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 allows for gradual physical activity, promoting mobility without overwhelming the patient. This option supports the patient's need for movement while considering their current level of fatigue.
A is incorrect because educating the patient about the benefits of exercise may not be feasible or appropriate given the patient's current fatigue levels.
C is incorrect as stair exercises may be too strenuous for a patient experiencing debilitating fatigue, potentially leading to further exhaustion and risk of injury.
D is incorrect because deep breathing and coughing exercises primarily focus on respiratory health and may not directly address the patient's 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 4-year-old child with acute lymphoblastic leukemia is receiving high-dose methotrexate during interim maintenance. He receives ondansetron and арретitant during his stay, which control his nausea and vomiting well. These medications work by inhibiting signaling in which part of the brain?
- A. Vestibular system
- B. Cerebral cortex
- C. Hypothalamus
- D. Vomiting center
Correct Answer: E
Rationale: I'm sorry, but it seems there was a mistake in providing the correct answer. The answer should be D: Vomiting center. Ondansetron and aprepitant work by inhibiting signaling in the vomiting center of the brain, which helps control nausea and vomiting. The vomiting center is located in the medulla oblongata, part of the brainstem responsible for coordinating the vomiting reflex. Choices A, B, and C are incorrect because the vestibular system is involved in balance and spatial orientation, the cerebral cortex is responsible for higher brain functions, and the hypothalamus plays a role in regulating various bodily functions but not directly in controlling vomiting.
A 10-year-old patient with aplastic anemia, who is blood type B negative, is receiving a red blood cell transfusion. About 10 minutes after the transfusion starts, the patient develops anxiety and lower back pain. The transfusion continues for another 5 minutes until it is stopped when he develops a temperature of 40 °C with chills and rigors. A transfusion reaction work-up is most likely to reveal what findings?
- A. Spherocytes on peripheral blood smear
- B. Gram-negative Bacillus on gram stain of remaining RBC unit
- C. Chest x-ray with bilateral pulmonary infiltrates that are new compared to an x-ray done last week
- D. DAT positive for C3
Correct Answer: D
Rationale: The correct answer is D because in this scenario, the patient is experiencing symptoms of a transfusion reaction, likely a hemolytic transfusion reaction due to ABO incompatibility. The presence of a positive Direct Antiglobulin Test (DAT) for C3 indicates complement activation, supporting the diagnosis.
Choice A (Spherocytes on peripheral blood smear) is incorrect as spherocytes are seen in autoimmune hemolytic anemia, not typically in transfusion reactions.
Choice B (Gram-negative Bacillus on gram stain of remaining RBC unit) is unlikely as the symptoms are more indicative of a hemolytic reaction rather than an infection.
Choice C (Chest x-ray with bilateral pulmonary infiltrates) is suggestive of transfusion-related acute lung injury (TRALI), but the symptoms described in the question (fever, chills, rigors) are more indicative of a hemolytic reaction rather than TRALI.
While taking a client history, which factor(s) that place the client at risk for a hematologic health problem will the nurse document? (Select all that apply.)
- A. Family history of military excellence
- B. Diet low in iron and protein
- C. Excessive alcohol consumption
- D. Family history of allergies
Correct Answer: C
Rationale: The correct answer is C: Excessive alcohol consumption. Excessive alcohol intake can lead to hematologic health problems such as anemia and abnormal blood clotting. Alcohol interferes with the production of red blood cells and impairs the function of platelets. Therefore, documenting excessive alcohol consumption is crucial in assessing a client's risk for hematologic issues.
Explanation for why other choices are incorrect:
A: Family history of military excellence - This choice is irrelevant to hematologic health problems and does not pose a risk factor.
B: Diet low in iron and protein - While a poor diet can contribute to hematologic issues, this specific choice does not directly indicate a risk factor for hematologic problems.
D: Family history of allergies - Allergies are not directly related to hematologic health problems, so this choice is not relevant in this context.
Splenectomy is contraindicated in:
- A. pyruvate kinase def.
- B. ITP
- C. BM failure
- D. angiogenic myeloid metaplasia
Correct Answer: C
Rationale: The correct answer is C: BM failure. Splenectomy is contraindicated in patients with bone marrow failure due to conditions such as aplastic anemia or myelodysplastic syndromes. The spleen plays a role in removing abnormal blood cells, and removing it can worsen cytopenias in these patients. Choices A, B, and D are not contraindications for splenectomy as they do not directly involve the bone marrow function. Pyruvate kinase deficiency (A) does not affect bone marrow function, ITP (B) is a platelet disorder, and angiogenic myeloid metaplasia (D) is a condition related to abnormal blood cell production, not bone marrow failure.
