A 10-month-old infant is diagnosed with gastroesophageal reflux. An esophageal (pH) probe monitor is ordered. What explanation for the purpose of the esophageal probe should the nurse provide to the parents?

Correct Answer: B

Rationale: The correct answer is B. The esophageal pH probe is used to identify the frequency and severity of reflux episodes by measuring the pH in the esophagus. Choice A is incorrect because the probe does not assist in the passage of formula through the esophagus. Choice C is incorrect as determining the time it takes for the stomach to empty its contents would require a different procedure. Choice D is incorrect as the esophageal pH probe monitors the pH in the esophagus, not the stomach.

Correct Answer: A

Rationale: The first sign of puberty in boys is typically the enlargement of the testes. This is due to the increase in production of testosterone, which leads to physical changes such as growth of the testes. Choice B, decreased levels of testosterone, is incorrect as puberty is marked by an increase in testosterone levels. Choice C, voice deepening, and choice D, pubic hair growth, usually occur later in the puberty process compared to testicular enlargement, making them incorrect answers.

Correct Answer: A

Rationale: The correct answer is A. Putting an infant to bed with a bottle of milk or sweetened juice increases the risk of bottle mouth caries rather than decreasing it. This statement requires further teaching as it provides incorrect information. Choice B is correct as eliminating the bedtime bottle or substituting water is recommended to prevent bottle mouth caries. Choice C is also correct as sugar pooling within the oral cavity can indeed cause severe decay. Choice D is correct as bottle mouth caries is often observed in children between 18 months and 3 years.

Correct Answer: D

Rationale: The correct answer is D, 'Parallel.' Parallel play is a common play pattern observed in toddlers where they play alongside each other without direct interaction. This type of play allows toddlers to observe and mimic each other's actions, aiding in their social development. Choices A, B, and C are incorrect. Associative play involves some interaction between children, team play involves organized group activities, and solitary play is when a child plays alone, all of which are not typically exhibited by toddlers during play.
