Question 1 of 9
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 2 of 9
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 3 of 9
Route of drug administration where the drug is placed directly into the GIT from where absorption occurs.
Correct Answer: A
Rationale: Enteral route of drug administration involves placing the drug directly into the gastrointestinal tract (such as oral or rectal routes) for absorption into the systemic circulation. This route requires the drug to pass through the digestive system before being absorbed, allowing for slower and more sustained release of the medication compared to other routes. Examples of enteral drug administration include oral tablets, capsules, and liquids as well as rectal suppositories.
Question 4 of 9
A patient is taking Digoxin to slow his heart rate down. The nurse suggests that he take his oral medication:
Correct Answer: A
Rationale: The nurse suggests that the patient takes his Digoxin medication when awakening because it is best absorbed when taken on an empty stomach. Taking Digoxin with meals can decrease its absorption, reducing its effectiveness. Therefore, to ensure optimal absorption and effectiveness of Digoxin in slowing down the heart rate, it is recommended to take it when awakening on an empty stomach.
Question 5 of 9
What nursing interventions should you do when a patient is on Albuterol (select all that apply)
Correct Answer: A
Rationale: A. Assess lung sounds, Pulse, and Blood pressure before administering: Before administering Albuterol, it is crucial to assess the patient's lung sounds, pulse, and blood pressure as baseline data. This helps in monitoring the effects of Albuterol on the respiratory and cardiovascular systems.
Question 6 of 9
A patient is taking Digoxin to slow his heart rate down. The nurse suggests that he take his oral medication:
Correct Answer: A
Rationale: It is recommended for the patient to take Digoxin in the morning when awakening. This is because Digoxin has a long half-life which means it stays in the body for a long period of time. By taking it in the morning, the patient can benefit from its effects throughout the day, including its ability to slow down the heart rate and improve heart function. Additionally, taking it in the morning helps to reduce the risk of potential interactions with other medications or food consumed later in the day.
Question 7 of 9
When a patient is experiencing digoxin toxicity, which clinical situation would necessitate the use
Correct Answer: A
Rationale: A: The patient reports seeing colorful halos around lights is A common symptom of digoxin toxicity that indicates visual disturbances.
Question 8 of 9
Which route should lithium be administered by?
Correct Answer: A
Rationale: Lithium is typically administered orally (PO) for long-term treatment of bipolar disorder. However, in emergency situations or cases of lithium toxicity where rapid control of symptoms is required, lithium can be administered via the intravenous (IV) route for faster absorption and effectiveness. IV administration allows for quick delivery of the medication directly into the bloodstream to achieve therapeutic levels promptly. It is essential to closely monitor lithium levels and kidney function when administering it intravenously to prevent potential complications.
Question 9 of 9
The nurse is reviewing the client's history who is about to take Methotrexate. Which of the following drugs can be safely administered together with methotrexate?
Correct Answer: B
Rationale: Folic acid supplementation is recommended for patients on methotrexate to reduce the risk of side effects such as mucositis and myelosuppression. Tetracycline, sulfamethoxazole, and phenytoin can interact with methotrexate, increasing its toxicity. Folic acid helps mitigate these adverse effects without interfering with the drug's efficacy.
