statement)

The correct answer is provided directly below each question.
PART I: STRAIGHT ANSWER QUESTIONS (1-45)
1. The imaging modality that uses a magnetic field to induce
changes in proton spin, with tissues releasing weak radio waves
that are measured by a scanner, is:
1. computed tomography
2. magnetic resonance imaging
3. positron emission tomography
4. single photon emission computed tomography
Answer: 2. Magnetic resonance imaging (MRI) uses a magnetic field to
induce changes in proton spin within tissues. Radio waves are emitted at
specific frequencies that make atoms resonate and absorb energy. The
tissues then release a weak radio wave that can be measured by a
scanner.
,2. The procedure that involves insertion of a needle into the
subarachnoid space to inject dye for detecting disc protrusion or
tumors obstructing the spinal canal is called:
1. cisternography
2. myelography
3. lumbar puncture with contrast
4. discography
Answer: 2. Myelography is performed by injecting dye into the
subarachnoid space via lumbar puncture to detect disc protrusion or
tumors that obstruct the spinal canal. It is often combined with CT for
better imaging.
3. The test that measures the electrical activity of muscle fibers
at the time of insertion, at rest, and with voluntary contraction to
diagnose neuropathy and myopathy is:
1. nerve conduction velocity
2. electromyography
3. evoked potentials
4. electroencephalography
Answer: 2. Electromyography (EMG) involves insertion of a needle
electrode into a muscle and recording of electrical activity at insertion, at
rest, and with voluntary contraction. It is used to diagnose neuropathy,
myopathy, and neurodegenerative diseases.
4. The term for the manual process of pouring separated serum
from its collection tube into an identically labeled transport tube,
which can introduce sample identification errors, is:
1. centrifugation
2. aliquoting
3. decanting
4. pipetting
Answer: 2. Transfer of serum from its collection tube to the transport
tube is a manual process called aliquoting. This can introduce error in
sample identification due to a sample being poured into a tube labeled
with another person's identification number.
,5. The condition in which an individual has an A1c level of 6.5% or
greater on two separate occasions is diagnostic of:
1. pre-diabetes
2. diabetes mellitus
3. impaired fasting glucose
4. impaired glucose tolerance
Answer: 2. An A1c level of 6.5% or greater on two separate occasions is
diagnostic of diabetes mellitus. A1c represents average blood glucose
over the prior 120 days and is the gold standard for monitoring diabetic
control.
6. The type of syncope evaluated by tilt table testing that shows
only a decrease in blood pressure without a decrease in heart
rate is called:
1. vasovagal syncope
2. dysautonomic syncope
3. cardiac syncope
4. situational syncope
Answer: 2. In tilt table testing, if only blood pressure decreases without a
decrease in heart rate, it is considered dysautonomic syncope (an
autonomic nervous system disorder). Vasovagal syncope shows decrease
in both BP and heart rate.
7. The term for the process by which cells acquire the ability to
detach from the primary tumor, enter blood or lymphatic vessels,
and establish growth at distant sites is:
1. angiogenesis
2. metastasis
3. invasion
4. seeding
Answer: 2. Metastasis is the ability of cancer cells to spread from the
primary site to distant organs via hematologic or lymphatic spread. It
, involves detachment, intravasation, circulation, extravasation, and growth
at new sites.
8. The test that measures the protein produced by the immune
system that can be elevated in acute or chronic infection,
inflammation, or myeloma, calculated by subtracting albumin
from total protein, is:
1. globulin
2. immunoglobulin
3. C-reactive protein
4. fibrinogen
Answer: 1. Globulin is comprised of immune proteins such as
immunoglobulins (antibodies). Rather than being directly measured,
globulin level is calculated by subtracting albumin from total protein. High
levels can indicate infection, inflammation, or myeloma.
9. The term for a driver's license suspension applied for non-
moving violations, including failure to document insurance
coverage, failure to appear for a court hearing, or failure to pay
child support, is:
1. administrative suspension
2. non-moving violation suspension
3. civil suspension
4. discretionary suspension
Answer: 2. A license suspension can be applied for non-moving
violations, including failure to document insurance coverage, failure to
appear for a court hearing, or failure to pay child support. This differs from
suspensions for moving violations which are more serious.
10. The statistical term for the J-shaped curve seen when plotting
mortality rates against total cholesterol values, showing higher
mortality at both low and high extremes, is:
