NR 509 Exam 3 – Chamberlain Advanced Physical Assessment: 300 Practice Questions & Detailed
1
Rationales
,Q1
A patient is asked to move his arm toward the center of his body. This movement is called:
A) Flexion
B) Abduction
C) Adduction CORRECT
D) Extension
Rationale
** Adduction is movement toward the midline of the body. Abduction is movement away from midline.
Flexion decreases the angle at a joint; extension increases it.
Q2
A patient reports difficulty bringing her hand to her mouth to eat or brush her teeth. To perform
this movement, she must perform which motion?
A) Flexion
B) Abduction
C) Adduction
D) Extension
Rationale
** Flexion decreases the angle at the elbow, bringing the hand toward the mouth. This is the correct
movement for hand-to-mouth motion.
Q3
The functional units of the musculoskeletal system are the:
A) Joints CORRECT
B) Bones
C) Muscles
D) Tendons
2
,Rationale
** Joints are the functional units of the musculoskeletal system because they are where movement
occurs. Bones provide structure, muscles produce force, and tendons attach muscle to bone.
Q4
Hematopoiesis takes place in the:
A) Liver
B) Spleen
C) Kidneys
D) Bone marrow CORRECT
Rationale
** Hematopoiesis (blood cell formation) occurs in the bone marrow. The liver and spleen have
hematopoietic roles in fetal life, but after birth the bone marrow is the primary site.
Q5
Fibrous bands running directly from one bone to another that strengthen the joint and prevent
undesirable movement are called:
A) Bursa
B) Tendons
C) Cartilage
D) Ligaments CORRECT
Rationale
** Ligaments connect bone to bone and provide joint stability, preventing excessive or undesirable
movement. Tendons connect muscle to bone; bursae are fluid-filled sacs that reduce friction; cartilage
covers joint surfaces.
Q6
An imaginary line connecting the highest point on each iliac crest crosses which vertebra?
A) First sacral
3
, B) Fourth lumbar CORRECT
C) Seventh cervical
D) Twelfth thoracic
Rationale
** The line connecting the iliac crests (Tuffier's line) typically crosses the L4 vertebra. This is a key
landmark for lumbar puncture and spinal anesthesia.
Q7
The shock absorbers of the spine that cushion vertebrae and help the spine move are the:
A) Vertebral column
B) Nucleus pulposus
C) Vertebral foramen
D) Intervertebral disks CORRECT
Rationale
** Intervertebral disks are fibrocartilaginous cushions between vertebrae that absorb shock and allow
spinal movement. The nucleus pulposus is the gel-like center of the disk.
Q8
A rotator cuff injury involves which joint?
A) Nucleus pulposus
B) Articular processes
C) Medial epicondyle
D) Glenohumeral joint CORRECT
Rationale
** The rotator cuff is a group of muscles and tendons that stabilize the glenohumeral (shoulder) joint.
Injury to these structures affects shoulder movement and stability.
