When should a nurse screen for anemia in a child?

• A. Routine screening around 9-12 months or earlier if risk factors exist
• B. Only during adolescence
• C. Only if the child complains of fatigue
• D. Anemia screening is not necessary in children

Answer: (A)

Screening for anemia in young children is done routinely around 9 to 12 months, with earlier testing if risk factors exist. This timing catches iron deficiency after the infant has transitioned to solid foods and iron needs have increased, but before iron deficiency can impact growth and development. Iron deficiency is relatively common in early childhood, and many affected children may not show clear symptoms, so a routine test helps identify a problem early. Testing is typically done with a simple blood test to measure hemoglobin or hematocrit levels.

Risk factors that would prompt earlier screening include prematurity or low birth weight, a lifestyle or diet that limits iron intake (for example, exclusive breastfeeding beyond 6 months without iron supplementation or a high intake of cow’s milk before 12 months), and any conditions that affect iron absorption or increase iron needs.

Choosing to screen only during adolescence or only when a child reports fatigue isn’t adequate because anemia can be present without symptoms in young children, and delaying detection can miss a window where intervention prevents developmental impact. Additionally, saying screening isn’t necessary ignores the substantial role early identification plays in guiding dietary changes or supplementation to support healthy growth.
