Today’s NCLEX question targets early recognition of a high-risk medication complication and choosing the safest first nursing action. This matters in real nursing because medication side effects can change fast. A nurse who catches the pattern early can prevent bleeding, shock, or a rapid transfer to intensive care.
Clinical Scenario
A 68-year-old man is on a medical-surgical unit after being admitted with a left lower leg deep vein thrombosis. His history includes hypertension, stage 3 chronic kidney disease, and osteoarthritis. He started a continuous heparin infusion 24 hours ago. During morning rounds, the nurse notes that the patient says, “My back feels tight and sore all of a sudden.” He looks pale and restless. Assessment findings include heart rate 112/min, blood pressure 94/58 mm Hg, respirations 22/min, and oxygen saturation 96% on room air. The heparin infusion is running as ordered. The most recent laboratory results show a hemoglobin drop from 13.4 g/dL on admission to 10.2 g/dL this morning. The activated partial thromboplastin time is above the therapeutic range.
The Question
Which action should the nurse take first?
Answer Choices
- A. Reassure the patient that mild back pain is common with bed rest and reposition him with a pillow
- B. Stop the heparin infusion and notify the provider immediately
- C. Administer the prescribed PRN opioid analgesic for pain rated 6/10
- D. Encourage the patient to increase oral fluids to improve blood pressure
Correct Answer
B. Stop the heparin infusion and notify the provider immediately
Detailed Rationale
This patient has several signs that point to possible internal bleeding related to heparin therapy. The sudden back pain is the key assessment detail. In a patient receiving anticoagulation, new back, flank, or abdominal pain can signal retroperitoneal bleeding. That type of bleeding can be hard to see from the outside, but it can become life-threatening quickly.
The nurse should connect the clues step by step:
- He is receiving a heparin infusion, which increases bleeding risk.
- His activated partial thromboplastin time is above the therapeutic range, which means the anticoagulant effect may be too strong.
- His hemoglobin has dropped significantly in a short time, suggesting blood loss.
- He is pale, tachycardic, hypotensive, and restless. Those are concerning signs of hemodynamic instability.
- The new sudden back pain raises concern for internal hemorrhage, not simple musculoskeletal discomfort.
The first priority is to prevent more anticoagulation. Stopping the heparin infusion removes the likely cause of ongoing bleeding. After that, the nurse should notify the provider right away and be ready for urgent follow-up actions. These may include repeat vital signs, focused assessment, stat laboratory work such as hemoglobin and hematocrit, preparation to give protamine sulfate if prescribed, and close monitoring for worsening shock.
What should the nurse assess? The nurse should reassess vital signs, level of consciousness, skin color, pain location and intensity, and any visible bleeding from gums, urine, stool, or IV sites. The nurse should also review recent lab trends, especially hemoglobin, hematocrit, platelet count, and coagulation studies. Because the patient is unstable, the nurse should stay with the patient or ensure close observation while help is arranged.
What should the nurse do next after stopping the infusion and calling the provider? Anticipate orders for a reversal agent, possible imaging, additional IV access, fluid support, and maybe blood products depending on severity. The nurse should also implement safety measures such as fall precautions, because hypotension and blood loss increase the risk of collapse.
What should the nurse monitor? Watch for worsening hypotension, increasing heart rate, decreased urine output, new confusion, expanding pain, and further lab decline. These signs show the bleed may still be progressing.
Why the Other Options Are Wrong
A. Reassure the patient that mild back pain is common with bed rest and reposition him with a pillow
This delays treatment of a possible internal hemorrhage. The pain is not an isolated comfort issue. It appeared suddenly and is paired with hypotension, tachycardia, pallor, and falling hemoglobin. Reassurance without action ignores a dangerous pattern.
C. Administer the prescribed PRN opioid analgesic for pain rated 6/10
Pain medicine may be needed later, but it is not the priority. Giving an opioid first could also cloud assessment by masking worsening symptoms and may contribute to hypotension. The nurse must address the likely cause of the pain before treating the symptom.
D. Encourage the patient to increase oral fluids to improve blood pressure
This is unsafe and inadequate. Oral fluids do not treat active internal bleeding. A hypotensive patient on a heparin infusion with signs of blood loss needs urgent medical evaluation, not simple hydration advice. If support is needed, it will likely require IV management and rapid reassessment.
Key Takeaways
- In a patient on heparin, sudden back, flank, or abdominal pain can mean internal bleeding.
- An elevated activated partial thromboplastin time plus a falling hemoglobin is a major warning sign.
- Tachycardia, hypotension, pallor, and restlessness suggest instability and possible shock.
- The safest first action is to stop the anticoagulant and notify the provider immediately.
- Treat the cause first. Do not let comfort measures distract from a life-threatening problem.
What you’d do on shift:
- Stop the heparin infusion.
- Reassess vital signs and mental status right away.
- Check for visible and hidden signs of bleeding.
- Review coagulation labs and hemoglobin trend.
- Notify the provider or rapid response team based on severity.
- Prepare for reversal, further labs, and possible blood product support.
Quick Practice Extension
1. A patient receiving heparin develops new hematuria but remains hemodynamically stable. What assessment findings would help you decide how urgent the situation is?
2. A provider prescribes protamine sulfate for a patient with suspected heparin-related bleeding. What should the nurse monitor during and after administration?
