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

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.

Choice A rationale:

The nurse should include teaching the client to perform daily fetal movement counts because it is an essential aspect of monitoring the baby's well-being and assessing fetal distress. Fetal movement counts help the client become familiar with their baby's normal patterns of movement, allowing them to detect any changes or decreased movements promptly. This can be crucial in identifying potential issues with the baby's health and seeking timely medical attention.

Choice B rationale:

The nurse should not advise limiting fluid intake to 1,000 mL/day for a client with mild preeclampsia. Adequate hydration is important during pregnancy, and excessive fluid restriction can lead to dehydration, which is harmful to both the mother and the baby. Preeclampsia can cause fluid retention and high blood pressure, but complete fluid restriction is not the appropriate approach for managing the condition.

Choice C rationale:

The nurse should not suggest limiting sodium intake to 2,000 mg/day for a client with mild preeclampsia. While reducing sodium intake can be beneficial for some individuals with hypertension, it is not the primary focus in managing mild preeclampsia. The mainstay of treatment for mild preeclampsia typically involves close monitoring, rest, and potential medications to control blood pressure if necessary.

Choice D rationale:

The nurse should not recommend that the client rest in bed in the supine position. During pregnancy, especially with preeclampsia, lying flat on the back (supine position) can lead to a condition called supine hypotensive syndrome. This occurs when the weight of the uterus presses on the vena cava, reducing blood flow back to the heart and potentially causing a drop in blood pressure and decreased blood flow to the baby.
