1. 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.

2. What finding would lead the nurse to suspect that a child has Turner syndrome?

Correct answer: A

Rationale: A webbed neck is a key feature seen in Turner syndrome, a genetic condition that occurs in females due to a complete or partial absence of one of the X chromosomes. This physical trait is caused by excess skin on the neck, giving it a webbed appearance. Microcephaly (Choice B) is a condition characterized by a smaller than average head size and is not typically associated with Turner syndrome. Gynecomastia (Choice C) refers to breast enlargement in males and is not a common finding in Turner syndrome, which affects females. Cognitive delay (Choice D) is not a specific characteristic of Turner syndrome, as the syndrome primarily affects physical development and may not necessarily impact cognitive abilities.

3. A child with a diagnosis of diabetes insipidus is admitted to the hospital. What is the priority nursing intervention?

Correct answer: B

Rationale: The correct priority nursing intervention for a child diagnosed with diabetes insipidus is to monitor fluid balance. Diabetes insipidus is a condition characterized by excessive urination and thirst, which can lead to dehydration. Monitoring fluid balance is essential to prevent dehydration and ensure the child's hydration status remains stable. Administering insulin (Choice A) is not indicated in diabetes insipidus because it is a disorder of the posterior pituitary gland, not the pancreas. Administering diuretics (Choice C) would exacerbate fluid loss in a child already at risk for dehydration. Monitoring vital signs (Choice D) is important but not the priority when compared to maintaining fluid balance in a child with diabetes insipidus.

4. Which of the following findings would indicate altered mental status in a small child?

Correct answer: C

Rationale: In a small child, displaying a lack of attention to the EMT-B's presence would indicate altered mental status. This behavior suggests a diminished level of consciousness or awareness, which is concerning. Recognizing the parents (Choice A) is a normal and expected behavior for a child. Showing fright at the EMT-B's presence (Choice B) may indicate fear or anxiety but not necessarily altered mental status. Maintaining consistent eye contact with the EMT-B (Choice D) may indicate engagement or curiosity rather than altered mental status.

5. A healthcare provider is assessing a child with suspected pneumonia. What clinical manifestation is the provider likely to observe?

Correct answer: A

Rationale: A cough is a common clinical manifestation of pneumonia. Pneumonia often presents with symptoms such as cough, fever, chest pain, and difficulty breathing. The inflammation and infection in the lungs lead to the characteristic cough observed in patients with pneumonia. Diarrhea, rash, and vomiting are not typically associated with pneumonia and are less likely to be observed in a child with this condition.
