A.It causes less spinal motion than the lift-and-slide maneuver B.It is recommended for patients with unstable pelvic fractures C.It should be avoided with a suspected spine injury prior to imaging D.It decreases the risk of hemorrhage from unstable pelvic injuries

Answer:

It should be avoided with a suspected spine injury prior to imaging Question 2: A severely injured patient has been intubated and is being mechanically ventilated.The patient has received a balanced resuscitation including multiple blood products. Under which circumstance will it be harder for the hemoglobin to release oxygen to the tissues?A.Decreased pH B.Elevated carbon dioxide level C.Decreased body temperature D.Increased metabolic demand

Answer:

C.Decreased body temperature Question 3: A patient with a traumatic brain injury has a mean arterial pressure (MAP) of 65 mm Hg (8.66 kPa) and an intracranial pressure (ICP) of 22 mm Hg (2.93 kPa). Which finding is most likely an indication of the body's response to these findings?A.Reflex hypotension B.Increased respiratory effort C.Reflex tachycardia D.Widening pulse pressure

Answer:

D.Widening pulse pressure Question 4: A patient is brought to the emergency department with chest pain and shortness of breath following a high-speed motor vehicle collision in which they were the unrestrained driver. There is crepitus to the left chest with clear and equal breath sounds. The vital signs are BP 80/40 mmHg, HR 140 beats/minute, and RR 40 breaths/minute. Cardiac monitor shows sinus tachycardia with premature ventricular contractions. These findings are most consistent with which type of shock?A.Cardiogenic B.Neurogenic C.Hypovolemic D.Obstructive

Answer:

A.Cardiogenic Question 5: When should the definitive calculation for intravenous fluid resuscitation rate be performed for a patient with burns?A.As soon as the patient arrives B.During the secondary survey C.Should only be done at a burn center D.During the primary survey

Answer:

B.During the secondary surveyt Question 6: A trauma patient who is 30-weeks pregnant arrives at the emergency department following a motor vehicle collision. Which normal physiologic change should be considered when assessing ventilatory status?A.Increased functional reserve capacity B.Increased oxygen consumption C.Decreased minute ventilation D.Slower desaturation rates with apnea

Answer:

B.Increased oxygen consumption Question 7: What is the most important consideration during the initial assessment when caring for an older adult who has sustained serious injuries?A.They are likely to be fearful in the emergency department B.Medical history including current medications C.Availability of support systems after discharge D.Accessibility to a primary care physician

Answer:

B.Medical history including current medications Question 8: A patient has uncontrolled bleeding from a wound to his right upper extremity. What is the priority intervention?A.Initiate two intravenous access sites B.Place the patient on supplemental oxygen C.Apply direct pressure to the wound D.Use a tourniquet to control the bleeding

Answer:

C.Apply direct pressure to the wound Question 9: A patient arrives with a large metal rod embedded in their left thigh and no active bleeding. Which intervention is most appropriate for this patient?A.Remove the rod immediately to facilitate cleansing.B.Apply a tourniquet to the leg above the metal rod.C.Hold antibiotics until after the rod is removed.D.Prepare the patient for surgery to remove the rod.

Answer:

D.Prepare the patient for surgery to remove the rod.Question 10: The trauma nurse is caring for an unrestrained driver who struck their head on the windshield following a high-speed MVC. The patient has been diagnosed with an anterior spinal cord injury at the level of C6. Which assessment finding would be most concerning?A.Distension of the bladder B.Incontinence of stool C.Increasing work of breathing D.Inability to move the legs

Answer:

C.Increasing work of breathing

Question 11: An obese trauma patient requires intubation. Assuming there are no

contraindications, which position will provide the best visualization for insertion of the endotracheal tube?A.Reverse Trendelenburg B.Lying on side C.Ramped D.Supine

Answer:

C.Ramped

Question 12: A patient arrives with a large open chest wound after being assaulted with a machete. Prehospital providers placed a nonporous dressing over the chest wound and taped it on three sides. The patient is now showing signs of anxiety, restlessness, severe respiratory distress, cyanosis, and decreasing blood pressure. Which of the following is the MOST appropriate immediate intervention?A.Needle decompression B.Tube thoracostomy C.Dressing removal D.Surgical repair

Answer:

C.Dressing removal Question 13: A patient is brought to the emergency department following a snowmobile crash with prolonged exposure time prior to transport. The patient is confused. Vital signs are BP 96/54 mm Hg, HR 114 beats/minute, RR 24 breaths/minute, T 34.6oC (94.2oF) and an SpO2 of 90% on oxygen at 15L per non-rebreather mask. Other findings include ETCO2 24, serum lactate of 6 mmol/L, and a pH of 6.8. Based on these findings, what is the most appropriate intervention?A.Initiate warming measures B.Titrate oxygen to 6 L per nasal cannula C.Bolus with 500 mL isotonic crystalloids D.Vigorously massage the extremities

Answer:

A.Initiate warming measures Question 14: An adult patient who sustained a severe head trauma has been intubated and is being manually ventilated via a bag-mask device at a rate of 18 breaths/minute. The patient has received one intravenous fluid bolus of 500 mL of warmed isotonic crystalloid solution. The PaCO2 is 30 mm Hg (4.0 kPa), and the pulse oximetry is 92%. BP is 142/70 mm Hg. What is the most important intervention to manage the cerebral blood flow?A.Decrease the rate of manual ventilation.B.Initiate another fluid bolus.C.Recheck endotracheal tube placement.D.Increase the amount of oxygen delivered.

Answer:

A.Decrease the rate of manual ventilation.
