A parent brings a 2-week-old infant to a clinic for a phenylketonuria rescreening blood test. The test indicates a serum phenylalanine level of 1 mg/dL (60.5 mcmol/L). The nurse reviews this result and makes which interpretation?

A. Need for increased caloric intake:
Incorrect: While toddlers may have specific nutritional needs, it is important to focus on a balanced diet rather than emphasizing increased caloric intake. The emphasis should be on providing nutritious and age-appropriate foods.
B. How to encourage cooperative play:
Correct Answer: Encouraging cooperative play is important for a toddler's social development. It involves teaching sharing, taking turns, and interacting with other children.
C. Management of tantrums:
Incorrect: While guidance on managing tantrums can be part of parenting education, it may not be the primary focus in health promotion teaching. The emphasis is typically on positive guidance, effective communication, and setting age-appropriate limits.
D. Dental care:
Correct Answer: Dental care is crucial for toddlers to promote oral health. The nurse should provide information on proper oral hygiene practices, including tooth brushing, and discuss the importance of regular dental check-ups.
E. How to establish trust:
Correct Answer: Establishing trust is a vital aspect of toddler development. The nurse can provide guidance on building a secure and trusting relationship between the child and parents.

A. Sausage-shaped mass palpated in the upper right abdominal quadrant.
Explanation: A sausage-shaped mass in the upper right abdominal quadrant is more indicative of Hirschsprung's disease, not imperforate anus. In Hirschsprung's disease, there is a lack of ganglion cells in the rectum, leading to obstruction and a palpable mass.
B. The passage of currant jelly-like stools.
Explanation: The passage of currant jelly-like stools is characteristic of intussusception, a condition where one portion of the intestine telescopes into another. It is not associated with imperforate anus.
C. Bile-stained fecal emesis.
Explanation: Bile-stained fecal emesis suggests a possible intestinal obstruction or other gastrointestinal issue, but it is not a specific manifestation of imperforate anus. Imperforate anus is primarily characterized by the absence of a normal anal opening.
D. Failure to pass meconium stool in the first 24 hours after birth.
Explanation:
Imperforate anus refers to a congenital condition in which the opening to the anus is absent or improperly formed. One of the clinical manifestations is the failure to pass meconium stool within the first 24 hours after birth. Meconium is the thick, sticky, greenish-black substance that constitutes a newborn's first stools. The absence of meconium passage suggests a potential obstruction.
