Mild renal insufficiency
Hypertension
History of peptic ulcer disease

Correct answer: Severe pulmonary dysfunction

Bleomycin causes pulmonary fibrosis and is contraindicated in patients with severe pre-existing pulmonary dysfunction because it can cause fatal respiratory compromise.

Question 13: According to the TNM (Tumor, Node, Metastases) staging system in widespread use, which of the following would be expected to have the highest stage and most likely the worst prognosis in a case of gastric cancer?

TINOM1 (Correct answer)
TIN2MO
TINOMO
T2N2MO

Correct answer: TINOM1

Explanation: In the common TNM system for assessing stage. T refers to the size or degree of invasion of the primary tumor. In gastric cancer, T1 would show invasion of the lamina propria or submucosa while T2 would show invasion of the muscularis layer. N refers to nodal involvement with NO, indicating none, and N1 and N2, indicating perigastric nodal involvement with cancer: N1 within 3 cm of the primary tumor and N2 beyond 3 cm or in distant nodes. M refers to distant metastases: MO none, M1 any metastases. Thus, answer A would be stage 1A; B stage 4 because of metastatic disease, C stage Ill, and D stage Il. Interestingly, this cancer is very common in Japan and relatively uncommon in the United States, though the incidence has been rising here recently. Dietary factors likely play a role.

Question 14: A nurse is preparing to administer doxorubicin. Which piece of personal protective equipment (PPE) is MOST essential according to NIOSH hazardous drug handling guidelines?

Single nitrile gloves
Surgical mask only
Standard latex gloves and paper gown
Double chemotherapy-rated gloves and a closed-front gown (Correct answer)

The Ann Arbor staging system classifies Hodgkin and non-Hodgkin lymphoma by the number and location of lymph node regions involved and presence of extranodal disease.

Question 17: A patient on vincristine reports difficulty walking and tingling in the hands and feet. The nurse should recognize this as:

Bone marrow suppression
Peripheral neuropathy, a dose-limiting toxicity of vincristine (Correct answer)
A sign of extravasation at the infusion site
Hypercalcemia related to the malignancy

Correct answer: Peripheral neuropathy, a dose-limiting toxicity of vincristine

Vincristine causes peripheral neuropathy as its primary dose-limiting toxicity due to its mechanism of inhibiting microtubule formation in nerve cells.

Question 19: A patient with ovarian cancer suddenly develops severe nausea. She is vomiting large volumes of fluid. Her abdomen is painful and rigid on palpation, and bowel sounds are diminished. She reports feeling short of breath. She is afebrile. She reports that she has had only very small bowel movements recently. The most likely diagnosis is:

Peritonitis
Obstruction of colon
Fecal impaction
Obstruction of small intestines (Correct answer)

Correct answer: Obstruction of small intestines

Explanation: These symptoms are consistent with an obstruction of the small intestines. Sudden and frequent nausea and vomiting in large volumes that occurs immediately after intake usually indicates a small bowel obstruction. An obstruction of the colon usually results in more delayed vomiting, with fecal emesis. If obstruction is partial or inoperable, dexamethasone may relieve some of the symptoms because it reduces inflammation and swelling, as well as providing relief of nausea.

Question 20: Which approach is most effective for mastering oncologic emergencies in Oncology Nursing Certification Corporation?

Question 23: Which of the following may be an indication of non-medical opioid use in a cancer patient being treated for pain?

The patient asks about changing drugs to improve analgesia.
The patient keeps a pain diary.
The patient maintains meticulous records of pain medications.
The patient repeatedly loses pain medication. (Correct answer)

Correct answer: The patient repeatedly loses pain medication.

Explanation: Although most guidelines exempt cancer patients from limitations on the use of opioids, studies show that about 20% of cancer patients engage in non-medical opioid use, such as by increasing doses, using along with other drugs or alcohol, and sharing with other people. Signs of non-medical opioid use include repeatedly losing or misplacing medications, asking for early refills, increasing the dosage without discussing it with healthcare providers, refusing to change medication, and asking for opioids for non-pain issues such as insomnia.

Question 24: Which lab value is the MOST important to assess before administering methotrexate at high doses?

Renal function (BUN and creatinine) (Correct answer)
Liver enzymes only
Serum glucose
Serum potassium

Correct answer: Renal function (BUN and creatinine)

High-dose methotrexate is renally excreted; impaired kidney function causes drug accumulation leading to severe mucositis, myelosuppression, and organ toxicity.

A practice used only by large organizations
A method or technique recognized as superior based on evidence and expert consensus (Correct answer)

Instruct the patient to keep the area dry and avoid all topical products

Correct answer: Cleanse the area gently with mild soap and water and apply a moisture barrier

Gentle cleansing with mild soap and water followed by a moisture barrier is recommended for grade 2 radiation dermatitis to maintain skin integrity.

Question 29: A patient with multiple myeloma is receiving a bisphosphonate (zoledronic acid). Which adverse effect requires regular dental evaluation before and during therapy?

Renal tubular acidosis
Osteonecrosis of the jaw (ONJ) (Correct answer)
Cardiotoxicity and arrhythmias
Peripheral neuropathy

Correct answer: Osteonecrosis of the jaw (ONJ)

Bisphosphonate therapy, especially intravenous agents, significantly increases the risk of osteonecrosis of the jaw, making pre-treatment dental evaluation and ongoing oral hygiene critical.

Question 30: Which of the following cancer types has decreased the most in incidence during the previous decade?

Prostate (Correct answer)
Female breast
Melanoma
Lung

Correct answer: Prostate

Explanation: Overall cancer incidence has declined somewhat in men (1.5%) and has stabilized for women. Prostate cancer has declined the most in recent years; there are about 3% fewer cases per year. The incidence of liver cancer has increased the most, approximately 3.9% per year. Other cancers with reduced rates include Hodgkin lymphoma and leukemia, male lung cancer, and stomach and uterine cancers. Melanomas, kidney, and thyroid have also shown a slightly increased incidence. Do not confuse incidence with survival rates. Cancer survival rates are usually expressed as five-year survival and include persons with disease still getting treatment and those who are alive at 5 years after diagnosis with no evidence of disease (NED). Improvements in the survival rate may reflect better treatments or perhaps earlier diagnosis.
