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.
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 C
Explanation
Choice A rationale :
Hypercalcemia - The nurse does not need to monitor for hypercalcemia in this scenario. Hypercalcemia refers to high levels of calcium in the blood, and it is not directly related to the newborn's weight or the mother's diabetes mellitus.
Choice B rationale
Hypobilirubinemia - Hypobilirubinemia is low levels of bilirubin in the blood and is not a major concern for a newborn's weight or the mother's diabetes mellitus. Although jaundice (high bilirubin levels) can be a concern in newborns, it is not the focus in this case.
Choice C rationale
Hypoglycemia - This is the correct choice. Newborns of diabetic mothers are at risk of developing hypoglycemia, which is low blood sugar levels. The baby receives excess glucose from the mother during pregnancy, and after birth, insulin production may be higher than needed, leading to low blood sugar levels. Monitoring for hypoglycemia is crucial to prevent potential complications.
Choice D rationale
Decreased RBC - The nurse does not need to monitor for decreased red blood cells (RBC) specifically related to the newborn's weight or the mother's diabetes mellitus. Monitoring RBC levels is important for other conditions, but it is not the primary concern in this case.
Correct Answer is ["A","D","E"]
Explanation
Dysuria - Dysuria refers to painful or difficult urination. In a client with a urinary tract infection (UTI), this symptom is commonly present. The rationale behind this finding is that the infection irritates the urinary tract, causing discomfort and pain during urination. The client may experience a burning sensation or pressure while passing urine.
Choice D rationale
Hematuria - Hematuria refers to the presence of blood in the urine. In the case of a UTI, inflammation of the urinary tract can lead to tiny blood vessels rupturing, resulting in blood in the urine. This can cause the urine to appear pink, red, or brownish.
Choice E rationale:
Urinary frequency - Urinary frequency is another common symptom of a UTI. The infection can irritate the bladder lining, leading to an increased urge to urinate even when the bladder is not full. The client may feel the need to urinate frequently throughout the day and night.
Choice B rationale
Dependent edema - Dependent edema is not typically associated with a urinary tract infection. Edema is the accumulation of fluid in tissues, often causing swelling in the lower extremities due to gravity (dependent). This symptom is more commonly related to issues such as heart, kidney, or liver problems.
Choice C rationale
Polyuria - Polyuria refers to excessive urination, usually producing abnormally large volumes of urine. While frequent urination is a symptom of a UTI, polyuria, in this context, is not accurate. UTIs tend to cause frequent but smaller volumes of urine due to the irritation and inflammation of the bladder.
