In which position would the nurse place a 20 year old adult with asthma who is short of breath?
Supine
Trendelenberg
High-Fowler
Semi-Fowler
Left-lateral
The Correct Answer is C
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.

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.
Correct Answer is C
Explanation
A. The closure of the pulmonic and mitral valves corresponds to heart sound S1, not S2.
B. The tricuspid and mitral valves close with S1.
C. Heart sound S2 represents the closure of the aortic and pulmonic valves, signaling the end of systole and the beginning of diastole.
D. The mitral valve closes with S1, not S2.
E. The pulmonic and tricuspid valves do not correspond with S2.
