Sample Practice Questions (5)
1. A CBC report shows: WBC 15,200/mcL, RBC 4.8M/mcL, Hgb 14.2 g/dL, Hct 43%, Platelets 210,000/mcL. The differential shows neutrophils 82%, bands 8%, lymphocytes 7%, monocytes 3%. These results are MOST consistent with:
- Acute bacterial infection with a left shift
- Viral infection with lymphocytosis
- Iron-deficiency anemia
- Allergic reaction with eosinophilia
2. A CBC differential shows: neutrophils 85% (reference 50-70%), lymphocytes 8% (reference 20-40%), monocytes 5%, eosinophils 1%, basophils 1%. This pattern is described as neutrophilia with lymphopenia and is MOST commonly seen in:
- Acute bacterial infection
- Viral infection
- Parasitic infection
- Allergic reaction
3. The normal fasting blood glucose range for an adult is:
- 70 to 100 mg/dL
- 100 to 140 mg/dL
- 40 to 60 mg/dL
- 140 to 200 mg/dL
