Q1Which of the following patients are at the lowest risk for complications after a compound fracture?
Show answer
✓ Correct answer: Patients with a history of diabetes
Answer: Patients with a history of diabetes Several factors increase a patient's risk of complications after a compound fracture. These include poor nutritional status, a compromised immune system, and taking medications like corticosteroids. Patients with diabetes may face challenges in healing but are at the lowest risk compared to those with the other conditions described.
Q2Which of the following is not a factor that increases the risk of infection in a burn wound?
Show answer
✓ Correct answer: The presence of superficial burns
Answer: The presence of superficial burns Superficial burns, while painful, generally do not significantly increase the risk of infection. They affect only the outermost layer of skin and typically heal without complications. The presence of eschar can create an environment conducive to bacterial growth. Poor nutritional status of the patient and prolonged hospitalization also increases the risk of infection developing.
Q3Which of the following statements is accurate regarding patients with electrical burns?
Show answer
✓ Correct answer: Electrical burns can cause internal injuries without significant external damage
Answer: Electrical burns can cause internal injuries without significant external damage Electrical burns can lead to significant internal injuries such as muscle damage, nerve damage, and organ injuries without obvious external signs on the skin. It is crucial to monitor patients with electrical burns for potential cardiac arrhythmias and other internal complications.
Q4A patient is brought to the ER with a segmental fracture of the right femur. What type of force is most likely to cause this type of fracture?
Show answer
✓ Correct answer: Axial compression
Answer: Axial compression Axial compression forces are applied along the axis of the bone, often resulting in segmental fractures when the bone is compressed internally. Shear forces involve sliding actions that occur in parallel planes, causing different fracture patterns. Torsion forces involve twisting, potentially leading to spiral fractures. Bending forces refer to an application that causes compression on one side and tension on the other, producing transverse or oblique fractures.
Q5An elderly patient presents with a severe tibial fracture following a motor vehicle collision. For how many days after the injury should the trauma nurse remain vigilant for signs of developing compartment syndrome?
Show answer
✓ Correct answer: 3 days
Answer: 3 days The risk of compartment syndrome is highest within the first 72 hours (3 days) following the injury due to the potential for swelling and increased pressure within the muscle compartments. After this period, the likelihood of compartment syndrome decreases significantly.
Q6A 52-year-old male construction worker fell from a height and was pinned under heavy machinery for an extended period, sustaining a crush injury to his right arm. Upon examination, the right arm has extensive soft tissue damage and compromised circulation. What is the most likely necessary treatment for this type of injury?
Show answer
✓ Correct answer: Amputation of the extremity
Answer: Amputation of the extremity Crush injuries that lead to extensive soft tissue damage, compromised circulation, and potential nerve involvement often necessitate amputation due to the severity of the damage and limited efficacy of grafts in such cases. While amputation might be necessary, it is not likely to be fatal if treated with amputation, as opposed to attempting skin and/or muscle grafts, which are generally ineffective for extensive crush injuries.
Q7Which of the following conditions is least likely to contribute to secondary cervical spine injury?
Show answer
✓ Correct answer: Hypothermia
Answer: Hypothermia Secondary injuries to the cervical spine can occur after an initial trauma and can exacerbate the primary injury. Hypotension, ischemia, and edema can all contribute to secondary cervical spine injury. Hypothermia, however, is less likely to contribute and may even have a protective effect.
Q8A 30-year-old male construction worker falls from a height of 10 feet while working on scaffolding. He lands directly on his feet. Based on the mechanism of injury, which of the following vertebrae is most likely to be injured?
Show answer
✓ Correct answer: L1
Answer: L1 Vertical compression injuries often occur in individuals who land on their feet from significant heights. The impact force travels upward through the legs and pelvis, frequently causing fractures in the lumbar vertebrae due to the axial load. L1 is the most commonly affected vertebra in such scenarios. L1 is part of the upper lumbar spine, which is susceptible to injury due to the vertical compression forces.
Q9What is the most critical initial step in the management of a patient with a neck stab wound?
Show answer
✓ Correct answer: Airway management
Answer: Airway management In cases of neck trauma, particularly with a stab wound, the most critical initial step is to ensure the airway is secure and not compromised, as airway obstruction is a life-threatening condition. While controlling bleeding is crucial, it follows after airway management. Infection prevention is important for long-term care but not immediately life-threatening. Assessing neurological deficits is also essential but secondary to ensuring airway patency.
Q10A nurse is evaluating a 25-year-old male who was elbowed in the throat during a basketball game. Which of the following findings one hour after the injury is not consistent with a minor throat trauma?
Show answer
✓ Correct answer: Difficulty breathing
Answer: Difficulty breathing Difficulty breathing is not expected with minor throat trauma and could indicate a more severe injury such as airway obstruction or a significant laryngeal injury. Mild hoarseness, slight pain swallowing, and minor bruising are common findings with minor throat trauma.
