Question 1 of 5
A nurse is caring for a patient who has been diagnosed with leukemia. The nurse's most recent assessment reveals the presence of ecchymoses on the patient's sacral area and petechiae in her forearms. In addition to informing the patient's primary care provider, the nurse should perform what action?
Correct Answer: B
Rationale: Step-by-step rationale for why answer B is correct: 1. Petechiae and ecchymoses indicate potential thrombocytopenia in a leukemia patient. 2. Checking the patient's platelet level will confirm thrombocytopenia and guide treatment. 3. Low platelet levels can lead to bleeding complications, hence the importance of monitoring. 4. Prompt intervention based on platelet level results can prevent worsening complications. Summary of why other choices are incorrect: A: Initiating measures to prevent VTE is not directly related to the patient's current presentation of ecchymoses and petechiae. C: Placing the patient on protective isolation is not indicated for thrombocytopenia. D: Ambulating the patient may be beneficial for circulation but does not address the underlying issue of potential thrombocytopenia.
Question 2 of 5
A nurse is caring for a client who has hemophilia A and is about to begin taking desmopressin to prevent bleeding. The nurse should monitor the client for which of the following adverse reactions?
Correct Answer: B
Rationale: The correct answer is B: Edema. Desmopressin is a medication that can cause fluid retention, leading to edema. Hemophilia A clients are at risk for bleeding, so desmopressin is given to improve clotting. Weight loss (A), polyuria (C), and bradycardia (D) are not common adverse reactions of desmopressin. Weight loss and polyuria are more associated with diabetes insipidus, a condition that desmopressin is used to treat. Bradycardia is not a typical adverse reaction of desmopressin.
Question 3 of 5
A nurse is caring for a client who is scheduled for an outpatient surgical procedure and reports taking aspirin 81 mg daily, including this morning. The nurse should identify that this places the client at risk for which of the following complications?
Correct Answer: A
Rationale: The correct answer is A: Uncontrolled bleeding. Aspirin is an antiplatelet medication that inhibits platelet aggregation, leading to decreased clotting ability. This places the client at risk for uncontrolled bleeding during and after surgery. Myocardial infarction (B) is not directly associated with aspirin use. Respiratory depression (C) is not a common complication of aspirin. Decreased renal perfusion (D) is not a typical complication of aspirin use.
Question 4 of 5
A nurse is caring for a client who is about to begin taking epoetin. An increase in which of the following laboratory values should indicate to the nurse that the therapy is effective?
Correct Answer: C
Rationale: The correct answer is C: Hgb (hemoglobin). Epoetin is a medication used to stimulate the production of red blood cells, which contain hemoglobin. Therefore, an increase in hemoglobin level indicates that the therapy is effective in treating anemia. Incorrect choices: A: PT (prothrombin time) is a measure of blood clotting time and is not directly related to epoetin therapy. B: WBC (white blood cell count) is not affected by epoetin therapy, as it primarily targets red blood cell production. D: Platelets are involved in blood clotting and are not directly influenced by epoetin therapy for anemia. In summary, the increase in hemoglobin level is the most relevant indicator of the effectiveness of epoetin therapy for treating anemia.
Question 5 of 5
A nurse is caring for a client who has renal failure and is receiving epoetin. The nurse should monitor the client for which of the following adverse effects?
Correct Answer: A
Rationale: The correct answer is A: Hypertension. Epoetin stimulates red blood cell production, increasing blood volume and potentially leading to hypertension. This adverse effect is known as hypertensive crisis. Muscle pain (B), edema (C), and dry mouth (D) are not typically associated with epoetin therapy for renal failure. Thus, they are incorrect choices.
