Question 5

Subcostal plane (location)

Answer 5

Axial plane at the level of the inferior most aspects of the costal margins

Question 6

Diaphragm (location)

Answer 6

Composed of two domes that meet at the xihisternal junction and peak at the midclavicular line (right side: just below the nipple at the 5th rib; left side: 2-3cm below the nipple at the 5th intercostal); meets the costal margin at the midaxillary line

Question 7

Enlarged gallbladder (location)

Answer 7

Intersection of the costal margin and transpyloric plane (near the intersection of the midclavicular line and costal margin)

Question 8

Abdominal aorta (location)

Answer 8

Crosses the diaphragm at T12 (inferred from xiphisternal junction (T9/T10) and the transpyloric plane (L1/L2)), lies just left of midline and ends at L4 (just below umbilicus)

Question 9

Bifurcation of Aorta

Answer 9

L4

Question 10

Renal arteries (location)

Answer 10

Either side of the aorta at the transpyloric line

Question 11

McBurney point (define)

Answer 11

Location of the base of the appendix, junction of the ileum and cecum (ascending colon)

Question 12

McBurney point (location)

Answer 12

One third the distance from the right anterior iliac spine to the navel

Question 13

Isthmus of thymus (location)

Answer 13

Crosses trachea at the level of the 2nd/3rd tracheal rings

Question 14

Isthmus of thymus (location)

Answer 14

Crosses trachea at the level of the 2nd/3rd tracheal rings

Question 15

Heart (border location)

Answer 15

Apex: 5th or 6th intercostal space just medial to the left midclavicular line
Inferior border: Apex to 1cm right of the sternum
Right border: from inferior border end, parallel to the sternum to the 3rd intercostal space
Superior border: from 1cm right of the sternum at the 3rd intercostal space to 2cm left of the sternum

Question 16

Arch of the aorta (location)

Answer 16

Starts between the midline and right margin of the sternum, moves right to 0.5 cm right of the sternum then arches through the middle of the manubrium

Question 17

Answer 17

Sternal angle

Question 18

Order of cardiac valves

Answer 18

From left 3rd costosternal joint toward midline at the xiphisternal junction: Pulmonary, aortic, mitral, tricuspid

Answer 21

Just left of the xiphoid process

Question 22

Auscultation location of mitral valve

Answer 22

Apex of the heart (5th or 6th intercostal space medial to the left midclavicular line)
