A nursing student is preforming a head-to-toe assessment on his patient with a history of mitral regurgitation. Instead of hearing normal heart sounds the student hears a murmur.

Which of the following best describes the sound of a heart murmur?

A. Assess the pedal pulses with a Doppler device:

Assessing the pedal pulses with a Doppler device may be useful in certain situations, but when the radial pulse is irregular, it's more important to assess the central (apical) pulse to get a more accurate representation of the heart's rhythm.

B. Assess the apical pulse with a Doppler device:

While using a Doppler device on the apical pulse is an option, it's generally not the first choice when assessing irregular pulses. The apical pulse can often be palpated manually, and it's more practical to assess it directly for irregularities.

C. Assess the apical pulse for a full minute:

This is the recommended action when the radial pulse is irregular. By assessing the apical pulse for a full minute, the nurse can accurately determine the heart rate and identify any irregularities in rhythm, providing a comprehensive assessment of the cardiac status.

D. Assess the pedal pulses for a full minute:

While assessing the pedal pulses is important in certain situations, it may not be the priority when dealing with an irregular radial pulse. Assessing the apical pulse for a full minute gives a more direct and accurate reflection of the heart's rhythm.

A. Skin fold:

This may not be the best choice in this situation because the skin fold might not provide an accurate reading, especially if the hands are edematous.

B. Toe:

While the toe is a common site for pulse oximetry, in a patient with bilateral lower leg amputations, it might not be the most practical option. The nurse might face challenges in securing the pulse oximeter probe on the toe, and the accuracy of the reading could be affected.

C. Earlobe:

This is often a suitable alternative site for pulse oximetry when peripheral perfusion is compromised in the extremities. In this case, with bilateral lower leg amputations and edematous hands, applying the pulse oximeter probe to the earlobe is a good choice.

D. Finger:

In a patient with edematous hands, the finger might not be the best choice as the edema could affect the accuracy of the measurement. Additionally, if the patient has lower leg amputations, using the earlobe or another alternative site may be more appropriate.
