Nursing Elites

1. A client is receiving rituximab and asks how it works. What response by the nurse is best?

• A. It causes rapid lysis of the cancer cell membranes.
• B. It destroys the enzymes needed to create cancer cells.
• C. It prevents the start of cell division in the cancer cells.
• D. It sensitizes certain cancer cells to chemotherapy.

Correct answer: C

Rationale: Rituximab is a monoclonal antibody that targets CD20, a protein found on the surface of certain B-cells, including some cancerous B-cells, such as in non-Hodgkin's lymphoma and chronic lymphocytic leukemia (CLL). Rituximab works by binding to the CD20 protein, which leads to the destruction of the cancerous B-cells through various mechanisms, including preventing the initiation of cell division. By blocking the division process, rituximab helps slow the growth and proliferation of cancer cells, allowing the immune system and additional treatments to clear them more effectively.

2. Nurse Casey is preparing to administer chemotherapy to a client with leukemia. The nurse wears gloves and a gown to administer the medication and to prevent exposure to the agent by which of the following routes?

• A. By ingestion
• B. By skin contact
• C. By absorption
• D. By inhalation

Correct answer: D

Rationale: Chemotherapeutic agents can be hazardous to healthcare workers if they are exposed to the drugs during preparation or administration. One of the primary risks is inhalation, where small particles or aerosols of the drug can become airborne and be inhaled, potentially causing harm to the nurse. Protective gear such as gloves and a gown, as well as masks or respirators in some cases, helps prevent this type of exposure.

3. The nurse is caring for a client following radical neck dissection and creation of a tracheostomy. Which assessment finding would indicate an immediate need for intervention?

• A. Frequent swallowing
• B. Presence of mucous membranes
• C. Bubbling in the water-seal chamber
• D. Inspiratory stridor

Correct answer: D

Rationale: Inspiratory stridor is the correct answer as it suggests airway obstruction, a critical issue requiring immediate intervention. Frequent swallowing (choice A) is a common postoperative finding and does not indicate an immediate need for intervention. The presence of mucous membranes (choice B) is a normal finding and does not require immediate intervention. Bubbling in the water-seal chamber (choice C) of a chest tube drainage system is an expected finding and indicates proper functioning of the system, not an immediate need for intervention.

4. A nurse is creating a plan of care for an oncology patient and one of the identified nursing diagnoses is risk for infection related to myelosuppression. What intervention addresses the leading cause of infection-related death in oncology patients?

• A. Encourage several small meals daily.
• B. Provide skin care to maintain skin integrity.
• C. Assist the patient with hygiene, as needed.
• D. Assess the integrity of the patient’s oral mucosa regularly.

Correct answer: B

Rationale: In oncology patients, particularly those undergoing chemotherapy or radiation therapy, myelosuppression (the decrease in bone marrow activity that leads to reduced white blood cells, red blood cells, and platelets) increases the risk of infection. Maintaining skin integrity is crucial because the skin acts as the body's first line of defense against infections. If the skin becomes compromised, such as through radiation burns, rashes, or breakdowns, it provides a potential entry point for pathogens, increasing the risk of infection. Since infections in oncology patients can quickly become severe due to their weakened immune systems, maintaining skin integrity is a critical intervention to reduce infection risk, especially for patients who are immunosuppressed.

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.
