Chapter 40: Alterations of Musculoskeletal Function in ChildrenMULTIPLE CHOICE
1. While performing an assessment of a 2-month-old, the nurse notes a positive Ortolani click.
The nurse would suspect the child has:
a. a hip fracture.
b. hip dysplasia.
c. osteogenesis imperfecta.
d. osteomyelitis.
ANS: B
Ortolani click is symptomatic of developmental dysplasia of the hip. A hip fracture would
be evident by shortening of the leg and external rotation. Osteogenesis imperfecta is
diagnosed by fractures. Osteomyelitis is diagnosed by fever and infection.
REF: p. 1039
2. A 9-month-old was diagnosed with osteogenesis imperfecta (OI). This disease is caused by:
a. uterine teratogens.
b. a genetic defect.
c. malnutrition.
d. trauma.
ANS: B
OI (brittle bone disease) is a NspUecRtrSumINoGf dTisBea.sCe cOaMused by
genetic mutation in the gene that encodes for type I collagen, the main component of bone
and blood vessels.
OI (brittle bone disease) is not due to teratogens, malnutrition, or a fracture.
REF: p. 1039
3. A 9-month-old male was diagnosed with osteogenesis imperfecta (OI). This disease is
caused by errors in the synthesis of:
a. elastin.
b. glycoproteins.
c. collagen.
d. calcium salts.
ANS: C
OI (brittle bone disease) is a spectrum of disease caused by genetic mutation in the gene
that encodes for type I collagen. OI (brittle bone disease) is not caused by faulty synthesis
of elastin, glycoproteins, or calcium salts.
REF: p. 1039

a. bone fractures.
b. shoulder dislocations.
c. bone infections.
, d. joint injuries.
ANS: A
Children with OI experience frequent bone fractures. They are not as susceptible for shoulder
dislocations, bone infections, or other joint injuries.

5. A 1-year-old female was diagnosed with osteogenesis imperfecta (OI). Which
complication must be monitored for?
a. Congestive heart failure
b. Liver failure
c. Aortic aneurysm
d. Pulmonary emboli
ANS: C
Because type I collagen is also the main component of blood vessels, vascular deformity, such
as aortic aneurysm, can occur. Neither congestive heart failure, liver failure, nor pulmonary
emboli are associated with osteogenesis imperfecta (OI).
REF: p. 1039
6. Legg-Calvé-Perthes (LCP) disease affects which of the following joints?
a. Vertebral
b. Shoulder
c. Hip
d. Knee
ANS:
C
LCP affects the hip. This condition is not associated with the vertebrae, the shoulder, or
the knee.
REF: p. 1044
7. Osgood-Schlatter disease causes inflammation of the:
a. shoulder joint.
b. patellar tendon.
c. elbow ligaments.
d. hip cartilage.
ANS: B
Osgood-Schlatter affects the patella, not the shoulder, elbow, or
hip.
REF: pp. 1044-1045
8. Which type of scoliosis accounts for the majority of the cases of scoliosis?
a. Idiopathic
b. Infectious
c. Iatrogenic
d. Secondary
ANS: A
Eighty percent of all scoliosis is idiopathic.
