1. A nurse is caring for a client with thrombocytopenia. Which action is the highest priority to reduce the risk of bleeding?
- A. Use an electric razor instead of a straight razor.
- B. Apply pressure to any bleeding sites for at least 5 minutes.
- C. Avoid invasive procedures unless absolutely necessary.
- D. Monitor for signs of internal bleeding.
Correct answer: C
Rationale: The highest priority action to reduce the risk of bleeding in a client with thrombocytopenia is to avoid invasive procedures unless absolutely necessary. Thrombocytopenia is a condition characterized by a low platelet count, which impairs the blood's ability to clot properly. By avoiding invasive procedures, the nurse minimizes the potential for bleeding episodes that could be challenging to control due to the low platelet count. Using an electric razor instead of a straight razor (Choice A) is a good practice to prevent cuts, but it is not as critical as avoiding invasive procedures in this scenario. Applying pressure to bleeding sites (Choice B) and monitoring for signs of internal bleeding (Choice D) are important interventions but are secondary to the priority of preventing bleeding by avoiding invasive procedures.
2. A client in the oncology clinic reports her family is frustrated at her ongoing fatigue 4 months after radiation therapy for breast cancer. What response by the nurse is most appropriate?
- A. Are you getting adequate rest and sleep each day?
- B. It is normal to be fatigued even for months afterward.
- C. This is not normal and I’ll let the primary health care provider know.
- D. Try adding more vitamins B and C to your diet.
Correct answer: B
Rationale: Radiation-induced fatigue can last for months; it’s important to normalize this for the client.
3. A patient’s most recent diagnostic imaging has revealed that his lung cancer has metastasized to his bones and liver. What is the most likely mechanism by which the patient’s cancer cells spread?
- A. Hematologic spread
- B. Lymphatic circulation
- C. Invasion
- D. Angiogenesis
Correct answer: B
Rationale: In the case of lung cancer that has metastasized to the bones and liver, lymphatic circulation is a key mechanism by which cancer cells spread from the primary tumor site to distant organs. Cancer cells can invade nearby lymphatic vessels and travel through the lymphatic system, eventually reaching lymph nodes and spreading to other tissues and organs. This route is significant in the metastasis of many types of cancer, including lung cancer.
4. A patient with a myelodysplastic syndrome is being treated on the medical unit. What assessment finding should prompt the nurse to contact the patients primary care provider?
- A. The patient is experiencing a frontal lobe headache.
- B. The patient has an episode of urinary incontinence.
- C. The patient has an oral temperature of 37.5C (99.5F).
- D. The patients SpO2 is 91% on room air.
Correct answer: C
Rationale: Patients with myelodysplastic syndrome (MDS) have a dysfunctional bone marrow that leads to ineffective blood cell production, including white blood cells, which are crucial for fighting infections. As a result, they are at high risk for infections. Even a slight elevation in temperature, such as 37.5°C (99.5°F), could be an early sign of infection in an immunocompromised patient. Early detection and treatment of infections are critical in MDS patients, as infections can quickly become severe or life-threatening due to their compromised immune system.
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.
