A child with a disorder leading to cyanosis from deoxygenated blood entering the systemic arterial circulation
Question 1 of 5
Which of the following disorders leads to cyanosis from deoxygenated blood entering the systemic arterial circulation?
Correct Answer: D
Rationale: The correct answer is D: Tetralogy of Fallot. In TOF, there is a VSD, overriding aorta, pulmonary stenosis, and right ventricular hypertrophy. The pulmonary stenosis causes decreased blood flow to the lungs, leading to deoxygenated blood entering the systemic circulation, resulting in cyanosis.
A: Coarctation of aorta results in hypertension in upper limbs, not cyanosis.
B: Aortic stenosis causes obstruction of blood flow from the left ventricle to the aorta, not leading to cyanosis.
C: PDA results in a left-to-right shunt, causing increased pulmonary blood flow, not deoxygenated blood in systemic circulation.
E, F, G: No information given.
