Can you identify the structural anomalies that make up Tetralogy of Fallot?
Pulmonic stenosis, ventricular septal defect, overriding aorta, right ventricular hypertrophy.
Aortic stenosis, atrial septal defect, overriding aorta, left ventricular hypertrophy.
Pulmonary stenosis, ventricular septal defect, aortic hypertrophy, left ventricular hypertrophy.
Aortic stenosis, ventricular septal defect, overriding aorta, right ventricular hypertrophy.
The Correct Answer is A
Choice A rationale
Tetralogy of Fallot is a congenital heart defect that includes four specific heart abnormalities: pulmonic stenosis, ventricular septal defect, overriding aorta, and right ventricular hypertrophy.
Choice B rationale
This choice incorrectly identifies aortic stenosis and atrial septal defect as components of Tetralogy of Fallot. In fact, the condition involves pulmonic stenosis and a ventricular septal defect.
Choice C rationale
This choice incorrectly identifies pulmonary stenosis and aortic hypertrophy as components of Tetralogy of Fallot. In fact, the condition involves pulmonic stenosis and right ventricular hypertrophy.
Choice D rationale
This choice incorrectly identifies aortic stenosis as a component of Tetralogy of Fallot. In fact, the condition involves pulmonic stenosis.

Correct Answer is D
Explanation
Choice A rationale
White breads and rice are not particularly high in calcium and would not be the best source of calcium for a client who does not like milk.
Choice B rationale
Meat, poultry, and fish can contain some calcium, but they are not the best source of calcium for a client who does not like milk.
Choice C rationale
Deep red or orange vegetables, while nutritious, are not particularly high in calcium.
Choice D rationale
Dark green, leafy vegetables are a good source of calcium. For a client who is in the 8th week of gestation and does not like milk, these vegetables would be a good alternative source of calcium.
Correct Answer is B
Explanation
Choice A rationale
Maternal bradycardia refers to a slower than normal heart rate in the mother. While it can affect the baby’s health, it doesn’t cause late decelerations on the fetal monitor.
Choice B rationale
Late decelerations are caused by uteroplacental insufficiency, which is a decrease in the blood flow to the placenta that reduces the amount of oxygen and nutrients transferred to the fetus. This is why the nurse would interpret late decelerations as indicating uteroplacental insufficiency.
Choice C rationale
Umbilical cord compression can cause variable decelerations, not late decelerations. Variable decelerations are abrupt decreases in the fetal heart rate, typically associated with contractions, and they vary in onset, depth, and duration.
Choice D rationale
Fetal head compression typically causes early decelerations, not late decelerations. Early decelerations are a mirror image of the contraction and are generally not a concern.
