Q

Describe the difference between direct and indirect inguinal hernias.

A

Direct inguinal hernia protrudes directly through the superficial ring, while indirect hernia first enters the deep ring before protruding through the superficial ring.

Q

A 28-year-old man is shot in the right chest and develops a right haemothorax necessitating a thoracotomy. The surgeons decided to place a vascular clamp across the hilum of the right lung. Which structures will lie most anteriorly at this point?

Q

A 67-year-old gentleman presents to the Emergency Department with acute central chest pain that is sharp and stabbing in nature. The pain radiates to the back, neck, and left shoulder. The pain is relieved by sitting forward and worsened by lying down, and he feels feverish. He tells you that he had a recent hospital admission for a heart attack three weeks ago. Upon auscultation at the left sternal border, you can hear a scratchy sound while the patient leans forward and holds his breath. His ECG shows widespread ST-segment saddle elevation and PR-segment depression.

What nerve is the cause of this shoulder pain?

A

Phrenic nerve - supplies the pericardium

Q

A 72-year-old man with carcinoma of the lung is undergoing a left pneumonectomy. The left main bronchus is divided. Which thoracic vertebrae lies posterior to this structure?

A

T6

17
Q

C3-C6 corresponds to what?

A

Larynx

18
Q

T12-L1 corresponds to what?

A

Duodenum

19
Q

A 5-year-old boy is playing with some small ball bearings. Unfortunately he inhales one. To which of the following lung regions is the ball most likely to settle?

A

Right Lower/middle Lobe

20
Q

The space between the vocal cords is referred to as what?

A

Rima glottidis

21
Q

A man is stabbed in the chest to the right of the manubriosternal angle. Which structure is least likely to be injured in this case?

A

Right Recurrent laryngeal nerve

22
Q

Long thoracic nerve is susceptible to damage during what?

A

Chest Drain insertion

23
Q

Can you differentiate between a direct and an indirect inguinal hernia?

A

Yes, to differentiate between the two, reduce the hernia, occlude the deep ring with the fingertip, and ask the patient to cough. If it is a direct hernia, the lump will reappear, as it does not need to pass through the deep ring to get out into the scrotum

24
Q

What is the consequence of paralysis of the long thoracic nerve?

A

A winged scapula

25
Q

What nerve supplies the serratus anterior muscle?

A

The long thoracic nerve

26
Q

What is the mnemonic for remembering the openings in the diaphragm?

A

The mnemonic is “I Ate 10 Eggs At 12” (Inferior vena cava pierces at T8, Oesophagus pierces at T10, Aorta pierces at T12)

27
Q

What is the order of the intercostal neurovascular bundles from superior to inferior?

A

The order is vein, artery, then nerve (VAN)

28
Q

What is the arterial supply and venous drainage of the intercostal spaces?

A

Anterior intercostal arteries branch from the internal thoracic artery and anterior intercostal veins drain into internal thoracic veins

While posterior intercostal arteries branch from the thoracic aorta, and posterior intercostal veins drain into the azygous vein

29
Q

What is the structure that marks the boundary between the thorax and abdomen?

A

The diaphragm marks the boundary between the thorax and abdomen

30
Q

What is the primary muscle responsible for respiration at rest?

A

The diaphragm

31
Q

The liver lies deep to what ribs?

A

7-11

32
Q

Where does azygous vein drain into?

A

SVC

33
Q

A 17-year-old female presents to the emergency department with wheezing, coughing, and shortness of breath. The patient has a history of bronchospasm caused by exercise-induced asthma. Which nerve(s) should the physician block to treat the patient’s bronchospasm?

A

Vagus nerve

34
Q

A 65-year-old man is taken to the emergency department by his wife after collapsing while shovelling snow. The patient reports a crushing chest pain that he has never felt before, as well as left arm and jaw pain. His wife reports that he has had chest pain in the past that occurs with exertion and is relieved with rest, and he has a past medical history of hypertension, hyperlipidemia, and smoking. The emergency room provider orders an angiogram for further assessment.

If there were a gradual narrowing of the right coronary artery, a direct anastomosis with which other arteries would allow retrograde flow to develop?

A

Left circumference artery

35
Q

Asian man with night sweats, fever and weight loss?

A

TB

36
Q

Biliary tract infection treatment

A

Ciprofloxacin or gentamicin or a cephalosporin

37
Q

Posterior intercostal spaces

A

thoracic aorta/azygous vein

38
Q

Anterior intercostal spaces

A

internal thoracic artery/vein
