Nursing Elites

1. A 54-year-old has a diagnosis of breast cancer and is tearfully discussing her diagnosis with the nurse. The patient states, 'They tell me my cancer is malignant, while my coworker's breast tumor was benign. I just don't understand at all.' When preparing a response to this patient, the nurse should be cognizant of what characteristic that distinguishes malignant cells from benign cells of the same tissue type?

• A. Slow rate of mitosis of cancer cells
• B. Different proteins in the cell membrane
• C. Differing size of the cells
• D. Different molecular structure in the cells

Correct answer: B

Rationale: The correct answer is B. Malignant cells have different proteins in their membranes, such as tumor-specific antigens, which distinguish them from benign cells. Choice A is incorrect as cancer cells typically have a rapid and uncontrolled rate of mitosis. Choice C is incorrect as the size of cells alone does not distinguish between malignant and benign cells. Choice D is incorrect as the molecular structure is not the primary characteristic that distinguishes between malignant and benign cells.

2. A client hospitalized for chemotherapy has a hemoglobin of 6.1 mg/dL (61 mmol/L). The client is symptomatic but refuses blood transfusions. What medication does the nurse prepare to administer?

• A. Epoetin alfa.
• B. Filgrastim.
• C. Mesna.
• D. Dexrazoxane.

Correct answer: A

Rationale: Epoetin alfa stimulates the production of red blood cells, which is important for a client who refuses blood transfusions.

3. The cells of a normal individual can replicate in a specified rate. If the rate of replication becomes uncontrollable, which of the following is lacking from the patient?

• A. Apoptosis
• B. Contact inhibition
• C. Stable cells
• D. Labile cells

Correct answer: B

Rationale: Contact inhibition is a regulatory mechanism that prevents cells from proliferating once they reach a certain density. Normally, when cells grow and touch each other (such as in a monolayer), they stop dividing, maintaining tissue integrity and structure. When contact inhibition is lacking, as in many cancerous cells, cells continue to grow and divide uncontrollably, leading to tumor formation. This loss of regulation is a hallmark of cancerous growth.

4. You are caring for a patient who has just been told that her stage IV colon cancer has recurred and metastasized to the liver. The oncologist offers the patient the option of surgery to treat the progression of this disease. What type of surgery does the oncologist offer?

• A. Palliative
• B. Reconstructive
• C. Salvage
• D. Prophylactic

Correct answer: A

Rationale: The correct answer is A: Palliative. Palliative surgery is aimed at relieving symptoms and improving quality of life when a cure is not possible. In this scenario, where the cancer has recurred and metastasized, the goal of surgery would be to alleviate symptoms rather than to cure the disease. Choices B, C, and D are incorrect because reconstructive surgery aims to restore function or appearance, salvage surgery aims to remove or salvage tissue to prevent further complications, and prophylactic surgery aims to prevent the development of a condition rather than treat its progression.

5. An oncology nurse educator is providing health education to a patient who has been diagnosed with skin cancer. The patient’s wife has asked about the differences between normal cells and cancer cells. What characteristic of a cancer cell should the educator cite?

• A. Malignant cells contain more fibronectin than normal body cells.
• B. Malignant cells contain proteins called tumor-specific antigens.
• C. Chromosomes contained in cancer cells are more durable and stable than those of normal cells.
• D. The nuclei of cancer cells are unusually large, but regularly shaped.

Correct answer: B

Rationale: Malignant (cancer) cells often express tumor-specific antigens (TSAs), which are proteins or markers on the surface of cancer cells that are not found on normal cells. These antigens are produced due to genetic mutations in cancer cells and can sometimes be used to help the immune system recognize and attack cancerous cells. Tumor-specific antigens play a key role in cancer diagnosis, monitoring, and targeted therapies.
