A nurse is reinforcing teaching about food choices with a parent of a child who has celiac disease. Which of the following responses 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:
Headache is an expected finding in a school-age child with bacterial meningitis. Bacterial meningitis is an inflammation of the meninges, and the membranes surrounding the brain and spinal cord, often caused by bacteria. The inflammatory process can lead to increased intracranial pressure, which commonly presents as a headache. This headache is often severe and can be accompanied by other symptoms like fever, irritability, and sensitivity to light.
Choice B rationale:
A negative Kernig sign is a possible finding in a school-age child with bacterial meningitis. Kernig sign is a clinical test performed to assess for meningitis. A positive Kernig sign is characterized by resistance and pain in extending the knee when the hip is flexed at a 90-degree angle. However, a negative Kernig sign does not rule out meningitis, as it might not always be present.
Choice C rationale:
Vomiting is an expected finding in a school-age child with bacterial meningitis. The increase in intracranial pressure due to inflammation of the meninges can lead to nausea and vomiting. The vomiting is often projectile and may not be relieved by eating or drinking.
Choice D rationale:
Seizures are an expected finding in a school-age child with bacterial meningitis. The inflammation of the brain and meninges can irritate the brain tissue and trigger seizures. Seizures in the context of bacterial meningitis might be generalized or focal in nature.
Choice E rationale:
Tinnitus (ringing in the ears) is not a typical finding associated with bacterial meningitis. The main symptoms of bacterial meningitis are related to the central nervous system and meningeal irritation, such as headache, fever, neck stiffness, and neurological changes. Tinnitus is not a common manifestation of bacterial meningitis and is not part of the typical clinical picture.
