A nurse is reviewing the laboratory results of a group of clients. Which of the following laboratory findings should the nurse report to the provider?

Glucose of 6.7 mg/dl

WBC of 7000/mm3

Platelet count of 160,000/mm3

Hemoglobin of 6.2 g/dl

Answer and Explanation

The Correct Answer is D

A. Glucose of 6.7 mg/dL: Critically low; however, this is an unrealistic value because normal fasting glucose is 70-100 mg/dL. This might be a typo—if it were 6.7 mmol/L, it would be within the normal range.

B. WBC of 7000/mm³: Normal range (4,000-11,000/mm³), so no immediate concern.

C. Platelet count of 160,000/mm³: Normal range (150,000-400,000/mm³), so no immediate concern.

D. Hemoglobin of 6.2 g/dL: Normal hemoglobin levels are 13.5-17.5 g/dL (males) and 12-15.5 g/dL (females). A hemoglobin of 6.2 g/dL is critically low, indicating severe anemia, blood loss, or bone marrow suppression, which may require blood transfusion or further investigation.
