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. Which characteristic best describes the fine motor skills of an infant at age 5 months?

Correct answer: D

Rationale: By 5 months, infants develop the ability to grasp objects voluntarily, showing improved motor control. The neat pincer grasp and building towers are skills that develop later.

3. By which age should the nurse expect that an infant will be able to pull to a standing position?

Correct answer: C

Rationale: Pulling to a standing position typically occurs between 11 to 12 months, marking the progression towards walking.

4. The parent of a 3-month-old infant is concerned because the infant is not able to sit independently. How should the nurse respond to this parent's concern?

Correct answer: D

Rationale: The correct answer is D because sitting steadily typically occurs closer to 6-8 months of age, not 3 or 4 months. Choice A is incorrect because sitting ability and the age of first tooth eruption are not related. Choice B and C are incorrect as most infants do not sit steadily at 3 or 4 months, and it is more common for infants to achieve this milestone around 6-8 months.

5. What major complication is associated with a child with chronic renal failure?

Correct answer: C

Rationale: Water and sodium retention is a major complication in chronic renal failure, leading to hypertension and edema. Hypokalemia and metabolic alkalosis are less common, and while BUN levels rise, retention rather than excretion is problematic in chronic renal failure.
