Heat loss from the body through respiration occurs when:, warm air in the lungs is exhaled into the atmosphere., cool air is inhaled and displaces warm air., In contrast to Lyme disease, Rocky Mountain spotted fever:, can cause paralysis and cardiorespiratory collapse., presents with flu-like symptoms and a bull’s-eye rash., Most of the serious injuries associated with scuba diving are caused by:, too rapid descent, too rapid ascent, alcohol consumption, Signs and symptoms of an air embolism include all of the following, _except_:, dysphasia, pale skin, dizziness, joint pain, Patients with generalized hypothermia are at an increased risk of a local cold injury because:, peripheral vasodilation brings warm blood to the skin’s surface., the patient is usually unable to escape the cold ambient temperature., blood is shunted away from the extremities to the body’s core., Rough handling of a hypothermic patient with a pulse might cause:, profound bradycardia., ventricular fibrillation., ventricular tachycardia., pulseless electrical activity., Shivering is a mechanism in which the body generates heat by:, increasing the metabolic rate., decreasing the use of oxygen., The EMT must assume that any unwitnessed water-related incident is accompanied by:, an air embolism., alcohol intoxication., possible spinal injury., cold-water immersion., The venom of a brown recluse spider is cytotoxic, meaning that it:, suppresses the respiratory drive., weakens the structure of the bones., causes severe local tissue damage., To assess a patient’s general body temperature, pull back on your glove and place the back of your hand on their skin at the:, neck, abdomen, forehead, What is the correct emergency treatment for a coelenterate (jellyfish) sting?, Avoid fresh water, remove tentacles with a stiff object, apply vinegar., Wash with soap and water, apply alcohol, resume activity., When the body loses sweat, it also loses:, fat, plasma, electrolytes, Which of the following is the _most_ serious consequence of mild hypothermia?, foot stomping, constricted blood vessels, severe muscular rigidity, blood clotting abnormalities, You and your partner are standing by at a large social event at a river resort when a frantic woman tells you that she found a young male floating face-down in the water. Nobody claims to have witnessed the event. After you and your partner enter the water and reach the patient, you should:, move him as a unit to a supine position., begin ventilations with a barrier device., immediately secure him to a longboard., open his airway with the jaw-thrust maneuver, You are assessing a 32-year-old male who complains of severe abdominal pain, weakness, and nausea. He tells you that he was gathering wood to build a fire when he felt a sudden, sharp pain on the back of his hand. Your assessment reveals that the patient’s abdomen is rigid and painful to palpation. You should suspect:, a black widow spider bite., envenomation from a pit viper., a brown recluse spider bite., Rocky Mountain spotted fever., You are assessing a man with suspected hypothermia. The patient is conscious, alert, and actively shivering. His respiratory rate is increased, but his breathing is unlabored, and the pulse oximeter reads 72%. The pulse oximetry reading is _most_ likely:, secondary to decreased perfusion in the extremities., accurate because he has signs of respiratory failure, You are dispatched to a local high school track and field event for a 16-year-old male who fainted. The outside temperature is approximately 95°F (35°C) with high humidity. Upon your arrival, the patient is conscious, alert, and complains of nausea and a headache. His skin is cool, clammy, and pale. You should:, give him a liquid salt solution to drink., administer 100% supplemental oxygen., move him into the cooled ambulance., You are dispatched to a residence for a young female who is sick. The patient complains of a rash to her lower extremities and truncal area. Your assessment reveals a small, painful blister on her inner thigh. As your partner is taking the patient’s vital signs, she states that she and her family returned from a camping trip two days ago. On the basis of this patient’s presentation, you should suspect:, Rocky Mountain spotted fever., Lyme disease., You respond to a call at an abandoned building where a 25-year-old male has been bitten by a copperhead snake.

On assessment, you note that he has cyanosis around his lips and pink froth coming from his nose and mouth. You should:, apply high-flow oxygen, monitor the patient’s breath sounds for a pneumothorax, and contact medical control regarding transport to a recompression facility., suction his mouth and nose, keep him supine and elevate his legs to prevent air bubbles from entering his brain, administer high-flow oxygen, and transport to a hyperbaric chamber., Your assessment of a 23-year-old female reveals a core body temperature of 93.4°F (34°C). She is conscious, answers your questions appropriately, is shivering, and complains of nausea. Her skin is cold and pale, her muscles appear rigid, and her respirations are rapid. You should:, cover her with warm blankets and let her move about on the stretcher to generate body heat and increase her temperature., place heat packs to her groin, axillae, and behind her neck; cover her with warm blankets; and avoid rough handling.
