The nurse is conducting a well-child examination of a 5-year-old girl, who was 40 inches tall at her last examination at age 4. Which height measurement would be within the normal range of growth expected for a preschooler?

The correct answer is D: 43 inches. This falls within the expected growth range for a 5-year-old girl based on the average growth rate of about 2.5 inches per year. At age 4, she was 40 inches tall, so adding 2.5 inches would make her around 42.5 inches tall at age 5. Therefore, 43 inches is a reasonable and expected height measurement for her age. Choice A (45 inches) and B (47 inches) are too high for a one-year growth period, while choice C (41 inches) is too low based on the average growth rate.
