Nursing Elites

1. When taking Digoxin, low levels of what can cause toxicity?

• A. Potassium
• B. Calcium
• C. Sodium
• D. Magnesium

Correct answer: A

Rationale: Low potassium levels can lead to Digoxin toxicity. Digoxin competes with potassium for binding sites on the sodium-potassium pump. When potassium levels are low, there is an increased risk of Digoxin binding and toxicity. Choice B (Calcium) is incorrect because low calcium levels are not directly linked to Digoxin toxicity. Choice C (Sodium) is incorrect as low sodium levels do not cause Digoxin toxicity. Choice D (Magnesium) is incorrect as low magnesium levels do not contribute to Digoxin toxicity.

2. When should Montelukast be taken?

• A. At least two hours before exercise
• B. Daily in the evening
• C. Two hours before exercise or daily in the evening
• D. None of the above

Correct answer: B

Rationale: Montelukast should be taken daily in the evening to effectively manage asthma symptoms. Taking it at the same time each day helps maintain a consistent level of the medication in the body, providing optimal control over asthma symptoms and inflammation. Choice A is incorrect because Montelukast should not be taken specifically before exercise, but rather daily. Choice C is incorrect because although taking Montelukast two hours before exercise is not necessary, taking it daily in the evening is essential for its effectiveness. Choice D is incorrect as Montelukast should be taken daily to manage asthma.

3. A healthcare professional working in an emergency department is caring for a client who has Benzodiazepine toxicity due to an overdose. Which of the following actions is the healthcare professional's priority?

• A. Administer flumazenil.
• B. Identify the client's level of orientation.
• C. Infuse IV fluids.
• D. Prepare the client for gastric lavage.

Correct answer: B

Rationale: When managing a client with Benzodiazepine toxicity, the priority action for the healthcare professional is to assess the client. Identifying the client's level of orientation allows the healthcare professional to understand the client's cognitive status, which is crucial for further interventions and decision-making in the care plan. Administering flumazenil (Choice A) may precipitate withdrawal symptoms and should be done cautiously. Infusing IV fluids (Choice C) can be important but is not the priority over assessing the client. Gastric lavage (Choice D) is not typically recommended due to the risk of complications and its limited effectiveness in cases of Benzodiazepine overdose.

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

• A. Take this medication with food.
• B. Take this medication at bedtime.
• C. Take this medication on an empty stomach.
• D. Take this medication with antacids.

Correct answer: C

Rationale: Levothyroxine should be taken on an empty stomach to increase absorption and efficacy. Taking it with food or antacids can interfere with its absorption. By taking Levothyroxine on an empty stomach, the client ensures optimal absorption and effectiveness of the medication.

5. When caring for a client prescribed Digoxin, which of the following laboratory values should the nurse monitor to assess for potential toxicity?

• A. Sodium
• B. Potassium
• C. Magnesium
• D. Calcium

Correct answer: B

Rationale: When a client is prescribed Digoxin, monitoring potassium levels is crucial as hypokalemia can increase the risk of Digoxin toxicity. Low potassium levels can potentiate the effects of Digoxin on the heart, leading to toxicity. Therefore, regular monitoring of potassium levels helps in preventing adverse effects and ensuring the safe use of Digoxin. Sodium, magnesium, and calcium levels are not directly associated with Digoxin toxicity; hence, they are not the primary focus for monitoring in this case.
