A newborn is placed under a radiant heat warmer. The nurse knows that thermoregulation presents a problem for newborns because:
 
  1. their renal function is not fully developed and heat is lost in the urine.
  2. their small body surface area favors heat loss more rapidly than an adult's body surface area.
  3. they have a relatively thin layer of subcutaneous fat that provides poor insulation.
  4. their normal flexed posture favors heat loss through perspiration.

Question 2

After several weeks of caring for a child who is dying, a nurse finds herself hoping that the child will die on the weekend she is scheduled not to work. This behavior is consistent with which stage of grief?
 
  A) Acceptance
  B) Bargaining
  C) Anger
  D) Depression

Answer to Question 1

3
1. Incorrect. Heat loss does not occur through urination.
2. Incorrect. Newborns have a larger body surface-to-body weight ratio than adults.
3. Correct. The newborn has little thermal insulation. Furthermore, the blood vessels are closer to the surface of the skin. Changes in environmental temperature alter the temperature of the blood, thereby influencing temperature regulation centers in the hypothalamus.
4. Incorrect. The flexed position of the newborn helps guard against heat loss because it di-minishes the amount of body surface exposed to the environment.

B
