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
Correct Answer: C
Rationale: Histamine-2 receptor antagonists when given with warfarin place the client at an increased risk for bleeding.

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.

A nurse is caring for a client who is prescribed omeprazole for a duodenal ulcer. The client is also taking benzodiazepines for the management of a seizure disorder. The nurse would assess the client for which of the following?
- A. Decreased absorption of the proton pump inhibitor
- B. Risk for toxic level of benzodiazepines
- C. Increased risk of respiratory depression
- D. Increased risk of bleeding
Correct Answer: B
Rationale: When the proton pump inhibitor is administered with benzodiazepines, there will be a risk for a toxic level of benzodiazepines. When the client is administered sucralfate with the proton pump inhibitor, there will be a decrease in absorption of the proton pump inhibitor. When the client is administered an antacid with opioid analgesics, there will be an increased risk of respiratory depression. There will be an increased risk of bleeding when the client is taking oral anticoagulants with the proton pump inhibitor.
