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

A. Repeat the number "99": This test is for bronchophony, not egophony. B. Whisper "one, two, three": This tests for whispered pectoriloquy. C. Repeat vocalizing the letter "E": Egophony is assessed by having the client say "E" while auscultating the thorax. In areas of lung consolidation (e.g., a lung abscess), "E" sounds may be heard as "A." D. Breathe in and out: This assesses general breath sounds, not egophony.
