Oncology Questions
1. A 62-year-old woman diagnosed with breast cancer is scheduled for a partial mastectomy. The oncology nurse explained that the surgeon will want to take tissue samples to ensure the disease has not spread to adjacent axillary lymph nodes. The patient has asked if she will have her lymph nodes dissected, like her mother did several years ago. What alternative to lymph node dissection will this patient most likely undergo?
- A. Lymphadenectomy
- B. Needle biopsy
- C. Open biopsy
- D. Sentinel node biopsy
Correct answer: D
Rationale: Sentinel lymph node biopsy is a minimally invasive alternative to more extensive lymph node dissection. This procedure involves identifying and removing the first lymph node(s) to which a tumor drains, known as the sentinel node(s), to determine if cancer has spread beyond the primary site. Choices A, B, and C are incorrect because lymphadenectomy refers to the surgical removal of lymph nodes, needle biopsy involves sampling tissue with a needle for analysis, and open biopsy refers to the surgical removal of a sample of tissue for examination, none of which specifically serve as an alternative to lymph node dissection in this context.
2. A 37-year-old woman has a 10 pack-year smoking history and has been using oral contraceptives for the past 2 years. The nurse should plan health education interventions knowing that this patient faces an increased risk of
- A. osteoporosis.
- B. dementia.
- C. myocardial infarction.
- D. deep vein thrombosis.
Correct answer: C
Rationale: The correct answer is C: myocardial infarction. Women aged 35 and older who smoke, especially with a history of 10 pack-years like in this case, face an increased risk of cardiovascular disorders, including myocardial infarction, when using oral contraceptives. Choice A, osteoporosis, is incorrect because smoking and oral contraceptives do not significantly increase the risk of osteoporosis. Choice B, dementia, is not directly associated with smoking, oral contraceptives, or their combination. Choice D, deep vein thrombosis, is a risk associated with oral contraceptives, especially in combination with smoking, but the highest increased risk in this case is for myocardial infarction.
3. The nurse is providing anticipatory guidance to the parent of a 9-month-old infant during a well-baby visit. Which topic would be most appropriate?
- A. Cautioning about putting the infant in a walker
- B. Advising how to create a toddler-safe home
- C. Instructing on safety procedures during baths
- D. Warning about leaving small objects on the floor
Correct answer: D
Rationale: The correct answer is D because at 9 months, infants become more mobile, increasing the risk of choking hazards from small objects left on the floor. Cautioning about putting the infant in a walker (Choice A) is not as crucial at this age as warning about choking hazards. While advising how to create a toddler-safe home (Choice B) is essential, the most critical concern at 9 months is small objects. Instructing on safety procedures during baths (Choice C) is important but does not address the immediate risk of choking hazards associated with small objects.
4. The nurse is assessing a client who had a cast placed 4 hours ago. What assessment finding is cause for concern?
- A. The nurse assesses capillary refill of 2 seconds
- B. The nurse cannot insert one finger between the cast and the skin
- C. The nurse finds 2+ pulses distal from the cast
- D. The nurse does not observe any drainage
Correct answer: B
Rationale: Inability to insert a finger between the cast and skin indicates the cast is too tight, risking circulation problems.
5. A teacher in a preschool is diagnosed with giardiasis. Which of the following medications will be administered to treat the diarrhea and abdominal distention?
- A. Sulfasalazine (Azulfidine)
- B. Metronidazole (Flagyl)
- C. Trimethoprim–sulfamethoxazole (Bactrim)
- D. Doxycycline (Vibramycin)
Correct answer: B
Rationale: The correct answer is B. Metronidazole (Flagyl) is the drug of choice for treating giardiasis, which is a common cause of diarrhea and abdominal distention. Sulfasalazine (Choice A) is used to treat inflammatory bowel disease. Trimethoprim–sulfamethoxazole (Choice C) is commonly used for urinary tract infections and Pneumocystis jirovecii pneumonia. Doxycycline (Choice D) is commonly used to treat various bacterial infections but is not the first-line treatment for giardiasis.
