Correct Answer is A
Explanation
A. Prevent distortion of bowel sounds. – Palpation can stimulate peristalsis and alter bowel sounds, leading to inaccurate assessment findings.
B. Prevent distortion of vascular sounds. – While palpation might affect vascular sounds slightly, this is not the primary concern when assessing the abdomen.
C. Determine any areas of tenderness or pain. – While assessing for tenderness is important, auscultation precedes palpation primarily to avoid altering bowel sounds.
D. Allow the patient to relax and be comfortable. – While relaxation is beneficial, the sequence of assessment is based on maintaining accuracy in findings rather than patient comfort.
Correct Answer is C
Explanation
A. Opening of the AV valves – The AV (atrioventricular) valves open silently during diastole; they do not create the "lub" sound.
B. Closing of the semilunar valves – The closing of the semilunar valves (aortic and pulmonary) produces the "dupp" sound, not the "lub."
C. Closing of the AV valves – The first heart sound (S1), or "lub," occurs when the mitral and tricuspid (AV) valves close at the beginning of systole.
D. Opening of the semilunar valves – The semilunar valves open silently during ventricular contraction; they do not produce the "lub" sound.
