A pediatric nurse is seeing a B-year-old following a post-cardiac catheterization procedure. Which of the following interventions ordered by the physician should be questioned by the nurse? [Select All that Apply)

Hypercyanotic spells, also known as "Tet spells," can occur in infants with congenital heart defects, particularly tetralogy of Fallot. During these spells, there is a sudden decrease in oxygen saturation, leading to cyanosis (blueness) of the infant's skin and lips, as well as respiratory distress and possible loss of consciousness.
The knee-chest position is a specific technique used to manage hypercyanotic spells. Placing the child in this position helps improve oxygenation by increasing systemic vascular resistance and reducing the degree of right-to-left shunting of blood in the heart. It also increases venous return to the heart, which can help improve cardiac output.

Now, let's discuss why the other options are incorrect:
A. Prepare family for imminent death: This is not the priority action. While hypercyanotic spells can be life-threatening, the immediate focus should be on managing the spell to improve oxygenation and prevent further deterioration. Preparing the family for death should only be considered if resuscitation measures fail, which is not the first-line intervention.
C. Assess for neurologic defects: Assessing for neurologic defects is important but not the immediate priority during a hypercyanotic spell. The primary concern at this moment is addressing cyanosis and respiratory distress to ensure the infant receives adequate oxygen.
D. Begin cardiopulmonary resuscitation: Initiating CPR is not the initial priority during a hypercyanotic spell. CPR would be indicated if the infant's condition deteriorates to the point of cardiac arrest, but it should not be the first step. Placing the child in the knee-chest position is a non-invasive intervention that should be attempted before considering CPR.

Infants with congenital heart defects, including VSD, may have increased caloric needs due to the added work of their hearts. Congestive heart failure can lead to poor weight gain and failure to thrive. Therefore, increasing the caloric density of the formula is a common approach to providing the necessary nutrition for growth and development. This can be achieved by using specialized high-calorie infant formulas or fortifying breast milk.

The other options are not the primary supportive measures for an infant with congestive heart failure in this context:

B. Oxygen therapy to ensure oxygen saturation is > 98%: While oxygen therapy may be necessary for infants with congenital heart defects, it is not the primary supportive measure to address failure to thrive. Oxygen therapy primarily aims to ensure adequate oxygenation but does not directly address caloric intake.

C. Sedatives to keep the infant from crying: The use of sedatives is not a typical approach to managing congestive heart failure in infants. Addressing the underlying cause, optimizing nutrition, and providing supportive care are more appropriate strategies.

D. Emergent surgical correction of the defect: Surgical correction of a VSD is typically considered for specific indications, such as significant hemodynamic compromise, but it is not the first-line intervention for all cases of VSD, especially if the primary concern is failure to thrive. Treatment decisions for VSD are made based on the specific clinical presentation and severity of the defect.
