Which surgical procedure involves removing a portion of the lung?

  • A. Lobectomy
  • B. Pneumonectomy
  • C. Tracheostomy
  • D. Bronchoscopy
Correct Answer: A

Rationale: The correct answer is A: Lobectomy. A lobectomy involves the removal of a lobe of the lung. This procedure is commonly done to treat lung cancer or other conditions affecting a specific lobe. Pneumonectomy (B) involves the removal of an entire lung, not just a portion. Tracheostomy (C) is the surgical creation of an opening in the windpipe to help with breathing, not a lung removal procedure. Bronchoscopy (D) is a diagnostic procedure to visualize the airways using a flexible tube with a camera, not a lung removal surgery. Therefore, A is the correct choice for removing a portion of the lung.
