During a Tet spell while obtaining a blood specimen, which action should the nurse take first?

• A. Obtain a prescription for sedation for the child
• B. Assess for an irregular heart rate and rhythm
• C. Explain to the child that it will only hurt for a short time
• D. Place the child in a knee-to-chest position

Answer: (D)

During a Tet spell, the priority is to relieve the cyanosis quickly by increasing systemic vascular resistance and reducing the right-to-left shunt through the ventricular septal defect. Placing the child in a knee-to-chest position achieves this immediately, enhancing pulmonary blood flow and oxygenation. This quick, noninvasive maneuver is faster than waiting for sedation, and it directly addresses the hemodynamic change occurring during the spell. After positioning, provide oxygen if available, keep the child calm, and monitor vital signs to ensure stabilization.
