Correct Answer: B

Rationale: Mortality statistics describe the number of individuals who have died over a specific period, providing insight into public health concerns.

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.

Correct Answer: D

Rationale: The correct answer is D. Recall of food intake, especially amounts eaten, is often unreliable. While systematic tools like the 24-hour recall and dietary history questionnaires exist, recall can still be challenging in accurately assessing a child's dietary intake. Choices A, B, and C are incorrect because systematic assessment tools do exist, biochemical analysis is not the primary method for dietary assessment, and families' understanding of nutrition may vary but is not the main reason for the difficulty in assessing a child's dietary intake.

Correct Answer: C

Rationale: Unintentional injuries are the leading cause of death among children older than 1 year in the United States.

Correct Answer: B

Rationale: The correct answer is B: Rice cereal. Rice cereal is typically the first solid food introduced to infants because it is easy to digest and unlikely to cause an allergic reaction. Starting with rice cereal helps assess the baby's readiness for solid foods and reduces the risk of allergic responses. Choice A (Meat) is not recommended as the initial solid food due to its higher allergenic potential. Choices C (Fruits) and D (Vegetables) are also not usually recommended as the first solid food, as they may be more challenging for infants to digest compared to rice cereal.
