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 sweat chloride test is the gold standard diagnostic test for cystic fibrosis as it measures the concentration of chloride in sweat. In cystic fibrosis, there is an abnormal transport of chloride across epithelial membranes, leading to elevated sweat chloride levels. A chest X-ray may show characteristic changes in the lungs associated with cystic fibrosis, but it is not a definitive diagnostic test. Pulmonary function tests assess lung function but do not specifically diagnose cystic fibrosis. Sputum culture may identify respiratory infections but does not confirm the diagnosis of cystic fibrosis.

Correct Answer: D

Rationale: A common clinical manifestation of bacterial meningitis is a positive Kernig sign, indicating irritation of the meninges. Rash (Choice A) is not typically associated with bacterial meningitis. Photophobia (Choice B) can be present but is more commonly seen in viral meningitis. Jaundice (Choice C) is not a typical clinical manifestation of meningitis and is more indicative of liver dysfunction.

Correct Answer: D

Rationale: At 10 months of age, pulling to a stand is a developmental milestone that most infants can achieve. Crawling typically occurs around 6-9 months, sitting without support around 6-8 months, and standing with assistance around 7-11 months. Therefore, choices A, B, and C are not the expected developmental milestones for a 10-month-old infant.

Correct Answer: D

Rationale: Teaching seizure first aid to family members is crucial for ensuring the child's safety during a seizure. Keeping a diary of seizure activity (choice A) is important for tracking patterns and triggers but does not directly relate to immediate safety during a seizure. Administering antiepileptic medication only when a seizure occurs (choice B) is incorrect as medications should be given as prescribed to maintain therapeutic levels. Restricting the child's activities to prevent seizures (choice C) is not an appropriate approach as it may limit the child's quality of life without guaranteeing seizure prevention.

Correct Answer: A

Rationale: The priority nursing intervention when caring for a child with sickle cell anemia is administering pain medication. Pain management is crucial in sickle cell anemia due to vaso-occlusive crises that can cause severe pain. While ensuring adequate hydration, providing nutritional support, and monitoring vital signs are important aspects of care for a child with sickle cell anemia, addressing the pain with appropriate medication takes precedence to alleviate the child's suffering and improve their quality of life.
