At a prevention visit, a 62-year-old man reports smoking 30 cigarettes daily for 12 years, then 10 daily for 16 years, followed by 8 years without smoking. He has no lung-cancer symptoms, is medically fit for lung surgery, and would accept curative treatment. Under the USPSTF's 2021 lung cancer screening recommendation, which assessment is accurate?
Correct answer: D - 26 pack-years; offer annual low-dose CT after discussing its benefits and potential harms.
During a follow-up call, a man with metastatic prostate cancer mentions new lower-back pain. He can still walk, but since this morning his legs have felt weak and he has had difficulty starting urination. He has an oncology appointment tomorrow. What instruction should the navigator give now?
Correct answer: C - Obtain emergency evaluation now for possible spinal cord or cauda equina compression.
The morning after her first oxaliplatin infusion, a patient reports brief tingling around her mouth when drinking iced water and in her fingers when removing food from the freezer. Both episodes resolved with warming. She has no rash, swelling, breathing or swallowing difficulty, weakness, or persistent numbness. Which teaching point fits this pattern?
Correct answer: B - Avoid cold drinks and objects, and report symptoms that persist or interfere with daily activities.
A clinical trial requires ECOG performance status 0-2. A patient being considered for referral walks independently, performs all personal care, and is up and about for roughly three quarters of her waking day. Fatigue prevents even light household or desk work. No other eligibility criteria have been reviewed. Which entry accurately communicates her status to the research team?
Correct answer: A - ECOG 2; she meets the performance-status requirement, with the remaining eligibility review still needed.
Before her mother's first oncology visit, a daughter asks the team not to use the word "cancer," explaining that this would destroy her mother's hope. Her mother makes her own healthcare decisions, and a qualified interpreter will attend. Her preferences about receiving information have not been discussed. How should the navigator begin resolving this request?
Correct answer: A - Privately ask the mother how she prefers to receive medical information and involve her daughter.
A 77-year-old patient starting an oral anticancer drug lives alone and manages bathing, dressing, and meals independently. His daughter says he will manage treatment because he "understands everything." The actual prescription is one tablet each morning on days 1-14, followed by no tablets on days 15-21. He can read the label but says the treatment-free week is confusing. What would provide the strongest evidence that the teaching worked?
Correct answer: C - He accurately marks dose and treatment-free days on his calendar, then explains the schedule.
A patient receiving radiation rates distress at 7 out of 10 on the NCCN Distress Thermometer. In the follow-up conversation, she identifies unpaid rent and unreliable transportation as her main concerns. She remains engaged in treatment, denies thoughts of self-harm, and describes no persistent loss of interest or hopelessness. Which plan best connects the screening result to her assessed needs?
Correct answer: B - Connect her with oncology social work for rent and transportation support, then reassess distress.
A 29-year-old survivor of Hodgkin lymphoma treated at age 14 is transferring to adult follow-up care. He feels well. The records confirm prior doxorubicin and chest radiation but contain no exposure details. For planning treatment-related cardiac surveillance, which information should the navigator obtain first?
Correct answer: D - His cumulative doxorubicin dose and the radiation fields and doses documented in the treatment record.
"I want to keep treating the cancer, but I need enough energy and pain control to attend my son's graduation," says a patient whose metastatic disease is responding to therapy. Her oncologist supports continuing treatment. She worries that accepting palliative care would mean giving it up. Which explanation addresses that concern?
Correct answer: B - Palliative care can address symptoms and personal goals while cancer-directed treatment continues.
A program tracks diagnostic colonoscopy within 60 days after a positive screening FIT. Its measure includes every patient with a positive FIT, with no exclusions. All 80 patients in the audit have reached day 60: 52 completed colonoscopy, 12 have a later appointment, 8 declined, and 8 could not be reached. The local target is 75%. What belongs in the report to the cancer committee?
Correct answer: A - 65%; the target was missed, so examine barriers among patients without completed colonoscopy.
