Nursing Elites

1. 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.

2. A nurse is preparing health education for a patient who has received a diagnosis of myelodysplastic syndrome (MDS). Which of the following topics should the nurse prioritize?

• A. Techniques for energy conservation and activity management
• B. Emergency management of bleeding episodes
• C. Technique for the administration of bronchodilators by metered-dose inhaler
• D. Techniques for self-palpation of the lymph nodes

Correct answer: B

Rationale: Because of patients risks of hemorrhage, patients with MDS should be taught techniques for managing emergent bleeding episodes.

3. An oncology patient will begin a course of chemotherapy and radiation therapy for the treatment of bone metastases. What is one means by which malignant disease processes transfer cells from one place to another?

• A. Adhering to primary tumor cells
• B. Inducing mutation of cells of another organ
• C. Phagocytizing healthy cells
• D. Invading healthy host tissues

Correct answer: D

Rationale: The correct answer is D: Invading healthy host tissues. Invasion is the process where malignant cells grow into surrounding healthy tissues, allowing the cancer to spread to other parts of the body. Choices A, B, and C are incorrect. Adhering to primary tumor cells does not involve the transfer of cells to other locations, inducing mutation of cells of another organ is not a mechanism of cell transfer, and phagocytizing healthy cells refers to the process of engulfing and digesting cells, which is not a method of cancer cell transfer.

4. The hospice nurse is caring for a patient with cancer in her home. The nurse has explained to the patient and the family that the patient is at risk for hypercalcemia and has educated them on the signs and symptoms of this health problem. What else should the nurse teach this patient and family to do to reduce the patient’s risk of hypercalcemia?

• A. Stool softeners are contraindicated.
• B. Laxatives should be taken daily.
• C. Consume 2 to 4 L of fluid daily.
• D. Restrict calcium intake.

Correct answer: C

Rationale: The nurse should encourage the patient to consume 2 to 4 liters of fluid daily to reduce the risk of hypercalcemia.

5. A patient admitted with cancer asks the nurse about the difference between chemotherapy and radiation therapy. Which of the following responses by the nurse indicates a need for further teaching?

• A. Chemotherapy kills cancer cells
• B. Radiation therapy can be internal or external
• C. Radiation therapy is often external
• D. Chemotherapy is more likely to kill normal cells

Correct answer: D

Rationale: While chemotherapy does affect normal, healthy cells—particularly those that divide rapidly—it is not "more likely" to kill normal cells compared to cancer cells. Chemotherapy targets rapidly dividing cells, which includes both cancer cells and some normal cells (like those in hair follicles, the gastrointestinal tract, and bone marrow). However, its primary goal is to kill cancer cells, and its effects on normal cells are a side effect, not the main function. Therefore, the statement that chemotherapy is "more likely" to kill normal cells is inaccurate and indicates a need for further teaching.
