Today’s question targets early recognition of medication-related bleeding and the nurse’s first priority action. This matters because small changes in assessment can signal a serious complication before a patient becomes unstable. On a real shift, nurses often catch the problem first, and the right next step can prevent rapid deterioration.
Clinical Scenario
A 72-year-old man is admitted to a medical-surgical unit with new-onset atrial fibrillation. He started an intravenous heparin infusion 18 hours ago and is on continuous cardiac monitoring. His history includes hypertension, stage 3 chronic kidney disease, and a remote peptic ulcer. At 0700, the nurse notes that he is more tired than during the night shift. He reports mild lower back pain and says, “I feel a little dizzy when I sit up.”
His current assessment findings are: blood pressure 98/62 mm Hg, heart rate 108/min, respiratory rate 20/min, oxygen saturation 96% on room air, and temperature 36.8 C. His urine in the catheter tubing appears pink-red. There is a large, firm bruised area over the left flank that was not documented earlier. Morning laboratory results show hemoglobin decreased from 12.8 g/dL yesterday to 9.6 g/dL today. The activated partial thromboplastin time is 96 seconds.
The Question
Which action should the nurse take first?
Answer Choices
- A. Slow the heparin infusion rate and recheck the activated partial thromboplastin time in 1 hour
- B. Stop the heparin infusion and notify the provider immediately
- C. Administer the prescribed PRN acetaminophen for back pain and continue to monitor
- D. Encourage oral fluids to improve blood pressure and repeat vital signs in 30 minutes
Correct Answer
B. Stop the heparin infusion and notify the provider immediately
Detailed Rationale
This patient shows multiple signs of active bleeding while receiving anticoagulant therapy. The nurse should recognize a pattern, not just one abnormal finding. The pink-red urine suggests hematuria. The new flank bruising and back pain raise concern for internal bleeding, including possible retroperitoneal bleeding. The drop in hemoglobin supports blood loss. His blood pressure is lower than expected, and dizziness with sitting up suggests reduced circulating volume. The activated partial thromboplastin time of 96 seconds is also markedly elevated, which means the heparin effect is too strong.
The first priority is to stop the source of harm. Continuing heparin, even at a slower rate, could worsen bleeding. After stopping the infusion, the nurse should notify the provider right away because the patient may need urgent evaluation, repeat labs, and reversal with protamine sulfate if prescribed. The nurse should also assess the patient’s airway, breathing, circulation, level of consciousness, extent of bruising, urine output, and any additional bleeding sites such as gums, stool, IV sites, or abdominal distention.
Monitoring matters here because bleeding can become hemodynamic instability quickly. The nurse should obtain frequent vital signs, watch for increasing tachycardia or falling blood pressure, and prepare for stat laboratory work if ordered, such as repeat hemoglobin, hematocrit, platelet count, coagulation studies, and kidney function tests. Because the patient has chronic kidney disease, medication clearance may be less predictable, which can increase risk for complications.
This scenario also tests prioritization. The patient is not just “at risk” for bleeding. He is showing evidence of bleeding now. NCLEX questions often hinge on that difference. When a harmful medication is actively contributing to a serious complication, the immediate nursing action is usually to stop or hold it and escalate care.
Why the Other Options Are Wrong
A. Slow the heparin infusion rate and recheck the activated partial thromboplastin time in 1 hour
This is unsafe because the patient already has signs of active bleeding, not just an abnormal lab value. A high activated partial thromboplastin time alone might lead to a rate adjustment depending on protocol, but active hematuria, falling hemoglobin, flank ecchymosis, and symptoms of instability change the priority. The infusion should be stopped, not reduced.
C. Administer the prescribed PRN acetaminophen for back pain and continue to monitor
Back pain is a clue, not the main problem. In a patient on heparin, new back or flank pain can point to internal bleeding. Treating the pain without addressing the cause delays needed intervention. Monitoring alone is not enough when the patient already shows evidence of worsening blood loss.
D. Encourage oral fluids to improve blood pressure and repeat vital signs in 30 minutes
This delays action and does not treat the underlying problem. Fluids by mouth are not the first response to suspected anticoagulant-related bleeding. Also, waiting 30 minutes could allow further deterioration. The blood pressure, dizziness, and lab changes suggest that immediate escalation is needed.
Key Takeaways
- In a patient receiving heparin, new bruising, hematuria, back or flank pain, and a falling hemoglobin can signal internal bleeding.
- A prolonged activated partial thromboplastin time matters more when it matches the clinical picture.
- When active bleeding is suspected, the nurse’s first priority is to stop the heparin infusion and notify the provider.
- Do not focus on one symptom in isolation. Put the assessment findings together.
- Watch for signs of hemodynamic decline: dizziness, tachycardia, hypotension, reduced urine output, and increasing weakness.
What you’d do on shift:
- Stop the heparin infusion immediately.
- Assess vital signs, mental status, urine, skin, abdomen, and IV sites.
- Notify the provider with clear data: symptoms, labs, vital signs, and bleeding findings.
- Prepare for repeat labs and possible reversal therapy if ordered.
- Continue close monitoring for worsening shock or expanding bleeding.
Quick Practice Extension
1. A patient on heparin has bleeding gums while brushing teeth, but vital signs are stable and hemoglobin is unchanged. What assessment findings would help you decide whether this is minor bleeding or the start of a larger problem?
2. After the provider discontinues heparin and prescribes protamine sulfate, what adverse reactions and follow-up assessments should the nurse monitor for during and after administration?
