A patient who has been scheduled for an exercise stress electrocardiogram asks why this test is needed. Which of the following is the nurse's best response?
It determines a target heart rate.
It identifies how much more exercise is needed.
It shows how the heart performs during exercise.
It can predict whether a heart attack may occur.
The Correct Answer is C
Choice A reason: Determining a target heart rate is not the primary purpose of an exercise stress electrocardiogram; it is more about observing the heart's function under stress³.
Choice B reason: Identifying the need for more exercise is not the direct outcome of this test; it is used to assess cardiovascular response to stress³.
Choice C reason: The test is designed to show how the heart performs during exercise, which can help diagnose conditions like coronary artery disease³.
Choice D reason: Predicting a heart attack is not the purpose of an exercise stress electrocardiogram; rather, it helps to identify heart conditions that may lead to complications if left untreated³.

Correct Answer is C
Explanation
Choice A reason: Gluten is not typically restricted for patients taking MAOIs unless they have a separate condition that requires this diet.
Choice B reason: Extra salt does not interact with MAOIs, so it is not necessary to avoid it unless the patient has other health concerns that require a low-sodium diet.
Choice C reason: Processed lunch meats are high in tyramine, which can cause dangerous interactions with MAOIs, leading to hypertensive crises.
Choice D reason: While caffeine may need to be limited, it is not as critical as avoiding high-tyramine foods like processed lunch meats when taking MAOIs.
Correct Answer is C
Explanation
Choice A reason: While attaching leads for a 12-lead ECG is important, it is not the most immediate action required for a client showing signs of distress and potential hypoxia.
Choice B reason: Obtaining a blood sample is necessary for diagnosing the cause of chest pain but is not the first priority in an emergency situation.
Choice C reason: Initiating oxygen therapy is the first and most critical step in managing a client with severe chest pain, shortness of breath, and cyanosis to ensure adequate oxygenation.
Choice D reason: Inserting an IV catheter is important for administering medications and fluids but comes after ensuring the client is receiving sufficient oxygen.
