Lecture Notes on Blood Thinners

Introduction

  • Presenter: Nurse Mike from SimpleNursing.com
  • Topic: Blood Thinners
  • Promotion of NCLEX app with practice questions and detailed video rationales.

Types of Blood Thinners

  • Small: Anti-platelets like Aspirin and Clopidogrel (Watergun)
  • Medium: Anticoagulants like Heparin and Warfarin (Bazooka)
  • Large: Thrombolytics like TPA and Altaplace (Atomic Bomb)

Anti-platelets: Aspirin and Clopidogrel

Indication

  • Clot prophylaxis (prevention)
  • Used in:
    • Heart and brain clots (MI, CVA prevention)
    • Narrowed arteries (ACS, TIA, PAD)
    • Post-stent or bypass (prevention of reocclusion)
    • Post-PCI (Percutaneous Coronary Intervention)

Mechanism of Action

  • Prevent platelet aggregation (anti-clot)

Key Points Before Administration

  • Assess Hemoglobin:
    • Less than 7: High bleed risk
  • Assess Platelets:
    • Normal range: 150 – 400
    • Less than 150: Notify HCP
    • Less than 50: High bleed risk (thrombocytopenia)
  • Priority action for low platelet count (<75,000 or <40,000):
    • Hold drug, question prescription, notify HCP

Aspirin Specific Notes

  • Toxicity:
    • Signs: Tinnitus (ear ringing), hyperventilation
    • Treatment: Activated charcoal (blocks absorption)
  • Contraindication:
    • Patients with hypoprothrombinemia (low clotting factors)
  • Exam Tips:
    • Priority assessment for long-term use: Tinnitus
    • Tachycardia and hypotension not toxicity signs (could indicate bleed)

Glycoprotein or GP Receptor Inhibitors

  • Example: L-cyxamab
  • Use: Post-cardiac procedures (heart cath, coronary stent)
  • Adverse Effects:
    • Severe thrombocytopenia and bleeding

Nursing Care

  • Assessment:
    • Hemoglobin below 7: High risk
    • Platelets below 150: Caution
    • Less than 50: High risk (question prescriptions)
  • Monitor for bleeding

Conclusion

  • Encourage accessing full video and quiz bank
  • Acknowledgement of the team of experts
  • Promotion of YouTube channel subscription
