What are the answers to questions 16, 17, and 18 regarding lung cancer and pulmonary rehabilitation?

Here are the answers to your questions:

16. Which of the following is the most common type of lung cancer? The correct option is:

• Non-small cell lung cancer (NSCLC)

Explanation: Non-small cell lung cancer (NSCLC) is the most common type of lung cancer, accounting for approximately 85% of all lung cancer cases. Adenocarcinoma is a subtype of NSCLC, and while it is the most common subtype, NSCLC is the broader, most common type. Small cell lung cancer makes up about 10-15% of cases, and sarcoma is a very rare type of cancer that can affect the lungs but is not typically classified as a primary lung cancer type.

17. What is the primary screening method for lung cancer? The correct option is:

• Chest X-ray and CT scan

Explanation: The primary screening method recommended for high-risk individuals for lung cancer is a low-dose computed tomography (CT) scan. While a chest X-ray can sometimes show abnormalities, it is not sensitive enough for effective screening on its own. MRI scans are not typically used for primary screening. Blood culture is used to detect infections, and spirometry measures lung function, neither of which are primary screening methods for lung cancer.

18. Which of the following professionals is NOT typically part of a pulmonary rehabilitation team? The correct option is:

• Surgeon

Explanation: Pulmonary rehabilitation is a multidisciplinary program. A physiotherapist (or physical therapist) is essential for exercise training, and a nutritionist provides vital dietary guidance. A surgeon performs surgical procedures and is involved in the treatment of lung diseases, but they are not typically a direct, ongoing member of the pulmonary rehabilitation team, which focuses on non-surgical interventions to improve patient function and quality of life.
