**Core Concept**
Pleural biopsy involves sampling tissue from the pleura, a thin membrane surrounding the lungs, for diagnostic purposes. This procedure requires a specific type of needle to obtain a representative tissue sample.
**Why the Correct Answer is Right**
The correct needle for pleural biopsy is the Abram's needle, which is a type of trocar needle. It consists of a sharp bevelled point and a side port for injecting local anesthesia and expanding the pleural space. The trocar is then withdrawn, leaving the needle in place, allowing for a biopsy sample to be obtained using a trocar or a smaller needle. This technique helps to minimize the risk of lung puncture and ensures a safe and effective biopsy.
**Why Each Wrong Option is Incorrect**
**Option A:** Could be incorrect because it's a generic term and doesn't specify the type of needle used for pleural biopsy.
**Option B:** May be incorrect as it could refer to a different type of needle used in other medical procedures.
**Option C:** Is incorrect because it's not a recognized needle type for pleural biopsy.
**Clinical Pearl / High-Yield Fact**
When performing a pleural biopsy, it's essential to use a large-gauge needle, such as the Abram's needle, to minimize the risk of lung puncture and ensure a safe and effective biopsy. This is a critical consideration in the diagnosis of conditions such as pleural effusions and lung cancer.
**Correct Answer: C. Abram's needle.**
