The nurse is observing the lung auscultation technique of a student nurse. What is the correct method to use when progressing from one auscultatory site to another?

Posterior to anterior comparison

Side-to-side comparison

Interspace-by-interspace comparison

Proximal to distal comparison

Top-to-Bottom comparison

Answer and Explanation

The Correct Answer is B

A. While posterior to anterior comparisons are used, they do not encompass the entire technique for auscultation.
B. Side-to-side comparison is the correct method as it allows for immediate assessment of differences between lung fields and helps to identify abnormal sounds effectively.
C. Interspace-by-interspace comparison is not a commonly recognized term for this method and can lead to confusion in technique.
D. Proximal to distal comparison is not specific to lung auscultation and does not effectively apply to lung assessment.
E. Top-to-bottom comparison may miss abnormalities in a specific region of the lungs; side-to-side is preferred.

Correct Answer is C

Explanation

A. Supine is not recommended, as it can make breathing more difficult by limiting chest expansion.
B. Trendelenberg is not suitable for someone with breathing difficulties, as this position can worsen dyspnea.
C. High-Fowler is the best position for an asthma patient experiencing shortness of breath as it promotes lung expansion and allows for maximum chest wall movement.
D. Semi-Fowler may help but is less effective than High-Fowler in cases of acute respiratory distress.
E. Left-lateral does not optimize chest expansion and is not typically recommended for respiratory distress.

A. Closure of mitral and aortic valves B. Closure of mitral and tricuspid valves C. Closure of pulmonic and tricuspid valves D. Closure of pulmonic and aortic valves E. Closure of aortic and tricuspid valves

Correct Answer is B

Explanation

A. This option incorrectly includes the aortic valve rather than the tricuspid valve in the S1 heart sound.
B. S1 represents the closure of the mitral and tricuspid valves, which occurs at the beginning of ventricular systole and produces the "lub" sound.
C. The pulmonic valve closure is associated with the S2 heart sound, not S1.
D. The closure of the pulmonic and aortic valves occurs in S2, not S1.
E. This combination is incorrect, as S1 is associated with mitral and tricuspid valve closure.
