A nurse is caring for a client who is taking clopidogrel to prevent stent restenosis. The nurse should monitor the client for which of the following adverse reactions?
- A. Hyperuricemia
- B. Hyponatremia
- C. Lymphocytopenia
- D. Thrombocytopenia
Correct Answer: D
Rationale: The correct answer is D: Thrombocytopenia. Clopidogrel is an antiplatelet medication that works by inhibiting platelet aggregation. Therefore, monitoring for thrombocytopenia, a decrease in platelet count, is crucial to assess the drug's effectiveness and potential side effects. Hyperuricemia (A) is not directly associated with clopidogrel use. Hyponatremia (B) is not a common adverse reaction of clopidogrel. Lymphocytopenia (C) is not typically linked to clopidogrel and is more commonly seen with other medications or conditions.

Best tit modality in CML is:
- A. hydroxyurea
- B. allogenic BMT
- C. interferon alpha
- D. radiotherapy
Correct Answer: B
Rationale: The best treatment modality for chronic myeloid leukemia (CML) is allogenic bone marrow transplantation (BMT) because it offers the potential for cure by replacing the abnormal cells with healthy donor cells. This is the only option that can provide long-term disease control and potential cure for CML. Hydroxyurea (choice A) is a cytotoxic drug used for symptom control but does not target the underlying cause. Interferon alpha (choice C) can help control the disease but is less effective in achieving long-term remission compared to BMT. Radiotherapy (choice D) is not a standard treatment for CML and is not curative.
A patient who is taking warfarin (Coumadin) 5 mg daily has an international normalized ratio (INR) of 2.5. It is time to administer the next dose of Coumadin. What should the nurse do?
- A. Notify the physician STAT.
- B. Hold the dose of Coumadin.
- C. Prepare to administer vitamin K.
- D. Administer the daily Coumadin as ordered.
Correct Answer: D
Rationale: The correct answer is D: Administer the daily Coumadin as ordered. A therapeutic INR range for patients on warfarin is typically between 2-3. A patient with an INR of 2.5 is within this range, indicating that their blood is adequately anticoagulated. Therefore, the next dose of Coumadin should be administered as prescribed to maintain the therapeutic effect. Holding the dose (B) may lead to subtherapeutic anticoagulation, and notifying the physician (A) is not necessary as the INR is within range. Administering vitamin K (C) is indicated for patients with a high INR and signs of bleeding, which is not the case here.
A patient who is undergoing consolidation therapy for the treatment of leukemia has been experiencing debilitating fatigue. How can the nurse best meet this patient's needs for physical activity?
- A. Teach the patient about the risks of immobility and the benefits of exercise.
- B. Assist the patient to a chair during awake times, as tolerated.
- C. Collaborate with the physical therapist to arrange for stair exercises.
- D. Teach the patient to perform deep breathing and coughing exercises.
Correct Answer: B
Rationale: The correct answer is B because assisting the patient to a chair during awake times, as tolerated, is the most appropriate intervention for a patient experiencing debilitating fatigue during consolidation therapy for leukemia. This option promotes mobility and prevents further deconditioning without overwhelming the patient.
A: Teaching about risks and benefits may not directly address the immediate need for physical activity.
C: Stair exercises may be too strenuous for a fatigued patient and could potentially exacerbate their condition.
D: Deep breathing and coughing exercises are important but do not directly address the need for physical activity to combat fatigue.
A patient with a diagnosis of acute myeloid leukemia (AML) is being treated with induction therapy on the oncology unit. What nursing action should be prioritized in the patient's care plan?
- A. Protective isolation and vigilant use of standard precautions
- B. Provision of a high-calorie, low-texture diet and appropriate oral hygiene
- C. Including the family in planning the patient's activities of daily living
- D. Monitoring and treating the patient's pain
Correct Answer: A
Rationale: The correct answer is A: Protective isolation and vigilant use of standard precautions. This is the priority because patients with AML are at high risk for infections due to compromised immune systems. Isolation and strict infection control measures help prevent exposure to pathogens. B is incorrect as the main priority is infection prevention, not diet. C is incorrect as involving the family is important but not the priority. D is incorrect as pain monitoring is important but not the priority in this case.
A 72-year-old male with enlargement of superficial lymph nodes and mild hepatosplenomegaly is diagnosed as having chronic lymphatic leukemia (CLL). The most important criteria for diagnosis of this disease is the
- A. Presence of hypogammaglobulinemia
- B. Absolute lymphocytes
- C. Male predominance
- D. Presence of enlarged lymph nodes
Correct Answer: B
Rationale: The correct answer is B: Absolute lymphocytes. In CLL, the most important diagnostic criterion is an absolute lymphocyte count of more than 5,000 cells per microliter in the peripheral blood. This is a key feature of CLL and distinguishes it from other conditions. Hypogammaglobulinemia (choice A) may occur in CLL but is not as specific for diagnosis. Male predominance (choice C) is a general characteristic of CLL but is not a diagnostic criterion. Presence of enlarged lymph nodes (choice D) is a common manifestation of CLL but not the most important criteria for diagnosis.
