Nursing Elites

1. The mother of an infant diagnosed with bronchiolitis asks the nurse what causes the disease. How should the nurse respond?

• A. Respiratory syncytial virus (RSV)
• B. Haemophilus influenzae
• C. Parainfluenza
• D. Rotavirus

Correct answer: A

Rationale: The correct answer is A: Respiratory syncytial virus (RSV). RSV is the most common cause of bronchiolitis, especially in infants. Bronchiolitis is characterized by inflammation of the small airways in the lungs. Choice B, Haemophilus influenzae, is a bacterium that can cause respiratory infections but is not the primary cause of bronchiolitis. Choice C, Parainfluenza, is a common viral infection that can cause croup and other respiratory illnesses but is not the main cause of bronchiolitis. Choice D, Rotavirus, is a virus that primarily affects the gastrointestinal system, causing diarrhea and vomiting, and is not associated with bronchiolitis.

2. In teaching the parent of a newly diagnosed 2-year-old child with pyelonephritis related to vesicoureteral reflux (VUR), the nurse should include which information?

• A. Limit fluids to reduce reflux.
• B. Give cranberry juice twice a day.
• C. Have siblings examined for VUR.
• D. Surgery is indicated to reverse scarring.

Correct answer: C

Rationale: Siblings should be examined for VUR as it can run in families, and early detection can prevent complications. Limiting fluids is not advisable, and cranberry juice is not effective in preventing VUR. Surgery is usually not indicated for scarring reversal.

3. Which laboratory test would be most important for the nurse to assess when caring for a toddler suspected of having cystic fibrosis?

• A. Liver enzymes
• B. Serum calcium
• C. Sweat chloride test
• D. Urine creatinine

Correct answer: C

Rationale: The sweat chloride test is the primary diagnostic test for cystic fibrosis. Cystic fibrosis is characterized by abnormal transport of chloride and sodium across epithelial cell membranes, leading to increased chloride in sweat. This test is crucial for diagnosing cystic fibrosis in suspected cases. Liver enzymes (Choice A), serum calcium (Choice B), and urine creatinine (Choice D) are not specific tests for cystic fibrosis and would not provide the necessary information for diagnosis in this case.

4. What clinical manifestation(s) is associated with calcium depletion (hypocalcemia)?

• A. Nausea, vomiting
• B. Weakness, fatigue
• C. Muscle hypotonicity
• D. Neuromuscular irritability

Correct answer: D

Rationale: Hypocalcemia can lead to neuromuscular irritability, causing symptoms such as muscle cramps, tetany, or seizures. Other symptoms like nausea, vomiting, and weakness are less specific and can be related to various conditions.

5. When checking the intravenous (IV) site on a child, the nurse should take which action?

• A. Look at the site.
• B. Ask the child if the site hurts.
• C. Look at the site while palpating the area.
• D. Take all the tape off, assess the site, and redress.

Correct answer: C

Rationale: Looking at and palpating the IV site helps assess for signs of infiltration or infection, such as swelling, redness, or pain. Simply looking or asking the child may miss subtle signs, and removing all the tape unnecessarily disrupts the site.
