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. A child with a diagnosis of cystic fibrosis is admitted to the hospital. What is the priority nursing intervention?

Correct answer: A

Rationale: The correct answer is administering pancreatic enzymes. In cystic fibrosis, the pancreas is often affected, leading to insufficient production of digestive enzymes. Administering pancreatic enzymes is crucial to ensure proper digestion and absorption of nutrients. While respiratory therapy, nutritional support, and physical activity are essential components of care for individuals with cystic fibrosis, addressing the digestive aspect by administering pancreatic enzymes takes priority to prevent malnutrition and promote overall health.

3. A 1-month-old girl with low-set ears and severe hypotonia has been diagnosed with trisomy 18. Which nursing diagnosis would the nurse identify as most likely?

Correct answer: C

Rationale: The most likely nursing diagnosis for a 1-month-old girl with trisomy 18, characterized by low-set ears and severe hypotonia, is 'Grieving related to the child's poor prognosis.' Trisomy 18 is associated with a poor prognosis, and families often experience grief as they come to terms with the challenges and uncertainties associated with the condition. 'Interrupted family process' may not be as relevant since the primary focus is on the child's condition. 'Deficient knowledge related to the genetic disorder' could be important but may not be the most likely initial concern, as emotional support for the family is crucial at this point. 'Ineffective coping related to the stress of providing care' is a broad diagnosis that does not specifically address the emotional response to the child's prognosis, which is the primary concern in this case.

4. A nurse is assessing a child with suspected pertussis. What clinical manifestation is the nurse likely to observe?

Correct answer: D

Rationale: The correct answer is D: Severe coughing spells. Pertussis, also known as whooping cough, typically presents with severe coughing spells that can be followed by a characteristic 'whoop' sound. These coughing fits can be intense and prolonged, often causing the child to gasp for air between coughs. Option A, dry hacking cough, is a common symptom of other respiratory conditions like bronchitis. Option B, inspiratory stridor, is more commonly associated with conditions like croup. Option C, nasal congestion, is not a typical symptom of pertussis.

5. A healthcare professional is teaching parents about why most children should be immunized against varicella (chickenpox) and why some receiving specific medications should not. Which medication should be included in the discussion?

Correct answer: B

Rationale: The correct answer is B: Steroids. Children receiving steroids should not receive the varicella vaccine as it can increase the risk of severe infection due to the immunosuppressive effects of steroids. Insulin (Choice A) is not a medication that contraindicates varicella vaccination. Antibiotics (Choice C) and anticonvulsants (Choice D) are also not medications that would impact the decision to immunize against varicella.
