![]() ![]() 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. #National registry emt practice test pdf skinBoth 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. ![]()
