A nurse is caring for a newborn. How many blood vessels should the nurse expect to observe in the newborn's umbilical cord?

Two arteries and two veins.

One artery and one vein.

Two arteries and one vein.

Two veins and one artery.

Answer and Explanation

The Correct Answer is C

Choice A rationale:

The umbilical cord typically contains two arteries and one vein. Arteries carry oxygen-depleted blood and waste products from the fetus to the placenta for removal, while the vein carries oxygenated blood and nutrients from the placenta to the fetus. This arrangement is essential for maintaining proper fetal circulation during pregnancy.

Choice B rationale:

This choice is incorrect because the umbilical cord usually contains two arteries and one vein, not just one artery and one vein. Having only one artery could indicate a potential vascular abnormality or congenital issue that may require further investigation or medical attention.

Choice C rationale:

This is the correct answer. The umbilical cord usually contains two arteries and one vein. The presence of two arteries allows for the efficient removal of waste products and carbon dioxide from the fetus, while the single vein delivers essential nutrients and oxygen to support the baby's growth and development.

Choice D rationale:

This choice is incorrect as it states two veins and one artery, which is not the typical configuration of blood vessels in the umbilical cord. Having two veins and one artery would disrupt fetal circulation and hinder proper nutrient and waste exchange between the fetus and the placenta.

Correct Answer is D

Explanation

The correct answer is choice D. Uterine contraction lasting 2 min.

Choice A rationale:

Early decelerations in the FHR are usually not a concern during the second stage of labor. They are a normal physiological response to the compression of the fetal head during contractions and are generally considered benign.

Choice B rationale:

Pelvic pressure with contractions is a normal finding during the second stage of labor as the baby descends into the pelvis. It does not typically require reporting to the provider unless it is associated with other concerning symptoms.

Choice C rationale:

A bloody show from the vagina is a common and expected finding during the second stage of labor. It indicates that the cervix is dilating and effacing, which is a normal part of the labor process.

Choice D rationale:

A uterine contraction lasting 2 minutes is abnormal and could indicate uterine tachysystole, which can lead to fetal distress due to reduced uterine blood flow and oxygen to the fetus. This finding should be reported to the provider immediately.

A. Fetal heart rate 100/min for a 10-min period. B. Contraction resting period 35 seconds. C. Contraction lasting 85 seconds. D. Four contractions in a 10-min period.

Correct Answer is C

Explanation

Choice A rationale:

A fetal heart rate of 100/min for a 10-minute period is considered within the normal range. The normal fetal heart rate can range from 110 to 160 beats per minute, and a rate of 100 is not concerning.

Choice B rationale:

The resting period of a contraction refers to the time between contractions when the uterus is relaxed. A resting period of 35 seconds is also considered normal. In labor, the resting period between contractions allows the placenta to receive oxygen and nutrients, and 35 seconds is a rationaleable duration.

Choice C rationale:

A contraction lasting 85 seconds is abnormal and should be reported to the provider. Normally, contractions last around 60-90 seconds, but an 85-second contraction may indicate uterine hyperactivity or other issues that could potentially affect the well-being of both the mother and the baby.

Choice D rationale:

Having four contractions in a 10-minute period is considered normal during labor. In fact, an average pattern includes 3-5 contractions within a 10-minute window, so this finding is not a cause for concern.
