A nurse is assisting a client with breastfeeding her newborn. The nurse should explain that which of the following reflexes will initiate sucking?

The nurse should first report the client's respiratory status to the primary health care.

Choice A rationale:

Reporting the client's laboratory results to the primary health care is important, but in a newborn with respiratory distress and acidosis, addressing the respiratory status takes precedence. The priority is to ensure the newborn's respiratory stability and adequate oxygenation.

Choice B rationale:

Reporting the client's respiratory status to the primary health care is the correct action. A newborn with respiratory distress syndrome and respiratory acidosis requires immediate attention. The primary health care provider needs to be informed promptly to make decisions about further interventions and management.

Choice C rationale:

Reporting the client's brachial pulses to the primary health care is essential, but it is not the priority in this situation. The primary concern is the newborn's respiratory distress and acidosis, which needs to be addressed first.

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.
