1. A client has a new prescription for a Nitroglycerin transdermal patch for Angina Pectoris. Which of the following instructions should the nurse include?
- A. Remove the patch each evening.
- B. Do not cut the patch in half even if angina attacks are under control.
- C. Take off the nitroglycerin patch if a headache occurs.
- D. Apply a new patch every 48 hours.
Correct answer: A
Rationale: The correct instruction is to remove the nitroglycerin patch each evening to prevent tolerance. This allows for a 10- to 12-hour nitrate-free period daily, reducing the risk of developing tolerance to nitroglycerin. Cutting the patch in half is not recommended because it can alter the dosing and absorption rate, leading to inadequate symptom control. Taking off the patch for a headache is not necessary as headaches are a common side effect that may improve with continued use. Applying a new patch every 48 hours is not correct as it may not provide continuous symptom relief for angina.
2. A healthcare professional is reviewing the medication list of a client who has a new prescription for Digoxin to treat heart failure. Which of the following medications places the client at risk for Digoxin toxicity?
- A. Spironolactone
- B. Calcium channel blockers
- C. Loop diuretics
- D. ACE inhibitors
Correct answer: C
Rationale: Loop diuretics, such as Furosemide, can increase the risk of Digoxin toxicity by causing hypokalemia. Hypokalemia enhances the toxic effects of Digoxin on the heart, leading to an increased risk of Digoxin toxicity. Spironolactone (Choice A) is less likely to cause hypokalemia and does not significantly increase the risk of Digoxin toxicity. Calcium channel blockers (Choice B) and ACE inhibitors (Choice D) do not directly increase the risk of Digoxin toxicity through hypokalemia; therefore, they are not the medications that place the client at risk for Digoxin toxicity.
3. A client has ordered a thrombolytic medication for the treatment of CVA. Which type of stroke should not be treated with a thrombolytic?
- A. Hemorrhagic stroke
- B. Thrombotic stroke
- C. Both types can be treated with a thrombolytic
- D. Neither type can be treated with a thrombolytic
Correct answer: A
Rationale: Thrombolytic medications are used to dissolve blood clots. In the case of a hemorrhagic stroke, where there is bleeding in the brain, the use of thrombolytics can worsen the condition by increasing bleeding. Therefore, hemorrhagic strokes should not be treated with thrombolytic medications.
4. When caring for a client prescribed Lithium, which laboratory value should the nurse monitor to assess for potential toxicity?
- A. Serum sodium
- B. Serum lithium
- C. Serum potassium
- D. Serum calcium
Correct answer: B
Rationale: The nurse should monitor the client's serum lithium levels to ensure they are within the therapeutic range and to assess for potential toxicity. Monitoring serum lithium levels is crucial because lithium has a narrow therapeutic range, and levels outside this range can lead to toxicity, which can be life-threatening. Therefore, regular monitoring is essential to prevent adverse effects and ensure the medication's effectiveness.
5. A healthcare provider is reviewing the medical history of a client who is scheduled for surgery and takes Warfarin daily. Which of the following laboratory results should the healthcare provider monitor?
- A. Potassium level
- B. INR
- C. BUN
- D. Platelet count
Correct answer: B
Rationale: The INR (International Normalized Ratio) is the most important lab value to monitor in a client taking warfarin. Warfarin is an anticoagulant, and the INR reflects the effectiveness of anticoagulation therapy. Monitoring the INR helps ensure the client is within the therapeutic range to prevent both clotting and bleeding complications.
