Rationale: Vegetables, particularly pureed ones, are often recommended as a first solid food for infants because they are easy to digest and less likely to cause allergies. Fruits can be introduced later due to their natural sweetness, while eggs and meat are typically introduced after fruits and vegetables as they may pose a higher risk of allergies.

Correct Answer: B

Rationale: The correct answer is B. Irregular respirations with periodic pauses are normal in a 1-month-old infant. Choice A is incorrect because the normal respiratory rate for an infant at this age is higher than the range provided. Choice C is incorrect as irregular respirations are expected in infants. Choice D is not appropriate as irregular respirations with periodic pauses are a normal finding in young infants and do not necessarily indicate a concern that requires immediate notification of the healthcare provider.

Correct Answer: C

Rationale: Renal transplantation is the preferred method of treatment for children with end-stage renal disease, as it offers the best chance for a normal lifestyle compared to long-term dialysis. Transplantation can be performed at any age, and kidneys can come from adult donors as well.

Correct Answer: D

Rationale: The correct answer is D because babbling is an early indicator of hearing ability in infants. Lack of babbling by 2 months may suggest a potential hearing issue. Choices A, B, and C are incorrect because turning away from a sound, startling with sudden loud noises immediately after birth, and talking at 4 months are not primary indicators of hearing loss in infants.
