Nursing Elites

1. Prior to a dipyridamole thallium scan, what substance should the LPN/LVN ensure the client has not consumed?

• A. Caffeine
• B. Fatty meal
• C. Excess sugar
• D. Milk products

Correct answer: A

Rationale: Caffeine should be avoided before a dipyridamole thallium scan as it can interfere with the test results. Caffeine is a stimulant that can affect the heart rate and may lead to inaccurate findings during the scan. Fatty meals, excess sugar, and milk products do not specifically interfere with the dipyridamole thallium scan procedure. Therefore, it is essential for the LPN/LVN to check and ensure that the client has not consumed caffeine prior to the procedure to obtain accurate diagnostic results.

2. A client has a new prescription for alendronate. Which of the following instructions should the nurse include?

• A. Take the medication with a full glass of water.
• B. Lie down for 30 minutes after taking the medication.
• C. Take the medication at bedtime.
• D. Avoid dairy products while taking the medication.

Correct answer: A

Rationale: When taking alendronate, it is important to take the medication with a full glass of water to prevent esophageal irritation. This helps ensure that the medication reaches the stomach and is properly absorbed. Lying down after taking alendronate can increase the risk of esophageal irritation, which is why it is recommended to stay upright for at least 30 minutes after taking the medication. Taking the medication at bedtime or avoiding dairy products are not specific instructions associated with alendronate administration. Therefore, the correct instruction to include is to take the medication with a full glass of water.

3. A client with heart failure is being discharged with a prescription for digoxin (Lanoxin). The nurse should include which instruction in the discharge teaching?

• A. Take your pulse before each dose and hold the medication if your pulse is below 60 beats per minute
• B. Increase your fluid intake to at least 3 liters per day
• C. Report any weight loss of more than 2 pounds in a week
• D. Take the medication with meals to avoid gastrointestinal upset

Correct answer: A

Rationale: The correct instruction for a client taking digoxin is to monitor the pulse before each dose and hold the medication if the pulse is below 60 beats per minute. Digoxin can cause bradycardia, so it is crucial to assess the pulse rate before administration to prevent potential complications. Choices B, C, and D are incorrect because increasing fluid intake, reporting weight loss, or taking the medication with meals are not specific instructions related to the safe use of digoxin.

4. A client's serum calcium level is 7.9 mg/dL. The nurse is immediately concerned, knowing that this level could lead to which complication?

• A. Stroke
• B. Cardiac arrest
• C. High blood pressure
• D. Urinary stone formation

Correct answer: B

Rationale: A serum calcium level below normal (hypocalcemia) can lead to cardiac arrhythmias and potentially cardiac arrest. Calcium plays a crucial role in cardiac muscle contractility, and low levels can disrupt normal heart function, potentially leading to fatal arrhythmias and cardiac arrest. Choices A, C, and D are incorrect as hypocalcemia is not directly associated with stroke, high blood pressure, or urinary stone formation. The immediate concern with low serum calcium levels is the risk of cardiac complications.

5. The client is receiving furosemide (Lasix) for heart failure. What potential side effect should the nurse monitor for?

• A. Hypokalemia
• B. Hyperkalemia
• C. Hypernatremia
• D. Hypoglycemia

Correct answer: A

Rationale: The correct answer is A: Hypokalemia. Furosemide, a loop diuretic, causes potassium loss, leading to hypokalemia. Monitoring potassium levels is crucial because hypokalemia can result in cardiac arrhythmias and muscle weakness. Choices B, C, and D are incorrect because furosemide does not typically cause hyperkalemia, hypernatremia, or hypoglycemia.
