Which of the following is not a function of the instrument given below ?
**Core Concept**
The instrument in question is likely a bronchoscope, which is a flexible or rigid tube used for visualizing the airways and collecting samples. The bronchoscope has multiple functions, including obtaining tissue samples, collecting secretions, and facilitating the administration of medication.
**Why the Correct Answer is Right**
The bronchoscope is equipped with channels for various functions. It has a biopsy channel for collecting tissue samples, a suction channel for removing secretions, and a working channel for administering medications or performing procedures like bronchial thermoplasty. The bronchoscope also has a camera and light source for visualizing the airways.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is likely a function of the bronchoscope, as it involves obtaining tissue samples for histopathological examination.
* **Option B:** This option is also a function of the bronchoscope, as it involves removing secretions from the airways.
* **Option C:** This option is not a function of the bronchoscope, as it involves performing a surgical procedure that requires a different type of instrument, such as a thoracoscope or a laparoscope.
**Clinical Pearl / High-Yield Fact**
It's essential to distinguish between the functions of different endoscopic instruments, such as bronchoscopes, gastrosopes, and colonoscopes, to ensure that the correct instrument is used for each procedure.
**Correct Answer:** C. This option is not a function of the bronchoscope.
