Review Questions
Cancer
1. Question: A 36-year-old patient indicates that she wants both of her breasts removed
because of a strong family history of breast cancer. Her mother developed breast
cancer at age 45 and died of that disease at age 50. Her older sister is now dying of
breast cancer at age 44. The patient has two young daughters and does not want to
risk dying before her children grow up. What advice should the nurse give her?
2. Question: A 48-year-old patient is concerned about the radiation exposure risk
associated with mammography. She would like to undergo breast scintigraphy
instead. What advice should the nurse give her?
3. Question: During a routine evaluation, a patient is found to have a suspect lesion on
mammography. Her physical examination results are negative, and she has no
palpable masses. Should a biopsy of this mass be performed?
4. Question: The patient is a 56-year-old woman who had a colon cancer removed 2
years ago. Her carcinoembryonic antigen(CEA) level is now 4.2 mcg/L. Is this
significant?
5. Question: A 62-year-old patient is admitted to the hospital for melanoma. During his
staging workup, a bone scan is performed. The bone scan is normal except for a “hot
spot” in the right rib. What might have caused this abnormality?
6. Question: A 22-year-old female patient complains of right upper quadrant abdominal
pain. Gallbladder ultrasonography and upper gastrointestinal endoscopy are
performed, and the results are negative. A liver-spleen scan indicates a filling defect
in the anterior surface of the liver. Does this indicate a liver tumour?
7. Question: A patient with a diagnosis of pancreatic cancer has recently been admitted
to the hospital with a rapid onset of ascites. She is extremely uncomfortable and
anxious to institute treatment for this symptom. The nurse is aware that the CA 19-9
tumour marker tests have been performed. What is the purpose of the CA 19-9
marker and how could it influence care?

Review Questions Answer Key
Cancer
1. Question: A 36-year-old patient indicates that she wants both of her breasts removed
because of a strong family history of breast cancer. Her mother developed breast
cancer at age 45 and died of that disease at age 50. Her older sister is now dying of
breast cancer at age 44. The patient has two young daughters and does not want to
risk dying before her children grow up. What advice should the nurse give her?
Answer: This woman does have a significant family history of breast cancer and may
have a breast cancer antigen (BRCA) genetic defect. If appropriate, the nurse should
provide information on how the patient and her sister could be tested for the BRCA
gene. If the test is positive, further genetic consultation is required. It is important to
inform the BRCA-negative patient that her risk is still similar to that of the general
public.

2. Question: A 48-year-old patient is concerned about the radiation exposure risk
associated with mammography. She would like to undergo breast scintigraphy
instead. What advice should the nurse give her?
Answer: Mammography is an X-ray examination of the breast that is performed with
exposure to approximately 0.5 rad of radiation per view. Scintigraphy involves an
injection of an intravenous radionuclide and the use of a gamma ray scintigraphy
camera to pass over the breasts and record radioactive uptake or “hot” or “cold”
spots. Because the amount of radionuclide used in scintigraphy is small, there is a
relatively low risk of radiation exposure; however, mammography has an even lower
risk of radiation exposure than scintigraphy.

3. Question: During a routine evaluation, a patient is found to have a suspect lesion on
mammography. Her physical examination results are negative, and she has no
palpable masses. Should a biopsy of this mass be performed?
Answer: Mammography can be used to locate a mammographically identified (i.e.,
not palpable) lesion for biopsy, but follow up is required. It is important to inform the
patient that further testing is not uncommon after a mammograph. If the radiologist
sees something that should be more thoroughly evaluated with magnified views,
deeper views, or ultrasonography, the patient may be called back for further testing,
prior to performing a biopsy.
