The nurse is assessing the lung sounds of a preschooler. Which action should the nurse implement to ensure the child's cooperation?

To ensure the cooperation of a preschooler during an assessment of lung sounds, the nurse can allow the child to use a stethoscope on a stuffed animal. This helps the child understand what is happening and feel more comfortable with the procedure. Having the child blow a cotton ball (A), placing a toy in the child's hands (B), and offering bubbles (C ) may distract the child but do not directly involve them in the procedure.
