Question

a systolic murmur heard loudest at the right 2nd intercostal space with delayed carotid upstroke most likely indicates
mitral valve regurgitation
aortic stenosis
tricuspid regurgitation
aortic dissection
question 12 (2 points)
during percussion of the liver along the mid - clavicular line, you measure a liver span of 16 cm. what is the normal range for liver span?
4 - 6 cm
6 - 10 cm
10 - 12 cm
12 - 15 cm

Explanation:

1. For the first question, a systolic murmur heard loudest at the right 2nd intercostal space with a delayed carotid upstroke is a classic finding of aortic stenosis. Mitral valve regurgitation has a murmur typically at the apex, tricuspid regurgitation has a murmur at the lower left sternal border, and aortic dissection is not characterized by such a murmur.
2. For the second question, the normal liver span measured along the mid - clavicular line is 6 - 12 cm in adults. Among the given options, 6 - 10 cm is within the normal range.

Answer:

1. B. Aortic stenosis
2. B. 6 - 10 cm
