a. articular cartilage.
b. epiphyseal plate.
c. cortex of compact bone.
d. medullary cavity of the diaphysis.
2. The IO space can absorb fluids and medications
a. because it contains many tiny blood vessels.
b. and transport them to the peripheral circulation.
c. for patients in resuscitative states.
d. despite any compromise of the bone.
3. Compared with peripheral veins, the IO space
a. absorbs medications slowly.
b. allows nontraumatic access.
c. is a less successful vascular access method.
d. does not collapse with dehydration.
4. Manual IO insertion devices use a removable trocar inside the needle to

d. uses a spring-loaded mechanism.
7. In pediatric patients, the preferred placement site is the

a. allows gentle manipulation to improve flow.
b. sits firmly on the bone.
c. does not require an IV pump.
d. demonstrates brisk blood flow with aspiration.
10. A study using an IO power driver to achieve vascular access resulted in successful insertion and infusion in what percentage of the patients studied?
11. Of the following, extravasation of IO-infused fluids is most likely to result from
a. repeated IO attempts at the same site.
b. hypotonic fluid infusion.
c. high-volume fluid infusion.

a. fat embolism.
b. compartment syndrome.
d. catheter dislodgment.
13. Study findings indicate that clinicians can prevent osteomyelitis by removing the IO needle within how many hours of insertion?
14. The pain associated with IO vascular access is typically a direct result of
a. site preparation.
