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

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. At which age should the nurse expect most infants to begin to say mama and dada with meaning?

Correct answer: C

Rationale: By around 10 months, infants often start to say "mama" and "dada" with meaning, associating these words with their parents.

3. What laboratory finding should the nurse expect in a child with an excess of water?

Correct answer: A

Rationale: Water excess typically leads to hemodilution, resulting in a decreased hematocrit. High serum osmolality and specific gravity would indicate dehydration, while elevated BUN could suggest renal impairment or dehydration, not fluid overload.

4. The nurse is taking a health history of an adolescent. Which best describes how the chief complaint should be determined?

Correct answer: B

Rationale: Asking the adolescent directly about the reason for their visit encourages open communication and helps the nurse understand the primary concern from the patient's perspective.

5. The nurse has just started assessing a young child who is febrile and appears ill. There is hyperextension of the child's head (opisthotonos) with pain on flexion. Which is the most appropriate action?

Correct answer: B

Rationale: Opisthotonos with pain on flexion is a sign of possible meningitis or other serious neurological conditions, requiring immediate medical evaluation.
