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
- Triggered by sepsis, OB emergency, cancer
- Inherited factor VIII (A) or IX (B) deficiency
- X-linked recessive — males affected
Signs & symptoms
- Petechiae, purpura, mucosal bleeding
- Gingival bleeding, epistaxis
- ★Bleeding AND clotting at once
- Oozing from sites + organ ischemia
- ★Deep tissue & joint bleeds (hemarthrosis)
- Prolonged bleeding after minor injury
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
- Assess all lines/sites; watch for thrombosis
- No IM injections; apply prolonged pressure
- Assess joints for swelling, ROM loss
Treatment & meds
- Platelet transfusion
- Steroids/IVIG for ITP
- Replace factors: cryoprecipitate, FFP, platelets
- Heparin per protocol
- Factor VIII or IX concentrate
- Desmopressin (DDAVP) for mild hem. A
Patient teaching
- Soft toothbrush, electric razor; no ASA
- Avoid contact sports
- Report any new bleeding promptly
- Prophylactic factor; RICE for bleeds
- Avoid contact sports
- Avoid IM injections; genetic counseling
Red flags — escalate
- Intracranial bleed if platelets < 20,000
- Multi-organ failure from microthrombi + hemorrhage
- Hemarthrosis → joint destruction; ICH
Complications
- Severe hemorrhage; HIT → thrombosis
- High mortality; shock, organ failure
- Chronic arthropathy; transfusion infection

★ marks the fact that sets a column apart.
Clinical Pearl
Normal platelets + prolonged aPTT = hemophilia; everything abnormal + clots = DIC; low platelets alone = thrombocytopenia.
