In DIC, which is/are seen-
**Core Concept**
Disseminated Intravascular Coagulation (DIC) is a complex condition characterized by both widespread clotting and bleeding in the vascular system, resulting from an imbalance in the coagulation and anticoagulation pathways. This imbalance leads to the formation of numerous small thrombi in the blood vessels, consuming platelets and coagulation factors.
**Why the Correct Answer is Right**
The correct answer choice would typically include findings such as prolonged prothrombin time (PT), partial thromboplastin time (PTT), decreased fibrinogen levels, and thrombocytopenia, as these are direct consequences of the consumption of coagulation factors and platelets in the formation of thrombi throughout the body.
**Why Each Wrong Option is Incorrect**
**Option A:** Would be incorrect if it suggested normal coagulation parameters, as DIC is characterized by abnormalities in these tests.
**Option B:** Might be incorrect if it implied that only bleeding or only clotting was a feature, as DIC involves both.
**Option C:** Could be incorrect if it suggested that DIC does not affect platelet count or coagulation factor levels.
**Option D:** Might be wrong if it did not include any of the typical laboratory findings associated with DIC.
**Clinical Pearl / High-Yield Fact**
A key point to remember is that DIC is a diagnosis based on a combination of clinical and laboratory findings, including a predisposing condition (like sepsis, trauma, or cancer), laboratory evidence of coagulopathy, and organ dysfunction.
**Correct Answer:** Correct Answer: D. Prolonged PT, PTT, low fibrinogen, thrombocytopenia.
