Question 1

Sensory evoked potential (SEP)is useful in diagnosing which type of abnormality?
A)Hepatic tumor
B)Kidney stones
C)Acoustic neuroma

A)MRI
B)PET
C)Ultrasound
D)Fluoroscopy

Accepted Answer

Positron emission tomography (PET)is a form of nuclear imaging that combines elements of CT scanning and nuclear scanning to create a picture that represents the brain or other organs.The radioisotopes used emit positrons that cause pairs of gamma rays to be discharged and converted into images.

C)T₂ N₁ M₀
D)T₁ N₁ M₁

Question 5

What type of cancer treatment involves the partial removal of the tumor?
A)Endocrine therapy
B)Surgical palliation
C)Surgical debulking
D)Ablation of tumor

In surgical debulking,the tumor is partially removed; this treatment is preferred for some incurable malignant neoplasms.

Question 6

What type of specimen is collected with a circular sharp,hollow tip?
A)Aspiration biopsy
B)Brush biopsy
C)Punch biopsy
D)Smear

Accepted Answer

A punch biopsy is an instrument with a 3- to 4-mm circular sharp,hollow tip used to sample skin lesions in a cookie-cutter manner.

Question 7

What type of tumor grows slowly and resembles the parent tissue of origin?
A)Percutaneous
B)Benign
C)Malignant
D)Prophylactic

Accepted Answer

A benign tumor is an aggregation of cells that closely resemble those of the parent tissue of origin; it grows slowly by expansion,is localized,and surrounded by a capsule of fibrous tissue.

Question 8

What may pose a possible risk of allergic reaction to contrast media used during a radiologic procedure?
A)Allergy to feline hair
B)Iodine sensitivity
C)Rash caused by surgical tape
D)Allergy to polypropylene suture

Accepted Answer

When assessing a patient,if a history of sensitivity to substances that contain iodine,shellfish,or Betadine is present,then a test dose may be given before the procedure.True shellfish allergies are not related to iodine.

Question 9

What type of cancer cells are contained within the organ of origin?
A)Regional cancer
B)Carcinoma in situ
C)Metastatic cancer
D)Localized cancer

Accepted Answer

Localized cancer is contained within the organ of origin and does not extend by way of lymphatic or vascular channels.

Question 10

According to the American Cancer Society,which is a common clinical sign of cancer?
A)Palpable mass
B)Abnormal bleeding or discharge
C)Nonhealing lesion
D)All of the above

Accepted Answer

There can be many warning signs of cancer: abnormal bleeding,a palpable mass,decrease in weight or appetite,fatigue,and a change in bowel habits are just a few.Any unsuspected change in a patient's body is an indication to have a checkup.

Question 11

Which commonly used contrast medium is given to patients to drink before GI studies.
A)Omnipaque
B)Barium sulfate
C)Iodine/Betadine
D)Magnesium sulfate

Accepted Answer

Barium sulfate can either be swallowed or instilled by enema to outline the lumina of segments of the tract to be studied.

Question 12

What group of people should receive a mammogram?
A)Women more than 50 years old
B)Women between the ages of 20 and 35
C)Men with a familial history of maternal breast cancer
D)Mammograms are not recommended for any age group

Accepted Answer

After the age of 50 years,every woman should have a yearly mammogram.Mammography is not contraindicated in women with breast implants.Men with suspicious breast lesions or pronounced gynecomastia should have a mammogram.

Question 13

____________ may contribute to the formation of cancerous tumors.
A)Holistic medical care
B)Radiation
C)Endoscopy
D)Excessive protein intake

Accepted Answer

Some cancerous tumors can be caused by exposure to chemical toxins,ionizing radiation,chronic tissue irritation,tobacco smoke,UV rays,viral invasion,and genetic predisposition.

Question 14

What type of radiologic study can accompany a cholecystectomy?
A)Bronchography
B)Cholangiography
C)Myelography
D)Fluoroscopy

Accepted Answer

A cholangiography assists in the identification of gallstones in the biliary tract and requires contrast medium to be injected either intravenously or directly into the bile ducts.

Question 15

What is one key factor to consider when attempting to minimize radiation exposure?
A)Position
B)Time
C)Square footage
D)Sensitivity

Accepted Answer

Time,distance,and shielding are key factors in minimizing radiation exposure.Personnel should stand at least 6 feet away from the x-ray and wear lead aprons or at least wear gonadal and sternal protection.Patients should also wear gonadal protection.

Question 16

A malignant tumor
A)migrates from tissue to tissue.
B)grows in an organized manner.
C)increases in size slowly.
D)must always be debulked.

Accepted Answer

Cancer cells grow in a disorganized and uncontrolled manner.They increase in size rapidly.

Question 17

What type of culture requires immediate attention?
A)Smears
B)Biopsy
C)Aerobic
D)Anaerobic

Accepted Answer

Anaerobic cultures require immediate attention because exposure to room air may kill the anaerobes in a few minutes.

Question 18

Why would an incidental radiograph be taken during a surgical procedure?
A)To check suture lines
B)To look for bleeding
C)To confirm whether an instrument is still in the patient
D)To ensure the bowel anastomosis has a watertight seal

Accepted Answer

An incidental radiographic film would be taken if a sponge,needle,or instrument is unaccounted for at the end a procedure and is believed to be in the patient.

Question 19

What type of procedure does not enter the patient's body and uses equipment placed near the patient's skin?
A)Invasive
B)Interventional
C)Noninvasive
D)Percutaneous

Accepted Answer

Noninvasive techniques use equipment placed on or near the patient's skin but outside the body tissues.

What type of radiologic procedure is used to study a joint after the injection of gas or contrast into it?
A)Ventriculography
B)Computed tomography
C)Arthrography
D)Ultrasonography

Accepted Answer

Arthrography is the study of a joint after the injection of gas or contrast medium into it.Injury to cartilage or ligaments can be visualized.
