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.

Correct Answer: C

Rationale: Severe dehydration is the most common cause of acute renal failure in children, as it leads to prerenal azotemia, which can progress to renal failure if not corrected. Other causes like pyelonephritis and tubular destruction are less common and usually secondary to other conditions.

Correct Answer: A

Rationale: The correct answer is A. RSV is typically diagnosed by swabbing the nose and testing the secretions. This method helps confirm the presence of the respiratory syncytial virus. Choice B is incorrect because while symptoms are important in diagnosis, specific tests like swabbing for RSV do exist. Choice C is incorrect as sending a viral culture to an outside lab is not the primary method for diagnosing RSV. Choice D is a duplicate of choice B and is incorrect for the same reasons.
