Rationale: Urinary stasis is the most important factor in the development of UTIs because it provides an environment for bacterial growth. While poor hygiene and congenital anomalies are contributing factors, preventing urinary stasis is key in UTI prevention.

Correct Answer: B

Rationale: If the mother is HBsAg negative, it is recommended that the child receives the first dose of the hepatitis B vaccine at birth before discharge from the hospital. This is to provide early protection against the hepatitis B virus. The second dose of the vaccine is typically given at the first well-child visit, and the third dose is usually administered at a later date. The Advisory Committee on Immunization Practices of the Centers for Disease Control and Prevention and the Committee on Infectious Diseases of the American Academy of Pediatrics govern the recommendations for immunization, including the hepatitis B virus vaccine. Choice A is incorrect as the first dose should ideally be given at birth. Choice C is incorrect as waiting until 6 months of age may leave the child vulnerable to infection during the early months of life. Choice D is incorrect as the hepatitis B vaccine is recommended for all newborns, especially if the mother is HBsAg negative, to prevent transmission of the virus.

Correct Answer: D

Rationale: The correct answer is D, regression. Regression occurs when a child reverts to an earlier behavior, such as having accidents after being successfully toilet trained. This regression often happens due to stress or changes in routine. Choices A, B, and C are incorrect because positive reinforcement involves encouraging desired behavior, desensitization is a process of reducing sensitivity to a stimulus, and phobia is an intense fear or aversion to a specific object or situation, none of which directly apply to the described situation of the child having accidents after being toilet trained.

Correct Answer: A

Rationale: The correct action when intermittently gavage feeding a preterm infant is to allow the formula to flow by gravity. This method helps prevent overfeeding and aspiration, which can occur if the formula is delivered too quickly under pressure. Choice B is incorrect as sucking on the tube can cause complications. Choice C is incorrect as the tube is typically inserted through the mouth. Choice D is incorrect as steady pressure can lead to rapid delivery of the formula, increasing the risk of complications.
