Chapters 1-15 | 100 Questions with Answers
Instructions: This exam contains 100 questions in three formats:
Questions 1-45: Straight Answer (select the best option)
Questions 46-75: "All-Correct-Except" (identify the one false
statement)

The correct answer is provided directly below each question.
PART I: STRAIGHT ANSWER QUESTIONS (1-45)
1. The imaging technique that uses a radioactive substance
formulated to be absorbed by targeted tissues, with images
displayed as planar images or thin slices, is:
1. computed tomography
2. magnetic resonance imaging
3. nuclear medicine scintigraphy
4. digital radiography
Answer: 3. Nuclear medicine uses small amounts of radioactive
substances (radioisotopes) that are absorbed by targeted tissues. A
gamma camera records the distribution, displayed as planar images (3D
data in 2D) or thin slices like CT.
,2. The procedure that involves inserting a needle into the liver
through the skin to obtain a tissue sample for pathology is called:
1. percutaneous transhepatic cholangiography
2. liver biopsy
3. hepatic angiography
4. endoscopic retrograde cholangiopancreatography
Answer: 2. Liver biopsy is done to obtain a sampling of liver tissue for
pathology. It is usually performed after using local anesthesia by inserting
a needle attached to a syringe directly into the liver.
3. The test that measures the electrical response to stimulation of
specific sensory pathways, used to diagnose multiple sclerosis, is:
1. electromyography
2. nerve conduction study
3. evoked potentials
4. electroencephalography
Answer: 3. Evoked potentials are the measured electrical response of the
brain to stimulation of specific sensory pathways. Visual evoked potentials
(VEPs) detect slowing of electrical conduction due to demyelination in
multiple sclerosis.
4. The term for the process by which red and white blood cells
consume glucose when centrifugation is delayed is:
1. hemolysis
2. lipemia
3. glycolysis
4. proteolysis
Answer: 3. If centrifugation is delayed too long, the red and white blood
cells will consume (metabolize) the glucose. This loss of glucose is called
glycolysis. It causes falsely low glucose results.
,5. The condition in which an individual has an A1c level of 5.7-
6.4% is classified as:
1. diabetes mellitus
2. pre-diabetes
3. normal
4. impaired fasting glucose only
Answer: 2. An A1c level of 5.7-6.4% represents pre-diabetes. Normal is
below 5.7%, and diabetes is 6.5% or greater on two separate occasions.
6. The type of hypotension that can result from disorders of the
autonomic nervous system such as Parkinson's disease or
diabetic neuropathy is:
1. vasovagal syncope
2. orthostatic hypotension
3. postprandial hypotension
4. neurocardiogenic syncope
Answer: 2. Chronic postural hypotension can result from disorders of the
autonomic nervous system such as Parkinson's disease, diabetic or
alcoholic neuropathy, multiple sclerosis, and chronic renal or liver
diseases.
7. The term for the process by which cells undergo programmed
cell death in an orderly manner for the benefit of the entire organ
system is:
1. necrosis
2. apoptosis
3. autophagy
4. pyroptosis
Answer: 2. Apoptosis is a type of programmed cell death that occurs in
an orderly manner for the benefit of the entire organ system. It is tightly
regulated to ensure the integrity of all organs and tissues.
, 8. The test that measures a low molecular weight protein present
in all nucleated cells, freely filtered by the glomerulus, and used
as an alternative to creatinine for renal function is:
1. BUN
2. cystatin C
3. beta-2 microglobulin
4. retinol-binding protein
Answer: 2. Cystatin C is a low molecular weight protein present in all
nucleated cells. It is freely filtered by the glomerulus and destroyed in the
kidney's tubules. It varies little by sex, diet, or body mass.
9. The term for a driver under age 21 who is subject to license
suspension for any measurable amount of alcohol in their blood
is:
1. administrative per se
2. implied consent
3. zero tolerance law
4. minor in possession
Answer: 3. Zero tolerance law makes it illegal per se for persons under
age 21 to drive with any measurable amount of alcohol in their blood.
Most jurisdictions have established lower BAC levels (0.01% or 0.02%) for
youthful drivers.
10. The statistical term for the measure of how well a laboratory
test excludes the possibility of a particular disease (identify true
negatives) is:
1. sensitivity
2. specificity
3. predictive value positive
4. predictive value negative
Answer: 2. Specificity is the measure of how well the test excludes the
possibility of a particular disease or abnormal health condition (identify
true negatives). Sensitivity identifies true positives.
