(B) The diaper should be folded below the cord to allow the cord stump to be exposed to the air for healing. (C) The umbilical cord should be swabbed with alcohol at each diaper change to remove urine and stool and to facilitate the desiccation process through drying. (D) Soap and water should not be used to clean the umbilical area because the area could retain moisture, thus making it susceptible to bacterial growth and infection.
2. Right Answer: C
Explanation: (A) This practice is the proper use of the bulb syringe to clear the infants airway in case of regurgitation.

(B) It is important that the infant take in 23 full days of milk or formula feedings to preclude a false-negative reading. (C) At 23 days of age, inadequate milk could have been ingested owing to a delay in the initial feeding. (D) The biochemical buildup of serum phenylalanine is detectable after 23 days of milk or formula ingestion.

Explanation: (A) This condition causes aseptic necrosis of the head of the femur in the acetabulum. Drinking large quantities of milk at this time cannot hasten recovery. (B)The aim of treatment is to keep the head of the femur in the acetabulum. Nonweight-bearing is essential. Activity causes microfractures of the epiphysis. (C) In addition to nonweight-bearing, clients are often placed on bedrest, which helps to reduce inflammation. Later, active motion is encouraged. (D) Weight is not generally an issue with this disease. Slipped femoral capital epiphysis, which is most frequently observed in obese pubescent children, usually requires a weight reduction diet.
