A 17) B

Capsule endoscopy has a sensitivity of detecting occult GI bleed in 60-70% cases. Its advantages are that it is painless and easy to do in centers that have the technology to do it. No sedation is required and it visualizes the whole bowel. It is painless and preferable.

Its disadvantages are that it is not accurate and does not accurately tells the bleeding point. Can not be done in strictures and those who can not swallow. Sometimes the batteries dies and studies are  incomplete

Leg Compartments
                                       Compartments of leg

The bones in the lower leg, interosseous membranes, and fascia divide the lower leg into four compartments.

Anterior compartment: between the deep fascia and the interosseous membrane, with the
tibia medially and the fibula laterally.It has  the deep peroneal nerve and the anterior tibial vessels.

Lateral compartment: lies between the deep fascia, peroneal surface of the fibula and the
anterior and posterior intermuscular septa.  superficial peroneal nerve.

The posterior compartment is divided into deep and superficial compartments. The deep
posterior compartment contains  tibial nerve.

The superficial posterior compartment contains and the medial sural cutaneous nerve.

19 ) d. 


Penetrating injury to the abdomen with shock, patient should be taken directly for the laparotomy. In case of penetrating injury abdomen, with shock, peritonitis and evisceration, patient should be taken for laparotomy.

Otherwise patient should go for local wound exploration, and serial physical examination. If there is hemodynamic instability, patient should then go for exploration.

CT or DPL should be considered in case of significant decrease in hemoglobin (<3g/dl)  or leukocytosis.

20 ) a

In hemodynamically stable children with isolated liver injury, conservative management should be done. Isolated liver injury means only parenchymal injury without involving hepatic vein, IVC, portal vein or hepatic artery.

Intervention should be done if there is hemodynamic instability, deteriorating clinical findings, blood requirement of 40ml/kg/day

In well equipped centres, angiography and embolisation of bleeding vessels can be done  otherwise surgery is the standard of care.
