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. The public health nurse is presenting a health-promotion class to a group at a local community center. Which intervention most directly addresses the leading cause of cancer deaths in North America?

• A. Monthly self-breast exams
• B. Smoking cessation
• C. Annual colonoscopies
• D. Monthly testicular exams

Correct answer: B

Rationale: In North America, lung cancer is the leading cause of cancer deaths among both men and women, and the primary risk factor for lung cancer is smoking. Therefore, promoting smoking cessation is a critical public health intervention that directly addresses this significant health issue. By helping individuals quit smoking, healthcare providers can significantly reduce the incidence of lung cancer and associated deaths, making this intervention a priority in cancer prevention efforts.

3. A patient with myelofibrosis is being treated with ruxolitinib. What should the nurse monitor to assess the effectiveness of this treatment?

• A. Blood pressure
• B. White blood cell count
• C. Hemoglobin and hematocrit
• D. Spleen size

Correct answer: C

Rationale: Monitoring hemoglobin and hematocrit is essential to assess the effectiveness of ruxolitinib in treating myelofibrosis. Ruxolitinib works by inhibiting JAK1 and JAK2, which are involved in the signaling pathways that regulate blood cell production. Therefore, monitoring hemoglobin and hematocrit levels can provide valuable information on how well the drug is managing the disease. Blood pressure, white blood cell count, and spleen size are not direct indicators of the treatment's effectiveness in myelofibrosis.

4. An oncology nurse is caring for a patient who has developed erythema following radiation therapy. What should the nurse instruct the patient to do?

• A. Periodically apply ice to the area.
• B. Keep the area cleanly shaven.
• C. Apply petroleum jelly to the affected area.
• D. Avoid using soap on the treatment area.

Correct answer: D

Rationale: The correct answer is D. When a patient develops erythema following radiation therapy, it is essential to avoid further irritation and potential infection. Using soap on the affected area can exacerbate the condition. Applying ice (choice A) may provide temporary relief for discomfort but does not address the underlying issue. Keeping the area cleanly shaven (choice B) is not necessary and may increase the risk of skin irritation. Applying petroleum jelly (choice C) can trap heat and worsen the erythema, so it is not recommended.

5. As part of chemotherapy education, the nurse teaches a female client about the risk for bleeding and self-care during the period of greatest bone marrow suppression (the nadir). The nurse understands that further teaching is needed if the client makes which statement?

• A. I should avoid blowing my nose.
• B. I may need a platelet transfusion if my platelet count is too low.
• C. I should take aspirin for my headache as soon as I get home.
• D. I will count the number of pads and tampons I use when menstruating.

Correct answer: C

Rationale: The correct answer is C. Taking aspirin is not recommended during periods of bone marrow suppression as it can increase the risk of bleeding. Aspirin is a nonsteroidal anti-inflammatory drug (NSAID) that can impair platelet function, further exacerbating the risk of bleeding. Choices A, B, and D are all appropriate statements for a client at risk for bleeding and undergoing chemotherapy. Blowing the nose gently, being prepared for a platelet transfusion if needed, and monitoring menstrual bleeding are all important aspects of self-care during this period.
