Pathophysiology Alterations of Musculoskeletal
Function in Children Huether & McCance Exam
Practice Questions with Verified Solutions
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.
. - Answer 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
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. - Answer ANS: B
, OI (brittle bone disease) is a spectrum of disease caused 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
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. - Answer 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.
Children with osteogenesis imperfecta (OI) are at high risk for frequent:
a.
bone fractures.
b.
shoulder dislocations.
c.
bone infections.
d.
joint injuries. - Answer ANS: A
