The nurse is conducting a well-child examination of a 5-year-old girl, who was 40 in 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 in. This is within the expected range of growth for a preschooler based on the average growth rate of 2.5 inches per year. At age 4, the girl was 40 inches tall, so at age 5, she would be expected to be around 42.5 inches tall. Therefore, a height measurement of 43 inches falls within the normal range of growth.

Choice A (47 in) is too tall for a child of this age, exceeding the expected growth rate. Choice B (41 in) is slightly below the expected growth rate. Choice C (45 in) is above the expected range for a 5-year-old. These choices do not align with the typical growth patterns for a preschooler, making them incorrect.
