coagulation abnormalities.
What is the role of tissue plasminogen activator (tPA) in the treatment of pulmonary embolism?
1) Prevents thrombus formation
2) Dissolves existing thrombi
3) Inhibits platelet aggregation
4) Enhances fibrinolysis
tPA is a thrombolytic agent used to dissolve blood clots. In the treatment of pulmonary embolism, it is administered to break down the clot in the pulmonary artery, thereby improving blood flow and reducing the risk of complications.

Which of the following is a common dietary saturated fatty acid?
1. Oleic acid
2. Stearic acid
3. Linolenic acid
4. Arachidonic acid
Biochemistry
Answer: 4
Saturated fatty acids are a type of fat that has a chemical structure with a
single bond between each carbon atom in the fatty acid chain and no double
bonds. These types of fats are typically solid at room temperature. Out of the
given options, stearic acid (C18:0) is the only saturated fatty acid. The others
are:
1. Oleic acid (C18:1) is a monounsaturated fatty acid, which means it has one
double bond. It is commonly found in olive oil, canola oil, and avocados.
2. Linolenic acid (C18:3) is a polyunsaturated fatty acid, specifically an
omega-3 fatty acid, with three double bonds. It is found in plant sources like
flaxseeds, chia seeds, and walnuts.
3. Arachidonic acid (C20:4) is also a polyunsaturated fatty acid, an omega-6
fatty acid with four double bonds. It is found in animal fats, such as meat, and
in smaller amounts in some plant oils like sunflower oil and peanut oil.
Stearic acid, on the other hand, is a common saturated fatty acid found in
various animal fats and certain vegetable oils like coconut oil, palm kernel
oil, and cocoa butter. It is known for its role in the structure of cell
membranes and as a precursor for the biosynthesis of cholesterol in the body.
While it is important to consume fatty acids for good health, excessive
consumption of saturated fatty acids has been associated with higher levels of
LDL (low-density lipoprotein) cholesterol, which is often referred to as "bad"
cholesterol, and an increased risk of heart disease. However, it is important to
maintain a balanced diet that includes both saturated and unsaturated fatty
acids in moderation.
