1. What factor predisposes an infant to fluid imbalances?

Correct answer: C

Rationale: Infants have immature kidneys that are less efficient at concentrating urine, making them more susceptible to fluid imbalances. Their higher surface area to volume ratio also contributes to greater insensible fluid losses.

2. Which type of family should the nurse recognize when the paternal grandmother, the parents, and two minor children live together?

Correct answer: C

Rationale: An extended family includes relatives such as grandparents, aunts, uncles, and other extended family members living together, beyond just the nuclear family unit.

3. Parents of a newborn with ambiguous genitalia want to know how long they will have to wait to know whether they have a boy or a girl. The nurse answers the parents based on what knowledge?

Correct answer: D

Rationale: Gender assignment in cases of ambiguous genitalia is a complex process that requires a multidisciplinary approach, including genetic, endocrinological, and psychological evaluations. The decision should be made collaboratively with the parents.

4. What is the most common cause of bronchiolitis in infants?

Correct answer: C

Rationale: The correct answer is C, Respiratory syncytial virus (RSV). RSV is the leading cause of bronchiolitis, a common respiratory condition in infants that results in inflammation of the small airways in the lung. It is highly contagious and can cause severe respiratory distress in young children, particularly those under 2 years old. Choice A, Adenovirus, is not the most common cause of bronchiolitis in infants. Choice B, Influenza virus, may cause respiratory infections but is not the primary cause of bronchiolitis. Choice D, Parainfluenza virus, can cause croup and other upper respiratory infections but is not the main cause of bronchiolitis in infants.

5. The nurse is teaching parents guidelines for feeding their 8-month-old infant with failure to thrive (FTT). Which statement by the parents indicates a need for further teaching?

Correct answer: C

Rationale: Providing 8 oz of juice daily is excessive for an 8-month-old infant and can displace other nutrient-rich foods or formulas that are necessary for growth, especially in an infant with FTT.
