ATI Pharmacology Practice Exam A Questions
Question 1 of 9
Following a stroke, a client has been started on clopidogrel (Plavix). Why is this medication being administered?
Correct Answer: D
Rationale: Clopidogrel (Plavix) is an antiplatelet medication that inhibits platelet aggregation, reducing the risk of blood clots. It is commonly used in patients who have had a stroke and cannot tolerate aspirin due to allergies or intolerances. Choosing clopidogrel in these cases helps prevent further clot formation and reduces the risk of recurrent strokes.
Question 2 of 9
A client presents in the Emergency Department with a suspected MI. Which medication should NOT be given as soon as possible?
Correct Answer: A
Rationale: In the setting of a suspected myocardial infarction (MI), the priority medications to administer as soon as possible include aspirin (ASA) and possibly morphine to manage pain and anxiety. Clopidogrel (Plavix) is not typically administered immediately in the emergency setting for MI management. Metoprolol (Lopressor) is indicated after aspirin administration and stabilization of the patient. Therefore, in this scenario, clopidogrel should NOT be given as a first-line medication for a suspected MI.
Question 3 of 9
A client taking nitroglycerin (Nitrostat) complains of a headache. Which conclusion is most appropriate by the nurse?
Correct Answer: D
Rationale: Nitroglycerin is known to cause headaches as a common side effect due to its vasodilatory properties. It dilates blood vessels, which can lead to headaches. While a headache can indicate other serious conditions, the most common association with nitroglycerin use is a headache. It is crucial for the nurse to recognize this side effect and provide appropriate education and support to the client.
Question 4 of 9
Why should the nitrate patch be off for 8 hours per day?
Correct Answer: D
Rationale: Removing the nitrate patch for 8 hours each day is essential to prevent the body from developing tolerance to the medication. By allowing the body to have a drug-free period, the effectiveness of the medication is maintained over time. This practice helps in ensuring that the nitrate patch continues to provide its intended therapeutic effects without diminishing its efficacy. Therefore, it is important for the client to adhere to the prescribed schedule of removing the patch for 8 hours daily to optimize the treatment outcomes.
Question 5 of 9
Following a stroke, a client has been started on clopidogrel (Plavix). Why is this medication being administered?
Correct Answer: D
Rationale: Clopidogrel (Plavix) is an antiplatelet medication that inhibits platelet aggregation, reducing the risk of blood clots. It is commonly used in patients who have had a stroke and cannot tolerate aspirin due to allergies or intolerances. Choosing clopidogrel in these cases helps prevent further clot formation and reduces the risk of recurrent strokes.
Question 6 of 9
How can the nurse best explain the difference between angina and a myocardial infarction to a client presenting with severe chest pain?
Correct Answer: A
Rationale: When educating a client about the differences between angina and a myocardial infarction, it is crucial to emphasize key distinguishing factors. Angina typically improves with rest and is not usually life-threatening, whereas a myocardial infarction requires urgent intervention as it can be life-threatening. This explanation helps the client understand the urgency and severity associated with a myocardial infarction compared to angina.
Question 7 of 9
Which drug classes are NOT typically used to treat angina?
Correct Answer: C
Rationale: Angina is primarily treated with calcium channel blockers, organic nitrates, and beta blockers. Alpha blockers are not commonly used in the treatment of angina. Calcium channel blockers help dilate blood vessels, decreasing the workload on the heart. Organic nitrates relax and widen blood vessels, improving blood flow and reducing the heart's workload. Beta blockers reduce the heart rate and blood pressure, decreasing the heart's demand for oxygen. Alpha blockers are more commonly used to treat conditions like hypertension and benign prostatic hyperplasia.
Question 8 of 9
When a client is discharged with nitroglycerin (Nitrostat), what should the nurse include in client education?
Correct Answer: B
Rationale: The correct answer instructs the client on the appropriate use of nitroglycerin. Nitroglycerin is used to relieve chest pain or angina. If the chest pain does not subside after taking one tablet, the client should take a maximum of three tablets at 5-minute intervals. If the pain persists after three tablets, it could indicate a heart attack, and emergency medical help should be sought. This education is crucial to ensure the client knows when to seek immediate medical attention.
Question 9 of 9
Reteplase (Retavase) has been ordered for a client diagnosed with an MI. The nurse understands that this drug needs to be administered within which time frame following the onset of symptoms?
Correct Answer: B
Rationale: Reteplase (Retavase) is a thrombolytic medication used in the treatment of myocardial infarction (MI). It is crucial to administer this drug within 30 minutes to 12 hours following the onset of symptoms to achieve optimal therapeutic effects and improve patient outcomes. Administering Reteplase within this time frame helps in restoring blood flow to the affected areas of the heart by dissolving blood clots, reducing myocardial damage, and potentially preventing further complications associated with MI.
