TCRN Test Questions And Answers SOLVED 100% CORRECT TCRNA transcranial doppler is obtained for a patient with a traumatic subarachnoid hemorrhage. The doppler is positive for vasospasm. The trauma nurse would expect which of the following medications to be prescribed? - A vasospasm is a known complication of subarachnoid hemorrhages. Calcium channel blockers are used to prevent or reverse vasospasms and are frequently used in the treatment of a subarachnoid hemorrhage. Metoprolol, Hydralazine and Lisinopril are not calcium channel blockers and would not be effective to prevent and treat vasospasms caused by a subarachnoid hemorrhage Which chamber of the heart is most likely to be affected in blunt cardiac injuries? - Given the anatomical position of the heart in the chest, the right ventricle is most exposed to the anterior portion of the chest wall and is most likely to be injured in a blunt cardiac injury. Patients with blunt cardiac injuries frequently experience signs of right ventricular failure. Additional findings that are associated with blunt cardiac injuries include hypotension, atrial fibrillation, unexplained sinus tachycardia, multiple PVCs, ST segment changes and right bundle branch blocks. The left atrium, right atrium and left ventricle are less likely to be injured in a blunt cardiac injury. A widened mediastinum is noted on the chest x-ray of a traumatically injured hypotensive patient. The trauma nurse would anticipate gathering which of the following pieces of equipment as the highest priority in this scenario? - A widened mediastinum on chest x-ray, accompanied by hypotension, is strongly indicative of an aortic injury. One of the most life-threatening complications of an aortic injury is blood loss, which can be treated by giving blood products via a rapid transfuser. Although patient assessment may be enhanced by inserting an arterial line, this is less of a priority than giving fluids rapidly. A chest tube is placed in the pleural space rather than the mediastinum and is therefore not indicated in this scenario. Similarly, there is nothing in this scenario that indicates a pericardiocentesis is indicated so this is not a higher priority than preparing a rapid transfuser. A properly applied pelvic binder sits across the: - A properly applied pelvic binder is applied across the greater trochanters of the femur. This allows for optimal compression of the pelvis to control bleeding. Applying it across the midshaft of the femur is too low and would provide no therapeutic benefit. Applying it across the pelvic ring or the iliac crests is too high and could actually separate the pelvis further, increasing bleeding and internal damage. Treatment for an extraperitoneal bladder rupture will most likely include: - Bladder lacerations that are located below the pelvic peritoneum are diagnosed as an extraperitoneal bladder rupture. If a laceration is found along with pelvic peritoneum, it would then be classified as an intraperitoneal bladder rupture. Management of an extraperitoneal bladder rupture involves urinary catheterization (urethral or suprapubic) to facilitate urinary drainage from the bladder. Intraperitoneal bladder ruptures require surgical intervention for definitive closure. An isolated extraperitoneal bladder rupture does not require emergent surgical repair or interventional radiology.
