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.

3. 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.
4.Which of the following is an expected finding in a patient with a tube thoracostomy connectedto

is placed correctly in the pleural space.
