Now I have all the information needed to answer this question comprehensively. Here's the full analysis:

Question 43 — Answer: A. IVIG

Clinical Diagnosis: Acute ITP (Immune Thrombocytopenic Purpura)

The scenario is a textbook presentation:

6-year-old girl (typical age: 2–6 years)
Multiple ecchymoses + epistaxis (mucocutaneous bleeding)
Preceding URTI 2 weeks ago (viral prodrome within 3 weeks is classic)
FBC: Normal WBC, normal Hb → isolated thrombocytopenia (platelet count is low — cut off in image, but clearly symptomatic)

The normal WBC and Hb rule out leukemia/aplastic anemia, confirming ITP.

Why IVIG is the Correct Answer

According to Tintinalli's Emergency Medicine:

"IV immunoglobulin is superior to steroids in improving platelet numbers for immune thrombocytopenia patients."

And from Rosen's Emergency Medicine:

"IVIG can be considered if there is a need for a more rapid correction of the platelet count."

This child has active bleeding (epistaxis + ecchymoses), which means a rapid rise in platelet count is needed — making IVIG the most appropriate immediate option.

IVIG dose: 1 g/kg/day
Mechanism: saturates Fc receptors on splenic macrophages → reduces platelet destruction → faster platelet recovery

Why the Other Options Are Less Optimal

Option	Reasoning
B. IV Methylprednisolone	Less rapid than IVIG; used when faster response is needed alongside IVIG, but alone it's slower
C. Monitor platelet count	Appropriate only for mild ITP with skin manifestations only and platelet count not critically low; not when active bleeding (epistaxis) is present
D. Oral prednisolone	Slower onset; also requires leukemia/aplastic anemia to be excluded before starting; less effective than IVIG
E. Platelet transfusion	Rapidly consumed by circulating antiplatelet antibodies; reserved for life-threatening hemorrhage only

Key Teaching Point

Mild ITP (only skin findings, stable): watchful waiting / monitoring platelet count is acceptable in children
Symptomatic ITP with active bleeding (epistaxis, mucosal): IVIG is the treatment of choice for fastest platelet response
Steroids (oral prednisolone) are an alternative but must exclude leukemia first — in this case no bone marrow biopsy has been done
IVIG is superior to steroids in raising platelet count more rapidly

Answer: A — IVIG ✓
