1. What factor predisposes an infant to fluid imbalances?

• A. Decreased surface area
• B. Lower metabolic rate
• C. Immature kidney functioning
• D. Decreased daily exchange of extracellular fluid

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. A two-month-old infant who has gastroesophageal reflux is thriving without other complications. Which instruction should the nurse include in the teaching plan?

• A. Place the infant in the Trendelenburg position after feeding
• B. Thicken formula with rice cereal
• C. Give continuous nasogastric feedings
• D. Give larger, less frequent feeds

Correct answer: B

Rationale: The correct instruction for a two-month-old infant with gastroesophageal reflux who is thriving without complications is to thicken the formula with rice cereal. This can help reduce reflux by increasing the weight of the formula, making it less likely to be regurgitated. Placing the infant in the Trendelenburg position after feeding (Choice A) is not recommended as it can increase the risk of aspiration. Continuous nasogastric feedings (Choice C) are not typically indicated for uncomplicated reflux in infants. Giving larger, less frequent feeds (Choice D) can worsen reflux symptoms by overloading the stomach.

3. Which finding suggests fluid volume deficit in an infant presenting with vomiting and diarrhea for 2 days?

• A. Increased blood pressure
• B. A sunken fontanel
• C. Decreased pulse rate
• D. Low urine specific gravity

Correct answer: B

Rationale: A sunken fontanel is a classic sign of dehydration in infants, indicating a fluid volume deficit. In dehydration, the fontanel sinks due to decreased fluid volume in the body. Increased blood pressure (Choice A) is not typically associated with dehydration in infants. Decreased pulse rate (Choice C) is not a common finding in fluid volume deficit, as the body tries to increase the heart rate to compensate for decreased volume. Low urine specific gravity (Choice D) may be seen in dehydration, but it is not as specific or as easily observable as a sunken fontanel.

4. Which of the following is a key feature of autism spectrum disorder?

• A. Delayed speech development
• B. Hyperactivity
• C. Lack of interest in toys
• D. Aggressive behavior

Correct answer: A

Rationale: Delayed speech development is a significant feature of autism spectrum disorder. Many children with autism exhibit delays in speech and language development, which can be one of the early signs of the condition. Hyperactivity, lack of interest in toys, and aggressive behavior are not key defining features of autism spectrum disorder. While some individuals with autism may exhibit these behaviors, they are not universally characteristic of the disorder.

5. At which age can most infants sit steadily unsupported?

• A. 4 months
• B. 6 months
• C. 8 months
• D. 12 months

Correct answer: C

Rationale: Most infants can sit steadily without support by 8 months, indicating advanced gross motor skill development.
