    Radioiodine therapy is the correct answer because it involves the use of radioactive iodine to treat diseases of the thyroid gland, such as thyroid tumors. Radioactive iodine is taken orally and is absorbed by the thyroid gland. The radiation emitted by the radioactive iodine helps to destroy the abnormal thyroid tissue, reducing the size of the tumor or eliminating it altogether. This therapy is commonly used for conditions like hyperthyroidism and thyroid cancer, as it is a targeted and effective treatment option.

    Removal of plaque from an artery:

    • Endarterectomy

    • Aneurysmectomy

    • Valvuloplasty

    • Arteriography

    Correct Answer
    A. Endarterectomy
    Explanation
    Endarterectomy is the correct answer because it refers to the surgical removal of plaque from an artery. Plaque is a buildup of cholesterol, fat, and other substances that can narrow or block the arteries, leading to reduced blood flow. Endarterectomy involves making an incision in the artery, removing the plaque, and then closing the artery. This procedure helps to restore blood flow and prevent further complications such as heart attacks or strokes. Aneurysmectomy, valvuloplasty, and arteriography are not related to the removal of plaque from an artery.

    A congential defect in which the opening between the pulmonary artery and the aorta that allows blood to pass across during fetal circulation before birth, fails to close after birth is known as:

    • Tetralogy of Fallot

    • Patent ductus arteriosus

    • Atrial septal defect

    • Coarctation of the aorta

    Correct Answer
    A. Patent ductus arteriosus
    Explanation
    Patent ductus arteriosus is a congenital defect in which the opening between the pulmonary artery and the aorta, known as the ductus arteriosus, remains open after birth. Normally, the ductus arteriosus closes shortly after birth, but in the case of patent ductus arteriosus, it remains open, allowing blood to flow between the two major blood vessels. This can lead to increased blood flow to the lungs and strain on the heart. Treatment may involve medication or surgery to close the ductus arteriosus.
