Solution(By Examveda Team)

Poor blood clotting is associated with the deficiency of Vitamin-K.
Vitamin-K deficiency results from extremely inadequate intake, fat malabsorption, or use of coumarin anticoagulants. Deficiency is particularly common among breastfed infants. It impairs clotting. Diagnosis is suspected based on routine coagulation study findings and confirmed by response to Vitamin-K.
