ATI Hematologic System Questions
Question 1 of 5
Haemolytic anemia is not produced by:
Correct Answer: B
Rationale: The correct answer is B: lithium. Lithium does not cause hemolytic anemia because it does not affect red blood cell destruction. Penicillin (A), Quinidine (C), and Methyldopa (D) are known to cause hemolytic anemia by various mechanisms, such as immune-mediated destruction or oxidative damage to red blood cells. In contrast, lithium's mechanism of action does not involve direct harm to red blood cells, making it the correct choice in this scenario.
Question 2 of 5
Sickle cell an. Is not complicated by:
Correct Answer: B
Rationale: Step-by-step rationale for choice B (pancreatitis) being correct: 1. Sickle cell anemia primarily affects red blood cells, leading to vaso-occlusive crises. 2. Pancreatitis is not a known complication of sickle cell anemia. 3. Complications of sickle cell anemia commonly involve organs affected by sickling, such as the bones (osteomyelitis), kidneys (papillary necrosis), and heart (CHF). Summary: A: Papillary necrosis - Correct, as it can affect the kidneys in sickle cell anemia. B: Pancreatitis - Correct, as it is not a typical complication of sickle cell anemia. C: Osteomyelitis - Incorrect, as it can affect the bones in sickle cell anemia. D: CHF - Incorrect, as it can affect the heart in sickle cell anemia.
Question 3 of 5
Macrocytosis is a characteristic of all except:
Correct Answer: D
Rationale: Macrocytosis is characterized by enlarged red blood cells. In Systemic Lupus Erythematosus (SLE), macrocytosis is not a typical finding. The other conditions listed - anemia of myxedema, methotrexate-induced macrocytosis, and macrocytosis due to chronic alcoholism-induced liver disease - are associated with macrocytosis due to various underlying mechanisms. Therefore, the correct answer is D, as macrocytosis is not a characteristic feature of SLE.
Question 4 of 5
An oncology nurse is caring for a patient with multiple myeloma who is experiencing bone destruction. When reviewing the patient's most recent blood tests, the nurse should anticipate what imbalance?
Correct Answer: A
Rationale: The correct answer is A: Hypercalcemia. In multiple myeloma, bone destruction releases calcium into the bloodstream, leading to hypercalcemia. Elevated serum viscosity (C) is not typically associated with multiple myeloma. Hyperproteinemia (B) may be present due to increased production of abnormal proteins, but it does not directly cause bone destruction. Elevated RBC count (D) is not a common finding in multiple myeloma and is not directly related to bone destruction.
Question 5 of 5
A patient with leukemia has developed stomatitis and is experiencing a nutritional deficit. An oral anesthetic has consequently been prescribed. What health education should the nurse provide to the patient?
Correct Answer: A
Rationale: The correct answer is A: Chew with care to avoid inadvertently biting the tongue. Stomatitis causes inflammation in the mouth, making it painful to eat. By chewing carefully, the patient can prevent accidentally biting the tongue or cheek, which can worsen the pain. Using the oral anesthetic before meals (choice B) may provide some relief, but the key is to prevent further injury. Brushing teeth before and after eating (choice C) and swallowing slowly (choice D) do not directly address the issue of preventing accidental bites and are not as essential for managing stomatitis.
