Solution:The child has bloody diarrhea, sunken eyes, and skin pinch goes back slowly, indicating some dehydration, which requires Plan B management under the IMNCI guidelines:
A. Plan B: Rehydration with ORS at 75 mL/kg over 4 hours is recommended for children with some dehydration.
D. Zinc: Should be given as an adjunct therapу in all children with diarrhea, including bloody diarrhea, to reduce severity and recurrence.
B. Antibiotics should be started in cases of bloody diarrhea, as it's likely to be dysentery (e.g., Shigella), so this option is incorrect.
C. Reassessment after 30 minutes is done, but not all such children are sent home immediately; some may require further observation or treatment.
Hence, A and D only are correct.
