SECTION 1: CELLULAR REGULATION & CANCER BIOLOGY
Questions 1-20
Question 1
A patient with a history of smoking presents with a persistent cough, weight loss, and hemoptysis. A lung
biopsy reveals malignant cells. Which cellular characteristic is most consistent with malignancy?
A) Increased apoptosis rate
B) Contact inhibition
C) Loss of differentiation (anaplasia)
D) Decreased mitotic rate
Correct Answer: C
Rationale: Anaplasia refers to loss of cellular differentiation, a hallmark of malignant cells. Malignant cells
exhibit high mitotic rates (not decreased), loss of contact inhibition (not maintained), and reduced apoptosis
(not increased). These features allow uncontrolled growth and invasion .
Question 2
A woman with a BRCA1 gene mutation asks about her risk for breast cancer. What is the nurse's best
response?
A) "BRCA1 mutation is not associated with breast cancer risk."
B) "Women with BRCA1 mutations have a 50-80% lifetime risk of breast cancer."
C) "BRCA1 mutations only increase ovarian cancer risk, not breast cancer."
D) "BRCA1 mutations guarantee that you will develop breast cancer."
Correct Answer: B

VERIFIED Q&A | PROCTORED TEST BANK | DETAILED RATIONALES - GRADED A+
Rationale: BRCA1 and BRCA2 are tumor suppressor genes. Mutations significantly increase breast cancer risk
(50-80% lifetime) and ovarian cancer risk (20-40%). The mutations do not guarantee cancer development, as
other factors influence penetrance .
Question 3
During carcinogenesis, the process by which a normal cell acquires genetic mutations leading to malignant
transformation is called:
A) Apoptosis
B) Metastasis
C) Initiation-promotion-progression
D) Angiogenesis
Correct Answer: C
Rationale: Carcinogenesis involves three stages: initiation (DNA damage by carcinogen), promotion
(proliferation of initiated cells), and progression (acquisition of invasive/metastatic capabilities). Apoptosis is
programmed cell death; metastasis is spread to distant sites; angiogenesis is new blood vessel formation .
Question 4
A patient receiving chemotherapy develops neutropenia. Which assessment finding is most concerning?
A) Temperature of 38.3°C (101.0°F)
B) Fatigue
C) Nausea
D) Alopecia
Correct Answer: A

VERIFIED Q&A | PROCTORED TEST BANK | DETAILED RATIONALES - GRADED A+
Rationale: Fever in a neutropenic patient (febrile neutropenia) is a medical emergency indicating possible
sepsis. Neutropenic patients have impaired inflammatory response and may not show typical signs of
infection. Fever is the earliest sign requiring immediate evaluation and antibiotics .
Question 5
A patient with metastatic lung cancer is prescribed bevacizumab (Avastin). Which adverse effect requires
immediate intervention?
A) Hypertension
B) Diarrhea
C) Hemorrhage
D) Fatigue
Correct Answer: C
Rationale: Bevacizumab is an anti-VEGF monoclonal antibody that increases bleeding risk (hemorrhage),
including gastrointestinal bleeding, hemoptysis, and intracranial hemorrhage. Hypertension is also a side
effect but does not require immediate intervention unless severe. Hemorrhage is life-threatening .
Question 6
A patient receiving trastuzumab (Herceptin) for HER2-positive breast cancer should be monitored for which
adverse effect?
A) Cardiotoxicity
B) Nephrotoxicity
C) Ototoxicity
D) Hepatotoxicity

VERIFIED Q&A | PROCTORED TEST BANK | DETAILED RATIONALES - GRADED A+
Rationale: Trastuzumab is a monoclonal antibody against HER2 that can cause cardiotoxicity
(cardiomyopathy, heart failure), especially when combined with anthracyclines (doxorubicin). Baseline and
serial cardiac function monitoring (echocardiography, MUGA) is required .
Question 7
A patient with metastatic lung cancer reports severe bone pain. The nurse understands this is likely due to:
A) Tumor compression of spinal cord
B) Osteolytic metastases
C) Neuropathic pain from chemotherapy
D) Muscle strain from coughing
Correct Answer: B
Rationale: Bone metastases (osteolytic, from lung, breast, kidney, thyroid cancers, or osteoblastic from
prostate cancer) cause bone destruction, release of cytokines, and severe pain. Osteolytic lesions weaken bone,
increasing fracture risk .
Question 8
A patient is receiving tamoxifen for hormone receptor-positive breast cancer. The mechanism of action of
tamoxifen is:
A) Aromatase inhibition
B) Selective estrogen receptor modulation (SERM)
C) Estrogen receptor downregulation
D) Ovarian suppression
Correct Answer: B
