A nurse is completing the admission assessment of a newborn.
Which of the following anatomical landmarks should the nurse use when measuring the newborn’s chest circumference?

Xiphoid process.

Fifth intercostal space.

Sternal notch.

Nipple line.

Answer and Explanation

The Correct Answer is D

Choice A rationale

The xiphoid process is not the correct anatomical landmark for measuring chest circumference in newborns. It is located at the lower end of the sternum and does not provide a consistent measurement point.

Choice B rationale

The fifth intercostal space is not used for measuring chest circumference in newborns. This space is located between the ribs and is not a reliable landmark for consistent measurements.

Choice C rationale

The sternal notch is not the correct landmark for measuring chest circumference. It is located at the top of the sternum and does not provide a consistent measurement point.

Choice D rationale

The nipple line is the correct anatomical landmark for measuring chest circumference in newborns. This method ensures that the measurement is taken at a consistent and reproducible location, providing an accurate assessment of the chest size relative to growth and development standards.
