Why should the nitrate patch be off for 8 hours per day?
- A. "There is no reason to take the patch off each day."
- B. "The patch can be addictive; leaving it off reduces the addiction."
- C. "You should only leave the patch off for 15 minutes."
- D. "Leaving the patch off for 8 hours per day helps to delay the development of tolerance."
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.
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.
Following a stroke, a client has been started on clopidogrel (Plavix). Why is this medication being administered?
- A. To prevent stroke in high-risk patients, such as those with prosthetic heart valves
- B. To decrease blood pressure
- C. To increase heart rate
- D. To provide antiplatelet activity in patients who cannot tolerate aspirin
Correct Answer: D
Rationale: Clopidogrel (Plavix) is an antiplatelet medication that inhibits platelet aggregation, reducing the risk of blood clots. It is commonly used in patients who have had a stroke and cannot tolerate aspirin due to allergies or intolerances. Choosing clopidogrel in these cases helps prevent further clot formation and reduces the risk of recurrent strokes.

The client with angina is being discharged to home. The nurse is instructing the client on dietary changes. What should be included in this teaching?

These dietary changes can help manage angina by reducing the workload on the heart and preventing further plaque buildup in the arteries. Choices B, C, and D are incorrect as dietary restrictions for angina typically involve reducing salt, fat, and alcohol intake, rather than increasing sugar or cholesterol intake.
