Question 1 of 5

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 2 of 5

Which drug class has been found to decrease mortality if given within 8 hours of an MI due to a decrease in cardiac workload?

Correct Answer: B

Rationale: Beta-adrenergic blockers have been shown to decrease mortality when administered within 8 hours of a myocardial infarction (MI). They do so by reducing cardiac workload, which helps improve outcomes post-MI. These drugs work by blocking the effects of adrenaline on the heart, leading to decreased heart rate, blood pressure, and myocardial oxygen demand, thereby protecting the heart muscle from further damage. This makes them a crucial part of the treatment regimen for acute coronary syndromes like MI.

Question 3 of 5

A client has been prescribed a calcium channel blocker for angina. The nurse knows this medication should NOT be used with caution in combination with which drug classes?

Correct Answer: C

Rationale: Calcium channel blockers and beta blockers should be used with caution together because they can both suppress heart function, potentially leading to bradycardia, heart block, or heart failure. NSAIDs and cardiac glycosides do not have significant interactions with calcium channel blockers in the same way, so they are not typically a cause for concern when combined.

Question 4 of 5

The client asks the nurse about common side effects of calcium channel blockers. What should the nurse include in client teaching?

Correct Answer: A

Rationale: One of the common side effects of calcium channel blockers is a headache. This is important information for the nurse to include in client teaching as it helps the client understand potential adverse effects of the medication. Constipation, epistaxis, and dysuria are not typically associated with calcium channel blockers.

Question 5 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.
