Explanation
Choice C is correct. Trisomy 21, or Down's Syndrome, is commonly associated with an atrioventricular canal. Infants with trisomy 21 also commonly present with an atrial septal defect (ASD) or ventricular septal defect (VSD).
Choice A is incorrect. Trisomy 18, or Edwards syndrome, is commonly associated with a VSD or hypoplastic left heart syndrome (HLHS), but not an atrioventricular canal.
Choice B is incorrect. Turner syndrome is commonly associated with several different heart defects including a VSD, coarctation of the aorta (COA), aortic stenosis, and HLHS, but not an atrioventricular canal.
Choice D is incorrect. DiGeorge Syndrome is commonly associated with an interrupted aortic arch, but not an atrioventricular canal.

Additional Info
✓ Atrioventricular canal is a congenital heart defect characterized by abnormalities in the structures that separate the atria and ventricles of the heart. This condition involves malformations in the atrial and ventricular septa, as well as abnormalities in the atrioventricular valves.
✓ Monitor respiratory status closely, as infants with AV canal defects may experience respiratory distress related to heart failure. Signs of respiratory distress may include tachypnea, retractions, and nasal flaring.
✓ Practice infection prevention measures, as infants with congenital heart defects may be at an increased risk of infections. Promote hand hygiene, ensure a clean environment, and educate caregivers on infection control practices.
