Rasmussen College MDC 1 Exam 2 Questions and
Answers (2024-2025) (Verified Answers)
What factors affect mobility? - ANSWER >>> Developmental age,
nutritional status, lifestyle choices, stress, environment, and diseases.
What are some diseases that affect mobility? - ANSWER >>>
Rheumatoid arthritis, osteoarthritis, osteoporosis, ankylosing
spondylitis, gout, osteoporosis, osteomyelitis, and bone tumors.
What is Rheumatoid Arthritis and some clinical manifestations? Most
frequent in? - ANSWER >>> It is systemic autoimmune disease
causing chronic inflammation of the joints and connective tissue.
C/S: Causes pain, deformities, fever, fatigue, weakness, weight loss
and loss of function.
Most frequent in mid-life age and females.
What is osteoarthritis and some clinical manifestations? Most frequent
in? - ANSWER >>> Loss of articular cartilage in the joint.
C/S: · Causes pain, stiffness, crepitus, aggravated weight-bearing and
joint use.
Most frequent in females.
What is Ankylosing Spondylitis? - ANSWER >>> Chronic
inflammatory joint disease that causes stiffens and fusion of the spine
and sacroiliac joints
What is Gout? - ANSWER >>> Inflammatory response to high-levels
of uric acid. Forms tophi (white nodules) in the synovial fluid.
,What is Osteoporosis? Most Common in? Best Treatment? -
ANSWER >>> Decrease in total bone density when osteoclast activity
is higher than osteoblast.
Most common in females at menopause age.
The best treatment is prevention by proper diet high in calcium,
fluoride and minerals.
What is Osteomyelitis? - ANSWER >>> Infection of the bone.
Can develop after injury, surgery or traumas.
What are bone tumors? - ANSWER >>> Affects form and function.
Causes pain and severely impedes mobility.
What is Syndactylism? - ANSWER >>> Fusion on one or more
fingers.
What is developmental dysplasia of the hip (DHH)? - ANSWER >>>
Hip dislocation due to femur abnormality.
What are foot deformities? - ANSWER >>> · Club foot (talipes
equinovarus) can affect walking
What is Scoliosis? - ANSWER >>> Scoliosis: lateral curvature of the
spine.
What is Osteogenesis? - ANSWER >>> Brittle bones that fracture
easily.
What is Achondroplasia? - ANSWER >>> Dwarfism (bones harden
prematurely)
What is Paget's disease? - ANSWER >>> Increased bone loss
results in pain, pathological fractures and deformities
, Vitamin D & Calcium? - ANSWER >>> Porous bones. Prolonged
deficiency can cause bowed, retard growth and frequent fractures of
the long bones.
What are some disorders of the CNS? - ANSWER >>> Disorders that
affect the motor center of the brain.
Ex. Stroke, spinal cord injury, multiple sclerosis, and myasthenia
gravis.
What diseases can occur from other systems besides CNS that can
be affected by mobility? - ANSWER >>> Respiratory disease: Limit
mobility tolerance due to lack of oxygen
Circulatory disorders: Impairs tissue oxygen delivery causing pain,
edema, discomfort, etc.
Fatigue: Limits activity to a short period of time.
Bedrest: reduces overall activity
What are the affects of immobility on the musculoskeletal system? -
ANSWER >>> 12% loss of muscle strength per week
Osteoporosis
Change in calcium metabolism leading to possible formation of renal
calculi
Impaired balance
Foot drop
Altered joint mobility
Pathological fractures
