Question 1 of 5
A nurse is preparing to administer a scheduled dose of warfarin to a client. Which of the following laboratory tests should the nurse review prior to administration?
Correct Answer: B
Rationale: The correct answer is B: PT. The nurse should review the PT (Prothrombin Time) before administering warfarin because warfarin is an anticoagulant medication that works by inhibiting clotting factors. PT measures the extrinsic and common pathways of the coagulation cascade, which are affected by warfarin. Elevated PT indicates a risk of bleeding due to excessive anticoagulation. The other choices are incorrect because:
A) PTT assesses the intrinsic pathway of coagulation, not directly affected by warfarin.
C)
Total iron-binding capacity is unrelated to warfarin therapy.
D) WBC (White Blood Cell count) assesses immune function, not relevant for warfarin administration.
Question 2 of 5
A nurse is assessing a client who has heart failure and is taking furosemide. Which of the following findings should indicate to the nurse that the client is experiencing fluid volume deficit?
Correct Answer: A
Rationale: The correct answer is A: Elevated hematocrit level. When a client is experiencing fluid volume deficit, there is a decrease in circulating blood volume, leading to hemoconcentration. This results in an elevated hematocrit level due to the increased concentration of red blood cells in the blood. A weight gain (
B) would be indicative of fluid volume excess rather than deficit. Shortness of breath (
C) and distended neck veins (
D) are signs of fluid volume overload, not deficit.
Question 3 of 5
A nurse is preparing to administer medications to a client and notices the wrong medication was administered on the previous shift. Which of the following actions should the nurse take first after obtaining vital signs?
Correct Answer: D
Rationale: The correct action is to inform the client's provider first because it is crucial to address the error promptly to ensure the client's safety. By informing the provider, the nurse can obtain guidance on how to proceed with the situation, such as monitoring the client for adverse effects or administering any necessary interventions. This step prioritizes the client's well-being and ensures that appropriate measures are taken promptly. Completing an incident report, documenting findings, and notifying the nursing manager can be important follow-up steps, but they should come after informing the provider to address the immediate concern.
Question 4 of 5
A nurse is reviewing the laboratory data of a client who is receiving filgrastim. Which of the following laboratory values should the nurse monitor to evaluate the effectiveness of the treatment?
Correct Answer: B
Rationale: The correct answer is B: WBC count. Filgrastim is a medication that stimulates the production of white blood cells (WBCs). Monitoring the WBC count is essential to evaluate the effectiveness of the treatment as an increase in WBC count indicates the medication is working to boost the immune system.
Incorrect options:
A: INR (International Normalized Ratio) is used to monitor the effectiveness of anticoagulant therapy, not filgrastim.
C: Potassium level monitoring is important for clients taking certain medications that can affect potassium levels, but not specifically for evaluating the effectiveness of filgrastim.
D: BUN (Blood Urea Nitrogen) is a measure of kidney function and hydration status, not related to evaluating the effectiveness of filgrastim.
Question 5 of 5
A nurse is assessing a client who is receiving a peripheral IV infusion and notes infiltration of fluid into the tissues surrounding the insertion site. Which of the following actions should the nurse take?
Correct Answer: D
Rationale: The correct answer is D: Elevate the extremity. Elevating the extremity helps to reduce swelling at the infiltration site by promoting fluid drainage and decreasing tissue damage. It aids in preventing further infiltration and promotes proper circulation. Slowing the infusion rate (
A) may not be sufficient to address the existing infiltration. Flushing the IV catheter (
B) may worsen the infiltration by pushing more fluid into the tissue. Applying pressure (
C) may not be effective and could cause discomfort. In summary, elevating the extremity is the most appropriate action to manage infiltration.
