The nurse knows which congenital cardiac defect is characterized by a mixing of well-oxygenated blood with poorly oxygenated blood.
Hypoplastic heart syndrome
Atrioventricular canal defect
Tetralogy of Fallot
Coarctation of the aorta
The Correct Answer is B
A. Hypoplastic heart syndrome: Characterized by underdevelopment of the left side of the heart, not mixing of blood.
B. Atrioventricular canal defect: An atrioventricular canal defect allows oxygenated and deoxygenated blood to mix due to the presence of a common atrioventricular valve and defects in the atrial and ventricular septa. This defect results in a mixture of oxygenated and deoxygenated blood, which can cause varying levels of oxygenation in the blood delivered to the body.
C. Tetralogy of Fallot: Involves a ventricular septal defect leading to right-to-left shunting, but not a direct mixing of oxygenated and deoxygenated blood.
D. Coarctation of the aorta: Involves narrowing of the aorta, not mixing of oxygenated and deoxygenated blood.

Correct Answer is ["A","C","E"]
Explanation
A. Offer the newborn a pacifier. This can help soothe the newborn and provide comfort, as infants exposed to opioids in utero often exhibit increased need for sucking.
B. Observe the newborn in a well-lit nursery. This is not appropriate as bright lights can overstimulate and distress the newborn.
C. Maintain a low stimulation environment. This helps reduce stress and irritability in newborns undergoing withdrawal, who can be hypersensitive to stimuli.
D. Administer oral glucose for comfort. Glucose is not typically used for comfort in NAS management; comforting measures like swaddling and pacifiers are preferred.
E. Swaddle the newborn tightly. Tight swaddling can provide a sense of security and help manage symptoms of neonatal abstinence syndrome (NAS) by reducing irritability and promoting sleep.
F. Feed the infant half-strength formula. Infants with NAS usually require regular, full-strength formula to meet nutritional needs unless otherwise indicated by specific feeding issues.
