Paramedic Quiz Chapter 21 And 22

If the patient is breathing shallowly and access to the airway is difficult, the motorcycle or football helmet should be removed. This is because in such a situation, it is crucial to ensure that the patient's airway is clear and unobstructed to facilitate proper breathing. The helmet may impede access to the airway and hinder the ability to provide necessary medical assistance. Therefore, removing the helmet becomes a priority to ensure the patient's safety and well-being.

The primary risk associated with oral and dental injuries is airway compromise. This means that an injury to the mouth or teeth can potentially obstruct the airway, making it difficult for the person to breathe. This can be a life-threatening situation and requires immediate medical attention. Malocclusion refers to misalignment of the teeth, intraoral infection refers to infection within the mouth, and permanent tooth loss refers to the loss of a tooth, but none of these pose as immediate risks to the airway.

In cases of serious anterior neck trauma and inadequate breathing in an unresponsive patient, the priority is to secure manual in-line stabilization of the cervical spine to prevent any further damage. This is followed by assisting ventilations with a bag-valve-mask (BVM) to ensure adequate oxygenation. Finally, the healthcare provider should prepare to intubate the patient if necessary to establish a secure airway. This approach ensures the safety of the patient's spine while addressing their breathing difficulties.

Primary spinal cord injury occurs at the moment of impact. This means that the initial damage to the spinal cord happens immediately when the injury occurs. Unlike secondary spinal cord injury, which can occur after the initial trauma due to progressive swelling or other factors, primary spinal cord injury is the direct result of the impact itself.

When moving an injured patient from the ground onto a long backboard, it is generally preferred to use the four person log roll technique. This technique involves four individuals working together to gently roll the patient onto the backboard while maintaining proper spinal alignment. This method ensures minimal movement and reduces the risk of further injury to the patient's spine. Sliding the patient onto the backboard or log rolling the patient away from you may cause unnecessary twisting or bending of the spine, while applying the KED first is not necessary in this situation.

Given the symptoms of jaw and neck stiffness, along with the patient's history of a recent hand injury, the most likely explanation for his condition is tetanus. Tetanus is a bacterial infection caused by the bacteria Clostridium tetani, which enters the body through open wounds. It produces a toxin that affects the nervous system, leading to muscle stiffness and spasms. The fever also supports the diagnosis of tetanus. Meningitis could be a possibility, but the combination of symptoms and history points more towards tetanus. A viral infection or staph infection are less likely explanations in this case.

The correct answer is to assume that a spine injury exists, regardless of the neurologic findings. This means that even if there are no obvious neurological deficits, it is important to treat the patient as if they have a spinal cord injury. This is because spinal cord injuries can sometimes have delayed or subtle symptoms, and failure to immobilize the spine could potentially worsen the injury. By assuming that a spine injury exists, medical professionals can take appropriate precautions to prevent further damage and provide the necessary care to the patient.

The correct answer is to apply an icepack to the hematoma and monitor his level of consciousness. This is the most appropriate action because the icepack will help reduce swelling and inflammation in the area, which can help alleviate the severe headache. Monitoring his level of consciousness is important to ensure that there are no signs of worsening symptoms or neurological deficits. This will help determine if further medical intervention is necessary.

In cases where orotracheal intubation is not possible due to severe bleeding and maxillofacial trauma, nasotracheal intubation may also be challenging. Therefore, the next best option would be to perform a needle or surgical cricothyrotomy. This procedure involves creating an emergency airway through a small incision in the cricothyroid membrane to allow for ventilation. It is a quick and effective method to secure the airway in critical situations where other methods are not feasible. Pharmacologically assisted intubation and digital intubation are not suitable options in this scenario.

The correct answer is to carefully assess the scene for safety hazards. This is the first action that should be taken because the safety of the responder and the patient is of utmost importance. By assessing the scene for safety hazards, the responder can identify any potential dangers such as loose wires, unstable structures, or other hazardous materials that may pose a risk to themselves or the patient. This allows for appropriate measures to be taken to ensure a safe environment before providing medical care.

The spinal cord is a continuation of the central nervous system and exits the skull through the foramen magnum. The foramen magnum is a large opening at the base of the skull through which the spinal cord passes.

Covering both eyes to minimize further injury is the correct answer because it helps to protect the injured eye from any additional trauma or damage. By covering both eyes, the injured eye is shielded from bright light, foreign objects, or accidental contact, which can exacerbate the injury. Additionally, covering both eyes helps to prevent eye movement, reducing the risk of further injury or strain.

Motor or sensory deficits noted during the neurologic examination of a patient with a possible spinal cord injury should be documented and monitored. This is because these deficits can provide important information about the severity and location of the injury, as well as help guide treatment decisions. Monitoring these deficits over time can also help track the patient's progress and response to treatment.

The correct answer is "ventricles, cushion and protect the brain". Cerebrospinal fluid is manufactured in the ventricles of the brain and serves to cushion and protect the brain. It acts as a shock absorber, providing a protective layer between the brain and the skull, and helps to distribute nutrients and remove waste products from the brain.

Decerebrate posturing is a neurological condition that occurs due to damage to the brainstem. It is characterized by the extension of the arms and extension of the legs. This abnormal posture indicates dysfunction in the upper brainstem and suggests a more severe neurological injury. The extension of both the arms and legs indicates a loss of control and coordination of voluntary muscle movements. This type of posturing is often associated with a poor prognosis and indicates significant brain damage.

Chronic subdural hematomas are most commonly seen in patients who have alcoholism. Alcoholism can lead to a variety of health issues, including liver dysfunction and increased risk of falls and accidents. Chronic alcohol abuse can also impair the body's ability to form blood clots, making individuals more susceptible to bleeding in the brain. This increased risk of bleeding can result in the development of chronic subdural hematomas.

The correct answer is to protect his spine, insert a nasal airway, assist ventilations with a BVM and 100% O2, keep him warm and elevate his legs, transport at once, and establish vascular access en route to a trauma center. This is the most appropriate course of action for a patient who has been assaulted and is exhibiting signs of poor respiratory effort, weak pulse, and unresponsiveness. Protecting the spine helps prevent further injury, while inserting a nasal airway and providing ventilations with a BVM and 100% O2 ensures adequate oxygenation. Keeping the patient warm and elevating his legs helps improve circulation, and immediate transport to a trauma center allows for specialized care. Establishing vascular access en route allows for the administration of fluids and medications as needed.

A depressed fracture is the most common type of skull fracture that occurs following high energy direct trauma to a small surface area of the head with a blunt object. This type of fracture happens when the bone is pushed inward, causing a depression or indentation in the skull. It is often seen in cases where the force of the impact is concentrated on a small area, such as from a blow to the head with a blunt object. The depressed fracture can lead to neurological symptoms and may require surgical intervention to correct the deformity and relieve any pressure on the brain.

Autoregulation refers to the ability of the body to maintain a consistent blood flow to an organ or tissue despite changes in systemic blood pressure. In the case of cerebral autoregulation, it ensures that the brain receives a constant blood flow despite fluctuations in mean arterial pressure. This is important to maintain adequate oxygen and nutrient supply to the brain cells. Therefore, the correct answer is "an increase in mean arterial pressure to maintain cerebral blood flow."

The level of consciousness is the most important assessment parameter when evaluating the severity of a traumatic brain injury. This is because the level of consciousness can provide valuable information about the extent of brain damage and the overall functioning of the brain. A decrease in consciousness may indicate a more severe injury, while a normal or improving level of consciousness may suggest a less severe injury. Therefore, monitoring the level of consciousness is crucial in determining the severity of a traumatic brain injury and guiding appropriate treatment decisions.

The patient's presentation of abdominal breathing and use of accessory muscles in the neck suggests injury at or above the C3-C4 level. This is because the C3-C4 spinal segments innervate the diaphragm, which is the primary muscle responsible for breathing. When there is an injury at or above this level, the diaphragm may become paralyzed or weakened, leading to the use of accessory muscles in the neck and a shift towards abdominal breathing as a compensatory mechanism.

When assessing a patient with maxillofacial trauma, it is most important to protect the cervical spine and monitor the patient's neurologic status. This is because maxillofacial trauma can often be accompanied by injuries to the cervical spine, which can lead to serious complications if not properly managed. By protecting the cervical spine, healthcare professionals can prevent further damage and ensure the patient's safety. Additionally, monitoring the patient's neurologic status is crucial to identify any signs of neurological deficits or injuries that may require immediate intervention.

Elevating the extremity above the level of the heart is the correct answer because it helps to reduce blood flow to the injured area and can help control bleeding. By raising the arm, gravity assists in slowing down the blood flow, which can be effective in controlling the spurting blood. This technique, along with applying direct pressure, can help minimize blood loss and provide temporary stabilization until further medical assistance is available.

The correct answer is "has discoordination between the movements of both eyes." Dysconjugate gaze refers to a lack of coordination between the movements of both eyes. This can occur following an ocular injury, indicating damage to the nerves or muscles that control eye movement. It is not necessarily indicative of a basilar skull fracture or the need for ice application or eye irrigation.

The lumbar spine is especially susceptible to injury because it bears a significant amount of weight. The lumbar spine is located in the lower back and consists of five vertebrae that support the majority of the body's weight. This weight-bearing capacity makes the lumbar spine more prone to injury, such as herniated discs, muscle strains, and spinal stenosis. Additionally, the lumbar spine is involved in many daily activities, such as lifting and bending, which can further increase the risk of injury.

Prolonged immobilization of a patient on a long backboard can lead to pressure lesion development. This occurs due to the constant pressure exerted on the patient's skin by the backboard, which can cause tissue damage. Pressure lesions can range from mild redness and irritation to more severe ulcers or sores. It is important to regularly assess and reposition the patient to prevent these complications. Compression of the vena cava, increased intracranial pressure, and patient discomfort and frustration are also potential complications of prolonged immobilization, but pressure lesion development is the most significant one.

The patient's presentation suggests that he has suffered a significant traumatic injury, likely involving his spinal cord. His inability to move his lower extremities and the presence of pale, clammy skin above the level of his umbilicus indicate a potential spinal cord injury. The low pulse rate, weak blood pressure, and shallow respirations suggest that he is experiencing bradycardia and hypotension, which may be due to neurogenic shock. Therefore, the appropriate course of action is to assist ventilations as needed, apply spinal motion restriction precautions, keep him warm, begin transport, establish vascular access en route, administer crystalloid boluses in 200 mL increments, consider atropine for his bradycardia, and infuse dopamine if his blood pressure is refractory to fluid boluses.

When an unrestrained passenger's head strikes the windshield of a motor vehicle following rapid deceleration, compression injuries occur to the anterior portion of the brain and stretching or tearing injuries occur to the posterior portion of the brain. This is because the force of the impact causes the brain to move forward, resulting in compression of the front part of the brain against the skull. At the same time, the brain also experiences a stretching or tearing motion as it moves backwards and collides with the rear of the skull.

As the body ages, the intervertebral discs lose water content and become thinner. This is a natural process known as disc degeneration. The discs act as cushions between the vertebrae in the spine, providing flexibility and shock absorption. However, as they lose water content, they become less effective in their role, leading to a decrease in height and an increased risk of spinal problems such as herniated discs.

The correct answer is to remove his clothing, brush as much of the lime off him as possible, and flush the affected areas with copious amounts of water. This is the appropriate initial treatment for a chemical burn caused by lime. Removing the clothing helps to prevent further contact with the chemical, while brushing off the lime helps to remove any remaining particles. Flushing with water helps to dilute and remove the chemical from the skin, reducing the severity of the burn.

Beta receptor stimulation typically leads to positive cardiac inotropy (increased force of contraction), positive cardiac chronotropy (increased heart rate), and relaxation of bronchiole smooth muscle. However, it does not result in vascular smooth muscle contraction.

The correct answer is "after he or she is lowered to the ground". This means that the patient is first immobilized using the standing takedown technique while they are still in a standing position. Once the patient is secured and ready, they are then lowered to the ground and placed on the long backboard. After the patient is on the ground, straps are used to secure them to the board, ensuring that their spine remains immobilized during transportation.

Death following a head injury is almost always the result of trauma to the brain. Head injuries can cause severe damage to the brain, leading to various complications such as bleeding, swelling, and increased pressure within the skull. These can disrupt the normal functioning of the brain and its vital structures, leading to loss of consciousness, coma, and ultimately death. Trauma to the brain is a common cause of death in head injury cases, making it the most likely explanation for death in this scenario.

Alkali or strong acid burns to the eye can cause severe damage and should be treated immediately. Irrigation is the process of flushing the affected area with water or a saline solution to dilute and remove the chemical. It is crucial to irrigate the eye for a sufficient amount of time to ensure that all traces of the chemical are washed away. Therefore, the absolute minimum time for irrigation should be 20 minutes to effectively minimize the potential damage caused by the burn.

The spine is the major structural component of the axial skeleton because it serves as the central support structure for the entire body. It consists of 23 bones, called vertebrae, that articulate together to form the spinal column. These vertebrae are not irregular bones that are fused together, but rather individual bones that are stacked on top of each other and connected by joints. The spine provides support and strength for the rest of the body, including the appendicular skeleton which includes the limbs.

A compression or burst fracture of the cervical spine would most likely occur following a significant fall in which the patient lands head first. This is because the force of the fall and the impact on the head can cause a compression or burst fracture in the cervical spine. The weight of the body and the force of the fall would be concentrated on the neck, leading to potential damage to the vertebrae in the cervical spine.

The correct answer is to apply cool, wet dressings to the burn and elevate his arm. This is the initial management for burns to provide pain relief and prevent further damage. Applying ice directly to the burn can cause further injury and is not recommended. Starting an IV and administering morphine may be necessary for pain management, but it is not the initial step. Administering oxygen and applying an anesthetic cream are not the appropriate initial management for burns.

A complete spinal cord injury to the upper cervical spine will result in permanent loss of all cord mediated functions below the level of the injury. This means that the patient will lose all sensory and motor function below the injury site. This includes the ability to move limbs, feel sensations, and control bodily functions. The injury is considered permanent because the damaged spinal cord cannot regenerate or repair itself.

The correct answer is that the nasal septum may be slightly deviated to one side or the other. This is because the nasal septum is the partition that separates the two nasal cavities, and it is made up of both bone and cartilage. It is common for the nasal septum to be slightly deviated, which can lead to difficulty breathing or nasal congestion.

A ruptured tympanic membrane is extremely painful because it is a tear in the thin tissue that separates the outer and middle ear. However, it typically heals spontaneously without medical intervention. Therefore, while it may cause temporary discomfort, it does not commonly result in permanent hearing loss, CSF leakage from the ears, or an infection of the middle ear.

Neurogenic shock is a condition that occurs due to damage to the spinal cord, resulting in the disruption of the autonomic nervous system. It is characterized by a decrease in heart rate (bradycardia), low blood pressure, and loss of sympathetic tone. Flushed skin and hypothermia are also common signs of neurogenic shock as the body's ability to regulate temperature is impaired. However, diaphoresis, which refers to excessive sweating, is not typically associated with neurogenic shock.

The cranial vault is the correct answer because it refers to the structure made up of eight bones that surround and safeguard the brain. These bones include the frontal, parietal, temporal, and occipital bones, among others. The cranial vault acts as a protective shell for the brain, shielding it from external forces and potential injuries.

Patients with evidence of trauma above the clavicles should be considered at risk for an associated spine injury. The clavicles, also known as the collarbones, are located above the spine and any trauma occurring above this area may indicate a forceful impact that could potentially affect the spine. Therefore, it is important to consider the possibility of a spine injury in patients with trauma above the clavicles.

Public education and prevention strategies are the most effective method for decreasing morbidity and mortality associated with spinal cord injury. By educating the public about the causes, risks, and prevention of spinal cord injuries, individuals can take necessary precautions to avoid such injuries. Prevention strategies such as promoting safe behaviors, using protective equipment, and creating awareness about risky activities can significantly reduce the incidence of spinal cord injuries. This approach focuses on preventing the injury from occurring in the first place, which is more effective than simply treating the injury after it has already happened.

If a knife is impaled in the neck, it can cause obstruction of the airway, making it difficult for the person to breathe. In such cases, a cricothyrotomy may be required to establish a patent airway. A cricothyrotomy is a procedure in which an incision is made in the cricothyroid membrane to create an emergency airway. This allows air to bypass the obstruction and enter the lungs, ensuring that the person can breathe properly.

A subdural hematoma is a collection of blood between the brain and the dura mater, the outermost layer of the meninges. Common clinical findings associated with a subdural hematoma include an underlying skull fracture, a fluctuating level of consciousness, and unilateral hemiparesis or slurred speech. However, rapidly increasing ICP (intracranial pressure) is not typically associated with a subdural hematoma. Rapidly increasing ICP is more commonly seen in conditions such as traumatic brain injury or intracerebral hemorrhage.

When immobilizing a sitting patient with a vest type extrication device, it is important to first manually stabilize their head to prevent any further injury to the cervical spine. Once the head is stabilized, the next step is to assess distal pulse and sensory and motor function. This is crucial to determine if there is any compromise to blood flow or nerve function in the extremities, which could indicate a life-threatening condition. Only after assessing distal pulse and sensory and motor function should the appropriate size cervical collar be applied. Placing the vest device behind the patient should be done carefully, but it is not the immediate priority in this situation.

The child's lack of crying, along with tachypnea, tachycardia, cool and moist skin, and the absence of other injuries, suggest that he may be in a state of shock. In cases of severe burns, the body's stress response can lead to decreased blood sugar levels, potentially causing hypoglycemia. Therefore, it is important to assess the child's blood glucose level to determine if hypoglycemia is present and provide appropriate treatment if necessary.

The most appropriate treatment for this patient involves applying a CPAP device, monitoring his cardiac rhythm for dysrhythmias, establishing IV or IO access at the scene, administering a 500 mL crystalloid bolus, initiating transport, and administering atropine en route to prevent bradycardia. This treatment plan addresses the patient's respiratory distress by providing positive pressure ventilation through the CPAP device. Monitoring the cardiac rhythm is important to identify any dysrhythmias that may require further intervention. Establishing IV or IO access allows for the administration of fluids to address the patient's low blood pressure. Administering atropine en route can help prevent bradycardia, which may be a complication of the patient's low blood pressure. Transporting the patient to a facility for further evaluation and treatment is also necessary.
