A hemoglobin value of 14.5 g/dL would indicate anemia in which of the following patients?

The correct choice is based on understanding normal hemoglobin values across different age and gender groups. In adults, normal hemoglobin levels typically range from about 13.5 to 17.5 g/dL for men and 12.0 to 15.5 g/dL for women. For children, values vary based on their age, and in the case of a 10-year-old girl, normal levels usually fall between 11.5 to 15.5 g/dL.

In the context of a newborn boy, the normal ranges for hemoglobin are significantly higher, usually around 14 to 24 g/dL shortly after birth, and can decrease as the infant matures. Therefore, a hemoglobin level of 14.5 g/dL in a newborn would be on the lower end or below normal, indicating that this individual could be classified as anemic.

Overall, understanding the normal hemoglobin ranges is crucial for diagnosing anemia appropriately based on the patient's demographic factors such as age and gender. This knowledge helps clinicians determine when a value falls outside the expected range for a specific population group, as seen in this scenario with the newborn boy.
