by the mother in the last

3. Parents report their

healthcare professional prepare to educate the parent

on?

b. A gastric feeding tube

c. Corrective surgery

d. Lactose-free diet

4. Which term is used to identify

a condition in which the deC. Cleft lip

Rationale: A cleft lip is caused by the incomplete fusion of the nasomedial and intermaxillary process during the fourth week

of embryonic development.

d. Pyloric stenosis

Rationale: Increased gastrin secretion by

the mother in the last trimester of pregnancy increases the likelihood of pyloric

stenosis in the infant. The overproduction

of gastric secretions in the infant may be

caused by stress-related factors in the mother. Increased gastrin secretion does not lead

to meconium ileus, esophageal atresia, or

galactosemia.

c. Corrective surgery

Rationale: This infant is displaying symptoms of pyloric stenosis. The key treatment

for pyloric stenosis is corrective surgery,

usually a laparoscopic pyloromyotomy. A

feeding tube is not needed; a wheat-free

diet would be indicated for celiac disease or

nonceliac gluten sensitivity; lactose-free diet

would be beneficial in lactose sensitivity.

d. Intestinal malrotation
