To determine the quality and intensity of a cardiac murmur, the nurse would take which action?
Use the bell of the stethoscope
Palpate the chest wall to feel the intensity of the murmur
Use a Doppler ultrasound device
Percuss the thorax cavity
The Correct Answer is A
A. The bell of the stethoscope is best used to listen for low-pitched sounds, including some types of murmurs, and can help assess the quality and intensity of a cardiac murmur.
B. While palpation can provide some information about the heart's function (such as thrills), it is not the primary method for assessing the quality of a murmur.
C. A Doppler ultrasound device is used for measuring blood flow and can help in assessing murmurs but does not provide the quality assessment needed for characterizing a murmur.
D. Percussion is not typically used to evaluate murmurs; it is more useful for assessing the size and borders of organs.
