PART I: STRAIGHT ANSWER QUESTIONS (1-45)
1. The imaging modality that uses a magnetic field and radio
waves to produce unparalleled pictures of soft tissue without
ionizing radiation 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. It produces unparalleled
pictures of soft tissue, organs, bone, and other internal structures without
ionizing radiation.
,2. The procedure that involves insertion of a needle into the
pleural space to remove fluid for diagnosis or treatment is called:
1. thoracentesis
2. thoracoscopy
3. mediastinoscopy
4. bronchoscopy
Answer: 1. Thoracentesis is performed when fluid accumulates between
the visceral (lung) and parietal (chest wall) pleura. A needle is inserted
into the pleural space to remove fluid for diagnosis or to treat symptoms.
3. The test that measures the electrical activity of muscle fibers
individually and collectively by inserting a needle electrode into a
muscle is:
1. electromyography
2. nerve conduction study
3. evoked potentials
4. electroencephalography
Answer: 1. Electromyography (EMG) involves insertion of a needle
electrode into a muscle and recording of electrical activity of muscle fibers
individually and collectively. It is used to diagnose neuropathy and
myopathy.
4. The term for the process of separating serum from the clot by
spinning the sample in a centrifuge is:
1. glycolysis
2. hemolysis
3. centrifugation
4. coagulation
Answer: 3. After blood is allowed to clot, the sample is centrifuged to
separate the red and white blood cells from the serum. This process is
called centrifugation.
,5. The condition in which an individual has a fasting blood glucose
of 126 mg/dl or more on two separate occasions is diagnostic of:
1. pre-diabetes
2. type 1 diabetes only
3. diabetes mellitus
4. impaired glucose tolerance
Answer: 3. A fasting blood glucose of 126 mg/dl or more on two separate
occasions is diagnostic of diabetes mellitus. This applies to both type 1
and type 2 diabetes.
6. The type of hypotension defined as a drop in systolic BP of at
least 20 mmHg or diastolic BP of 10 mmHg or more upon standing
from a supine position is:
1. vasovagal syncope
2. orthostatic hypotension
3. neurocardiogenic syncope
4. postprandial hypotension
Answer: 2. Postural or orthostatic hypotension is defined as a drop in
systolic BP of at least 20 mmHg or a drop in diastolic BP of 10 mmHg or
more upon standing from a supine (lying) position.
7. The term for the process by which cancer cells generate their
own blood supply to support growth is called:
1. metastasis
2. angiogenesis
3. apoptosis
4. differentiation
Answer: 2. Angiogenesis (or neovascularization) is the ability of cancer
cells to generate/promote blood vessel growth to supply nutrients and
oxygen to the tumor, supporting continued growth and metastasis.
, 8. The test that measures the protein produced by plasma cells
that can be elevated in multiple myeloma is:
1. albumin
2. total protein
3. globulin
4. prealbumin
Answer: 3. Globulin is comprised of immune proteins such as
immunoglobulins (antibodies). High levels can indicate infection,
inflammation, or myeloma. Monoclonal gammopathy of undetermined
significance (MGUS) can progress to myeloma.
9. The term for a law that provides for an immediate driver's
license suspension for alcohol-impaired drivers, also called "on-
the-spot" suspension, is:
1. implied consent law
2. administrative per se law
3. zero tolerance law
4. ignition interlock law
Answer: 2. Administrative per se is a law that provides for an immediate
driver's license suspension for alcohol-impaired drivers. It is also referred
to as an "on-the-spot" license suspension law.
10. The statistical term for the measure of a test's ability to
detect persons who have a disease (true positives) is:
1. specificity
2. sensitivity
3. reliability
4. accuracy
Answer: 2. Sensitivity is the measure of the test's ability to detect
persons who have a disease or abnormal health condition (identify true
positives). Specificity identifies true negatives.
