A nurse expects to hear which percussion sounds over muscles and tissues?
Flatness.
Dullness.
Tympany.
Resonance.
The Correct Answer is A
Choice A rationale
Flatness is the percussion sound typically heard over muscles and solid tissues. It is characterized by a high-pitched, soft sound, which indicates that the underlying tissue is denser and less air-filled compared to lungs.
Choice B rationale
Dullness is heard over solid organs such as the liver or spleen but not typically over muscles.
Choice C rationale
Tympany is a drum-like sound heard over areas filled with gas, such as the stomach or intestines.
Choice D rationale
Resonance is heard over air-filled lungs and not over muscles and solid tissues.

Correct Answer is B
Explanation
Choice A rationale
Lateralization to the unaffected ear in Weber's test actually indicates sensorineural hearing loss in the affected ear. This choice is incorrect as it doesn’t describe the correct procedure for the test.
Choice B rationale
The Weber's test involves placing an activated tuning fork in the midline of the skull and asking the patient if the sound is heard more loudly in either ear. This helps determine if there is lateralization, which is key in diagnosing the type of hearing loss. Thus, this is the correct procedure for the test.
Choice C rationale
Placing the tuning fork on the mastoid bone and then over air is actually part of the Rinne test, not the Weber test. This choice is, therefore, incorrect for the Weber test.
Choice D rationale
Similar to Choice C, this process describes the Rinne test, which compares air conduction and bone conduction of sound. This is not the correct method for performing Weber’s test.
