Question 1 of 5
An older adult patient is undergoing diagnostic testing for chronic lymphocytic leukemia (CLL). What assessment finding is certain to be present if the patient has CLL?
Correct Answer: B
Rationale: Step-by-step rationale: 1. CLL is characterized by the proliferation of abnormal lymphocytes. 2. Increased lymphocyte levels are a hallmark of CLL due to the accumulation of these abnormal cells. 3. Lymphocytosis is a key diagnostic feature in CLL. 4. Other choices are incorrect because blast cells are characteristic of acute leukemia, bone pain is more common in multiple myeloma, and thrombocytopenia with no bleeding is not a specific finding in CLL. Summary: Increased lymphocyte levels are certain to be present in a patient with CLL due to the abnormal proliferation of lymphocytes. Other choices are incorrect as they do not align with the characteristic features of CLL.
Question 2 of 5
A nurse is caring for a client who is about to begin alteplase therapy to treat pulmonary embolism. Which of the following drugs should the nurse have available in the event of a severe adverse reaction?
Correct Answer: B
Rationale: The correct answer is B: Aminocaproic acid. This drug is a fibrinolytic inhibitor that can be used to manage bleeding complications associated with alteplase therapy. It helps to prevent excessive bleeding by inhibiting the breakdown of blood clots. Having aminocaproic acid available is crucial in case the client experiences severe bleeding as a result of alteplase therapy. A: Vitamin K is used to reverse the effects of warfarin, a blood thinner, and is not indicated for managing bleeding due to alteplase therapy. C: Protamine is used to reverse the effects of heparin, not alteplase, and is not indicated for managing bleeding due to alteplase therapy. D: Deferoxamine is an antidote for iron poisoning and is not indicated for managing bleeding due to alteplase therapy. In summary, aminocaproic acid is the correct choice as it helps manage bleeding complications associated with alteplase therapy
Question 3 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 4 of 5
A nurse is caring for a client who is about to begin taking folic acid to treat megaloblastic anemia. The nurse should monitor which of the following laboratory values to determine therapeutic effectiveness?
Correct Answer: B
Rationale: The correct answer is B: Reticulocyte count. Reticulocytes are immature red blood cells, and monitoring their count can help determine the effectiveness of folic acid in treating megaloblastic anemia. Increased reticulocyte count indicates improved production of red blood cells. Amylase level, C-reactive protein, and creatinine clearance are not directly related to monitoring the effectiveness of folic acid in treating megaloblastic anemia.
Question 5 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.
