Question 1
Which cellular characteristic is most directly associated with malignant transformation?
A. Controlled cellular differentiation
B. Unregulated cellular proliferation
C. Normal apoptosis
D. Limited replicative capacity
CORRECT ANSWER: B. Unregulated cellular proliferation
RATIONALE: Cancer develops when genetic and epigenetic abnormalities disrupt normal
mechanisms controlling proliferation, differentiation, DNA repair, and apoptosis.
Question 2
Which tumor-suppressor gene is commonly described as the "guardian of the genome"?
A. HER2
B. KRAS
C. TP53
D. BCR-ABL
CORRECT ANSWER: C. TP53
RATIONALE: TP53 encodes p53, a tumor-suppressor protein that responds to cellular stress and
DNA damage by promoting cell-cycle arrest, DNA repair, senescence, or apoptosis.
Question 3
What is the primary purpose of cancer staging?
,A. Determine the patient's blood type
B. Estimate disease extent and help guide treatment and prognosis
C. Determine whether chemotherapy will cause nausea
D. Identify the patient's pain tolerance
CORRECT ANSWER: B. Estimate disease extent and help guide treatment and prognosis
RATIONALE: Staging describes the extent of cancer and is important for prognosis, treatment
selection, and communication about disease status.
Question 4
In the TNM staging system, the N component describes:
A. Primary tumor size
B. Regional lymph-node involvement
C. Distant metastasis
D. Tumor grade
CORRECT ANSWER: B. Regional lymph-node involvement
RATIONALE: T describes the primary tumor, N describes regional lymph-node involvement, and
M describes distant metastasis.
Question 5
Which finding is most concerning for superior vena cava syndrome?
A. Bilateral facial and upper-extremity swelling with venous distention
B. Isolated ankle edema after standing
C. Mild constipation
D. Unilateral knee pain
CORRECT ANSWER: A. Bilateral facial and upper-extremity swelling with venous distention
RATIONALE: Superior vena cava obstruction can cause impaired venous drainage from the head,
neck, and upper extremities, producing facial/upper-body edema and venous distention.
Question 6
, A patient receiving chemotherapy develops a temperature of 38.5°C (101.3°F) and an absolute
neutrophil count of 400/mm³. What is the priority?
A. Reassure the patient that fever is expected
B. Urgently evaluate for febrile neutropenia and infection
C. Encourage strenuous exercise
D. Delay evaluation until the next chemotherapy cycle
CORRECT ANSWER: B. Urgently evaluate for febrile neutropenia and infection
RATIONALE: Fever in a profoundly neutropenic patient is an oncologic emergency because
infection can progress rapidly with few localizing signs.
Question 7
Which laboratory value is most useful for assessing neutropenia severity?
A. Absolute neutrophil count
B. Serum sodium
C. Hemoglobin A1c
D. Serum albumin alone
CORRECT ANSWER: A. Absolute neutrophil count
RATIONALE: ANC quantifies the number of circulating neutrophils and is used to assess infection
risk in patients receiving cancer therapy.
Question 8
Which medication class is commonly used to prevent chemotherapy-induced nausea and
vomiting?
A. 5-HT₃ receptor antagonists
B. Beta blockers
C. Anticoagulants
D. Bisphosphonates
CORRECT ANSWER: A. 5-HT₃ receptor antagonists
RATIONALE: Agents such as ondansetron block serotonin 5-HT₃ receptors and are commonly
incorporated into antiemetic regimens.
