Question 1 of 5
An oncology nurse recognizes a patient's risk for fluid imbalance while the patient is undergoing treatment for leukemia. What relevant assessments should the nurse include in the patient's plan of care? Select all that apply.
Correct Answer: B
Rationale: The correct answer is B: Monitoring the patient's hepatic function. In leukemia treatment, chemotherapy drugs can affect liver function, leading to fluid imbalance. By monitoring hepatic function, the nurse can assess the liver's ability to regulate fluid balance. A: Monitoring electrolyte levels is important but not directly related to fluid imbalance in leukemia treatment. C: Measuring weight daily is important for fluid status assessment but does not target hepatic function specifically. D: Measuring and recording intake and output is crucial for fluid balance monitoring but does not focus on hepatic function assessment.
Question 2 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: Rationale: Aspirin is an antiplatelet medication that inhibits platelet aggregation, increasing the risk of uncontrolled bleeding during surgical procedures. By taking aspirin, the client's blood clotting ability is impaired, leading to potential excessive bleeding during and after surgery. This can result in complications such as prolonged bleeding, hematoma formation, and delayed wound healing. Therefore, the correct answer is A: Uncontrolled bleeding. Summary: - B: Myocardial infarction is not directly related to taking aspirin; it is actually used to prevent heart attacks. - C: Respiratory depression is not a common complication associated with aspirin use. - D: Decreased renal perfusion is not a typical risk of taking aspirin; it primarily affects the cardiovascular system.
Question 3 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 red blood cell production, which should increase hemoglobin levels. Higher hemoglobin levels indicate improved oxygen-carrying capacity and overall effectiveness of the therapy. PT (A), WBC (B), and Platelets (D) are not directly affected by epoetin therapy, so an increase in these values would not be indicative of the medication's effectiveness.
Question 4 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 is a medication used to stimulate red blood cell production in patients with renal failure. One of the potential adverse effects of epoetin therapy is an increase in blood pressure due to the rapid rise in red blood cell count. This can lead to hypertension. Monitoring for hypertension is crucial to prevent any complications. The other choices, muscle pain, edema, and dry mouth, are not directly associated with epoetin therapy in renal failure patients. Muscle pain could be a general issue but not specific to this medication. Edema is more commonly associated with fluid retention in renal failure, and dry mouth is not a typical adverse effect of epoetin therapy.
Question 5 of 5
Which of the following moves furthest to the anode on cellulose acetate electrophoresis of normal haemoglobin at pH 8.6?
Correct Answer: A
Rationale: 1. In cellulose acetate electrophoresis at pH 8.6, proteins migrate based on their net charge. 2. Haemoglobin A migrates furthest to the anode as it has the highest net negative charge among the options. 3. Haemoglobin D, A2, and S have different charges compared to Haemoglobin A. 4. Haemoglobin D and A2 have lower net negative charges, so they migrate less than Haemoglobin A. 5. Haemoglobin S has a different charge distribution due to a mutation, causing it to migrate differently than Haemoglobin A.
