SZABMU MD Part-I Paper II MCQs: Cardiovascular, Respiratory & Gastroenterology

Cardiovascular, respiratory and gastroenterology are 10% each of SZABMU MD Part-I Paper II, so 30 marks between them. The questions are short clinical vignettes asking for a diagnosis, the next test or the best treatment. Here is a sample from our MD bank.

Sample MCQs

1. Endocardial cushion defects lead to which of the following defects?

• A) Tetralogy of Fallot
• B) AVSD ✅
• C) ASD
• D) VSD

Failure of endocardial cushion fusion results in atrioventricular septal defects, with ostium primum ASD and VSD.

2. A 9-year-old with a boot-shaped heart on X-ray:

• A) Turner's
• B) ASD
• C) TOF ✅
• D) TGA

A boot-shaped heart (coeur en sabot) is the classic X-ray appearance of tetralogy of Fallot.

3. A wide QRS complex of more than 120 ms is seen in:

• A) LBBB ✅
• B) Atrial tachycardia
• C) AVNRT
• D) AVRT

Bundle branch block widens the QRS beyond 120 ms; supraventricular tachycardias usually have a narrow QRS.

4. A 35-year-old man presents in a clinic with history of chronic productive cough that is worse in the morning and brought on by changes in posture. Sputum is copious and yellow. The most likely diagnosis in this patient is:

• A) Bronchiectasis ✅
• B) Bronchogenic carcinoma
• C) Chronic bronchitis
• D) Bronchial asthma

A cough with copious purulent sputum on postural change is characteristic of bronchiectasis.

5. Stridor in a vaccinated 5-year-old child is likely because of which of the following?

• A) Epiglottitis
• B) Laryngotracheal malacia
• C) Bacterial pneumonia
• D) Viral croup ✅

Croup (laryngotracheobronchitis) from parainfluenza virus is the commonest cause of stridor in children, while epiglottitis is rare after HiB vaccination.

6. A man presents to the clinic with new-onset haemoptysis. He had TB that was treated 5 years ago. He currently has no fever and no weight loss and only an occasional cough that was recently blood streaked. What could be the cause?

• A) Small cell lung carcinoma
• B) Bronchogenic carcinoma
• C) Reinfection with TB
• D) Aspergilloma ✅

A fungus ball colonising an old tuberculous cavity (aspergilloma) causes recurrent haemoptysis without constitutional symptoms.

7. A patient with gluten intolerance has crops of small fluid-filled painful blisters that come and go. She is worried that she might have herpes. What is your diagnosis?

• A) Guttate psoriasis
• B) Eczema
• C) Dermatitis herpetiformis ✅
• D) Herpetic whitlow

Itchy grouped vesicles in a patient with coeliac disease are dermatitis herpetiformis.

8. A consultant orders carcinoembryonic antigen (CEA). What is he checking for?

• A) Multiple sclerosis
• B) Pancreatitis
• C) Colorectal carcinoma ✅
• D) Sarcoidosis

CEA is the tumour marker used for monitoring and recurrence of colorectal carcinoma.

9. A patient presents with a history of 1 year of steatorrhoea, vitamin D deficiency and weight loss. He has a pancreatic head mass on CT scan. What would you give him for his steatorrhoea?

• A) Multivitamin tablet
• B) Creon therapy adjusted to weight ✅
• C) Vitamins D, A, K and E supplementation
• D) Vitamin D supplements

Pancreatic enzyme replacement (Creon) is the treatment of steatorrhoea due to exocrine pancreatic insufficiency.

How These Questions Are Built

Most give two or three clues and ask you to name the condition; the options are usually from the same category. Read the final line of the stem first, then the clues. Work the topic sets in the Cardiovascular, Respiratory and Gastroenterology sections.

Practise With Explanations

The SZABMU MD QBank groups its MCQs by the official Paper I and Paper II topics, with an explanation for every question and topic analytics to show where marks are leaking. The first 20 questions are free, and the mock tests come included with the QBank. The MS bank shares the same Paper I core and swaps Paper II for applied surgery.
