A nurse is collecting data from a newborn 1 hr after delivery. Which of the following respiratory rates is within the expected reference range for a newborn?

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.

Fetal circulation continues until after the stress of labor.

Choice A rationale:

Fetal circulation undergoes significant changes at birth. It becomes ineffective as the transition from intrauterine to extrauterine life occurs. The foramen ovale and ductus arteriosus, which allow blood to bypass certain fetal circulatory pathways, close as the baby breathes for the first time.

Choice B rationale:

Fetal circulation does not continue until red blood cells are broken down. Red blood cells in a fetus have a shorter lifespan than those in adults and are continually replaced throughout gestation. However, their breakdown is not the reason for the changes in fetal circulation.

Choice C rationale:

The correct answer. Fetal circulation continues until after the stress of labor. During labor, the baby experiences increased stress and pressure, which helps trigger various physiological changes, including the closure of specific fetal circulatory shunts.

Choice D rationale:

Fetal circulation does not continue until adulthood. As mentioned earlier, the transition from fetal to adult circulation occurs during and after birth, with the closure of specific fetal shunts and the establishment of a fully functional adult circulatory system.
