Which statement about fetal circulation is true?

Fetal circulation is no longer effective at birth.

Fetal circulation continues until red blood cells are broken down.

Fetal circulation continues until after the stress of labor.

Fetal circulation continues until adulthood.

Answer and Explanation

The Correct Answer is C

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.

Correct Answer is C

Explanation

Choice A rationale:

Activating respiratory arrest procedures is not necessary in this situation. The newborn's respiratory rate, although slightly elevated, does not indicate respiratory arrest. Instead, such procedures are reserved for situations where the newborn has stopped breathing or is in acute respiratory distress.

Choice B rationale:

Requesting an order for supplemental oxygen may be premature. The newborn's respiration rate of 44/min, although shallow with periods of apnea, is still within the normal range for a newborn. Providing supplemental oxygen should be considered when the newborn is showing signs of significant respiratory distress or if oxygen saturation levels are low.

Choice C rationale:

The most appropriate action in this scenario is to continue routine monitoring of the newborn's respiratory rate and overall condition. Newborns often exhibit irregular breathing patterns, including periods of apnea, especially in the first few hours after birth. As long as the newborn's color, heart rate, and overall appearance are stable, routine monitoring is appropriate.

Choice D rationale:

There is no need to report the observation to the charge nurse immediately, as the newborn's respiratory rate and pattern fall within the expected range for a 12-hour-old newborn.

Reporting should be considered when there are significant deviations from the norm or if the newborn's condition deteriorates.

A. Notifying the provider immediately. B. Pressing on the bladder to prevent urine retention. C. Administering IV fluid. D. Documenting and continuing monitoring.

Correct Answer is D

Explanation

Choice A rationale:

Notifying the provider immediately may be an appropriate action in certain urgent situations. However, for a newborn who has not voided for the first time yet, it is not an immediate emergency. The priority is to assess the newborn's condition further before notifying the provider.

Choice B rationale:

Pressing on the bladder to prevent urine retention is not a recommended action. Applying pressure on the newborn's bladder can be harmful and is not a standard nursing practice.

Choice C rationale:

Administering IV fluid is not the priority action for a newborn who has not voided. Newborns usually receive sufficient hydration from breastfeeding or formula feeding, and administering IV fluid without proper indication can lead to potential complications.

Choice D rationale:

Documenting and continuing monitoring is the correct priority action in this situation. Newborns often take some time to pass their first urine, and it is considered normal for them to have delayed voiding within the first 24 hours after birth. The nurse should document the absence of voiding and monitor the newborn for any signs of distress or abnormalities. If the newborn's condition worsens or if there are other concerning symptoms, then notifying the provider may be necessary.
