To assess for the presence of egophony, which instruction should the nurse give the client who has a lung abscess?

Choice A reason: Egophony is assessed by asking the client to say "E" while auscultating the chest. If consolidation is present, the sound changes to an "A" quality, indicating abnormal lung density. Choice B reason: Whispered pectoriloquy is assessed using this instruction, not egophony. It evaluates the transmission of whispered sounds through lung tissue. Choice C reason: This instruction is used for general auscultation of breath sounds but does not assess vocal resonance or egophony. Choice D reason: This technique is used to assess bronchophony, not egophony. It helps detect increased transmission of vocal sounds due to lung consolidation.
