During initial rounds, the nurse notes that a dobutamine infusion has extrava
 
  sated into the forearm of a patient. After stopping the infusion, the nurse follows standing orders and immediately injects phentolamine (Regitine) subcutaneously in a circular fashion around the extravasation site. What is the mechanism of action of the phentolamine in this situation?
  a. It neutralizes the extravasated dobutamine immediately.
  b. It causes arterial vasoconstriction and reduced pain and swelling at the site.
  c. It increases peripheral vascular resistance and reduces arterial pressure at the site.
  d. It increases blood flow to the ischemic site by vasodilation to prevent tissue damage.
