Question 1 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: In a patient with new-onset atrial fibrillation who requires rapid initiation of digoxin therapy, the fastest therapeutic effect would be achieved by administering the loading dose intravenously. Option D (Digoxin 1 mg IV push now; then 0.25 mg IV daily) includes an initial IV loading dose of 1 mg, followed by a maintenance dose of 0.25 mg IV daily. IV administration allows for quicker absorption and onset of action compared to oral administration. This loading dose increases the digoxin concentration in the bloodstream more rapidly, leading to a quicker therapeutic effect. Subsequent maintenance doses can then be given orally for long-term management.

Question 3 of 5
A patient with a known history of angina was walking his dog and developed chest pain. The patient immediately stops walking and sits down. He continues to experience chest pain when sitting down. When should he call 911?
Correct Answer: A
Rationale: The patient should call 911 immediately. Angina is characterized by chest pain or discomfort that occurs when the heart muscle does not receive enough oxygen-rich blood. The fact that the patient continued to experience chest pain even while sitting down is concerning and suggests that he may be having an acute coronary event, such as a heart attack. In this situation, prompt medical attention is crucial to assess and manage the situation appropriately. It is important not to delay seeking emergency help when experiencing chest pain, especially for a patient with a known history of angina.
Question 4 of 5
The nurse is reviewing discharge teaching for a patient who will be taking digoxin (Lanoxin) therapy. The nurse will teach the patient to avoid which foods when taking the digoxin?
Correct Answer: A
Rationale: Consuming high amounts of foods rich in potassium, such as leafy green vegetables, can potentially decrease the effectiveness of digoxin. Digoxin works by helping the heart beat more strongly and regularly, but too much potassium in the body can interfere with its action.
Therefore, patients taking digoxin are usually advised to avoid consuming excessive amounts of foods high in potassium, such as leafy green vegetables. It is recommended for patients on digoxin therapy to maintain a consistent level of potassium in their diet and follow their healthcare provider's guidance on dietary restrictions.
Question 5 of 5
A patient is being educated on taking levothyroxine, a drug used to balance thyroid activity. What should you include in their education?
Correct Answer: B
Rationale: It is important to educate the patient to take levothyroxine at the same time every day, preferably in the morning on an empty stomach. Consistency in timing helps to maintain stable levels of the medication in the body and optimize its effectiveness in balancing thyroid activity. This medication should not be taken with food, vitamins, or other medications that can interfere with its absorption. Regular thyroid tests are necessary to monitor the effectiveness of the medication and adjust the dosage as needed. If a patient has experienced a recent myocardial infarction or heart attack, it is crucial to consult with healthcare professionals before starting or continuing levothyroxine, as it can have implications on cardiovascular health. It is never advisable for patients to avoid consulting their healthcare professionals if they experience any adverse effects or have concerns about their medication.
