Bleeding vs Clotting Disorders: Thrombocytopenia vs DIC vs Hemophilia
All three disorders cause bleeding, but the lab panels look completely different. Pick the wrong pattern on the NCLEX and you'll choose platelet transfusion when the patient needs cryoprecipitate — or miss that clotting and bleeding are happening simultaneously in DIC.

Dimension
Thrombocytopenia
DIC
Hemophilia
Pathophysiology & risk
- ↓ platelet production or ↑ destruction
- ITP, HIT, chemo, hypersplenism
- Consumes platelets + clotting factors
- Triggers: sepsis, OB emergency, cancer
- Factor VIII (A) or IX (B) deficiency
- X-linked recessive — males affected
Signs & symptoms
- Petechiae & purpura
- Gingival bleeding, epistaxis
- ★Bleeding AND clotting at once
- Oozing from IV & puncture sites
- Petechiae & purpura
- ★Joint bleeds (hemarthrosis)
- Deep muscle hematomas
Diagnostics & labs
- Isolated ↓ platelets (< 150,000)
- PT, aPTT, fibrinogen, D-dimer normal
- ↑ PT/aPTT, ↓ fibrinogen, ↓ platelets
- ↑ D-dimer (fibrinolysis)
- ★Prolonged aPTT only
- Normal PT, platelets, fibrinogen
Nursing priorities
- Bleeding precautions
- Avoid ASA/NSAIDs
- ★If HIT: stop ALL heparin
- Treat the underlying cause
- Watch for clots: cool, pale limbs
- Bleeding precautions
- Avoid ASA/NSAIDs
- Bleeding precautions
- Avoid ASA/NSAIDs
- Assess joints: swelling, ↓ ROM
Treatment & meds
- Platelet transfusion
- Steroids/IVIG for ITP
- FFP + cryoprecipitate
- Heparin only if clotting dominates
- Platelet transfusion
- Factor VIII or IX concentrate
- DDAVP for mild hemophilia A
Patient teaching
- Soft toothbrush, electric razor
- Avoid contact sports
- Report new bleeding or clot signs
- Home factor infusion
- RICE for joint bleeds
- Avoid contact sports
- Genetic counseling
- Soft toothbrush, electric razor
Red flags — escalate
- Intracranial bleed if platelets < 20,000
- Multi-organ failure (microthrombi)
- Acute hemarthrosis: pain, swelling
- Head injury: give factor first
Complications
- Severe hemorrhage
- HIT: paradoxical thrombosis
- High mortality
- Shock, organ failure
- Severe hemorrhage
- Chronic arthropathy
- Inhibitor antibodies to factor
- Severe hemorrhage

Clinical Pearl
Normal platelets + prolonged aPTT = hemophilia; everything abnormal + clots = DIC; low platelets alone = thrombocytopenia.

- TopicDIC — Disseminated Intravascular CoagulationThe patient is clotting and bleeding at the same time — that paradox is what makes DIC lethal and what makes it a recurring NCLEX trap.
- TopicHemophiliaA child bleeds into the joints after a minor bump — the platelet count is perfectly normal. The problem isn't the platelets; it's what happens after the initial plug forms.
