For each of the following patients, select the most likely peripheral blood finding:

1. A 63-year-old man has a CBC showing WBC count 2750/microliter, Hgb 10.0 g/dL, Hct 30.2%, MCV 94 fL, and platelet count 62,000/microliter. A posterior iliac crest bone marrow biopsy shows markedly decreased hematopoiesis along with extensive fibrosis:

2. A 26-year-old woman has Enterobacter cloacae septicemia. She develops areas of purpura on her skin. Her D-dimer test is markedly elevated. Her prothrombin time and partial thromboplastin times are increased, while her platelet count and serum fibrinogen are decreased:

3. A 15-year-old boy has a positive monospot test. He has a mild pharyngitis followed by generalized lymphadenopathy, malaise, and mild scleral icterus. His spleen tip is also palpable. He recovers in a month:

4. A 40-year-old man has undergone splenectomy following an auto accident. He now has a CBC that shows WBC count 8120/microliter, Hgb 14.3 g/dL, Hct 42.5%, MCV 90 fL, and platelet count 187,000/microliter:

5. A 29-year-old woman who doesn't like to eat vegetables has a serum folate of 1.2 ng/mL with vitamin B12 of 405 pg/mL. She has a CBC that shows WBC count 6870/microliter, Hgb 11.8 g/dL, Hct 36.2%, MCV 104 fL, and platelet count 276,000/microliter:
