Answer to Question 1
ANS: A, C, D
As a patient repeatedly says ninety-nine, normally the examiner hears voice sounds but cannot distinguish what is being said. If a clear ninety-nine is auscultated, then it could indicate increased lung density, which enhances the transmission of voice sounds, which is a measure of bronchophony. When a patient says a long ee-ee-ee sound, normally the examiner also hears a long ee-ee-ee sound through auscultation, which is a measure of egophony. If the examiner hears a long aaaaaa sound instead, this sound could indicate areas of consolidation or compression. With whispered pectoriloquy, as when a patient whispers a phrase such as one-two-three, the normal response when auscultating voice sounds is to hear sounds that are faint, muffled, and almost inaudible. If the examiner clearly hears the whispered voice, as if the patient is speaking through the stethoscope, then consolidation of the lung fields may exist.
Answer to Question 2
ANS: C
Hypoventilation is characterized by an irregular, shallow pattern, and can be caused by an overdose of narcotics or anesthetics. Bradypnea is slow breathing, with a rate less than 10 respirations per minute.
