Answer to Question 1
ANS: 1
Closure of aortic and pulmonic valves represents S2, or the second heart sound. Some clients with valvular disease have backflow or regurgitation of blood through the incompetent valve, causing a murmur that you can hear on auscultation. During ventricular diastole the atrioventricular (mi-tral and tricuspid) valves open and blood flows from the higher-pressure atria into the relaxed ventricles. This represents S1, or the first heart sound. A murmur is caused by blood turbulence, not coronary artery disease
Answer to Question 2
ANS: 4
Orthopnea is an abnormal condition in which the client uses multiple pillows when lying down or must sit with the arms elevated and leaning forward to breathe. The number of pillows used, such as two or three pillows, usually helps to quantify the orthopnea (e.g., two- or three-pillow or-thopnea).
