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 A

Explanation

Step 1 is assessing heart rate. A heart rate of 130/min earns 2 points since a rate above 100/min is optimal.

Step 2 is assessing respiratory effort. A lusty cry earns 2 points as strong crying indicates good respiratory function.

Step 3 is assessing muscle tone. Flexed extremities earn 1 point since full active movement would score 2.

Step 4 is assessing reflex irritability. Grimace when suctioned earns 1 point as a vigorous response (cough, sneeze) would score 2.

Step 5 is assessing color. Acrocyanosis earns 1 point since a fully pink body scores 2.

Final answer: 7

A. Evaluate the client for signs of infection. B. Check the fetal heart rate pattern. C. Observe the color and consistency of amniotic fluid. D. Take the client's temperature.

Correct Answer is B

Explanation

Choice A rationale:

The priority nursing action after an amniotomy is to ensure the well-being of both the mother and the baby. While evaluating the client for signs of infection is important, it is not the immediate priority. Infection can be a concern after any invasive procedure, but checking the fetal heart rate pattern takes precedence to assess the baby's condition immediately after the amniotomy.

Choice B rationale:

Checking the fetal heart rate pattern is the priority because it helps to monitor the baby's well-being and detect any signs of fetal distress. Amniotomy is the artificial rupture of the amniotic membrane, and it can sometimes lead to changes in the baby's heart rate, which may indicate distress or other complications. Identifying and addressing these changes

promptly is crucial for the baby's safety.

Choice C rationale:

Observing the color and consistency of amniotic fluid is essential to assess for any abnormalities or meconium staining, which could indicate fetal distress or potential issues. However, this action should follow the immediate concern of checking the fetal heart rate pattern since fetal distress takes priority over amniotic fluid characteristics.

Choice D rationale:

Taking the client's temperature is important, but it is not the priority immediately after an amniotomy. Monitoring the client's temperature is a routine nursing action to detect any signs of infection. However, the priority in this situation is to ensure the baby's well-being through fetal heart rate assessment.
