The nurse is reviewing fetal circulation with parents after the diagnosis of a heart defect. Which statement by the nurse is correct?
"The ductus arteriosus is a shunt that allows oxygenated blood in the umbilical vein to bypass the liver and go to the heart."
"The ductus venosus is a shunt that allows oxygenated blood in the umbilical vein to bypass the liver and go to the heart."
"The foramen ovale is a shunt that allows deoxygenated blood in the umbilical vein to bypass the liver and go to the heart."
"The ductus aorta is a shunt that allows deoxygenated blood in the umbilical artery to bypass the liver and go to the heart”
The Correct Answer is B
Rationale:
A. "The ductus arteriosus is a shunt that allows oxygenated blood in the umbilical vein to bypass the liver and go to the heart.": The ductus arteriosus connects the pulmonary artery to the aorta, allowing blood to bypass the fetal lungs, not the liver.
B. "The ductus venosus is a shunt that allows oxygenated blood in the umbilical vein to bypass the liver and go to the heart.": The ductus venosus carries well-oxygenated blood from the placenta past the liver and into the inferior vena cava, directing it toward the fetal heart.
C. "The foramen ovale is a shunt that allows deoxygenated blood in the umbilical vein to bypass the liver and go to the heart.": The foramen ovale is an opening between the right and left atria that bypasses the lungs and it carries mixed oxygen blood not solely deoxygenated blood.
D. "The ductus aorta is a shunt that allows deoxygenated blood in the umbilical artery to bypass the liver and go to the heart”: There is no fetal shunt called the “ductus aorta,” and the umbilical arteries carry deoxygenated blood from the fetus to the placenta not to the heart.

Correct Answer is ["A","D","E","G"]
Explanation
Rationale:
A. Metformin twice a day, taken with food to prevent GI upset: Metformin is the first-line medication for Type 2 Diabetes and helps improve insulin sensitivity. Taking it with food reduces gastrointestinal side effects, making this a key part of treatment.
B. Long acting lantus before bed to control blood sugar overnight: While insulin may be necessary in some Type 2 Diabetes cases, especially with significant hyperglycemia, it is not typically the initial treatment for newly diagnosed adolescents. It is more common in Type 1 Diabetes or advanced Type 2.
C. Rapid Acting Insulin dosed using a sliding scale before every meal: Sliding scale insulin is generally reserved for Type 1 Diabetes or severe cases of Type 2 Diabetes with uncontrolled glucose. It is not the standard initial treatment in newly diagnosed Type 2 adolescents.
D. Consistent aerobic exercise every day with a goal of 60 minutes per day: Regular physical activity is essential in managing Type 2 Diabetes as it improves insulin sensitivity and aids in weight management.
E. Regular blood sugar monitoring throughout the day: Monitoring blood glucose levels helps track the effectiveness of treatment and guides lifestyle or medication adjustments in Type 2 Diabetes management.
F. Use of a continuous subcutaneous insulin pump to control blood sugar: Insulin pumps are typically used for Type 1 Diabetes. Their use in Type 2 Diabetes is rare and usually reserved for specific cases, not standard treatment.
G. Well balanced diet and monitoring simple sugar intake: Dietary management focusing on balanced nutrition and limiting simple sugars is fundamental in controlling Type 2 Diabetes and preventing glucose spikes.
