Final answer:
A client with deep vein thrombosis (DVT) receiving a continuous intravenous heparin infusion and experiencing tarry, black diarrhea and abdominal pain should have the heparin infusion discontinued, notify the healthcare provider, and assess the client's vital signs.
Step-by-step explanation:
Based on the symptoms described, the client with deep vein thrombosis (DVT) who is receiving a continuous intravenous heparin infusion may be experiencing a complication called gastrointestinal bleeding. Gastrointestinal bleeding can present as tarry, black diarrhea and abdominal pain.
The nurse should implement the following actions:
- Discontinue the heparin infusion: Heparin is an anticoagulant medication and can increase the risk of bleeding. Discontinuing the infusion will help prevent further complications.
- Notify the healthcare provider: The healthcare provider should be informed about the client's symptoms and the discontinuation of the heparin infusion. They may need to order further diagnostic tests or adjust the client's treatment plan.
- Assess the client's vital signs: Monitoring the client's vital signs is important to detect any changes in blood pressure or heart rate that may indicate worsening bleeding or shock.
