Question 1 of 5
When a patient is experiencing digoxin toxicity, which clinical situation would necessitate the use
Correct Answer: D
Rationale: When a patient is experiencing digoxin toxicity, severe sinus bradycardia that does not respond to cardiac pacing is a clinical situation that would necessitate the use of digoxin-specific antibody fragments (Digibind). This intervention is required to counteract the toxic effects of digoxin on the heart, especially in cases of severe bradycardia that can compromise cardiac output and lead to serious consequences. In this scenario, Digibind works by binding to digoxin molecules, thereby neutralizing their effects and helping to restore normal cardiac function.
Question 2 of 5
What should you monitor when given a patient Clopidogrel?
Correct Answer: D
Rationale: When monitoring a patient on Clopidogrel therapy, it is important to monitor for signs of thrombotic thrombolytic purpura (TTP), bleeding during therapy, and changes in blood counts. Clopidogrel is an antiplatelet medication that works by preventing platelets from sticking together and forming clots. Monitoring for signs of TTP is necessary as clopidogrel has been associated with an increased risk of TTP in some patients. Additionally, monitoring for bleeding is crucial as clopidogrel, like other antiplatelet medications, can increase the risk of bleeding complications. Monitoring a complete blood count (CBC) with differential and platelet count allows healthcare providers to assess the patient's blood cell levels and ensure that the medication is not causing any adverse effects on blood counts. Therefore, monitoring all of the above parameters is essential to ensure the safety and efficacy of clopidogrel therapy.
Question 3 of 5
A patient is in the emergency department with new-onset atrial fibrillation. Which order for digoxin would most likely have the fastest therapeutic effect?
Correct Answer: D
Rationale: When a patient requires immediate treatment for atrial fibrillation with digoxin, the fastest way to achieve a therapeutic effect is through intravenous administration. Option D, Digoxin 1 mg IV push now; then 0.25 mg IV daily, is the most appropriate order in this scenario. Intravenous administration allows for rapid absorption and onset of action, making it the preferred route for urgent situations like atrial fibrillation. By giving an initial loading dose intravenously, followed by a lower maintenance dose IV daily or orally, the patient can quickly achieve therapeutic digoxin levels to help stabilize the heart rhythm. Option D provides the most rapid and effective way to manage new-onset atrial fibrillation with digoxin.
Question 4 of 5
Liquid preparation made by boiling vegetable substances with water
Correct Answer: A
Rationale: A decoction is a liquid preparation made by boiling vegetable substances with water. This process helps extract the beneficial properties and compounds from the plant material into the liquid. Decoctions are commonly used in herbal medicine to prepare medicinal remedies by simmering roots, bark, or other plant parts in water for a period of time.
Question 5 of 5
The nurse is teaching a patient about taking aspirin. Which are important points to include? (Select all that apply.)
Correct Answer: D
Rationale: Aspirin is an antiplatelet agent that can increase the risk of bleeding, especially when combined with alcohol or during invasive procedures like dental work or surgery. Patients should avoid alcohol to reduce the risk of gastrointestinal bleeding. Additionally, informing healthcare providers about aspirin use is crucial to prevent excessive bleeding during procedures. Taking aspirin on an empty stomach is not recommended, as it can increase the risk of gastric irritation. Therefore, the correct teaching points are to avoid alcohol, inform the dentist, and inform the surgeon about aspirin use.
