A nurse is reinforcing teaching with a parent about using an iron-fortified formula to feed her newborn. Which of the following information should the nurse include in the teaching?
Iron will facilitate bone growth.
Newborns do not metabolize iron adequately.
The newborn's iron source will start to deplete.
Iron will facilitate eyesight development.
The Correct Answer is C
Choice A rationale:
Iron is crucial for the development of hemoglobin, which carries oxygen to all parts of the body, including the bones, but it does not directly facilitate bone growth.
Choice B rationale:
While newborns do metabolize iron, their iron stores are limited, and breast milk alone may not meet their iron needs.
Choice C rationale:
When educating a parent about the use of iron-fortified formula for their newborn, it is essential to convey that newborns have a limited store of iron, which begins to deplete around the age of 6 months.
Choice D rationale:
Iron facilitating eyesight development is not a relevant aspect to consider when discussing the use of iron-fortified formula for a newborn. While iron is essential for various physiological functions, it is not specifically linked to eyesight development.

Correct Answer is C
Explanation
Fetal circulation continues until after the stress of labor.
Choice A rationale:
Fetal circulation undergoes significant changes at birth. It becomes ineffective as the transition from intrauterine to extrauterine life occurs. The foramen ovale and ductus arteriosus, which allow blood to bypass certain fetal circulatory pathways, close as the baby breathes for the first time.
Choice B rationale:
Fetal circulation does not continue until red blood cells are broken down. Red blood cells in a fetus have a shorter lifespan than those in adults and are continually replaced throughout gestation. However, their breakdown is not the reason for the changes in fetal circulation.
Choice C rationale:
The correct answer. Fetal circulation continues until after the stress of labor. During labor, the baby experiences increased stress and pressure, which helps trigger various physiological changes, including the closure of specific fetal circulatory shunts.
Choice D rationale:
Fetal circulation does not continue until adulthood. As mentioned earlier, the transition from fetal to adult circulation occurs during and after birth, with the closure of specific fetal shunts and the establishment of a fully functional adult circulatory system.
Correct Answer is C
Explanation
Choice A rationale:
A respiratory rate of 22/min would be abnormally low for a newborn. The expected reference range for newborns is around 30-60 breaths per minute.
Choice B rationale:
A respiratory rate of 100/min would be abnormally high for a newborn. Such a high respiratory rate may indicate respiratory distress or other underlying issues and requires further evaluation.
Choice C rationale:
A respiratory rate of 48/min falls within the expected reference range for a newborn, which is around 30-60 breaths per minute. This rate suggests that the newborn's respiratory system is functioning within the normal range.
Choice D rationale:
A respiratory rate of 110/min would be abnormally high for a newborn. As mentioned earlier, the expected reference range for newborns is around 30-60 breaths per minute, making this rate concerning and necessitating further assessment.
