The neonatal nurse assesses newborns for iron deficiency anemia. Which newborn is at highest risk for this disorder?

A premature newborn

A postterm newborn

A newborn born to a diabetic mother

A term newborn with jaundice

Answer and Explanation

The Correct Answer is A

A. A premature newborn: Premature infants are at higher risk for iron deficiency anemia because they have lower iron stores at birth compared to full-term infants. Additionally, premature infants may not have had sufficient time in utero to accumulate adequate iron stores from maternal

transfusions.

B. A postterm newborn: Postterm infants, born after 42 weeks of gestation, are not typically at increased risk for iron deficiency anemia solely based on gestational age.

C. A newborn born to a diabetic mother: While infants born to diabetic mothers may have other health risks, they are not inherently at higher risk for iron deficiency anemia unless there are other complicating factors such as prematurity or inadequate iron intake.

D. A term newborn with jaundicE. Jaundice in a term newborn is typically caused by elevated

levels of bilirubin and is not directly associated with an increased risk of iron deficiency anemia.

Correct Answer is A

Explanation

A. Most infants double their birth weight by 5 to 6 months of age.

B. Doubling of birth weight by 3 months is less common and may indicate overfeeding or an error in measurement.

C. By 9 months, infants have usually surpassed the milestone of doubling their birth weight.

D. At 12 months, infants typically triple their birth weight, so this is beyond the timeframe for doubling birth weight

A. Increased intracranial pressure B. Dehydration C. Overhydration D. These are normal findings

Correct Answer is D

Explanation

A. Increased intracranial pressurE. Pulsation and bulging of the fontanel may be signs of

increased intracranial pressure in infants. However, it is important to differentiate between normal fontanel characteristics and abnormal signs of elevated intracranial pressure. In this case, the pulsation and bulging are likely normal responses to crying and changes in intracranial pressure during the newborn period.

B. Dehydration: Dehydration typically presents with sunken fontanels rather than pulsation and bulging. Dehydration is a serious condition that requires prompt assessment and intervention, but it is not indicated by the findings described in the scenario.

C. Overhydration: Overhydration is not typically associated with pulsation and bulging of the fontanel. Overhydration may lead to fluid overload and edema but does not directly affect fontanel characteristics.

D. These are normal findings: Pulsation and brief bulging of the fontanel in response to crying are considered normal findings in newborns. Fontanels allow for the flexibility of the skull bones during childbirth and provide space for brain growth during infancy. Pulsation and bulging may occur temporarily during crying or changes in intracranial pressure and are not necessarily

indicative of pathology.
