ATI Hematologic System Questions
Question 1 of 5
A nurse should identify that clopidogrel is contraindicated for clients who have which of the following conditions?
Correct Answer: B
Rationale: Clopidogrel is an antiplatelet medication that can increase the risk of bleeding. Patients with peptic ulcer disease are at a higher risk of gastrointestinal bleeding, so clopidogrel is contraindicated. Myocardial infarction, pancreatitis, and myasthenia gravis are not contraindications for clopidogrel use.
Question 2 of 5
A nurse is monitoring a client who is undergoing anticoagulant therapy with heparin. Which of the following findings should the nurse identify as a possible indication of hemorrhage?
Correct Answer: A
Rationale: The correct answer is A: Rapid pulse. When a client is undergoing anticoagulant therapy with heparin, the nurse should monitor for signs of hemorrhage. A rapid pulse can indicate internal bleeding, a common complication of anticoagulant therapy. Other choices such as B: Yellowing of the sclera, C: Elevated blood pressure, and D: Pale-colored stools are not typically associated with hemorrhage. Yellowing of the sclera may indicate jaundice, elevated blood pressure may be related to other conditions, and pale-colored stools may indicate liver or gallbladder issues. Rapid pulse is the most pertinent finding related to hemorrhage in this context.
Question 3 of 5
Which of the following is a cause of secondary neutropaenia in adults?
Correct Answer: C
Rationale: The correct answer is C: Part of general pancytopenia. Secondary neutropenia in adults can occur as part of general pancytopenia, where there is a decrease in all blood cell types. This can be caused by various conditions such as infections, medications, autoimmune disorders, and bone marrow disorders. Rationale: A: Congenital is incorrect because congenital neutropenia refers to a condition present at birth, not secondary neutropenia. B: Anti-hypertensive drugs may cause drug-induced neutropenia, but it is not the primary cause of secondary neutropenia in adults. D: Familial neutropenia is a genetic disorder that runs in families and is not a common cause of secondary neutropenia in adults.
Question 4 of 5
A laboratory finding of aplastic anaemia
Correct Answer: A
Rationale: Rationale: 1. Aplastic anemia is characterized by bone marrow failure, leading to decreased production of all blood cell types. 2. Pancytopenia refers to low levels of red blood cells, white blood cells, and platelets, consistent with aplastic anemia. 3. Erythrocytosis is an increase in red blood cell count, contradictory to the reduced production in aplastic anemia. 4. Bone marrow hypercellularity indicates increased cellularity, opposite to the hypocellularity seen in aplastic anemia. 5. Reticulocytosis is an elevated number of immature red blood cells, which is not typically seen in the context of bone marrow failure in aplastic anemia. Summary: A is correct as it aligns with the characteristic pancytopenia in aplastic anemia. B, C, and D are incorrect due to their inconsistency with the pathophysiology of the condition.
Question 5 of 5
The nurse is explaining the role of red blood cells with oxygen transport in the body with a nursing student. Which term should the nurse use to describe hemoglobin that has given up its oxygen to the body's cells?
Correct Answer: A
Rationale: The correct term to describe hemoglobin that has given up its oxygen to the body's cells is "Reduced." When hemoglobin releases oxygen to the body's cells, it becomes deoxygenated or reduced hemoglobin. This term accurately reflects the chemical state of the hemoglobin molecule after oxygen release. Summary of other choices: - B: "Detached" does not accurately describe the process of oxygen release by hemoglobin. - C: "Oxyhemoglobin" refers to hemoglobin bound to oxygen, not after it has given up oxygen. - D: "Hypoxyhemoglobin" refers to hemoglobin with low oxygen levels, not after it has given up oxygen.
