During the Assessment of a Patient, a Student Nurse Hears

During the assessment of a patient, a student nurse hears heart tones on the right side of the chest and notices there is a murmur that radiates from the area near the right nipple into the right axilla. She concludes:

A) That the patient has inverted internal organs ("situs inversus") .
B) That her stethoscope needs to be readjusted. She was listening with the bell instead of the diaphragm.
C) That everything is ok. This is a normal finding.
D) That the patient has aortic regurgitation.
