ANSWERS GRADED A+ 100% GUARANTEED SUCCESS.
1. What is the effect of hypothermia on the oxyhemoglobin dissociation curve
ANS >> - 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.
2. 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
appropriateto remove the cervical collar? ANS >> - After a
physical examination if the patient has no radiologic abnormalities on CT A
CT is recommended for spinal clearance in an impaired patient.

,3. The nurse is caring for a 120 kg male brought in after a warehouse fire and
iscalculating 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? ANS >> - 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.
4. Which of the following is an expected finding in a patient with a tube
thoracostomy connected to a chest drainage system ANS >> -
Fluctuation in the water seal chamber Fluctuation in the water seal chamber

indicates the tube is placed correctly in the pleural space.
5. A 35-year-old male presents with facial trauma after being struck in the
facewith a baseball. A teardrop-shaped left pupil is noted on exam. What
type of injury is suspected? ANS >> - Globe rupture A
teardrop-shaped pupil suggests a globe rupture.
6. A patient with a complete spinal cord injury in neurogenic shock will
demonstrate hypotension and which other clinical signs? ANS >> -
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.
7. Which of the following patients warrants referral to a burn center?
ANS >> - A 52-year-old diabetic male with a partial-thickness burn to
