A nurse is collecting data from a newborn. Which of the following anatomical landmarks should the nurse use to measure chest circumference?

Choice A rationale:

Reporting the client's weight to the provider is not a priority in this situation. While weight is important, the immediate concern is the newborn's respiratory distress and the acidosis indicated by the blood gases.

Choice B rationale:

Selecting diagnostic studies for the primary health care is not the nurse's role. The primary health care provider will determine which diagnostic studies are needed based on the newborn's clinical presentation and assessment findings.

Choice C rationale:

Checking brachial pulses for the client's respiratory status is the appropriate action. In a newborn with respiratory distress, assessing peripheral perfusion, including brachial pulses, is crucial to monitor the circulation and oxygenation of tissues.

Choice A rationale:

Iron will facilitate bone growth. This statement is not accurate in the context of feeding a newborn with iron-fortified formula. While iron is essential for overall growth and development, its primary role is not specifically related to bone growth. Instead, it plays a crucial role in the production of hemoglobin, which helps carry oxygen in the blood.

Choice B rationale:

Newborns do not metabolize iron adequately. This statement is the correct choice. Newborns have limited iron stores that are obtained from their mothers during pregnancy. As they grow, their iron requirements increase, but their ability to metabolize iron is not fully developed at

birth. Hence, iron-fortified formula is recommended to provide the necessary iron for the newborn's healthy development.

Choice C rationale:

The newborn's iron source will start to deplete. This statement is not accurate in the context of iron-fortified formula feeding. The newborn's initial iron source is the iron stores passed on by the mother during pregnancy. However, the iron-fortified formula is designed to supplement and fulfill the baby's iron needs, preventing depletion of iron stores.

Choice D rationale:

Iron will facilitate eyesight development. This statement is not entirely accurate. While iron is important for many bodily functions, including eye health, it is not specifically responsible for eyesight development in newborns. Visual development in newborns is influenced by various factors, but iron intake through formula feeding directly impacting eyesight is not a primary concern.
