NEET MDS Quiz - Practice Test

1

Medicine

In mitral stenosis, the radiological findings are all except
1. Double atrial shadow
2. Indentation of esophagus
3. Narrow airspace behind the sternum
4. Elevation of left bronchus

Option 1

Option 2

Option 3

Option 4

📝 Explanation:

Mitral Stenosis Radiological Findings

Double atrial shadow: This is a common finding in mitral stenosis due to left atrial enlargement.
Indentation of esophagus: The enlarged left atrium can compress the esophagus, leading to this finding.
Narrow airspace behind the sternum: This is not typically associated with mitral stenosis. Instead, it may indicate other conditions such as lung pathology.
Elevation of left bronchus: This can occur due to the enlarged left atrium pushing against the bronchus.

2

Medicine

A patient complains of two attacks of mild hemoptysis. Chest X-ray shows no pathology. The next investigation of choice is
1. MRI
2. HRCT
3. Bronchoscopy
4. Bronchography

Option 1

Option 2

Option 3

Option 4

📝 Explanation:

For a patient with hemoptysis and a normal chest X-ray, further investigation with a computed tomography (CT) scan is the recommended next step, especially for those with risk factors for malignancy (e.g., smokers, over 40 years old) or recurrent episodes.�

�The term HRCT (High-Resolution Computed Tomography) refers to a specific type of CT technique, and a contrast-enhanced chest CT or CT angiography is typically the preferred modality as it better identifies the cause and location of bleeding by visualizing both lung parenchyma/airways and the thoracic vessels.

3

Medicine

Craniospinal irradiation is useful in which of the following conditions?
1 Pilocytic astrocytoma
2 Oligodendroglioma
3 Medulloblastoma
4 Oncocytoma

Option 1

Option 2

Option 3

Option 4

📝 Explanation:

Medulloblastoma is a malignant brain tumor that commonly occurs in children. Due to its tendency to spread along the cerebrospinal fluid (CSF), craniospinal irradiation is an essential part of its treatment. Pilocytic astrocytomas and oligodendrogliomas typically do not require this approach.
