During a musculoskeletal examination of the spine, what is the action(s) of the erector
spinae muscle group?
Time Spent - 00:00:08
Your Response:
Extension of the spine
Rationale:The erector spinae muscle group is one of the deep intrinsic muscle groups of the
back that extend the spine. Rotation of the spine is incorrect; the muscles that rotate the spine
are the abdominal muscles and the intrinsic muscles of the back. Flexion of the spine is
incorrect; the muscles that flex the spine are the psoas major and minor, quadratus lumborum,
and the abdominal muscles. Lateral bending of the spine is incorrect; the muscles that laterally
bend the spine are the abdominal muscles and the intrinsic muscles of the back. Rotation and
lateral bending of the spine is incorrect; the muscles that laterally bend the spine are the
abdominal muscles and the intrinsic muscles of the back.

A 62-year-old patient with rheumatoid arthritis (RA) complains of increased joint
stiffness. What characteristic(s) are consistent with her diagnosis of RA?
Time Spent - 00:00:03
Your Response:
Swelling of the synovial tissue is seen in joints and tendon sheaths.
Rationale:The physical signs of RA include frequent swelling of the synovial tissue in joints or
tendon sheaths. Stiffness follows joint activity is incorrect; joint stiffness is usually present after
periods of inactivity in RA. Joint distribution is asymmetrical is incorrect; the distribution of
involved joints is usually symmetrical in RA. It most frequently involves the first
metatarsophalangeal joint is incorrect; the involvement of the first metatarsophalangeal joint is

subcutaneous tissue is typical of chronic tophaceous gout.

An obese 50-year-old patient presents with a long history of back trouble. What structure
in the spine supports the body's weight?
Time Spent - 00:00:07
Your Response:
Vertebral body
Rationale:The vertebral body is a weight-bearing structure of the spine. Vertebral arch is
incorrect; the vertebral arch encloses the spinal cord. Intervertebral disk is incorrect; the
intervertebral disk provides a cushion between the vertebrae. Transverse process and Spinous
process are incorrect; these structures serve as a site of muscle attachment.
