A client is prescribed ranitidine. A review of the client's medication history reveals that she also takes warfarin for treatment of deep vein thrombosis. The nurse would monitor the client for which of the following?
A) Decreased white blood cell count
B) Increased risk of respiratory depression
C) Increased risk for bleeding
D) Decreased seizure threshold
Ans: C
Feedback:
Histamine-2 receptor antagonists when given with warfarin place the client at an increased risk for bleeding. A decreased white blood cell count occurs when histamine-2 receptor antagonists are given with carmustine. An increased risk of respiratory depression occurs when histamine-2 receptor antagonists are given with opioid analgesics. This class of drugs does not interact with any antiseizure medications.
