Question 1 of 5
A client has a new prescription for Ondansetron. Which of the following statements should the nurse include?
Correct Answer: A
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 of 5
A nurse is caring for a client with a history of overdosage of aspirin. The nurse suspects which of the following can be an early sign of aspirin toxicity?
Correct Answer: D
Rationale: Tinnitus (ringing in the ears) is an early sign of aspirin toxicity. Aspirin poisoning can cause salicylate intoxication, which includes symptoms like tinnitus, nausea, vomiting, confusion, rapid breathing, and sweating. Other signs of aspirin toxicity may include respiratory alkalosis, metabolic acidosis, hyperthermia, and even seizures. Monitoring for tinnitus is important in clients who may have aspirin toxicity as it serves as an early warning sign to prevent further complications.
Question 3 of 5
A patient has been ordered the powdered form of the bile acid sequestrant colestipol. Which of the following does the nurse identify as true?
Correct Answer: D
Rationale: The nurse should identify that colestipol should be administered 1 hour before or 4 to 6 hours after any other oral medication. This is because colestipol can interfere with the absorption of other medications due to its binding properties in the gut. Administering it separately from other medications helps to avoid any potential interaction and ensures the effectiveness of both the colestipol and other medications. Additionally, colestipol is typically taken with meals to enhance its tolerability and effectiveness in lowering cholesterol levels.
Question 4 of 5
A patient will be receiving a thrombolytic drug as part of the treatment for acute myocardial infarction. The nurse explains to the patient that this drug is used for which purpose?
Correct Answer: C
Rationale: Thrombolytic drugs, also known as clot busters, are used to dissolve blood clots, specifically in the coronary artery for patients with acute myocardial infarction (heart attack). These medications work by activating the body's natural plasminogen system to break down the clot and restore blood flow to the heart muscle. By helping to dissolve the clot, thrombolytic therapy can help to minimize damage to the heart muscle and improve the patient's outcome following a heart attack. It is crucial for patients to receive this treatment promptly after the onset of symptoms for the best chance of success.
Question 5 of 5
When converting from IV heparin to oral warfarin (Coumadin) therapy, the prescriber monitors which of the following to determine the next appropriate dose of warfarin?
Correct Answer: D
Rationale: When converting from IV heparin to oral warfarin therapy, the prescriber monitors the Prothrombin Time (PT) and International Normalized Ratio (INR) to determine the next appropriate dose of warfarin. PT measures the time it takes for blood to clot and INR helps standardize PT results. These tests are crucial in evaluating and adjusting the dosage of warfarin to achieve the desired anticoagulant effect while minimizing the risk of bleeding. Monitoring PT/INR levels regularly is essential to ensure that the patient receives the correct dose of warfarin for their specific condition and to prevent complications. Platelet levels, aPTT, and red blood cell count are not typically used to monitor warfarin therapy.
