The scalene muscles lie deep to the sternocleidomastoid, but may be palpated in the posterior
triangle of the neck. These muscles function as a unit to elevate and fix the first and second ribs.
The sternocleidomastoid muscle elevates the sternum.
PTS: 1
8. When the arms and shoulders are fixed, by leaning on the elbows or grasping onto a table, this
muscle can use its insertion as its origin and facilitate an increase in the A-P diameter of the
thorax.
ST
A. Upper trapezius
B. Pectoralis major
C. Sternocleidomastoid
D. Serratus anterior
ANS: B
When the insertion and origin of the pectoralis muscle are reversed by leaning on a table to fix
U
the arms, the muscle will pull on the anterior chest wall, lifting the ribs and sternum to increase
the A-P diameter of the thoracic cage.
PTS: 1

9. The serous fluid within the pleural space serves to provide which of the following functions?
A. Create a constant negative pressure
B. Assist with venous return of blood to the heart
YS
C. Reduce friction between the lungs and thoracic wall
D. Serve to allow separation of the pleural layers
ANS: C
The serous fluid within the pleural space serves to hold the pleural layers together during
ventilation and reduce friction between the lungs and the thoracic wall. The space creates the
negative pressure to maintain lung inflation, not the fluid itself.

PTS: 1
10. Irritation of the phrenic supplied pleura results in which of the following pain referral patterns?
EL
A. Thoracic wall
B. Abdominal wall
C. Mediasternal region
D. Lower neck and shoulder
ANS: D
Irritation of the phrenic supplied pleura can result in referred pain in the lower neck and
F
shoulder, whereas, irritation of the intercostally innervated pleura may result in referral of pain to
the thoracic or abdominal wall.
PTS: 1
11. An abnormal pleural friction rub on auscultation BEST indicates which of the following?
A. Infection with a resultant inflammatory response within the pleura
