TNCC EXAM 2026 WITH QUESTIONS
AND ANSWERS
1.What is the effect of hypothermia on the oxyhemoglobin dissociation
curve - correct answer-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? - correct answer-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? - correct answer-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 - correct answer-
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? - correct answer-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? - correct answer-
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? - correct
answer-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.
You are caring for a patient who was involved in a motor vehicle crash and
is 32 weeks pregnant. Findings of your secondary survey include
abdominal pain on palpation, fundal height at the costal margin, and some
dark bloody show. Varying accelerations and decelerations are noted on
