4. Which of the following best describes the logical order in which auscultations should be made during a cardiac examination? A. Pulmonary, Aortic , tricuspid and mitral B. Aortic, Pulmonary , tricuspid and mitral C. Pulmonary, Aortic , mitral and tricuspid D. Aortic, pulmonic mitral and tricuspid

The correct answer is B. Aortic, Pulmonary, tricuspid, and mitral.<br /><br />During a cardiac examination, auscultation is performed to listen to the heart sounds. The logical order in which auscultations should be made is based on the anatomical location of the heart valves and the direction of blood flow.<br /><br />The correct order is:<br />1. Aortic valve: The aortic valve is located between the left ventricle and the aorta. Auscultation is performed at the right second intercostal space at the right sternal border.<br />2. Pulmonary valve: The pulmonary valve is located between the right ventricle and the pulmonary artery. Auscultation is performed at the left second intercostal space at the left sternal border.<br />3. Tricuspid valve: The tricuspid valve is located between the right atrium and the right ventricle. Auscultation is performed at the left fourth intercostal space at the left sternal border.<br />4. Mitral valve: The mitral valve is located between the left atrium and the left ventricle. Auscultation is performed at the left fifth intercostal space at the left midclavicular line.<br /><br />This order is important because it allows the examiner to systematically assess the function of each valve and identify any abnormal heart sounds or murmurs.
