Cardiotoxicity and arrhythmias
Peripheral neuropathy
Renal tubular acidosis

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 10: Which of the following would confer the worst prognosis for female breast cancer?

Lobular carcinoma in situ
1.0 cm tumor in left breast
Inflammatory histology (Correct answer)
Estrogen-positive receptors

Correct answer: Inflammatory histology

Explanation: Numerous factors influence the prognosis for female breast cancer, including histology and grade, tumor size, lymph node involvement, hormone-receptor status, tumor proliferative index, and several others. Lobular carcinoma is often an incidental finding that does not show up on mammography and carries an increased risk for invasive breast cancer, approximately 1% per year in either breast. Tumor size is an important marker for prognosis and tumors over 5 cm may increase the stage from II to III and worsen the prognosis. Inflammatory carcinoma of the breast often appears suddenly with skin changes but no discrete nodule and confers a poor prognosis. Tumors associated with estrogen and/or progesterone receptors tend to have a better prognosis than those that are receptor-negative.

Question 15: A patient undergoing radiation therapy for head and neck cancer is at highest risk for which nutritional complication?

Hypercalcemia
Mucositis leading to dysphagia and malnutrition (Correct answer)
Dumping syndrome
Iron deficiency anemia

Correct answer: Mucositis leading to dysphagia and malnutrition

Mucositis and xerostomia from head and neck radiation commonly cause severe dysphagia, placing patients at high risk for malnutrition.

Question 16: Which pattern of cellular growth is characteristic of cancer cells?

Anaplasia (Correct answer)
Metaplasia
Dysplasia
Hyperplasia

Correct answer: Anaplasia

Explanation: Numerous cells undergo growth patterns that in some cases are normal responses to injury or irritation while in others they may be precursors to malignant changes. Hyperplasia, an increase in the number of cells in a tissue, maybe a normal response in wound healing or a premalignant condition but is not a defining characteristic of cancer. Metaplasia is a potentially reversible process that involves the replacement of one type of mature cell with another not usually found it that tissue. Examples are squamous cell replacement of columnar epithelial cells in the airway of smokers or the replacement of typical cells of the distal esophagus with intestinal epithelium in the Barrett esophagus. Dysplasia refers to a loss of uniformity of particular cells with changes of size, shape, and architecture. Malignant cell growth is usually described as anaplastic, which is marked by extreme cellular disorganization, immature forms, and prominent nuclei.

Question 22: A patient who received an allogeneic stem cell transplant develops a diffuse skin rash, severe diarrhea, and elevated bilirubin 3 weeks post-transplant. The nurse recognizes this presentation as:

Chemotherapy-induced mucositis
Veno-occlusive disease of the liver
Acute graft-versus-host disease (GVHD) (Correct answer)
Engraftment syndrome

Correct answer: Acute graft-versus-host disease (GVHD)

Acute GVHD classically presents in the first 100 days post-allogeneic transplant with a triad of skin rash, diarrhea, and hepatic dysfunction (elevated bilirubin) as donor T-cells attack host tissues.

Question 23: Which finding is most consistent with neutropenic fever in a patient with hematologic malignancy receiving chemotherapy?

Temperature of 37.5°C (99.5°F) with an ANC of 2,500/µL
Single oral temperature ≥38.3°C (101°F) or ≥38°C (100.4°F) sustained, with ANC <500/µL (Correct answer)
Temperature of 39°C with normal ANC and positive blood cultures only
Chills without fever with ANC of 1,000/µL

Correct answer: Single oral temperature ≥38.3°C (101°F) or ≥38°C (100.4°F) sustained, with ANC <500/µL

Neutropenic fever is defined as a single temperature ≥38.3°C or sustained ≥38°C with ANC <500/µL (or expected to fall below 500), requiring immediate broad-spectrum antibiotics.

Question 24: 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:

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

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 25: Which resource allocation strategy in Oncology Nursing Certification Corporation pain management focuses on maximizing output with limited resources?

Acquiring unlimited resources regardless of cost
Optimization of available resources through prioritization (Correct answer)
Delegating resource decisions to external consultants
