The nurse is preparing to measure the length, weight, chest, and head circumference of a 6-month-old infant. Which measurement technique is correct?

A) Measuring the infant's length by using a tape measure
B) Weighing the infant by placing him or her on an electronic standing scale
C) Measuring the chest circumference at the nipple line with a tape measure
D) Measuring the head circumference by wrapping the tape measure over the nose and cheekbones

To measure the chest circumference, the tape is encircled around the chest at the nipple line. The length should be measured on a horizontal measuring board. Weight should be measured on a platform-type balance scale. Head circumference is measured with the tape around the head, aligned at the eyebrows, and at the prominent frontal and occipital bones-the widest span is correct. The height or length of an infant until 2-years-old should be measured on a horizontal measuring board, not using a tape measure. Weight of a 6-month-old should be measured on a platform-type balance scale. Head circumference is measured with the tape around the head, aligned at the eyebrows, and at the prominent frontal and occipital bones, not over the nose and cheekbones.
