A nurse is performing a physical assessment for a preschooler. Which of the following actions should the nurse take?

A. Auscultate the abdomen for at least 1 min if bowel sounds are absent. This is an appropriate action. Absence of bowel sounds can indicate a serious condition, so the nurse should auscultate for at least 1 minute to confirm their absence. However, it is generally recommended to listen for up to 5 minutes before concluding that bowel sounds are absent.B. Use the bell stethoscope to auscultate breath sounds. The diaphragm of the stethoscope, not the bell, is typically used to auscultate breath sounds because it is better at picking up higher-pitched sounds like those of the lungs.C. Check visual acuity by using the tumbling E eyechart. The tumbling E chart is appropriate for pre-schoolers who may not know the alphabet. This chart helps assess visual acuity in young children by having them identify the direction of the E's legs.D. Place hand on the pre-schooler’s abdomen to determine respiratory rate. Placing a hand on the abdomen can help in counting the respiratory rate in infants and very young children who are diaphragmatic breathers, but for pre-schoolers, it is typically easier and more accurate to count respirations by observing the chest rise.
