A nurse is reinforcing teaching with the parent of a 6-month-old infant about introducing solid foods into the infant's diet. Which of the following statements by the parent indicates an understanding of the teaching?

Choice A rationale:
Lethargy, or extreme fatigue and sluggishness, is a characteristic symptom of hypothyroidism. Hypothyroidism occurs due to an underactive thyroid gland, which leads to a decrease in metabolic activity and energy levels. Children with hypothyroidism often exhibit lethargy, weakness, and a lack of interest in activities. This is due to the reduced metabolic rate and overall slowing down of bodily functions.
Choice B rationale:
Diarrhea is not a common finding associated with hypothyroidism. In fact, hypothyroidism tends to slow down gastrointestinal motility, leading to constipation rather than diarrhea. Therefore, diarrhea is not expected as a symptom in a child with hypothyroidism.
Choice C rationale:
Tachycardia, an elevated heart rate, is not typically associated with hypothyroidism. Instead, hypothyroidism often leads to bradycardia (a slower-than-normal heart rate) due to the overall slowing of the body's metabolic processes.
Choice D rationale:
Hirsutism, which refers to excessive hair growth in areas where hair growth is typically seen in males, is not a common finding in hypothyroidism. Hirsutism is more commonly associated with hormonal imbalances such as polycystic ovary syndrome (PCOS) rather than hypothyroidism.

Choice A rationale:
Avoiding discussions about the child's diagnosis with the sibling might create confusion and anxiety for the sibling. Open communication is essential for helping siblings understand their brother or sister's condition and cope with the changes in the family dynamic.
Choice B rationale:
Encouraging phone calls between the siblings is a positive step in promoting sibling adaptation when one of them has a chronic illness like cystic fibrosis. Maintaining connections through communication helps siblings feel involved, valued, and informed about each other's lives and challenges.
Choice C rationale:
Designating one parent to stay at home with the sibling might lead to feelings of isolation and neglect for the child with cystic fibrosis. Siblings also need support and attention during this time, and isolating one parent could hinder healthy sibling relationships.
Choice D rationale:
Avoiding having the sibling visit the child in the facility may prevent the sibling from understanding the condition and create a sense of fear or confusion. Controlled, supervised visits can actually be beneficial, as they allow the siblings to interact and support each other in a safe environment.
