Correct Answer: C

Rationale: Hypertonic solutions can damage tissues if they leak from the vein due to infiltration. It is crucial to monitor for this complication to prevent severe tissue damage. Infiltration is not solely related to the activity level of VLBW infants; it can occur due to various reasons such as vein condition, catheter placement, and fluid type. Continuous infusion pumps may not always detect infiltration, as they typically alarm for pressure changes but not all infiltration instances. Checking the infusion site regularly, preferably hourly, is essential to prevent complications like tissue damage from extravasations, fluid overload, and dehydration.

Correct Answer: C

Rationale: The correct answer is C: 'Abstract thinking.' According to Piaget's theory of cognitive development, adolescents, typically around the age of 12 and older, enter the formal operational stage where they can think abstractly and reason about hypothetical situations. When discussing complex topics like STIs with a 17-year-old student, it is essential to base the teaching plan on abstract thinking. Choice A, 'Sensorimotor reactions,' is incorrect as it pertains to the earliest stage in Piaget's theory (birth to 2 years old) focusing on sensory experiences and physical interactions. Choice B, 'Limited cause and effect understanding,' does not align with the cognitive abilities of a 17-year-old who is capable of more advanced thinking. Choice D, 'Concrete thinking,' is also incorrect as it refers to the stage before formal operations, where individuals think more concretely and struggle with abstract concepts.

Correct Answer: A

Rationale: The correct setting for the infusion pump should be 60 mL/hour to deliver 30 mL in 30 minutes. To calculate the infusion rate in mL/hour, divide the total volume to be infused (30 mL) by the total time for infusion (30 minutes) and then multiply by 60 to convert minutes to hours. Therefore, 30 mL / 30 minutes * 60 minutes/hour = 60 mL/hour. Choices B, C, and D are incorrect because they do not match the calculation based on the given parameters.

Correct Answer: A

Rationale: Varicella (chickenpox) is an airborne infectious disease, requiring isolation to prevent the spread of the virus.

Correct Answer: C

Rationale: FTT classified as defective utilization is often related to conditions like congenital infections, which interfere with the body's ability to effectively use nutrients. Conditions like cystic fibrosis and hyperthyroidism can also contribute to FTT but are categorized differently
