Passage / Scenario
A boy with Tetralogy of Fallot.The nurse would teach the mother of a boy with Tetralogy of Fallot that if the child suddenly becomes cyanotic and dyspneic, the mother should:
Correct answer
A
Rationale
The correct answer is A: Place him in knee-chest position. This position helps increase venous return to the heart, improving oxygenation. Placing the child in knee-chest position helps reduce the workload on the heart, leading to improved circulation and oxygenation. This position also helps alleviate the cyanosis and dyspnea quickly.
Choice B is incorrect because lying prone may worsen the child's ability to breathe due to pressure on the chest and abdomen. Choice C is incorrect because lying supine with the head turned to one side does not facilitate improved oxygenation in this situation. Choice D is incorrect as placing the child in semi-fowler's position in an infant seat may not provide the immediate relief needed for cyanosis and dyspnea.
