Which compensatory position will the nurse observe in a child with tetralogy of Fallot (TOF) who is experiencing a hypercyanotic spell?
A) In a high-Fowler position
B) Supine with the legs elevated
C) With knees pulled up to chest
D) On the left side
C) With knees pulled up to chest
Explanation: A) Infants with TOF have hypercyanotic spells, also known as Tet spells, when crying or with exertion. During a Tet spell, the infants pull their knees up to their chest, the effect being a reduction of systemic venous return and an increase in systemic vascular pressure. This compensatory movement helps to decrease the cyanosis for the time being.
