Patient Data What can the nurse do to mitigate artifacts when performing auscultation? Select all that apply.

A. Keep the examination room warm, and warm the stethoscope: A warm environment and stethoscope prevent shivering and muscle tension, which can create extraneous sounds during auscultation. B. Wet the chest hair before auscultating: Wetting the chest hair reduces friction between the stethoscope and hair, minimizing "roaring" or rustling sounds that mimic abnormal findings. C. Ensure the room is as quiet as possible: A quiet environment reduces ambient noise, making it easier to hear true breath and heart sounds. D. Reach under a gown to listen and take care that no clothing rubs on the stethoscope: Clothing can produce artifact sounds, so placing the stethoscope directly on the skin ensures a more accurate assessment. E. Document the roaring and crackles: If artifacts are identified as non-physiological (e.g., due to chest hair or external noise), documenting them as findings is inappropriate. The nurse should take measures to mitigate artifacts and re-evaluate.
