A nurse is collecting data from a newborn. Which of the following anatomical landmarks should the nurse use to measure chest circumference?
Sternal notch.
Nipple line.
Lower ribcage border.
Axillae.
The Correct Answer is B
The nurse should use the lower ribcage border to measure chest circumference.
Choice A rationale:
The sternal notch is not an appropriate landmark for measuring chest circumference. It is a notch at the top of the sternum and not indicative of chest circumference.
Choice B rationale:
When measuring the chest circumference of a newborn, the correct anatomical landmark to use is the nipple line. This method ensures that the measurement is taken at a consistent and reproducible location across different individuals, providing an accurate assessment of the chest size relative to growth and development standards. It's important to position the measuring tape at the level of the nipples, encircling the chest at its largest point, which typically aligns with the nipple line.
Choice C rationale:
The lower ribcage border is also not suitable as it may vary significantly with respiratory movements and is not a stable landmark for consistent measurements.
Choice D rationale:
The axillae (armpits) are not used as a landmark for measuring chest circumference. It is not a standardized anatomical point for this purpose.

Correct Answer is D
Explanation
Choice A rationale:
15 mL is not the correct choice because it only considers the first two feedings and does not account for the intake during the entire shift.
Choice B rationale:
30 mL is not the correct choice because it only considers the first three feedings and does not account for the intake during the entire shift.
Choice C rationale:
45 mL is not the correct choice because it only considers the first four feedings and does not account for the intake during the entire shift.
Choice D rationale:
The nurse should record 60 mL of formula as the newborn's intake for the shift. To calculate the total intake, you add the amounts from each feeding: 0.5 oz + 1 oz + 0.5 oz + 0.5 oz + 0.5 oz = 60 mL. Remember that 1 fluid ounce (oz) is approximately equal to 30 mL.
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.
