NCLEX Question of the Day – Friday, March 06, 2026

Today’s question targets safe anticoagulant management. You will connect an abnormal lab to the next right action. This matters on real units because heparin errors can cause rapid, life-threatening bleeding. Nurses prevent harm by reading the data, acting fast, and knowing the antidote.

Clinical Scenario

A 64-year-old man is on a medical-surgical unit for a left-leg deep vein thrombosis. He started a weight-based IV heparin infusion 6 hours ago via a smart pump. History includes hypertension and type 2 diabetes. He reports no pain. You note oozing at the IV site and pink-tinged urine in the urinal. Vital signs: BP 102/64, HR 98, RR 16, SpO2 96% on room air. The aPTT returns at 118 seconds. The unit’s therapeutic goal is 60–80 seconds.

The Question

Which action should the nurse take first?

Answer Choices

1. A. Stop the heparin infusion and assess for bleeding; notify the provider and prepare protamine sulfate.
2. B. Reduce the heparin infusion rate by 50% and recheck the aPTT in 6 hours.
3. C. Continue the current rate and encourage oral fluids to dilute the medication.
4. D. Administer warfarin now to begin transition to oral therapy.

Correct Answer

A. Stop the heparin infusion and assess for bleeding; notify the provider and prepare protamine sulfate.

Detailed Rationale

This patient’s aPTT is critically high at 118 seconds, well above the 60–80 second target. He also has early bleeding signs (IV site oozing, hematuria). The priority is patient safety. Stop the source of anticoagulation to prevent further hemorrhage. This is why stopping the infusion comes first.

After stopping the infusion, assess for bleeding head-to-toe. Check gums, nose, IV sites, surgical sites, urine, and stool. Inspect for new bruises. Perform a focused neuro exam for headache, confusion, or changes in level of consciousness. Internal and intracranial bleeding can escalate fast. Recheck vital signs for trends. A falling BP and rising HR suggest worsening blood loss.

Keep the IV line patent with normal saline (no heparin). You may need rapid access for the antidote. Notify the provider using SBAR and report the aPTT value, assessment findings, and vital signs. Prepare to give protamine sulfate, which neutralizes heparin. Dosing is based on the amount of heparin received in the last 2–3 hours. Giving it too fast can cause hypotension, so you will monitor closely.

Expect orders to hold or adjust the infusion, repeat aPTT sooner than routine, and draw a CBC to check hemoglobin, hematocrit, and platelets. Monitor for heparin-induced thrombocytopenia by watching for a sudden platelet drop (usually 30–50% from baseline). Reinforce bleeding precautions: soft toothbrush, electric razor, no IM injections, and gentle line care.

Why the Other Options Are Wrong

• B. Reduce the heparin infusion rate by 50% and recheck the aPTT in 6 hours. This is unsafe. With a dangerously high aPTT and active bleeding signs, simply cutting the rate keeps the patient exposed to excess anticoagulation. Many protocols call for holding the infusion and rechecking sooner than 6 hours.
• C. Continue the current rate and encourage oral fluids. Fluids do not neutralize heparin. Continuing the infusion increases bleeding risk. This option ignores the abnormal lab and assessment findings.
• D. Administer warfarin now to begin transition to oral therapy. Warfarin takes 2–5 days to work and does not reverse heparin. Starting warfarin now adds anticoagulation when the patient is already bleeding. Transition happens only when the patient is stable and not over-anticoagulated.

Key Takeaways

• Link labs to action. A very high aPTT plus bleeding signs means hold heparin now.
• Protamine sulfate is the reversal agent for heparin. Keep IV access patent for antidote.
• Assess for overt and covert bleeding. Do a focused neuro exam for intracranial bleed risk.
• Expect repeat aPTT and CBC. Watch platelets for possible HIT.
• Document findings, interventions, and the provider’s response. Reinforce bleeding precautions.

• On-shift mini-checklist:
• Stop heparin infusion. Keep IV with normal saline.
• Rapid bleed check: gums, nose, IV sites, urine, stool, skin, neuro status.
• Vital signs q15–30 min until stable.
• Notify provider with aPTT, assessment, and trends. Prepare protamine.
• Anticipate repeat labs and infusion adjustments. Reassess and document.

Quick Practice Extension

• A patient on IV heparin has a new platelet count drop from 240,000 to 110,000 in 48 hours. What findings increase your suspicion for HIT, and what is your next action?
• You are discharging a patient on enoxaparin. What two teaching points will you give about injection technique and signs that require calling the provider?
