Ans: 2-D

Ottawa ankle guidelines are sensitive guidelines to decide about the need for X-ray, in a case of ankle sprain. Options A,B,C are the indications for X-ray as per the guidelines. All cases of ankle sprain do not require X-rays, as most are ligament injuries only.

Ans: 3- D

Worsening of pain on exposure to cold occurs in Raynaud’s disease. The increase in severity of neuropathic pain in carpal tunnel syndrome during night is attributed to night time posture of hand.

Ans: 4- A

Ans: 5- C

The vertebral mobility is more at C5-C6 level; hence the disc is most affected cervical spine disc.

Ans: 6-A

Erb’s palsy is caused by injury to C5-C6 nerve roots during difficult labour. The nerves most affected are suprascapular, musculocutaneous and axillary nerves. Deltoid, biceps and brachialis muscles are involved. The injury is due to traction and is always unilateral. The muscles of arm including deltoid are paralysed. Klumple’s palsy involves lower roots of brachial plaxus. Muscles of hand and forearm are affected. Both proximal myopathy and Duchenne muscular dystrophy have bilateral distribution.

Ans: 7- C

Ans: 8-A

The shoulder joint has great range of motion due to which it is particularly susceptible to dislocation. 95% of shoulder dislocations are anterior in location and may cause injury to axillary artery and axillary nerve.

Ans: 9-A

The giant cell tumor (GCT) appears on an X-ray as lytic lesions, described as soap bubble appearance. It is not surrounded by area of sclerosis. Most GCTs are benign, only 5% metastasize to lungs. They are epiphyseal in location and most commonly manifests as local pain.

Ans: 10-B

Baker’s cyst also known as popliteal cyst is found at the posterior aspect of knee, easily visualised when the patient is standing with knee extended. It is associated with knee arthritis or cartilage tear.
