Which term refers to the relative lactase deficiency observed in preterm infants of less than 34 weeks of gestation?
- A. Congenital lactase deficiency
- B. Primary lactase deficiency
- C. Secondary lactase deficiency
- D. Developmental lactase deficiency
Correct Answer: D
Rationale: 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.

An infant has been diagnosed with an allergy to milk. In teaching the parent how to meet the infants nutritional needs, the nurse states that
- A. Most children will grow out of the allergy.
- B. All dairy products must be eliminated from the childs diet.
- C. It is important to have the entire family follow the special diet.
- D. Antihistamines can be used so the child can have milk products.

These foods include processed meats, salad dressings, soups, and milk chocolate. Having the entire family follow the special diet would provide support for the child, but the nutritional needs of other family members must be addressed. Antihistamines are not used for food allergies.

The nurse is teaching a parent with a 2-month-old infant who has been diagnosed with colic about ways to relieve colic. Which statement by the parent indicates the need for additional teaching?
- A. I should let my infant cry for at least 30 minutes before I respond.
- B. I will swaddle my infant tightly with a soft blanket.
- C. I should massage my infants abdomen whenever possible.
- D. I will place my infant in an upright seat after feeding.
Correct Answer: A
Rationale: Because the infant has been diagnosed with colic, the parent should respond to the infant immediately or any type of interventions to relieve colic may not be effective. Also, the infant may develop a mistrust of the world if his or her needs are not met. The parent should swaddle the baby tightly with a soft blanket, massage the babys abdomen, and place the infant in an upright seat after a feeding to help relieve colic.
The nurse is examining an infant, age 10 months, who was brought to the clinic for persistent diaper rash. The nurse finds perianal inflammation with satellite lesions. What is the most likely cause?
- A. Impetigo
- B. Urine and feces
- C. Candida albicans infection
- D. Infrequent diapering
Correct Answer: C
Rationale: C. albicans infection produces perianal inflammation and a maculopapular rash with satellite lesions that may cross the inguinal folds. Impetigo is a bacterial infection that spreads peripherally in sharply marginated, irregular outlines. Eruptions involving the skin in contact with the diaper but sparing the folds are likely to be caused by chemical irritation, especially urine and feces, and may be related to infrequent diapering.
A new parent asks the nurse, How can diaper rash be prevented? What should the nurse recommend?
- A. Wash the infant with soap before applying a thin layer of oil.
- B. Clean the infant with soap and water every time diaper is changed.
- C. Wipe stool from the skin using water and a mild cleanser.
- D. When changing the diaper, wipe the buttocks with oil and powder the creases.
Correct Answer: C
Rationale: Change the diaper as soon as it becomes soiled. Gently wipe stool from the skin with water and mild soap. The skin should be thoroughly dried after washing. Applying oil does not create an effective barrier. Over washing the skin should be avoided, especially with perfumed soaps or commercial wipes, which may be irritating. Baby powder should not be used because of the danger of aspiration.
