TNCC Exam 8th edition study
Questions and Answers 100% Pass
1.What is the effect of hypothermia on the oxyhemoglobin dissociation curve -
✔✔Hemoglobin does not readily release oxygen for use by the tissues A shift to the left
occurs in an environment of low metabolic demand (hypothermia, hypocapnia,
alkalosis), increasing hemoglobin's affinity for oxygen.
EMS arrives with the intoxicated driver of a car involved in a motor vehicle crash. EMS
reports significant damage to the driver's side of the car. The patient is asking to have
the cervical collar removed. When it is appropriate to remove the cervical collar? -
✔✔After a physical examination if the patient has no radiologic abnormalities on CT A
CT is recommended for spinal clearance in an impaired patient.
The nurse is caring for a 120 kg male brought in after a warehouse fire and is calculating
the patient's fluid resuscitation needs. He has painful red blistering to the entire surface
of both upper extremities and superficial burns to the anterior chest. Using the modified
Lund and Browder chart to calculate the total body surface area burned, how much IV
fluid would be administered in the first 8 hours? - ✔✔2280 mL Both upper arms = 8%,

, both lower arms = 6%, and both hands = 5%, yielding 19 * 2 * 120 = 4560 mL. Half of the
total is equal to 2280 mL. Superficial burns are not included in the TBSA calculation for
fluid resuscitation.
Which of the following is an expected finding in a patient with a tube thoracostomy
connected to a chest drainage system - ✔✔Fluctuation in the water seal chamber
Fluctuation in the water seal chamber indicates the tube is placed correctly in the
pleural space.
.A 35-year-old male presents with facial trauma after being struck in the face with a
baseball. A teardrop-shaped left pupil is noted on exam. What type of injury is
suspected? - ✔✔Globe rupture A teardrop-shaped pupil suggests a globe rupture.
.A patient with a complete spinal cord injury in neurogenic shock will demonstrate
hypotension and which other clinical signs? - ✔✔Bradycardia and absent motor
function below the level of injury Patients with a complete spinal cord injury will have
absent motor function below the level of the lesion. They become hypotensive and
bradycardic due to loss of autonomic nervous system function.
Which of the following patients warrants referral to a burn center? - ✔✔A 52-year-old
diabetic male with a partial-thickness burn to the left lower leg This patient has a 7%
TBSA burn with a preexisting medical history that could complicate management,
prolong recovery, or affect mortality.
