ATI LPN
LPN Pharmacology Assessment A Questions
Question 1 of 9
In monitoring the effectiveness of warfarin therapy for a client with a history of atrial fibrillation, which laboratory value should the nurse monitor?
Correct Answer: B
Rationale: Prothrombin time (PT) and international normalized ratio (INR) are crucial laboratory values to monitor the effectiveness of warfarin therapy in clients with atrial fibrillation. These values help ensure that the client is within the therapeutic range and that the anticoagulant effect of warfarin is appropriate.
Question 2 of 9
The client has angina pectoris and is prescribed nitroglycerin patches. What instruction should the nurse provide to the client?
Correct Answer: B
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 3 of 9
A client is receiving intravenous heparin therapy for the treatment of deep vein thrombosis (DVT). Which laboratory test result should the LPN/LVN monitor to ensure the client is receiving a therapeutic dose?
Correct Answer: B
Rationale: The correct laboratory test result that the LPN/LVN should monitor to ensure the client is receiving a therapeutic dose of heparin therapy is the activated partial thromboplastin time (aPTT). The aPTT test is specifically used to monitor heparin therapy, ensuring that the dose administered is within the therapeutic range. Monitoring aPTT helps to prevent complications such as bleeding or clot formation by maintaining the appropriate anticoagulant effect of heparin.
Question 4 of 9
A client with a history of myocardial infarction (MI) is being discharged with a prescription for nitroglycerin sublingual tablets. Which instruction should the nurse reinforce?
Correct Answer: A
Rationale: Nitroglycerin tablets are light and moisture-sensitive, so they should be stored in a cool, dry place away from light to maintain their effectiveness. Option B advises taking a tablet every 5 minutes, which may lead to overdose. Option C emphasizes the correct administration route for sublingual tablets. Option D is incorrect as water is not needed for the tablets to take effect.
Question 5 of 9
A client with a history of deep vein thrombosis (DVT) is prescribed warfarin (Coumadin). The nurse should include which instruction in the discharge teaching?
Correct Answer: A
Rationale: Taking warfarin at the same time each day is crucial to maintain consistent blood levels and ensure the effectiveness of the medication in preventing clot formation. Consistent timing helps in monitoring and adjusting the dosage as needed to keep the international normalized ratio (INR) within the therapeutic range to prevent clotting events or excessive bleeding.
Question 6 of 9
The client is receiving anticoagulant therapy for atrial fibrillation. Which laboratory test should be monitored to determine the effectiveness of the therapy?
Correct Answer: A
Rationale: Prothrombin time (PT) and international normalized ratio (INR) are essential laboratory tests to monitor the effectiveness of anticoagulant therapy in clients with atrial fibrillation. These tests help ensure that the client is within the therapeutic range and are commonly used to assess the clotting ability of the blood. Monitoring PT and INR levels allows healthcare providers to adjust anticoagulant dosages as needed to prevent complications such as bleeding or thrombosis.
Question 7 of 9
The client with a history of coronary artery disease (CAD) is scheduled for a stress test. What instruction should the nurse provide to the client before the test?
Correct Answer: C
Rationale: The correct instruction for the client before a stress test is to wear loose, comfortable clothing, and walking shoes. This is crucial as the stress test involves physical exercise, and the client should be prepared for the activity involved. Beta-blockers may need to be adjusted or held before the test as per healthcare provider's instructions. Fasting before the test is not typically required, and avoiding physical activity for 24 hours beforehand is not necessary and may interfere with the accuracy of the test results.
Question 8 of 9
The nurse is preparing to administer a scheduled dose of enalapril (Vasotec) to a client with hypertension. Before administering the medication, the nurse should check which priority assessment?
Correct Answer: B
Rationale: Before administering enalapril, an antihypertensive medication, the nurse should prioritize checking the client's blood pressure. Monitoring blood pressure helps ensure it is at an acceptable level before giving the medication, as enalapril can further lower blood pressure. This assessment is crucial in preventing potential hypotensive episodes and adverse effects associated with excessive blood pressure reduction.
Question 9 of 9
The nurse is caring for a client receiving anticoagulant therapy. Which instruction should the nurse reinforce with the client to prevent bleeding complications?
Correct Answer: A
Rationale: The correct instruction to prevent bleeding complications in a client on anticoagulant therapy is to use a soft-bristle toothbrush and electric razor. These implements help reduce the risk of bleeding by being gentle on the skin and reducing the chances of cuts or abrasions that could lead to bleeding in individuals on anticoagulants.
