Correct Answer: B

Rationale: Introducing new foods gradually and offering a variety of options is a suitable nutritional goal for preschool-aged children as it helps in providing essential nutrients and expanding their palate. Choice A is incorrect as reducing messiness and spills is more related to behavior than nutrition. Choice C is incorrect as forcing a child to finish all the food on the plate may override their natural hunger and fullness cues. Choice D is incorrect as allowing a child to eat only preferred foods may lead to an imbalanced diet lacking in essential nutrients.

Correct Answer: C

Rationale: Masturbation in preschool children is a normal behavior as they explore their bodies. It is best viewed as a natural part of development. Parents are often advised to ignore it and provide distractions rather than making the child feel ashamed or embarrassed. Choice A is incorrect because it is a natural behavior and not considered abnormal in this context. Choice B is incorrect as it does not necessarily disrupt the family. Choice D is incorrect as the focus should be on the child's development and well-being, not on the parents' feelings of embarrassment.

Correct Answer: A

Rationale: The correct answer is A: 1 year. By the age of 1 year, a baby's birth weight typically triples. This period allows for significant growth and development in infants. Choices B, C, and D are incorrect because birth weight does not usually triple by 1 month, 2 years, or 6 months of age, respectively.

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.

Correct Answer: D

Rationale: Facial expression has consistently been validated as an indicator of pain in infants. Behavioral pain measures are most reliable for sharp procedural pain in infants. Increased heart rate and respirations are indicative of a generalized and complex response to stress, not specific for pain in infants. Thrashing of arms and legs is a reliable indicator in young children, not specifically in infants.
