A nurse is preparing to obtain the length and weight of a 6-month-old infant during a well-child visit. Which of the following actions should the nurse plan to take? (Select all that apply.)

A. Ensure the scale is balanced to "0" before weighing the infant: It is important to calibrate the scale to "0" before weighing the infant to ensure an accurate measurement. This step helps to avoid any errors in weight assessment. B. Place a stadiometer on the top of the infant's head to measure their length: A stadiometer is typically used for measuring height in older children and adults, but for infants, a length board (not a stadiometer) should be used. C. Cover the scale with a clean sheet of paper: This is essential for hygiene and to provide a clean, warm surface for the infant, especially when they are undressed for weighing. D. Obtain the infant's weight with their diaper on: To obtain an accurate weight, the infant should be weighed without the diaper. A diaper adds weight that could affect the accuracy of the measurement. E. Measure the infant's length from the crown of the head to the heels of the feet: For accurate length measurements in infants, the measurement should be taken from the crown of the head to the heels of the feet while the infant is lying flat on a length board.
