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. Which of the following is not a side effect of Sympathoplegics (Clonidine)?

• A. Hypertension
• B. Difficulty breathing
• C. Dry oral cavity
• D. Lethargic behavior

Correct answer: A

Rationale: The correct answer is A. Clonidine, a Sympathoplegic, typically causes hypotension rather than hypertension. The other side effects associated with Clonidine include dry oral cavity, lethargic behavior, and difficulty breathing, making them incorrect choices in this context.

3. A client with asthma has a new prescription for inhaled beclomethasone. Which of the following instructions should the nurse provide?

• A. Check the pulse after using the inhaler.
• B. Take the medication with food.
• C. Rinse the mouth after using the inhaler.
• D. Reduce caffeine consumption.

Correct answer: C

Rationale: The correct answer is C: 'Rinse the mouth after using the inhaler.' Rinsing the mouth after using inhaled beclomethasone is crucial to prevent fungal overgrowth in the mouth, a common side effect of corticosteroid inhalers. Checking the pulse after using the inhaler (Choice A) is not directly related to the use of beclomethasone. Taking the medication with food (Choice B) is not a specific instruction for inhaled beclomethasone. While reducing caffeine consumption (Choice D) can be beneficial for some health conditions, it is not a specific instruction related to using inhaled beclomethasone.

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

• A. Apply the patch to a different site each day.
• B. Remove the patch at bedtime each day.
• C. Apply the patch over an area with little or no hair.
• D. Keep the patch on for 24 hours at a time.

Correct answer: B

Rationale: The correct instruction for a Nitroglycerin transdermal patch is to remove it each day, usually at bedtime, to prevent tolerance. Keeping the patch on for 24 hours at a time can lead to tolerance development. Applying the patch to a different site each day is not necessary, as long as the area is rotated to prevent skin irritation. Applying the patch over an area with little or no hair is not a critical instruction for the Nitroglycerin patch.

5. A healthcare provider is reviewing the medical history of a client who is scheduled for surgery and takes Warfarin daily. Which of the following laboratory results should the healthcare provider monitor?

• A. Potassium level
• B. INR
• C. BUN
• D. Platelet count

Correct answer: B

Rationale: The INR (International Normalized Ratio) is the most important lab value to monitor in a client taking warfarin. Warfarin is an anticoagulant, and the INR reflects the effectiveness of anticoagulation therapy. Monitoring the INR helps ensure the client is within the therapeutic range to prevent both clotting and bleeding complications.
