A client is admitted for deep vein thrombosis and is receiving 5,000 units of heparin subcutaneously every 8 hours. In case of a serious bleeding reaction, the nurse has which of the following drugs readily available?

  • warfarin
  • potassium chloride
  • vitamin K
  • protamine sulfate
Number 4 is correct.
Protamine sulfate is needed to neutralize the effects of heparin. Warfarin is the generic name for Coumadin, which is used to prevent blood clot formation. Potassium chloride is used to treat or prevent low amounts of potassium. Vitamin K is the antidote in case of Coumadin overdose.
