Nremt advanced emt practice test pdf1/9/2023 It would increase intracerebral bleeding in patients with hemorrhagic stroke therefore, fibrinolytic therapy is contraindicated for these patients. Because fibrinolytic therapy decreases the blood's ability to clot, its use is limited to patients with ischemic strokes. In addition to providing supplemental oxygen, transport the patient without delay so that she may receive fibrinolytic therapy (if she is a candidate) at the hospital. It is critical to ask a family member or bystander when the patient was last seen normal. Reason:Fibrinolytic (clot-buster) therapy is critical to a patient who is having a stroke if it is initiated within 3 hours after the onset of symptoms. D:administer high-flow oxygen via a nonrebreathing mask, apply a chemical cold pack to the sting, transport at once, and be prepared to administer the epinephrine from his bee sting kit.C:assist his ventilations with a bag-mask device, administer epinephrine from his bee sting kit after receiving approval from medical control, and prepare for immediate transport.B:provide positive-pressure ventilations, initiate rapid transport, and coordinate a rendezvous with a paramedic unit so they can administer the epinephrine from his bee sting kit.A:give him high-flow oxygen via a nonrebreathing mask, cover him with a blanket and elevate his legs, and assist him in swallowing the antihistamine tablets that are in his bee sting kit.The patient has a bee sting kit, but has not used it. When you arrive at the scene, you note that his level of consciousness is decreased, his breathing is labored, and wheezing can be heard without a stethoscope. Abdominal thrusts are used to remove a solid foreign body from the airway, not liquid.Īpproximately 5 minutes after being stung by a bee, a 21-year-old male develops hives and begins experiencing difficulty breathing. Manual gastric decompression should ONLY be performed if gastric distention is so severe that it is impossible to ventilate a patient AND a paramedic is not present to insert a gastric tube into the stomach. Manual gastric decompression, which involves applying pressure to the patient's abdomen, is a dangerous maneuver because it will force more water from the stomach, which the patient could potentially aspirate. You should turn the patient onto his side to facilitate drainage of liquid, but do not apply pressure to his abdomen. This alternating sequence should be repeated until all secretions are cleared from the airway. This is accomplished most effectively by suctioning for 15 seconds and then ventilating for 2 minutes. ![]() Reason:In cases where a patient is not breathing and is regurgitating (passively vomiting) secretions at the same time, you must address both issues. Its symptoms include nausea, vomiting, headache, weakness, paralysis, and possibly cardiopulmonary failure. Rocky Mountain spotted fever, which is not limited to the Rocky Mountains, occurs within 7 to 10 days after being bitten by an infected tick. If recognized and treated promptly with antibiotics, many patients recover completely. After a few more days or weeks, painful swelling of the joints, particularly the knees, occurs. ![]() The rash may eventually resemble a target bull's-eye pattern in one third of patients. The first symptom of Lyme disease, a rash that may spread to several parts of the body, begins about 3 days after the bite of an infected tick. Both are spread through the tick's saliva, which is injected into the skin when the tick attaches itself. Ticks can carry two infectious diseases: Lyme disease and Rocky Mountain spotted fever. Reason:The patient's symptoms and her history of a recent hiking trip are consistent with Lyme disease, which was the result of a tick bite. The most obvious way to decrease heat loss by conduction is to remove your hand from the cold object. Conduction is the direct transfer of heat from a part of the body to a colder object by direct contact, as when a warm hand touches cold metal or ice. Layers of clothing trap air and provide excellent insulation thus, layered clothing decreases heat loss better than a single, thick jacket. Shivering increases the body's metabolism and is a mechanism for generating heat, not reducing heat loss. The quickest and most obvious way to decrease heat loss from radiation and convection is to move out of the cold environment and seek shelter from wind. A person standing in windy cold weather, wearing lightweight clothing, is losing heat to the environment mostly by convection. Convection occurs when heat is transferred to circulating air, as when cool air moves across the body's surface. The body can lose heat by radiation, such as when a person stands in a cold room. ![]() Radiation is the transfer of heat by radiant energy. Reason:In a cold environment, the body has two ways of staying warm: generating heat (thermogenesis) and reducing heat loss.
