ATI Pharmacology Practice Exam A Questions
Question 1 of 4
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 2 of 4
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 3 of 4
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 4 of 4
A client asks the nurse to explain the difference between stable and unstable angina. What is the best response by the nurse?
Correct Answer: A
Rationale: Stable angina is typically triggered by physical exertion or emotional stress and is predictable in its frequency, intensity, and duration. In contrast, unstable angina is characterized by angina episodes that are unexpected, more severe, prolonged, and can occur at rest. Understanding these differences can help healthcare providers assess and manage angina episodes effectively, ensuring appropriate interventions are implemented promptly based on the type of angina present.
