A patient who has cancer asks the nurse about using acupuncture to manage cancer pain. What will the nurse tell this patient?
 
  a. Acupuncture is not an effective treatment for cancer pain and should not be used.
  b. Studies to date do not clearly indicate effectiveness of acupuncture for alleviat-ing cancer pain.
  c. Transcutaneous electrical nerve stimula-tion (TENS) has been shown to be more effective than acupuncture.
  d. There is good evidence to suggest that acupuncture is an effective adjunct treat-ment for cancer pain.

Question 2

A patient is admitted to the intensive care unit for treatment of shock. The prescriber orders isoproterenol Isuprel. The nurse expects this drug to increase tissue perfusion in this patient by activating:
 
  a. alpha1 receptors to cause vasoconstriction.
  b. alpha1 receptors to increase blood pressure.
  c. beta1 receptors to cause a positive ino-tropic effect.
  d. beta2 receptors to cause bronchodilation.

Answer to Question 1

B
Studies regarding acupuncture for treatment for cancer pain have been few and not well designed, so there is insufficient evidence to support its use. However, there have not been definitive studies showing that it does not work. TENS has not been well-studied, so findings about its use are inconclusive.

Answer to Question 2

C
Isoproterenol is used for shock because of its actions on beta1 receptors in the heart. It has a posi-tive inotropic effect, which improves cardiac output and thus increases tissue perfusion. Isopro-terenol does not affect alpha1 receptors. Although it activates beta2 receptors to cause bronchodi-lation, this is not indicated for the treatment of shock.
