Choice A reason:

While hypoglycemia (glucose <45 mg/dL) is concerning,58 mg/dLis within acceptable ranges for many institutions, especially in asymptomatic newborns. Monitoring is required, but it is less urgent than respiratory distress.

Choice B reason:

Respiratory rate of 78 breaths per minute is also within the normal range for a newborn, which typically ranges from 30 to 60 breaths per minute. Though respiratory rate is essential to assess, it does not take priority over other critical issues.

Choice C reason:

Newborns typically have a normal respiratory rate of30-60 breaths/minute. A rate of78indicatessignificant tachypnea, which could signal respiratory distress (e.g., transient tachypnea of the newborn, infection, or respiratory distress syndrome). Rapid breathing can lead to fatigue, hypoxia, or respiratory failure if not promptly addressed.

Choice D reason:

A glucose reading of 58 mg/dL is concerning in a newborn. Hypoglycemia (low blood glucose) can lead to serious complications if not promptly addressed. Newborns are particularly susceptible to hypoglycemia, and it requires immediate assessment and intervention.

Choice A reason:

A prolapsed umbilical cord occurs when the cord slips ahead of the presenting fetal part, potentially leading to cord compression and compromised fetal oxygenation. However, hypertonic contractions do not directly cause a prolapsed cord. Instead, factors such as premature rupture of membranes, abnormal fetal positioning, or excessive amniotic fluid (polyhydramnios) are more likely contributors to cord prolapse. Hypertonic contractions primarily affect uteroplacental circulation rather than fetal positioning.

Choice B reason:

One side effect of oxytocin stimulation is hypertonic contractions. This can be detrimental to the fetus because it produces a prolapsed cord. This is incorrect because a prolapsed cord is not caused by hypertonic contractions, but by other factors such as a low-lying placenta, a premature rupture of membranes, a small or preterm fetus, or an abnormal presentation. A prolapsed cord occurs when the umbilical cord slips through the cervix and into the vagina before or during delivery. This can compress the cord and cut off the blood supply to the fetus, resulting in fetal bradycardia and possible death.

Choice C reason:

One side effect of oxytocin stimulation is hypertonic contractions. This can be detrimental to the fetus because it increases maternal renal blood flow. This is incorrect because hypertonic contractions do not affect maternal renal blood flow directly. Maternal renal blood flow is influenced by factors such as maternal blood pressure, hydration, cardiac output, and renal function. Hypertonic contractions may cause maternal dehydration, which can reduce renal blood flow, but this is not a direct effect of oxytocin stimulation.

Choice D reason:

Hypertonic contractions reduce placental blood flow by limiting the relaxation phase between contractions. Normally, uterine contractions intermittently compress the spiral arteries supplying the placenta, but prolonged or excessively frequent contractions prevent adequate placental perfusion. This can lead to fetal hypoxia, acidosis, and distress, making it the most detrimental effect of oxytocin-induced hypertonic contractions.
