A male client arrives at the clinic for follow-up health assessment after recent antibiotic treatment for pneumonia without hospitalization. Which technique should the nurse implement to assess for adventitious lung sounds?

Have the client lay flat while listening to the anterior surface of the chest.

Use the bell of the stethoscope to listen to the lung fields over lower lobes.

Shave all chest hair that may distort sounds heard through the diaphragm.

Press the stethoscope's diaphragm firmly on the skin over each lung field.
