Nursing Elites

1. How can the nurse best explain the difference between angina and a myocardial infarction to a client presenting with severe chest pain?

• A. “Angina usually resolves with rest, and is rarely fatal, while a myocardial infarction necessitates immediate treatment and can be life-threatening.”
• B. “There is a clear distinction between the two. You will receive treatment based on the diagnosis of a myocardial infarction.”
• C. “Both conditions result from a clot obstructing the coronary arteries. Angina occurs with the blockage of a small vessel, whereas a myocardial infarction occurs with a blockage of a large vessel.”
• D. “Angina may not cause as intense chest pain, whereas a myocardial infarction always presents 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.

2. A client with tobacco use disorder is being educated about Nicotine replacement therapy. Which statement by the client indicates an understanding of the teaching?

• A. I should avoid eating right before chewing a piece of nicotine gum.
• B. I will need to stop using the nicotine gum after 1 year.
• C. I know that nicotine gum is a safe alternative to smoking during pregnancy.
• D. I must chew the nicotine gum quickly for about 15 minutes.

Correct answer: A

Rationale: The correct answer is A. To maximize the effectiveness of nicotine gum, the client should avoid eating or drinking 15 minutes before and while using it. This helps ensure proper absorption of nicotine through the oral mucosa. Choice B is incorrect because the duration of nicotine gum use can vary depending on the individual's needs and progress. Choice C is incorrect as nicotine gum should be used during pregnancy only under healthcare provider guidance. Choice D is incorrect because nicotine gum should be chewed slowly until a tingling sensation is felt, then parked between the cheek and gum until the tingling stops.

3. A client is starting a new prescription for verapamil. Which of the following instructions should be included?

• A. Take the medication with a full glass of water.
• B. Avoid grapefruit juice.
• C. Monitor blood pressure regularly.
• D. Monitor heart rate daily.

Correct answer: B

Rationale: Clients prescribed verapamil should be advised to avoid grapefruit juice as it can potentiate the drug's effects, leading to adverse reactions. Grapefruit juice can inhibit the metabolism of verapamil, resulting in higher blood levels of the medication and an increased risk of side effects. Instructions such as taking the medication with a full glass of water (Choice A) are not specific to verapamil and are generally recommended. While monitoring blood pressure regularly (Choice C) is important for clients on antihypertensive medications, it is not a direct concern related to verapamil. Monitoring heart rate daily (Choice D) is not a primary consideration when starting verapamil, as it is more commonly used for its effects on blood pressure and arrhythmias rather than heart rate.

4. 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?

• A. NSAIDs
• B. Cardiac glycosides
• C. Beta blockers
• D. None of the above

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.

5. How do ACE inhibitors work?

• A. Block the vasoconstrictor and aldosterone effects of angiotensin II at the receptor site
• B. Block stimulation of beta 1 and beta 2 at the receptor sites
• C. Block the conversion of angiotensin I to the vasoconstrictor angiotensin II
• D. None of the above

Correct answer: C

Rationale: ACE inhibitors work by inhibiting the conversion of angiotensin I to angiotensin II. Angiotensin II is a potent vasoconstrictor, and by blocking its production, ACE inhibitors help dilate blood vessels, reduce blood pressure, and decrease the workload of the heart. Choice A is incorrect because it describes the mechanism of action of angiotensin receptor blockers (ARBs), not ACE inhibitors. Choice B is incorrect as it describes beta-blockers, not ACE inhibitors. Choice D is incorrect as ACE inhibitors do have a specific mechanism of action.
