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 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.

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

• A. Avoid foods high in potassium while taking this medication.
• B. This medication may cause your blood pressure to increase.
• C. This medication can cause you to retain fluids.
• D. Take this medication with meals.

Correct answer: D

Rationale: The correct instruction for a client taking furosemide is to take the medication with meals. This helps prevent gastrointestinal upset and improves medication tolerance. Option A is incorrect because furosemide is a loop diuretic that can cause potassium depletion, so avoiding foods high in potassium is not necessary. Option B is incorrect as furosemide typically lowers blood pressure. Option C is incorrect because furosemide is a diuretic that promotes fluid loss rather than retention.

4. A nurse is caring for a client who is receiving warfarin therapy. Which of the following laboratory results indicates the need for an increase in the dose of warfarin?

• A. PT 28 seconds
• B. INR 1.2
• C. aPTT 40 seconds
• D. Fibrinogen 350 mg/dL

Correct answer: B

Rationale: An INR of 1.2 is below the therapeutic range for a client on warfarin, indicating inadequate anticoagulation. Therefore, the client would require an increase in the dose of warfarin to achieve the desired therapeutic effect. Choices A, C, and D are not indicative of the need for a dose increase in warfarin therapy. PT of 28 seconds is within the therapeutic range, aPTT of 40 seconds is also within the normal range, and fibrinogen level of 350 mg/dL does not provide information about the anticoagulant effect of warfarin.

5. A nurse is preparing to administer blood to a client. Which of the following actions should the nurse take first?

• A. Check the client's identification bracelet.
• B. Obtain the client's vital signs.
• C. Initiate the transfusion slowly over the first 15 minutes.
• D. Verify the client's blood type and Rh factor.

Correct answer: D

Rationale: The correct answer is to verify the client's blood type and Rh factor first before administering blood. This is crucial to ensure compatibility and prevent transfusion reactions. Checking the client's identification bracelet (Choice A) is important but should come after verifying blood type. Obtaining vital signs (Choice B) and initiating the transfusion slowly (Choice C) are important steps but verifying blood type is the priority to ensure safe blood administration.
