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. Measure the infant's length from the crown of the head to the heels of the feet: Infant length should be measured with the infant lying flat, from the top of the head (crown) to the heels, using a measuring board or tape. B. Ensure the scale is balanced to "0" before weighing the infant: Calibrating the scale to zero ensures an accurate measurement. Weighing without zeroing first can result in an incorrect reading. C. Place a stadiometer on the top of the infant's head to measure their length: A stadiometer is used for standing height in older children and adults. It is not appropriate for infants who cannot stand independently. D. Cover the scale with a clean sheet of paper: Covering the scale maintains cleanliness and helps prevent cross-contamination between patients, which is essential in pediatric settings. E. Obtain the infant's weight with their diaper on: For accurate weight, the infant should be weighed without clothing or diapers, as these can add extra ounces and distort the measurement.
