1. Why should the nitrate patch be off for 8 hours per day?
- A. “There is no reason to take the patch off each day.â€
- B. “The patch can be addictive; leaving it off reduces the addiction.â€
- C. “You should only leave the patch off for 15 minutes.â€
- D. “Leaving the patch off for 8 hours per day helps to delay the development of tolerance.â€
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.
2. 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?
- A. “A beta blocker.â€
- B. “A sodium channel blocker.â€
- C. “An alpha blocker.â€
- D. “A calcium channel blocker.â€
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.
3. When a client is discharged with nitroglycerin (Nitrostat), what should the nurse include in client education?
- A. “Your chest pain should go away with one tablet.â€
- B. “If your chest pain doesn’t go away after three tablets, call 911; you might be having a heart attack.â€
- C. “If your chest pain doesn’t go away with one tablet, you can repeat the dose as many times as you need to.â€
- D. “Be sure to call 911 before you take any tablets.â€
Correct answer: B
Rationale: The correct answer instructs the client on the appropriate use of nitroglycerin. Nitroglycerin is used to relieve chest pain or angina. If the chest pain does not subside after taking one tablet, the client should take a maximum of three tablets at 5-minute intervals. If the pain persists after three tablets, it could indicate a heart attack, and emergency medical help should be sought. This education is crucial to ensure the client knows when to seek immediate medical attention.
4. Reteplase (Retavase) has been ordered for a client diagnosed with an MI. The nurse understands that this drug needs to be administered within which time frame following the onset of symptoms?
- A. 45 minutes to 18 hours
- B. 30 minutes to 12 hours
- C. 90 minutes to 36 hours
- D. 60 minutes to 24 hours
Correct answer: B
Rationale: Reteplase (Retavase) is a thrombolytic medication used in the treatment of myocardial infarction (MI). It is crucial to administer this drug within 30 minutes to 12 hours following the onset of symptoms to achieve optimal therapeutic effects and improve patient outcomes. Administering Reteplase within this time frame helps in restoring blood flow to the affected areas of the heart by dissolving blood clots, reducing myocardial damage, and potentially preventing further complications associated with MI.
5. What is the first type of medication prescribed to prevent angina pain for a client?
- A. Beta blockers
- B. Alpha blockers
- C. Calcium channel blockers
- D. Organic nitrates
Correct answer: A
Rationale: Beta blockers are the first-line medication prescribed to prevent angina pain. They work by reducing the heart rate and blood pressure, decreasing the heart's demand for oxygen. This helps in preventing angina attacks by improving blood flow to the heart. Alpha blockers, calcium channel blockers, and organic nitrates are also used in angina treatment but are typically considered after beta blockers.
