Chapter 12: Musculoskeletal Flashcards
Where is osteoarthritis most common?
hips, knees, hands
What is osteoarthritis?
Localized joint disease - deterioration of articulating cartilage and underlying bone degenerative joint disease, inflamed synovial lining, weakened muscles, bone erosion
Loss of proteoglycans ( provides structural support to the extracellular matrix as well as surrounding tissues and organs. Their affinity to water also provides cushion, protection, and a source of hydration)
The APRN is providing education to patient who was recently diagnosed with Osteoarthritis? Which statement by the APRN is correct?
A. Osteoarthritis is commonly seen in thin, small-built females
B. Osteoarthritis is a result of joint inflammation
C. Osteoarthritis occurs due to erosion of cartilage in the joints
D. Osteoarthritis is a metabolic bone disease
C. Osteoarthritis occurs due to erosion of cartilage in the joints.
complications of a femur fracture
fat embolism, compartment syndrome
complication of displaced fracture
osteonecrosis
complication of open fracture
osteomyelitis
. Which of the following is a symptom of carpal tunnel syndrome?
sweaty palms
pain that is worse during the daytime
numbness in fingers
finger stiffness
numbness in fingers
True or False:
A patient with carpal tunnel syndrome will likely experience pain when trying to make a fist.
false; patients with carpal tunnel will have numbness/tingling/pain at night and when flexing/extending the wrist or raising the arm
thickening and contracture of palmar fascia d/t fibroblast proliferation and abnormal collagen deposition
DUPUYTREN CONTRACTURE (a.k.a. Palmar Fibromatosis)
painless nodule and thickening over affected area, starting at metacarpophalangeal joint, but can progress to proximal interphalangeal joint
limited flexion
abnormal thickening of flexor (palmar) tendon at the metacarpophalangeal joint
affected finger locks during flexion
TRIGGER FINGER (a.k.a. Stenosing Flexor Tenosynovitis)
inflammation and swelling of wrist tendons on radial side, can compress nerves
moving affected wrist/thumb or making a fist (Finkelstein maneuver) causes pain.
de Quervain Tendinopathy (a.k.a. Stenosing Tenosynovitis)
compression of the median nerve as it travels into the carpal tunnel space in the wrist.
Cause is unclear but seems to be related to anatomy or inflammation, and it eventually leads to nerve ischemia.
Carpal tunnel syndrome
Progressive loss of bone strength due to low bone mass and quality, leading to increase risk of fractures
secondary is less common (caused by endocrine disorders e. diabetes and thyroid disorders)
osteoporosis
aging increase osteocyte apoptosis resulting spongy bone becoming more fragile
Intervertebral disk issues
disks begin to degenerate
Spondylosis
narrow disk space seen on imaging
Why would a patient with muscular dystrophy appear to have increased muscle mass?
muscular dystrophy is characterized by muscle weakness and atrophy, but pseudohypertrophy can occur d/t fat and connective tissue deposits in place of muscle

- A pathologic stress fracture occurs in bones subjected to:
A) sudden direct force.
B) weakening by disease.
C) repeated excessive use.
D) massive muscle contraction.
B) weakening by disease.
- Shortly after a closed fracture has occurred, early manifestations include localized:
A) tetany.
B) deformity.
C) necrosis.
D) numbness.
D) numbness.
- In order to initiate the cellular events essential to bone healing, there must be
formation at the fracture site.
A) callous
B) hematoma
C) ossification
D) fibrin meshwork
B) hematoma
- In contrast to structural scoliosis, postural scoliosis:
A) compresses vertebrae.
B) corrects with bending.
C) is apparent at birth.
D) becomes painful.
B) corrects with bending.
- Factors that may adversely affect bone healing include of the bone.
A) immobilization
B) weight bearing
C) delayed union
D) tight alignment
C) delayed union
- The distinguishing characteristic of chronic osteomyelitis is the presence of:
A) sequestrum bone.
B) abscess formation.
C) severe bone pain.
D) external drainage.
A) sequestrum bone.
sequestrum is a piece of dead bone that has separated from healthy bone
- Developmental dysplasia of the hip (DDH), formerly known as congenital hip dislocation, is suspected when an infant has:
A) gluteal fold asymmetry.
B) lengthening of the thigh.
C) joint capsule tightness.
D) delay of knee crawling.
A) gluteal fold asymmetry.
- Osteonecrosis is most often caused by:
A) stress fractures.
B) bacterial infection.
C) synovial inflammation.
D) bone marrow ischemia.
D) bone marrow ischemia.
10 The patient has a fractured tibia. After the cast is applied he is at high risk
. for compartment syndrome caused by:
A) inflammation.
B) joint immobility.
C) muscle atrophy.
D) extremity elevation.
A) inflammation.
11 A college baseball player has seen his season cut short by a rotator cuff
. injury. Rotator cuff injuries are frequent because of:
A) the inherent instability of the shoulder.
B) the absence of ligaments at the glenohumeral joint.
C) the vulnerability of the shoulder menisci.
D) the large mass of the humeral head.
A) the inherent instability of the shoulder.
12 A patients clavicular fracture has healed in the weeks following a bicycle
. accident. Which of the following events takes place in the remodelling stage of bone healing?
A) Formation of granulation tissue
B) Development of fibrocartilage that resembles the appearance of the original bone

D) Reduction in the size of the callus
13 A child has been hospitalized for the treatment of hematogenous
. osteomyelitis. The defining characteristic of this type of osteomyelitis is:
A) the presence of dead bone tissue.
