Thrombocytosis
Structured condition card with NCLEX priority cues and nursing action focus.
Hematologic / Immunemedium priorityneeds review
Thrombocytosis
Also testable as: High platelets, Essential thrombocythemia, Reactive thrombocytosis
Etiology / Pathophysiology
- Inflammation, infection, iron deficiency, splenectomy, malignancy, or marrow disorder can increase platelet count.
- High platelet count can increase clot risk, while abnormal platelets may also contribute to bleeding risk.
Medications
| Class | Why it matters |
|---|---|
| Antiplatelets | May be ordered in selected thrombotic-risk plans. |
Nursing actions
- Assess for DVT/PE/stroke symptoms, chest pain, headache, vision changes, and bleeding.
- Trend platelet count with clinical context and iron/inflammation findings.
- Teach urgent reporting of unilateral swelling, shortness of breath, neuro deficits, or unusual bleeding.
Complications
- Thrombosis
- Stroke
- Pulmonary embolism
- Bleeding in selected disorders
NCLEX cues
- High platelet count does not always mean better clotting.
- Clot symptoms outrank routine lab review.
Memory hooks
- Too many platelets can clot or malfunction.
Labs / Diagnostics
- CBC
- Iron studies
- Inflammatory markers
- Peripheral smear or marrow testing when ordered
Review notes
- Supplemental wife-requested study card. Use for NCLEX review only and verify against school materials, ATI/NCLEX review sources, current orders, and facility policy.
