    Which blood product is most appropriate for a patient with severe neutropenia and an infection unresponsive to antibiotics?

    • Fresh Frozen Plasma (FFP)

    • Cryoprecipitate

    • Platelets

    • Granulocyte concentrates

    Correct Answer
    A. Granulocyte concentrates
    Explanation
    Granulocyte concentrates are the correct choice for patients with severe neutropenia (low neutrophil count) who have an infection unresponsive to antibiotics. These concentrates provide the necessary neutrophils to help fight off bacterial and fungal infections. Fresh Frozen Plasma (FFP) and Cryoprecipitate are used for coagulation deficiencies, and Platelets are for thrombocytopenia (low platelet count), making them inappropriate for neutropenia-related infections.
