An infant with tetralogy of Fallot is experiencing a tet spell involving cyanosis and dyspnea. In which position should the infant be placed?

A.

Prone

B.

Knee-chest

C.

Trendelenburg's

D.

Fowler's

Answer and Explanation

The Correct Answer is B

A. Prone: Offers no circulatory or respiratory benefit during a tet spell.
B. Knee-chest: This position increases systemic vascular resistance, reducing the right-to-left shunt and improving oxygenation. It’s the standard first response for a tet spell.
C. Trendelenburg's: Can worsen respiratory distress and venous return; not used in cyanotic spells.
D. Fowler's: May help breathing generally but is less effective than the knee-chest position for managing a tet spell.

Correct Answer is A

Explanation

A. have a tracheotomy set at the bedside. Acute epiglottitis is a medical emergency due to the risk of sudden airway obstruction. Manipulating the throat may trigger complete airway blockage. Emergency airway equipment must be available.
B. restrain the child's arms. Restraint can worsen anxiety and possibly exacerbate airway obstruction.
C. immobilize the child's head. This is not a priority and may interfere with breathing efforts.
D. have oxygen available. While oxygen is important, having emergency airway support (e.g., tracheotomy) is the priority in case of airway collapse.
