Nursing Elites

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?

• A. Chest X-ray
• B. Sweat chloride test
• C. Pulmonary function test
• D. Sputum culture

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 is the primary treatment for minimal change nephrotic syndrome?

• A. corticosteroids
• B. antihypertensive agents
• C. long-term diuretics
• D. increased fluids to promote diuresis

Correct answer: A

Rationale: Corticosteroids are the mainstay of treatment for minimal change nephrotic syndrome due to their immunosuppressive effects, which help reduce proteinuria and control the disease progression. Antihypertensive agents are not the primary treatment for this condition and are typically used to manage hypertension that may result from nephrotic syndrome. Long-term diuretics are not indicated in the treatment of minimal change nephrotic syndrome as they do not address the underlying cause. Increasing fluids to promote diuresis is not a recommended treatment for minimal change nephrotic syndrome, as it can exacerbate edema and fluid overload in these patients.

3. A nurse is providing care to a child with a diagnosis of bronchiolitis. What is the priority nursing intervention?

• A. Administering bronchodilators
• B. Providing respiratory therapy
• C. Monitoring oxygen saturation
• D. Encouraging fluid intake

Correct answer: B

Rationale: The correct answer is providing respiratory therapy. In bronchiolitis, the priority is to maintain airway patency through interventions such as suctioning, positioning, and oxygen therapy. While bronchodilators may be used in some cases, they are not the initial priority. Monitoring oxygen saturation is important but comes after ensuring airway patency. Encouraging fluid intake is essential for hydration but is not the priority over maintaining a patent airway.

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

• A. Webbed neck
• B. Microcephaly
• C. Gynecomastia
• D. Cognitive delay

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.

5. A child with diabetes insipidus is being treated with vasopressin. The nurse would assess the child closely for signs and symptoms of which condition?

• A. Syndrome of inappropriate antidiuretic hormone (SIADH)
• B. Thyroid storm
• C. Cushing syndrome
• D. Vitamin D toxicity

Correct answer: A

Rationale: The correct answer is A: Syndrome of inappropriate antidiuretic hormone (SIADH). Vasopressin is a medication used to treat diabetes insipidus by increasing water reabsorption in the kidneys. However, an excessive dose of vasopressin can lead to water retention, causing SIADH, which is characterized by dilutional hyponatremia. Choices B, C, and D are incorrect. Thyroid storm is a severe form of hyperthyroidism characterized by increased metabolism and can lead to life-threatening complications. Cushing syndrome results from excess cortisol production and is characterized by weight gain, hypertension, and other features. Vitamin D toxicity occurs due to an overdose of vitamin D, leading to hypercalcemia and symptoms such as nausea, vomiting, and weakness.
