WGU D115 2026 COMPREHENSIVE EXAM
SCRIPT COMPLETE ANSWER SET
◉Describe the most likely route by which the microorganisms
reached the patient's bone.
Submit and Compare, displayed below. Answer: The microorganisms
likely reached her bone by extension from the nearby infected ulcer
at the base of her big toe.
◉Name the microorganism that is most likely causing the
osteomyelitis.
Submit and Compare, displayed below. Answer: staphylococcus
aureus is the most common pathogen, although many diabetic foot
ulcers are polymicrobial infections.
◉Describe sequestrum.. Answer: Sequestrum is an area of necrotic
bone that separates from the healthy bone.
◉What is the most common cause of a corner metaphyseal fracture
in a child younger than 12 months of age?. Answer: A transverse
tibia fracture resulting in a straight horizontal break across the tibial
shaft is a common cause of a corner metaphyseal fracture in a child
under 12 months of age. A transverse fracture is caused by direct
force, often involving the metaphysis, and is considered a sign of
, suspected physical abuse, though transverse fractures could be
caused by other types of trauma. A spiral fracture, caused by a
twisting force, also often involves the metaphysis and is also a sign
of suspected physical abuse.
◉Evaluation of osteogenesis imperfecta. Answer: hould include
genetic testing, bone scans, and bone density testing. Osteogenesis
imperfecta is a disorder caused by a genetic mutation in the gene
that encodes for type I collagen, the main component of bone and
blood vessels. The Sillence classification defines four types. Types I
and IV are milder forms and are inherited in an autosomal dominant
pattern. Types II and III are more severe and are inherited in a
recessive pattern. The classic clinical manifestations of osteogenesis
imperfecta are osteopenia and an increased rate of fractures. Type
IV can be subtle with more normal stature and fractures, often not
occurring until children are older; however, it can be misdiagnosed
as child abuse.
◉The medical treatment for osteogenesis imperfecta. Answer:
involves increased calcium and vitamin D. Pamidronate and other
bisphosphonates, such as alendronate (Fosamax) which decrease
bone resorption by inhibiting osteoclasts, are now frequently used.
◉What is the most common type of skin cancer?. Answer: Basal cell
carcinoma is the most common type of skin cancer.
◉Which skin infection is caused by a virus?
