NON-SYSTEMS NPTE EXAM
QUESTIONS AND ANSWERS
The primary rationale for using a reverse walker instead of a traditional walker is to
improve:
postural alignment
ease of movement
stability
upper extremity involvement - Answer-Correct Answer: postural alignment
A reverse walker is used to facilitate an extension posture for patients that tend to
maintain a flexed posture while standing.
Which assistive device would be most appropriate for maximizing function in a patient
who is partial weight bearing on one lower extremity and is four weeks status post-
bilateral mastectomy?
walking sticks
hemi walker
axillary crutches
Lofstrand crutches - Answer-Correct Answer: Lofstrand crutches
Lofstrand crutches are appropriate when the support of axillary crutches is not needed
or when other factors prove axillary crutches inappropriate. In this case, a history of
bilateral mastectomy has associated axillary lymph node involvement. Excess pressure
in the axillary region would be inappropriate.
What diagnosis would be the most likely to benefit from using a button hook adaptive
device?
Alzheimer's disease
cerebrovascular accident
T10 paraplegia
traumatic brain injury - Answer-Correct Answer: cerebrovascular accident
A button hook adaptive device allows individuals with limited dexterity to button clothing
using a hand held device. This type of adaptive device would be potentially beneficial
for a patient rehabilitating from a cerebrovascular accident due to difficulty with upper
extremity dexterity and coordination.
Which medical imaging technique would best detect an intracranial bleed such as a
stroke?
, computed tomography scan
functional magnetic resonance imaging
positron emission tomography
magnetic resonance imaging - Answer-Correct Answer: computed tomography scan
Computed tomography scans (CT scans) combine multiple x-rays with computer
imaging to examine soft tissues of the body. A CT scan can accurately detect areas of
bleeding based on absorption rates of x-rays.
What technique used to quantify body fat is also used to analyze bone mineral content?
skinfold measurements
bioelectric impedance
dual energy X-ray absorptiometry
hydrostatic weighing - Answer-Correct Answer: dual energy X-ray absorptiometry
Dual energy X-ray absorptiometry (DEXA) uses specialized computers to analyze
penetration of tissues by two rays of differing energies. DEXA is used to quantify
regional body fat, muscle, and bone mineral content. It is most often used to investigate
suspected cases of osteoporosis.
Which scenario is not considered to be a contraindication for magnetic resonance
imaging?
presence of a pacemaker
presence of pins
presence of artificial heart valves
presence of a tumor - Answer-Correct Answer: presence of a tumor
Magnetic resonance imaging (MRI) examines the distribution of hydrogen molecules in
the body in three dimensions. MRIs are used to differentiate types of tissues. They can
be used to examine the brain, tumors, vascular abnormalities, as well as cardiac,
respiratory, and renal conditions. MRIs provide greater contrast of soft-tissue structures
than CT scans.
What are the black areas produced on a radiograph called?
radiodense
radiolucent
radiopaque
radio waves - Answer-radiolucent
Which diagnostic procedure allows direct visual examination of the bladder, ureteral
orifices, and urethra?
x-ray
