A nurse is assisting with the collection of a bone marrow specimen from a preschooler. Which of the following actions should the nurse take?

Choice A rationale:
The nurse should report the finding of a 6-month-old infant with a spiral fracture to a lower extremity to local authorities. Spiral fractures in infants, especially those who are not yet independently mobile, raise concerns about possible child abuse or non-accidental trauma. The unique pattern of spiral fractures is often associated with twisting forces, which are unlikely to occur accidentally in infants who cannot perform such movements. Reporting such cases is essential to ensure the safety and well-being of the child.
Choice B rationale:
A 9-month-old infant exposed to bedbugs and cellulitis is not an emergency that requires reporting to local authorities. While cellulitis can be serious, it is not an immediate threat to the child's safety, and the focus should be on providing appropriate medical care.
Choice C rationale:
A 4-year-old preschooler with rivalry among siblings does not indicate a need for reporting to local authorities. Sibling rivalry is a common occurrence in families and does not pose a threat to the child's safety. It is a social and developmental issue that can be addressed within the family.
Choice D rationale:
A 24-month-old toddler experiencing occasional incontinence does not require reporting to local authorities. Occasional incontinence can be a normal part of toddler development as they learn to control their bladder. It does not indicate abuse or immediate danger to the child.

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.
