A nurse assesses the height and weight measurements on an infant and documents these measurements at the 75th percentile. The nurse notes that the previous measurements two months ago were at the 25th percentile. How should the nurse interpret these data?
1. The infant is not gaining enough weight.
2. The infant has gained a significant amount of weight.
3. The previous measurements were most likely inaccurate.
4. These measurements are most likely inaccurate.

Correct Answer: 2
Rationale 1: A comparison of these two sets of measurements shows that the infant has crossed two percentiles going from the 25th to the 75th percentile and therefore has gained a significant amount of weight. There is no indication that the previous measurements are inaccurate nor that the current measurement is inaccurate.
