Correct Answer: B

Rationale: Heating formula in a plastic bottle in the microwave can cause uneven heating and release harmful chemicals from the plastic.

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

Correct Answer: A

Rationale: The correct answer is A: 60 mL/hour. The total volume to be infused is 30 mL over 30 minutes. To calculate the infusion rate in mL/hour, divide the total volume by the total time in hours. In this case, 30 mL / 0.5 hours = 60 mL/hour. Choice B, 45 mL/hour, is incorrect as it does not correspond to the calculated infusion rate. Choices C and D, 30 mL/hour and 15 mL/hour respectively, are also incorrect based on the calculation.

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: A

Rationale: To calculate the dosage, multiply the child's weight (10 kg) by the dosage (8 mg/kg) which equals 80 mg. Since the concentration is 100 mg/5 mL, to find out how much to administer, you need to determine how many 5 mL doses are in 80 mg. It will be 80 mg · 100 mg * 5 mL = 4 mL. Therefore, the correct answer is 4 mL. Choice B, 2 mL, is incorrect because it does not account for the correct dosage calculation. Choice C, 5 mL, is incorrect as it does not consider the dosage based on the child's weight. Choice D, 3 mL, is incorrect as it does not reflect the accurate dosage calculation.
