A 3-year-old child with a history of frequent respiratory infections is being evaluated for cystic fibrosis. What diagnostic test should the nurse anticipate will be ordered?

Correct Answer: B

Rationale: The correct answer is the sweat chloride test. This test is crucial in diagnosing cystic fibrosis as it measures the amount of chloride in sweat, which is typically elevated in individuals with cystic fibrosis. A chest X-ray (Choice A) may show characteristic findings like hyperinflation or bronchiectasis, but it is not a definitive diagnostic test for cystic fibrosis. Pulmonary function tests (Choice C) may help assess lung function but are not specific for cystic fibrosis. Sputum culture (Choice D) may be used to identify specific pathogens causing respiratory infections but is not a primary diagnostic test for cystic fibrosis.

Correct Answer: D

Rationale: A common clinical manifestation of bacterial meningitis is a positive Kernig sign, which indicates meningeal irritation. Kernig sign is elicited when the leg is bent at the hip and knee at 90-degree angles, and pain and resistance are felt with extension at the knee due to inflamed meninges. Options A, B, and C are not typically associated with bacterial meningitis. A rash is more commonly seen in viral illnesses, photophobia can be present but is not specific to bacterial meningitis, and jaundice is not a typical clinical manifestation of this condition.

Correct Answer: D

Rationale: The correct answer is D: Pulling to a stand. By 10 months of age, most infants should be able to pull themselves up to a standing position while holding onto furniture or other support. This milestone indicates good strength and coordination in the lower body. Choice A, Crawling, is typically achieved around 6-9 months of age. Choice B, Sitting without support, usually occurs around 6-8 months. Choice C, Standing with assistance, can typically be seen around 9-12 months, but pulling to a stand is a more advanced milestone expected by 10 months.

Correct Answer: D

Rationale: Teaching seizure first aid to family members is essential as it empowers them to respond effectively during a seizure. Keeping a diary of seizure activity is important for tracking patterns and triggers but is not directly related to immediate safety. Administering antiepileptic medication only when a seizure occurs is not recommended as medications should be administered as prescribed by healthcare providers. Restricting the child's activities to prevent seizures is not appropriate as children with epilepsy should be encouraged to lead active lives while taking necessary precautions.

Correct Answer: A

Rationale: In sickle cell anemia, pain management is a priority due to vaso-occlusive crises that cause severe pain. Administering pain medication helps alleviate discomfort and improve the child's quality of life. Ensuring adequate hydration, although important, is secondary to addressing the immediate pain issue. Providing nutritional support is beneficial for overall health but does not address the acute pain experienced. Monitoring vital signs is essential but not the immediate priority when managing pain in sickle cell anemia.
