Answer to Question 1

ANS: C
Segmented neutrophils contain many small pink-lilac granules in their cytoplasm. The nucleus is characterized by clumped chromatin, usually with segments, although it may appear twisted or folded. The background color of the cytoplasm is colorless; no ribonucleic acid (RNA) is present (and so no basophilia).

Answer to Question 2

ANS: D
At least three systems exist for morphologic identification of band neutrophils. They vary with the shape of the nucleus. Hematology analyzers that perform automated differentials classify them (bands) with polymorphonuclear (segmented) neutrophils; therefore many laboratories now use the same criteria when identifying cells using the microscope.
