NR 509 Final Exam - Study guide Questions and Answers Top Graded 2024

1. A 44-year-old female mathematician presents to clinic with a complaint of a mass in the right breast. Her partner noticed this mass 2 days ago, and the patient feels guilty because she has only had one mammogram and does not engage in breast self- examination (BSE) on any regular basis. She has no family history of breast cancer, and her prior mammogram was ordered as a routine screening test at age 43 years after a brief discussion with her primary care provider. After a thorough investigation reveals a benign cyst, what advice should be given to this patient about screening for breast cancer in her age group? Ans: This patient was in compliance with the U.S. Preventive Services Task Force (USPSTF) recommendations for her age group and risk factors prior to her current complaint. 2. A 42-year-old female website developer presents for an annual preventive examination with questions about breast cancer screening. She is concerned about the radiation exposure associated with mammography and is interested in magnetic resonance imaging (MRI) as a possible alternative for routine screening. She is otherwise healthy with no family history of breast, ovarian, or colon cancer. Which of the following is true about MRI as a screening modality for breast cancer in the general population? Ans: Sensitivity of screening for breast cancer increases with breast MRI at the expense of specificity. 3. A 35-year-old G0P0 woman presents to clinic with a complaint of bilateral nipple discharge. This discharge started several weeks ago and has occurred at irregular intervals since that time. She does not complain of local tenderness, redness, fever, or any other systemic symptoms aside from slightly irregular periods over the last few months. On examination, she is able to express a small amount of discharge, which is sent to the laboratory and found to be consistent with breast milk but without any signs of blood or pus. Screening laboratories are also sent, which reveal a normal blood count, metabolic panel, thyroid-stimulating hormone, and human chorionic gonadotropin (HCG) level. Further laboratories are still pending. Which of the following is the most likely diagnosis? Ans: Prolactinoma 4. A 22-year-old G0P0 undergraduate student presents to clinic after finding a breast mass on breast self-examination (BSE) at home. The mass is nontender without skin changes, erythema, or overlying swelling. She has heard that most breast cancers are found by patients themselves, and she is very concerned that she may have breast cancer. Which of the following is true about BSE and self-detection of breast cancer? Ans: This patient is more likely to find a fibroadenoma than a cancer on self-examination. 5. A 48-year-old female psychologist presents to clinic with concerns about her breast cancer risk after an age-matched cousin was recently diagnosed with this disease. This cousin is the third family member on her father’s side in as many years to be diagnosed with breast cancer, including the patient’s own father, who had surgery and subsequent treatment 3 years ago for breast cancer. The patient has little other knowledge of her family history, only that her grandparents independently arrived from Eastern Europe near the end of World War II and were among very few members of their family that survived the war. The patient has read about testing for the breast cancer genes (BRCA1 and BRCA2) and desires further information about whether this would be appropriate for her. Which of the following is true about this patient’s indications for BRCA testing? Ans: This patient carries several risk factors that together justify BRCA testing. 6. A 68-year-old former paleontologist presents to clinic with concerns about her breast cancer risk. Her mother developed the disease in her 50s and died from it in her 60s. A younger cousin developed the disease a few years ago before the age of 50 years, but this individual was not tested for the BRCA1 and BRCA2 genes. In addition, the patient suffered from lymphoma in her 20s and had radiation to the chest. She did take hormone replacement therapy for a few years before data emerged that this may contribute to breast cancer risk. She has had several abnormal mammograms in her 50s for persistently dense breasts with subtle findings, but follow-up biopsies never showed any malignant pathology. Which of the following is true regarding magnetic resonance imaging (MRI) screening of this patient? Ans: Regardless of recommendations, the high sensitivity of breast MRI comes at the expense of markedly decreased specificity (i.e., the ability to rule out disease in healthy breasts). 7. A 66-year-old female museum curator presents for a routine annual examination. On examination, a notably enlarged supraclavicular lymph node is appreciated on the right side. The lymph node is nontender and feels firm and rubbery. She denies any localized or systemic symptoms such as breast lumps, fevers, or night sweats. She has been taking conjugated estrogen tablets for 9 years since menopause, though she has not taken progestin compounds since she had a hysterectomy for heavy bleeding at age 45 years. Which of the following is true about this presentation of lymphadenopathy? Ans: Metastatic breast cancer cells may spread directly into the infraclavicular and then supraclavicular nodes without first causing notable changes in the axillary nodes.
