Q21If a patient has suffered from smoke inhalation in a fire, they should be transported to a hospital that has what type of specialized facility?
✓ Correct answer: D. A hyperbaric chamber
Answer: A hyperbaric chamber A hyperbaric chamber involves breathing pure oxygen in a pressurized environment. The increased air pressure allows the lungs to absorb more oxygen, which helps in healing tissues damaged by smoke inhalation. Hyperbaric chambers are also used to eliminate carbon monoxide and other toxins from the bloodstream. An MRI machine, an ultrasound machine, and a pressure mattress are not specifically required for smoke inhalation treatment.
Q22When approaching a moving vehicle accident scene as an EMR, it's critical to assess and control multiple hazards. What is the typical speed (in mph) of traffic passing by an accident scene on a highway?
✓ Correct answer: C. 60 to 70 miles per hour (mph)
Answer: 60 to 70 miles per hour (mph) Traffic passing an accident scene on a highway typically travels between 60 to 70 miles per hour. It is crucial for EMRs to be aware of these speeds to effectively manage the scene and ensure safety. Speeds lower than 40 mph or as high as 80 mph are uncommon and can be misleading in such scenarios.
Q23You arrive at the scene of a building collapse with multiple victims trapped inside. A specialized rescue team is en route. The structure appears unstable, and initial reports suggest there are eight victims. Law enforcement is managing crowd control. You determine the scene is safe for your initial assessment and call for additional support. What are EMRs' two primary goals when conducting a rescue operation in this scenario?
✓ Correct answer: B. To obtain safe access to each victim and to ensure each victim is stabilized
Answer: To obtain safe access to each victim and to ensure each victim is stabilized. The two primary goals in a rescue operation for an EMR are to gain safe access to each victim and to ensure that each victim is stabilized. If these objectives are achieved, you can then proceed to treat and stabilize the trapped victims. Making sure the scene is safe to enter is the first priority for an EMR, but it is not part of the primary goals in rescue operations. Stabilizing the structure might be a necessary step, but it is not among the primary goals. Determining the number of victims occurs during the scene size-up and is not one of the two primary goals of the rescue operation.
Q24During a large-scale wildfire affecting a residential area, multiple casualties are reported. There are 25 ambulatory patients, 60 deceased, 50 in critical condition, and 45 with serious but stable injuries. Firefighters and police officers are actively engaged in containment and rescue operations, with additional help on the way. Whom should you assign the task of helping to calm and reassure patients who are in shock?
✓ Correct answer: D. Ambulatory patients
Answer: Ambulatory patients In a mass casualty incident, ambulatory patients, also known as walking-wounded, can be enlisted to help calm and reassure other patients, including those in shock. These individuals are physically capable of moving around and providing basic emotional support. Critical condition and serious but stable patients are not suitable for this task due to their medical needs. Police officers are typically involved in safety and security operations and are not available for patient care tasks during such incidents.
Q25Which of the following is not considered a major type of bleeding?
✓ Correct answer: C. Internal bleeding
Correct answer: Internal bleeding Internal bleeding is not one of the three major categories of bleeding encountered in trauma situations. The three major types of bleeding are arterial, venous, and capillary bleeding, which differ based on the type of blood vessel affected and the severity of the bleed. Arterial bleeding involves high pressure and bright red blood spurting with each heartbeat. Venous bleeding is characterized by a steady flow of dark red blood. Capillary bleeding, the least severe, results in a slow, oozing flow from the smallest blood vessels.
Q26How should an Emergency Medical Responder (EMR) manage an impaled object in a patient's cheek?
✓ Correct answer: B. Stabilize the object with bulky dressings and ensure both the inside and outside of the cheek are supported.
Answer: Stabilize the object with bulky dressings and ensure both the inside and outside of the cheek are supported. When a patient has an impaled object in their cheek, the preferred method is to stabilize the object with bulky dressings. Make sure to support both the inside and outside of the cheek to prevent movement. Removing the object can cause more damage and increase bleeding, so it is only done by advanced medical personnel. A paper cup is not appropriate for this scenario, and having the patient bite down on a gauze pad can cause unintended movement of the object. Stabilizing the object with bulky dressings helps to prevent further injury and controls bleeding by immobilizing the object in place.
Q27A hiker has sustained an apparent dislocation of the shoulder after a fall. To immobilize the injured shoulder, you need to use a swathe. What is the term for the triangular swathe of cloth used for this purpose?
✓ Correct answer: C. A cravat
Answer: A cravat. A cravat is a term for the triangular swathe of cloth used to hold an injured limb against the body, which is often made from a triangular bandage. Cravats can also be used as slings and to hold bandages in place.
Q28A 25-year-old construction worker sustained a hand injury while using a power tool. Upon arrival, you notice that a section of the worker's skin and underlying tissue has been forcibly separated from the hand, but is still attached by a small piece of skin. What is this type of injury called?
✓ Correct answer: A. An avulsion
Answer: An avulsion. An avulsion is a type of injury where body tissue is forcibly torn away, either completely or partially, with a portion remaining attached by a flap of skin. An amputation involves the complete removal of a limb or other body part. An abrasion occurs when the skin is scraped off, typically by friction with a rough surface. A laceration refers to a deep cut or tear in the skin or flesh.
Q29You are called to a local pond where a 6-month-old infant has reportedly been submerged underwater for a few minutes. Upon arrival, the infant is unresponsive and not breathing. How should an Emergency Medical Responder determine the infant's level of responsiveness?
✓ Correct answer: B. By gently shaking or tapping the infant
Answer: By gently shaking or tapping the infant To determine an infant's level of responsiveness, an Emergency Medical Responder should gently shake or tap the infant. Typically, an unresponsive infant will be limp and unresponsive to such actions. Once unresponsiveness is confirmed, the responder should check the brachial pulse and signs of breathing. If the infant has a complete airway obstruction, give five back slaps followed by five chest thrusts. Note that these actions are for airway management, not assessing responsiveness. Healthcare professionals do not use spanking to assess an infant's responsiveness. Instead, they may use techniques such as drying the infant vigorously with a clean towel to encourage crying and breathing in newborns.
Q30Certain severe injuries indicate that CPR should not be initiated, such as transection. What is transection?
✓ Correct answer: C. The body is severed into two parts at the torso.
Answer: The body is severed into two parts at the torso. Transection occurs when the body is completely severed into two parts at the torso. When a patient is transected, it is an obvious sign of death, and CPR will not be performed. Transection can occur in vehicle and motorcycle accidents, train accidents, industrial accidents, or other traumatic events. Transection is not the term used if arms, legs, or the head are severed from the body. If limbs such as arms or legs are severed, it is called amputation, and if the head is severed, it is known as decapitation.
