1A nurse is educating a patient about lifestyle modifications to reduce cancer risk. Which modifiable risk factor has the strongest evidence for cancer prevention?
A.Increasing daily calcium intake
B.Tobacco cessation
C.Drinking green tea daily
D.Taking daily multivitamins
Explanation: Tobacco use is the leading preventable cause of cancer and cancer deaths. Tobacco cessation has the strongest evidence base for reducing cancer risk, as smoking is linked to at least 12 types of cancer. While other lifestyle factors like diet and exercise are important, tobacco cessation provides the single greatest impact on cancer prevention.
2Which screening recommendation is appropriate for average-risk adults according to current guidelines?
A.Colonoscopy every 5 years beginning at age 40
B.Annual mammography beginning at age 45 for women
C.Annual chest X-ray for lung cancer screening in all adults over 50
D.Annual CA-125 testing for ovarian cancer beginning at age 35
Explanation: Current breast cancer screening guidelines recommend annual or biennial mammography beginning at age 40-45 for average-risk women. Colonoscopy is recommended every 10 years (not 5) beginning at age 45. Chest X-ray is not recommended for lung cancer screening; low-dose CT is recommended for high-risk individuals. CA-125 testing is not recommended for ovarian cancer screening in average-risk women.
3A patient with a family history of Lynch syndrome asks about cancer prevention. Which recommendation is most appropriate for this hereditary cancer syndrome?
A.Annual colonoscopy beginning at age 20-25
B.Prophylactic colectomy at age 18
C.Annual fecal occult blood testing beginning at age 50
D.Sigmoidoscopy every 5 years beginning at age 40
Explanation: Lynch syndrome (hereditary non-polyposis colorectal cancer) carries a significantly increased risk of colorectal cancer. Guidelines recommend annual colonoscopy beginning at age 20-25 (or 2-5 years earlier than the youngest case in the family). Standard screening beginning at age 50 is insufficient for this high-risk population.
4A cancer survivor expresses concern about developing a second primary cancer. Which nursing response demonstrates understanding of survivorship care?
A.The risk of second cancers is so low you should not worry about it
B.We will focus on your current treatment and address that later
C.Survivorship care includes surveillance for recurrence and screening for new primaries based on your treatment history
D.Second cancers only occur in patients with genetic mutations
Explanation: Cancer survivors have an increased risk of second primary cancers due to shared risk factors, genetic predisposition, and treatment-related effects (such as radiation and certain chemotherapies). Comprehensive survivorship care includes surveillance for recurrence, monitoring for late effects, and appropriate screening for new primary cancers based on individual risk factors and treatment history.
5Which intervention is most appropriate for a terminally ill patient experiencing existential distress?
A.Increasing the dose of morphine
B.Consulting the palliative care team for psychosocial support and life review
C.Recommending inpatient psychiatric admission
D.Suggesting the patient focus only on physical comfort
Explanation: Existential distress involves concerns about meaning, purpose, and legacy near the end of life. The palliative care team provides comprehensive support including psychosocial interventions, spiritual care, and life review therapy. While physical comfort is important, existential suffering requires specialized psychosocial and spiritual interventions rather than just increased analgesia.
6A patient in hospice care develops terminal restlessness. What is the priority nursing intervention?
A.Administer scheduled haloperidol for agitation
B.Reposition the patient and ensure a calm, quiet environment
C.Initiate intravenous fluids for hydration
D.Transfer the patient to the intensive care unit
Explanation: Terminal restlessness (terminal agitation) requires a comprehensive assessment to identify reversible causes such as pain, urinary retention, or hypoxia. Non-pharmacologic interventions including environmental modifications, family presence, and repositioning are first-line. Medications may be needed but non-pharmacologic measures should be initiated first.
7Which statement best describes the role of a nurse navigator in cancer care?
A.Performing all chemotherapy administration for patients
B.Coordinating care across the continuum and removing barriers to treatment
C.Serving as the primary oncologist for newly diagnosed patients
D.Managing the financial operations of the oncology clinic
Explanation: Nurse navigators play a crucial role in care coordination, helping patients traverse the complex healthcare system. They provide education, coordinate appointments, facilitate communication among care team members, and help remove barriers to care such as transportation or financial concerns. They do not replace physicians or perform all treatments.
8A patient asks about the difference between benign and malignant tumors. Which response is most accurate?
A.Benign tumors are always small and malignant tumors are always large
B.Benign tumors lack the ability to invade surrounding tissues and metastasize
C.Benign tumors grow rapidly while malignant tumors grow slowly
D.Benign tumors are always painful and malignant tumors are painless
Explanation: The key distinguishing feature of malignant tumors is their ability to invade surrounding tissues and metastasize to distant sites. Benign tumors are typically well-circumscribed and do not metastasize. Neither size, growth rate, nor pain are reliable distinguishing characteristics between benign and malignant tumors.
9Which cellular process is primarily responsible for the development of drug resistance in cancer chemotherapy?
A.Apoptosis
B.Mutation of target genes and overexpression of drug efflux pumps
C.Cellular senescence
D.DNA methylation only
Explanation: Cancer drug resistance develops through multiple mechanisms including mutations in target genes, overexpression of drug efflux pumps (such as P-glycoprotein), activation of alternative survival pathways, and enhanced DNA repair mechanisms. These cellular adaptations allow cancer cells to survive despite chemotherapy exposure.
10A patient with colon cancer is staged as T3N1M0. What does this staging indicate?
A.Tumor invades through the muscularis propria, 1-3 regional lymph nodes involved, no distant metastasis
B.Tumor is confined to mucosa, no lymph node involvement, distant metastasis present
C.Tumor invades adjacent structures, more than 6 lymph nodes involved, no distant metastasis
D.Carcinoma in situ, micrometastases to lymph nodes, distant metastasis present
Explanation: In TNM staging, T3 indicates tumor invasion through the muscularis propria into pericolorectal tissues. N1 indicates metastasis in 1-3 regional lymph nodes. M0 indicates no distant metastasis. This would be Stage III colon cancer. Understanding TNM staging is essential for treatment planning and prognosis.
