Sample Lungs and Pleura MCQs with answers
Sample MCQ #1
Which of the following does NOT characterize atresia of the valve of the pulmonary artery:
AA patent foramen ovale is the only outlet for blood from the right side of the heart
BThe right ventricle is markedly underdeveloped
CA patent ductus arteriosus offers a route of blood flow to the lungs
DThere is an overriding aorta
Show Answer & Explanation ▾
✓ Correct Answer: D. There is an overriding aorta
When the pulmonary valve is atretic, the only way for blood to get out of the right side is via a patent foramen ovale. Conversely, the only way for blood to get to the lungs is via the patent ductus arteriosus. Because the right ventricle is not pumping blood, it becomes markedly hypoplastic. There is no overriding aorta. Reference - Textbook of Langman's, 12th Edition, Cardiovascular System Embryology Page number - 185
Sample MCQ #2
Which is the most superior structure at the hilum of the left lung?
APulmonary veins
BBronchial artery
CBronchus
DPulmonary artery
Show Answer & Explanation ▾
✓ Correct Answer: D. Pulmonary artery
The sequence of structures at the left hilum superior to inferior is: (Mnemonic: 'ABV') Pulmonary artery, Principal (hyparterial) bronchus Inferior pulmonary vein The sequence of structures at the right hilum superior to inferior is: (Mnemonic : 'BABV') Superior lobar (eparterial) bronchus Pulmonary artery Principal bronchus Inferior pulmonary vein Reference: Textbook of Gray's Anatomy for students, 3rd Edition, Thorax, Page number - 167
Sample MCQ #3
What is the inferior most structure of the right hilum?
ARight atrium
BInferior pulmonary vein
CPulmonary artery
DInferior bronchial vein
Show Answer & Explanation ▾
✓ Correct Answer: B. Inferior pulmonary vein
The inferior most structure of the right hilum is the inferior pulmonary vein. The sequence of structures at the right hilum superior to inferior is: (Mnemonic - 'BABV') Superior lobar (eparterial) bronchus Pulmonary artery Principal bronchus Inferior pulmonary vein Reference: Textbook of Gray's Anatomy for students, 3rd Edition, Thorax, Page number - 163
Sample MCQ #4
Which of the following is a posterior relation to the root of the right lung?
ARight atrium
BRight vagus nerve
CSuperior vena cava
DPhrenic nerve
Show Answer & Explanation ▾
✓ Correct Answer: B. Right vagus nerve
The vagus nerve is posterior to the root of the lung- The roots of the lung are at the level of T5-17 vertebral bodies. The phrenic nerve is anterior to the root of the lung. Reference: Textbook of Gray's Anatomy for students, 3rd Edition, Thorax, Page number - 167
Sample MCQ #5
A 50-year-old woman presented with chest pain, dyspnea, and weight loss. Chest X-ray showed an elevated right dome of the diaphragm. CT revealed a tumor invading the right lung surface anterior to the hilum. Which of the following nerves is most likely to be involved by the tumor?
ARecurrent laryngeal nerve
BIntercostal nerve
CVagus nerve
DPhrenic nerve
Show Answer & Explanation ▾
✓ Correct Answer: D. Phrenic nerve
The right phrenic nerve is involved by the tumor as it passes anterior to the hilum of the lung. The phrenic nerve provides the sole motor supply to the diaphragm. Normally, the diaphragm flattens when it contracts. Involvement of the phrenic nerve causes elevation of the respective dome of the diaphragm.

Sample MCQ #6
A patient was stabbed 23 times. One such stab wound was present in the left supraclavicular fossa, piercing his left lung. Which of the following provides the vertebral attachment to the fascia present here?
AC5
BC6
CC7
DC8
Show Answer & Explanation ▾
✓ Correct Answer: C. C7
The stab injury penetrated the apex of the lung. It is covered by Sibson's fascia, also known as the suprapleural membrane. Attachment of Sibson's fascia is at vertebra C7. Reference: Textbook of Gray's Anatomy for students, 3rd Edition, Thorax, Page number - 180
Sample MCQ #7
Which among the following is incorrect regarding Sibsons's fascia?
AAttached to the inner border of 2nd rib
BCovers apical part of lung
CPart of scalenus minimus muscle
DVessels pass above the fascia
Show Answer & Explanation ▾
✓ Correct Answer: A. Attached to the inner border of 2nd rib
Sibson's fascia is attached to the inner border of the 1st rib, not the 2nd rib. Sibson's fascia (suprapleural membrane) serves as a plane of separation between the lower neck and the thorax and covers the apical part of the lung. It is attached to the inner border of the 1st rib and posteriorly to the anterior border of the transverse process of the C7 vertebra.

Sample MCQ #8
Which statement is true about the right lung?
AIt is slightly smaller than the left lung
BIt has a lingular segmental bronchus
CIt occupies the rightmost portion of the mediastinum
DIts upper lobar bronchus lies behind and above the right pulmonary artery
Show Answer & Explanation ▾
✓ Correct Answer: D. Its upper lobar bronchus lies behind and above the right pulmonary artery
The structures at the root of the lung have different relationships in the right and left lungs. On both sides, the pulmonary veins are anterior and inferior while the bronchus is posterior. The difference between the two sides involves the pulmonary arteries. On the right side, the arteries are anterior to the bronchus, while on the left side the arteries are superior to the bronchus. The right lung is slightly larger than the left lung, and the lingula is found in the left lung only. Neither lung is in the mediastinum--the mediastinum is the space between the two pleural sacs. Finally, the phrenic nerve passes anterior to the root of the lung--on both the left and right sides. Reference: Textbook of Gray's Anatomy for students, 3rd Edition, Thorax, Page number - 128
