Nursing Elites

1. Which of the following is a sign of digoxin toxicity?

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

Correct answer: A

Rationale: The correct answer is A, Bradycardia. Bradycardia, or a slower than normal heart rate, is a classic sign of digoxin toxicity. Digoxin is a medication commonly used to treat heart conditions, but an excess of digoxin in the body can lead to toxicity. This toxicity can manifest as various symptoms, with bradycardia being one of the most common ones. Hypertension (high blood pressure) and tachycardia (fast heart rate) are not typical signs of digoxin toxicity. Tachypnea, which refers to rapid breathing, is also not a common sign of digoxin toxicity.

2. A client is being taught how to perform self-catheterization. Which of the following instructions should the nurse include?

• A. Clean the catheter with alcohol after each use.
• B. Perform self-catheterization while sitting on the toilet.
• C. Use a new catheter each time you perform self-catheterization.
• D. Lubricate the catheter tip with petroleum jelly before insertion.

Correct answer: C

Rationale: The correct answer is C: 'Use a new catheter each time you perform self-catheterization.' It is essential to use a new, sterile catheter each time to prevent infection during the procedure. Choice A is incorrect because cleaning the catheter with alcohol may not be sufficient to prevent infection. Choice B is incorrect because self-catheterization is typically done in a clean, private area, not necessarily on the toilet. Choice D is incorrect because lubricating the catheter tip with petroleum jelly is a common practice but not as crucial as using a new catheter each time to prevent infection.

3. A nurse is providing teaching to a client who has a new prescription for atorvastatin. Which of the following instructions should the nurse include?

• A. Avoid drinking grapefruit juice while taking this medication.
• B. Take this medication with food to prevent stomach upset.
• C. You should take this medication at bedtime.
• D. You should take this medication on an empty stomach.

Correct answer: A

Rationale: The correct answer is A: 'Avoid drinking grapefruit juice while taking this medication.' Grapefruit juice can increase the risk of toxicity when taken with atorvastatin. Choice B is incorrect because atorvastatin should be taken without regard to meals. Choice C is incorrect because atorvastatin can be taken at any time of the day. Choice D is incorrect because atorvastatin does not need to be taken on an empty stomach.

4. A nurse is providing teaching to a client who has a new prescription for warfarin. Which of the following statements indicates a need for further teaching?

• A. I will take warfarin every other day.
• B. I will eat more leafy green vegetables while taking warfarin.
• C. I will use a soft toothbrush while taking warfarin.
• D. I will have my INR checked regularly while taking warfarin.

Correct answer: B

Rationale: The correct answer is B. Eating more leafy green vegetables can increase vitamin K intake, which may reduce the effectiveness of warfarin. This can lead to fluctuations in the International Normalized Ratio (INR) levels, affecting the medication's efficacy. Choices A, C, and D are correct statements. Taking warfarin every other day, using a soft toothbrush to prevent gum bleeding, and having regular INR checks are all appropriate and important actions when taking warfarin.

5. Which lab value is most critical to monitor in a patient receiving insulin therapy?

• A. Monitor blood glucose
• B. Monitor potassium levels
• C. Monitor calcium levels
• D. Monitor sodium levels

Correct answer: A

Rationale: The correct answer is to monitor blood glucose levels. When a patient is receiving insulin therapy, it is crucial to monitor blood glucose levels regularly to prevent hypoglycemia, a potential side effect of insulin therapy. Monitoring potassium, calcium, or sodium levels is important for different medical conditions or treatments and is not directly related to insulin therapy.
