Which of the following is correct concerning the intracardiac mean pressures?
Right atrial pressure of 5 mmHg
Left atrial pressure of 8 mmHg
Mean pulmonary pressure of 40 mmHg
Left ventricular pressure of 120/80 mmHg
Aortic pressure of 70 mmHg
The following concerning the cardiac morphology is true except:
The heart is a muscular structure
The heart is a four-chambered organ
The heart receives four main venous returns
The great vessel of the heart consists of the aorta, the pulmonary artery, the superior vena cava, and the inferior vena cava
The heart receives four main venous returns (This option is likely redundant/incorrectly listed in the source)
The mostly likely diagnosis of a 16-year-old who presents with cyanosis and clubbing and easy fatigability is:
ASD (Atrial Septal Defect)
VSD (Ventricular Septal Defect)
TRUNCUS ARTERIOSUS
EISENMENGERS SYNDROME
COACTATION OF THE AORTA
The commonest cyanotic neonatal CHD is TGA (Transposition of the Great Arteries).
The commonest cyanotic childhood CHD is TOF (Tetralogy of Fallot).
The MOST useful investigation in suspected coarctation of the aorta is:
Cardiac catheterization
MR Angiography
ECG
CXR (Chest X-ray)
Echocardiography
Between the two membranes that surround the lung is a negative pressure space called:
The parietal space
The pleural space
The pericardial space
A 16-year-old presented to the accident and emergency with acute appendicitis. Further evaluation by the surgical resident noticed a 4/6 machinery murmur loudest at the pulmonic area of the precordium with bilateral fine crepitations. The most likely clinical diagnosis of the murmur is?
Atrial Septal Defect (ASD)
Ventricular Septal Defect (VSD)
Atrioventricular Septal Defect (AVSD)
Patent Ductus Arteriosus (PDA)
Tetralogy of Fallot (TOF)
The imaging of choice to confirm the cardiac condition before surgery of the acute abdomen will be?
CT Angiography (CTA)
Chest X-ray
Cardiac Catheterization
2-D Echocardiography
Electrocardiography
A 35-week term infant presents with cyanosis shortly after birth. His arterial oxygen saturation is only 30%. What is the most likely diagnosis?
Patent Ductus Arteriosus
Coarctation of the aorta
Atrial Septal Defect
Ventricular Septal defect
Transposition of the great arteries (TGA)
The most common congenital heart disease is:
Coarctation of the aorta
Patent Ductus Arteriosus
Atrial Septal Defect
Ventricular Septal Defect (VSD)
Pulmonary Stenosis
Which of the following statement is correct for the congenital cardiac anomaly called Atrial Septal Defect?
L→R shunt because of higher right intracardiac pressure
L→R shunt because of higher left intracardiac pressure
R→L shunt because of higher right intracardiac pressure
R→L shunt because of higher right intracardiac pressure
Cardiac output is increased
The commonest congenital heart disease is:
Coarctation of the aorta
Patent Ductus Arteriosus (PDA)
Atrial Septal Defect (ASD)
Ventricular Septal Defect (VSD)
The components of Tetralogy of Fallot include all the following except?
Obstruction to right ventricular outflow (Pulmonary Stenosis)
Ventricular Septal Defect (VSD)
Atrial Septal Defect (ASD)
Overriding Aorta
Hypertrophy of the Right Ventricle
A boot-shaped heart on plain chest x-ray in an infant is typical of?
Congenital Aortic stenosis
Atrial Septal Defect
Ventricular Septal Defect
Tetralogy of Fallot
Truncus Arteriosus
Which of the following has the greatest impact on the physiology of Tetralogy of Fallot?
The size of the ASD
The size of the VSD
The degree of pulmonary stenosis
The amount of aortic overriding
The overriding aorta
Which injuries are considered life-threatening/lethal injury requiring immediate intervention in a patient who presents with acute chest trauma?
Tension pneumothorax and cardiac tamponade
Cardiac contusion and rib fractures
Clavicle fracture and pulmonary contusion
Pneumomediastinum and subcutaneous emphysema
Sternal fracture and rib fracture
Flail chest is defined as:
Multiple rib fractures with subsequent subcutaneous emphysema
Chyle in the pleural space
Excess fluid in pericardium
Two or more ribs fractured at two points or segments
Abnormal accumulation of fluid in the mediastinal space
What is the most common medical intervention required for patients with thoracic trauma?
Chest tube insertion
Thoracotomy
VATS
Pericardiocentesis
A patient presented at a peripheral hospital with chest and neck pains following a fall from a height, which of the following chest injuries is one of the potentially life-threatening that might have sustained?
Open Pneumothorax
Massive Haemothorax
Cardiac Tamponade
Tension Pneumothorax
Esophageal injury
Which of the following chest injuries is lethal?
Myocardial Contusion
Sternal Fracture
Cardiac Tamponade
Tracheobronchial Injury
Acute Diaphragmatic Rupture
What is the purpose of the fluid in the pleural cavity?
Lubricate pleural surfaces for painless gliding
Warm and moisten lung tissue
Prevent bacteria entering lung tissue
Assist oxygen diffusion
A patient with an opening in the chest wall resulting in a “sucking chest wound” has:
An open pneumothorax
A closed pneumothorax
A hemothorax
A pleural effusion
