![]() Paralysis of the affected muscles is a late sign of compartment syndrome. Of the choices, only bilateral compartment syndrome in the legs is consistent with the mechanism and presentation of this case. Transfer should be considered whenever the patient’s treatment needs exceed the capabilities of the institution. This decision requires an assessment of the patient’s injuries by the physician. ![]() Further diagnostic tests at this time would only delay the necessary surgical intervention, which is needed immediately. The patient is in hypovolemic shock from a gunshot wound in the abdomen. There is not enough time to obtain a chest xray. Needle thoracentesis should be done immediately. Associated signs would be absent breath sounds, hyperresonance, JVD, hypotension, and tracheal deviation. There is a high probability of a tension pneumothorax. The other answer choices are not the next priorities, and would delay resuscitation. Almost simultaneously, a pelvic binder should be applied and pressure applied to external hemorrhage sites; but, these are not provided as answer choices. ![]() Thus, a FAST scan or DPL should be performed quickly. In this scenario, airway and breathing have been addressed. ![]() Note: Up to a 30% diminution in circulating blood volume may be required to cause a decrease in the child’s systolic blood pressure. However, the percentage volume of blood loss required to produce shock is more than in adults. The absolute volume of blood loss required to produce shock is less than in adults. Most injured patients who are in hypovolemic shock require early surgical intervention or angioembolization, as well as fluid resuscitation. A spinal cord injury would generally cause absent reflexes at the level of the injury, hyperreflexia inferior to it, and normal reflexes superior to it. ![]() Short, largecaliber peripheral intravenous lines are preferred for the rapid infusion of large volumes of fluid. Treatment of frostbite should be immediate to decrease the duration of tissue freezing, although rewarming should not be undertaken if there is the risk of refreezing. The injured part should be placed in circulating water at a constant 40☌ (104☏) until pink color and perfusion return (usually within 20 to 30 minutes). This is best accomplished in a large tank, such as a whirlpool tank. Avoid dry heat since this risks burning the skin, and do not rub or massage the area since this causes more tissue injury. Rewarming can be extremely painful, and adequate analgesia is essential. Cardiac monitoring during rewarming is advised. ATLS Practice Test 1 Answers & ExplanationsĬ. ![]()
