A pediatric client is admitted to the unit with failure to thrive. The mother states that the child has been "spitting up" and excessively crying immediately after every bottle. What diagnostic test will the nurse anticipate to confirm a diagnosis?
Upper gastrointestinal series to determine structural abnormalities from gastroesophageal reflux
Biopsy of small intestine mucosa to rule out celiac disease
Ultrasound to assess for presence of pyloric stenosis
Lower gastrointestinal series to assess for an intestinal blockage
The Correct Answer is A
A. An upper gastrointestinal series is commonly used to diagnose gastroesophageal reflux (GER), which can cause symptoms like spitting up and crying after feedings, leading to failure to thrive. This test helps visualize the esophagus, stomach, and duodenum for abnormalities.
B. A biopsy of the small intestine is typically done to diagnose celiac disease, which is less likely in this clinical scenario.
C. An ultrasound is used to diagnose pyloric stenosis, which presents with projectile vomiting and is less consistent with the described symptoms.
D. A lower gastrointestinal series is used to detect intestinal blockages, which are not suggested by the symptoms of spitting up and crying immediately after feeding.

Correct Answer is A
Explanation
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 C
Explanation
A. Restricting fiber is not necessary; instead, administering vitamin C with iron can enhance absorption.
B. Iron supplements can cause dark stools, but not blood in the stools. Blood in the stools requires further investigation.
C. Routine monitoring of blood counts is crucial to assess the effectiveness of the iron supplementation and to adjust the dosage as needed.
D. Iron supplements are better absorbed on an empty stomach; taking them with meals can reduce their absorption.
