Answer to Question 1

ANS: D
Developmental lactase deficiency refers to the relative lactase deficiency observed in preterm infants of less than 34 weeks of gestation. Congenital lactase deficiency occurs soon after birth after the newborn has consumed lactose-containing milk. Primary lactase deficiency, sometimes referred to as late-onset lactase deficiency, is the most common type of lactose intolerance and is manifested usually after 4 or 5 years of age. Secondary lactase deficiency may occur secondary to damage of the intestinal lumen, which decreases or destroys the enzyme lactase.

Answer to Question 2

ANS: B
The child and family should be exposed to the sights and sounds of the intensive care unit (ICU). All positive, nonfrightening aspects of the environment are emphasized. The family and child should make the decision about a tour of the unit if it is an option. The child should be shown unfamiliar equipment and its use demonstrated on a doll. Carefully prepare the child for the postoperative experience, including intravenous lines, incision, endotracheal tube, expected discomfort, and management strategies.
