ATI Pharmacology Assessment 2 Questions
Question 1 of 5
A nurse is giving a patient a loading dose of 1 mg of an antiarrhythmic drug to treat atrial flutters. Which of the following is most likely the drug being administered?
Correct Answer: A
Rationale: Digoxin is commonly used to treat atrial flutter and atrial fibrillation by helping to control the heart rate. A loading dose may be given initially to reach therapeutic levels quickly. This medication acts by increasing the force of the heart's contractions and slowing down the heart rate. Propranolol (Choice B) is a beta-blocker used to treat various heart conditions, but it is not typically used for atrial arrhythmias like atrial flutter. Ibuprofen (Choice C) is a nonsteroidal anti-inflammatory drug used for pain and inflammation, not for cardiac arrhythmias. Lithium (Choice D) is a mood-stabilizing medication often used for bipolar disorder and is not indicated for atrial flutter treatment.
Question 2 of 5
The nurse is giving instructions to a client receiving phenytoin (Dilantin). The nurse concludes that the client has a sufficient knowledge if the client states that:
Correct Answer: D
Rationale: Monitoring serum phenytoin levels is essential to ensure therapeutic efficacy and avoid toxicity. Wearing a medical alert tag is recommended for clients on phenytoin. Alcohol should be avoided, and taking the medication with milk can interfere with absorption. Therefore, the correct statement indicating sufficient knowledge is about monitoring serum levels.
Question 3 of 5
The classi昀椀cation of digoxin is:
Correct Answer: D
Rationale: Digoxin belongs to the class of drugs known as cardiac glycosides. Cardiac glycosides are a group of compounds derived from plants and some animals that have the ability to increase the contractility of the heart muscle. Digoxin is commonly used to treat conditions such as congestive heart failure and irregular heart rhythms. It works by inhibiting the sodium-potassium pump in heart muscle cells, leading to an increase in intracellular calcium levels and subsequently improving the heart's pumping ability.
Question 4 of 5
The nurse has completed medication education with the patient who is receiving risperidone (Risperdal). The nurse evaluates that the education has been effective when the patient makes which statement?
Correct Answer: B
Rationale: Risperidone, an atypical antipsychotic, can cause agranulocytosis, a rare but life-threatening drop in white blood cells, necessitating regular blood monitoring . This statement reflects understanding of a critical safety measure, indicating effective education. Nightmares aren't a primary concern with risperidone. Weight loss contrasts with its common side effect of weight gain, making it less relevant. Metallic taste isn't associated with this drug. The nurse evaluates learning based on recognition of monitoring for severe adverse effects like agranulocytosis, ensuring patient safety, making choice B the best indicator of comprehension.
