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.
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.

Correct Answer is B
Explanation
Choice A rationale
Small for gestational age (SGA) refers to newborns whose birth weight is below the 10th percentile for their gestational age.
Choice B rationale
Appropriate for gestational age (AGA) refers to newborns whose birth weight is between the 10th and 90th percentiles for their gestational age. A newborn weighing 3350 g at 39 weeks gestation falls within this range.
Choice C rationale
Low birth weight is defined as a birth weight of less than 2500 g, which does not apply to this newborn.
Choice D rationale
Large for gestational age (LGA) refers to newborns whose birth weight is above the 90th percentile for their gestational age.
Correct Answer is ["A","D","E","F"]
Explanation
Choice A rationale
Bottles can be put in the dishwasher, boiled, or cleaned with hot soapy water to ensure they are thoroughly sanitized and safe for the infant.
Choice B rationale
Holding the baby in a supine position during feedings is incorrect because it increases the risk of aspiration. The baby should be held in a semi-upright position.
Choice C rationale
Only burping the baby after they have finished the entire feeding is incorrect because it can lead to discomfort and gas buildup. The baby should be burped during and after feedings.
Choice D rationale
Always holding the bottle while feeding and not propping the bottle is correct as it prevents choking and ensures the baby is feeding safely.
Choice E rationale
Keeping the nipple full of formula throughout the feeding is correct as it prevents the baby from swallowing air, which can cause gas and discomfort.
Choice F rationale
Prepared formula can be kept in the refrigerator for 48 hours, ensuring it remains safe and free from bacterial growth.
