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. 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.

3. A client is having a catheter placed to deliver chemotherapy beads into a liver tumor via the femoral artery. What action by the nurse is most important?

• A. Assessing the client’s abdomen beforehand.
• B. Ensuring that informed consent is on the chart.
• C. Marking the client’s bilateral pedal pulses.
• D. Reviewing client teaching done previously.

Correct answer: B

Rationale: Before any invasive procedure, such as placing a catheter to deliver chemotherapy beads into a liver tumor, it is essential to ensure that informed consent has been obtained from the client. This is a legal and ethical requirement that ensures the client understands the procedure, its risks, benefits, and alternatives. Ensuring that the signed consent is on the chart is the most important action the nurse can take before the procedure, as the procedure cannot legally proceed without it.

4. Four clients are receiving tyrosine kinase inhibitors (TKIs). Which of these four clients would the nurse assess first?

• A. Dry, itchy, peeling skin.
• B. Serum calcium of 9.2 mg/dL (2.3 mmol/L).
• C. Serum potassium of 2.8 mEq/L (2.8 mmol/L).
• D. Weight gain of 0.5 lb (1.1 kg) in 1 day.

Correct answer: C

Rationale: A potassium level of 2.8 mEq/L is critically low and requires immediate intervention.

5. Which of the following is considered correct in dealing with a patient who has gastric cancer?

• A. After total gastrectomy, patient will have to increase fluids during meals
• B. After total gastrectomy, patient will need lots of fiber in the diet
• C. After total gastrectomy, patient will have to walk about after meals
• D. After total gastrectomy, patient will have to lie flat on bed after meals

Correct answer: D

Rationale: After a total gastrectomy, where the entire stomach is removed, patients can experience dumping syndrome due to the rapid passage of food into the small intestine. This condition can lead to symptoms such as nausea, vomiting, diarrhea, and abdominal cramps. Lying flat after meals can help slow down the movement of food into the intestines, reducing the risk of dumping syndrome. It's important for patients to follow dietary recommendations and positioning strategies to manage symptoms effectively.
