ATI Pharmacology Practice Exam A Questions
Question 1 of 5
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 2 of 5
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 3 of 5
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 4 of 5
Which part of the body requires a continuous supply of oxygen and vital nutrients to support life and death?
Correct Answer: C
Rationale: The brain requires a continuous supply of oxygen and vital nutrients to support life and prevent death. Oxygen and nutrients are essential for brain function, and any interruption in the supply can lead to serious consequences, including brain damage or death.
Therefore, ensuring a constant flow of oxygen and nutrients to the brain is vital for survival and overall health.
Question 5 of 5
A client has been prescribed diltiazem (Cardizem) and asks the nurse what type of drug this is. Which response by the nurse is most appropriate?
Correct Answer: D
Rationale: Diltiazem (Cardizem) belongs to the class of drugs known as calcium channel blockers. These medications work by blocking calcium from entering the muscle cells of the heart and blood vessels, leading to relaxation of the blood vessels and reduced workload on the heart. This helps in lowering blood pressure and improving blood flow. It is crucial for the nurse to provide accurate information to the client about the type of drug prescribed to ensure understanding and compliance with the treatment plan.
