A nurse is caring for a newborn who was recently delivered. Which of the following clinical signs would cause the nurse to suspect tricuspid atresia?
Profound cyanosis
Periorbital edema
Absent femoral pulses
Decreased blood pressure to lower extremities
The Correct Answer is A
A. Profound cyanosis is a key sign of tricuspid atresia, a congenital heart defect where the tricuspid valve is absent, leading to poor oxygenation of the blood.
B. Periorbital edema is not typically associated with tricuspid atresia; it might be seen in other conditions like nephrotic syndrome.
C. Absent femoral pulses suggest coarctation of the aorta rather than tricuspid atresia.
D. Decreased blood pressure in the lower extremities is also more indicative of coarctation of the aorta, not tricuspid atresia.

Correct Answer is A
Explanation
A. Acetaminophen can be used to manage mild discomfort after cardiac catheterization. It is a safe option for pain relief and is commonly recommended for children following the procedure.
B. Bed rest is typically recommended for a shorter duration, often 24 hours, not a full week. Extended bed rest is not usually required unless complications occur.
C. The diet should be advanced as tolerated, but there is no specific requirement to wait 24 hours; this will depend on the child’s recovery and tolerance.
D. Bathing recommendations often include avoiding submerging the site in water, so a tub bath may not be advised for the first few days to prevent infection. Sponge baths might be recommended instead.
Correct Answer is D
Explanation
A. Barrier creams should not be washed off with each diaper change; they should be left intact to protect the skin.
B. Cloth diapers can sometimes exacerbate diaper dermatitis due to moisture retention; disposable diapers may be better at wicking moisture away from the skin.
C. Talcum powder is not recommended due to the risk of inhalation, which can cause respiratory issues in infants.
D. Exposing the excoriated area to air frequently allows the skin to dry out, reducing moisture and irritation, which is beneficial in managing diaper dermatitis.
