Question

question 5 (2 points) which of the following correctly identifies the cause of the s1 heart sound? closure of the semilunar valves opening of the atrioventricular valves closure of the atrioventricular valves rapid ventricular filling question 6 (2 points) what is the expected percussion note over a healthy lung field? dull hyperresonant resonant tympanic

Explanation:

For Question 5, the S1 heart sound is caused by the closure of the atrioventricular valves (mitral and tricuspid valves) at the start of ventricular systole. For Question 6, in a healthy lung field, the expected percussion note is resonant due to the air - filled nature of the lungs which allows for good transmission of sound.

Answer:

Question 5: Closure of the atrioventricular valves
Question 6: Resonant
