Accepted Answer

prolonged submersion leads to global hypoxia, water aspirated cause removal of surfactant and leads to pulmonary edema and hypoxia and death occurs.

Question 4

A man recovered from river and was shifted to hospital what is First initial task in management of submersion patient?&#10;A)insertion of nasogastric tube.&#10;B)Airways for Oxygen to relive hypoxia&#10;C)consideration for hypothermia&#10;D)correction of electrolyte imbalance.

Accepted Answer

According to ATLS guidelines airway securing is first initial task. the goal of therapy is to relive hypoxia, this mean to provide oxygenation and ventilation to the patient through mouth to mouth or through ventilation bag, Because hypoxia is cause of death.

Question 5

Accepted Answer

child severely asphyxiated , the vital organs start failure. acute respiratory distress syndrome ,cerebral edema, myocardial failure occurs. cerebral anoxia is early cause of death.

Question 9

In which of the following injury Majority of electrical flow occurs over the body?&#10;A)True electrical injuries&#10;B)Flash injuries&#10;C)Flame injuries&#10;D)Lightning injuries.

Accepted Answer

Lightning injuries is a unique type of injury that occurs at extremely high voltages for the shortest duration; the majority of electrical flow occurs over the body. true electrical injuries has electrical circuit and has an entrance and exit site ,Flash injuries - Superficial burns caused by arcs that burn the skin, Caused by ignition of the persons clothing by arc.

Question 10

In which electrical strike the person is part of the flash channel and Enormous quantities of energy pass through the body very quickly and this can result in internal burns and organ damage?&#10;A)Contact injury&#10;B)Side splash&#10;C)Direct strike&#10;D)Blast injuries

Accepted Answer

In direct injuries Enormous quantities of energy pass through the body very quickly and this can result in internal burns and organ damage. Contact injury - the person was touching an object, generally a conductor, that is electrified by the strike.
