Final answer:
The nurse would most likely assess for chest pain with activity, dizziness with prolonged standing, and a thrill palpated at the base of the heart when assessing a child with aortic stenosis. The Correct Answer is Option. B.
Step-by-step explanation:
When assessing a child with aortic stenosis, the nurse would most likely assess for chest pain with activity, dizziness with prolonged standing, and a thrill palpated at the base of the heart.
Chest pain with activity can occur due to the narrowed aortic valve not allowing enough blood to flow through the heart.
Dizziness with prolonged standing may be a result of decreased blood supply to the brain.
A thrill palpated at the base of the heart can indicate turbulent blood flow caused by aortic stenosis.
