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 yea rs ago. Her carcinoembryonic antigen(CEA) level is now 4.2 mcg/L. Is t his 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?S - The Marketplace to Buy and Sell your Study Material Downloaded by: Sophiie | Distribution of this document is illegal S - The Marketplace to Buy and Sell your Study MaterialMosby's Canadian Manual of Diagnostic and Laboratory Tests 2nd Edition Pagana Test Bank Pagana: Mosby’s Canadian Manual of Diagnostic and Laboratory Tests, 2nd Canadian Edition 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. Reference page: 1140 2. Question: A 48-year-old patient is concerned about the radiation exposure risk associated with mammography. She would like to undergo breast scintigraphy inst ead. 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. Reference page: 1088 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
