Nursing Elites

1. The nurse is caring for a client with a diagnosis of myocardial infarction (MI) and is assisting the client in completing the diet menu. Which beverage does the nurse instruct the client to select from the menu?

• A. Tea
• B. Cola
• C. Coffee
• D. Lemonade

Correct answer: D

Rationale: Lemonade is the correct choice as it is caffeine-free, unlike tea, cola, and coffee, which contain caffeine that can potentially affect the client's heart rhythm. Caffeine can increase heart rate and blood pressure, which may not be advisable for a client with a recent MI. Tea, cola, and coffee should be avoided due to their caffeine content, which can have stimulant effects on the heart and may not be beneficial for a client recovering from a myocardial infarction.

2. A client with a history of angina pectoris complains of substernal chest pain. The nurse checks the client's blood pressure and administers nitroglycerin 0.4 mg sublingually. Five minutes later, the client is still experiencing chest pain. If the blood pressure is still stable, what should the nurse do next?

• A. Administer another nitroglycerin tablet.
• B. Apply 1 to 3 L/minute of oxygen via nasal cannula.
• C. Call for a 12-lead electrocardiogram (ECG) to be performed.
• D. Wait an additional 5 minutes, then give a second nitroglycerin tablet.

Correct answer: A

Rationale: When a client with angina pectoris continues to experience chest pain despite initial nitroglycerin administration and stable blood pressure, the appropriate next step is to administer another nitroglycerin tablet. This helps to further dilate coronary arteries, improving blood flow to the heart muscle and relieving chest pain. Applying oxygen via nasal cannula (Choice B) may be necessary if the client displays signs of respiratory distress or hypoxemia, but in this case, the priority is addressing the unresolved chest pain. Calling for a 12-lead electrocardiogram (ECG) (Choice C) is important to assess for any changes in the client's cardiac status, but administering another nitroglycerin tablet takes precedence in managing the ongoing chest pain. Waiting an additional 5 minutes before giving a second nitroglycerin tablet (Choice D) may delay symptom relief and potentially worsen the client's condition if the chest pain persists.

3. The LPN/LVN is assisting in the care of a client with chronic heart failure who is receiving digoxin (Lanoxin). Which sign should the nurse monitor for that could indicate digoxin toxicity?

• A. Bradycardia
• B. Tachycardia
• C. Hypertension
• D. Hyperglycemia

Correct answer: A

Rationale: Bradycardia is a common sign of digoxin toxicity and should be closely monitored. Digoxin toxicity can lead to various cardiac dysrhythmias, with bradycardia being a significant indicator. Monitoring the client's heart rate is crucial to detect and manage digoxin toxicity promptly. Tachycardia, hypertension, and hyperglycemia are not typically associated with digoxin toxicity. Tachycardia is more commonly seen with inadequate treatment of heart failure, hypertension is a possible but less common effect, and hyperglycemia is not a typical sign of digoxin toxicity.

4. The client with a history of heart failure is receiving digoxin (Lanoxin). Which electrolyte imbalance increases the risk of digoxin toxicity?

• A. Hypernatremia
• B. Hypercalcemia
• C. Hypokalemia
• D. Hypomagnesemia

Correct answer: C

Rationale: Hypokalemia increases the risk of digoxin toxicity as low potassium levels enhance the effects of digoxin on the heart, leading to toxicity and potential adverse effects. Hypernatremia (Choice A) is not directly associated with an increased risk of digoxin toxicity. Hypercalcemia (Choice B) does not increase the risk of digoxin toxicity. Hypomagnesemia (Choice D) can contribute to digoxin toxicity, but hypokalemia has a more significant impact on increasing the risk.

5. The client has been prescribed atorvastatin (Lipitor) for hyperlipidemia. Which instruction should the nurse provide to the client?

• A. Take the medication in the morning with breakfast.
• B. Avoid drinking grapefruit juice while taking this medication.
• C. Increase your intake of dietary fiber while on this medication.
• D. Avoid eating foods high in potassium.

Correct answer: B

Rationale: The correct instruction for the nurse to provide to the client prescribed atorvastatin (Lipitor) for hyperlipidemia is to avoid drinking grapefruit juice while taking this medication. Grapefruit juice can interfere with the metabolism of atorvastatin, leading to an increased risk of side effects. It is crucial for the client to adhere to this instruction to ensure the effectiveness and safety of the treatment. Choices A, C, and D are incorrect because taking the medication with breakfast, increasing dietary fiber intake, and avoiding foods high in potassium are not specific instructions related to atorvastatin therapy for hyperlipidemia.
