RASMUSSEN UNIVERSITY
Bachelor of Science in Nursing (BSN)
MDC 1 - Multidimensional Care I
Academic Year: 2026/2027
Exam 2 Review - Musculoskeletal & Sensory Disorders
Question 1
Osteoclasts are cells that perform which function?
A. Build new bone tissue
B. Break old bone tissue (resorption)
C. Store calcium in the bone matrix
D. Produce red blood cells
CORRECT ANSWER B. Break old bone tissue (resorption)
RATIONALE
Osteoclasts are responsible for bone resorption (breaking down old bone tissue). Osteoblasts
build new bone. This remodeling process maintains calcium homeostasis and bone strength.
,Question 2
Which joints are examples of hinge joints? (Select all that apply)
A. Shoulder
B. Knee
C. Elbow
D. Hip
CORRECT ANSWER
B, C. Knee and elbow are hinge joints (flexion/extension only). Shoulder and hip
are ball-and-socket joints.
RATIONALE
Hinge joints allow movement in one plane (flexion/extension). Examples: knee, elbow,
interphalangeal joints. Ball-and-socket joints (shoulder, hip) allow multi-directional movement.
Question 3
The ability to carry out activities of daily living is known as:
A. Flexibility
B. Fitness
C. Strength
D. Endurance
CORRECT ANSWER B. Fitness
RATIONALE
Fitness refers to the ability to perform physical activities and ADLs. It encompasses strength,
endurance, flexibility, and cardiovascular health necessary for daily function.
, Question 4
True or False: Not bending forward at the waist or neck is a good way to maintain
proper posture.
A. True
B. False
CORRECT ANSWER A. True
RATIONALE
Proper posture involves keeping the spine in a neutral alignment. Avoiding excessive forward
bending at the waist or neck helps prevent strain on spinal structures and maintains good
posture.
Question 5
True or False: Using high-heels helps with posture.
A. True
B. False
CORRECT ANSWER B. False
RATIONALE
High heels alter normal alignment, shifting the center of gravity forward, increasing lumbar
lordosis and stress on the lower back. They are detrimental to proper posture and increase fall
risk.
