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 nurse is preparing to administer filgrastim to a client undergoing chemotherapy. What is the primary purpose of this medication?

• A. Increase white blood cell production.
• B. Reduce the risk of infection.
• C. Enhance red blood cell production.
• D. Control chemotherapy-induced nausea and vomiting.

Correct answer: A

Rationale: Filgrastim is primarily used to increase white blood cell production in clients undergoing chemotherapy.

3. 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.

4. A client with cancer has anorexia and mucositis, and is losing weight. The client’s family members continually bring favorite foods to the client and are distressed when the client won’t eat them. What action by the nurse is best?

• A. Explain the pathophysiologic reasons behind the client not eating.
• B. Help the family show other ways to demonstrate love and caring.
• C. Suggest foods and liquids the client might be willing to try to eat.
• D. Tell the family the client isn’t able to eat now no matter what they bring.

Correct answer: B

Rationale: The best action for the nurse in this situation is to help the family show other ways to demonstrate love and caring. When a client with cancer is experiencing anorexia and mucositis, it can be challenging for them to eat even their favorite foods. By assisting the family in finding alternative ways to provide comfort and care, the nurse can help create a supportive environment for the client. Option A is not the best choice as explaining the pathophysiologic reasons may not address the emotional needs of the client and family. Option C, suggesting foods and liquids, might not be helpful if the client is unable to tolerate them due to their condition. Option D, telling the family that the client can't eat, may come across as dismissive and not supportive of the family's concerns.

5. 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.
