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.

Answer and Explanation

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 ["C","E"]

Explanation

Choice A rationale:

Washing the penis with warm water and mild soap each day is not an appropriate statement regarding circumcision care with a Plastibell device. Keeping the area clean is essential, but soap may irritate the wound, and frequent washing can disrupt the healing process.

Choice B rationale:

Ensuring a loose diaper in the front is not directly related to circumcision care with a Plastibell device. It may be relevant for comfort, but it does not address specific care for the circumcision site.

Choice C rationale:

This is a correct statement indicating understanding of circumcision care with the Plastibell device. The plastic ring is expected to fall off on its own within a week, and this is a normal part of the healing process.

Choice D rationale:

Applying petroleum jelly to the penis during diaper changes is not recommended for circumcision care with a Plastibell device. The petroleum jelly can interfere with wound healing and should be avoided.

Choice E rationale:

This is also a correct statement indicating understanding of circumcision care. If bleeding occurs after the Plastibell has fallen off, it could be a sign of a complication, and the doctor should be notified promptly.

A. The newborn's temperature control mechanism is immature. B. Heat increases the flow of oxygen to the newborn's extremities. C. The newborn has a small body surface for his weight. D. Heat facilitates the drainage of mucus for a premature newborn.

Correct Answer is A

Explanation

Choice A rationale:

Placing the newborn in an incubator is essential because the newborn's temperature control mechanism is immature. Premature infants have an underdeveloped thermoregulatory system, making them susceptible to heat loss and cold stress. An incubator provides a controlled, warm environment to maintain the newborn's body temperature within the normal range (around 36.5°C to 37.5°C or 97.7°F to 99.5°F).

Choice B rationale:

Heat increasing the flow of oxygen to the newborn's extremities is not a valid reason for placing the newborn in an incubator. Oxygenation is primarily influenced by respiratory and circulatory mechanisms, not external heat.

Choice C rationale:

The newborn's small body surface area for his weight is not directly related to the need for an incubator. Premature infants have a higher surface area to weight ratio, making them more prone to heat loss, but this is not the primary reason for using an incubator.

Choice D rationale:

Heat facilitating the drainage of mucus is not a reason for placing the newborn in an incubator. Proper positioning and suctioning are used to manage mucus in premature infants, but incubators are primarily for temperature regulation.
