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. A client is starting therapy with Atenolol. Which of the following adverse effects should the nurse instruct the client to monitor?

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

Correct answer: C

Rationale: Atenolol is a beta-blocker that can cause bradycardia as an adverse effect due to its mechanism of action in slowing down the heart rate. The nurse should instruct the client to monitor their pulse regularly and report any significant decreases to prevent complications related to bradycardia.

3. When teaching a client with a new prescription for Warfarin, which herbal supplement should the nurse instruct the client to avoid?

• A. St. John's wort
• B. Echinacea
• C. Garlic
• D. Ginseng

Correct answer: A

Rationale: The correct answer is St. John's wort. St. John's wort can reduce the effectiveness of Warfarin by interacting with its metabolism, potentially leading to decreased anticoagulant effects. Therefore, the nurse should instruct the client to avoid using St. John's wort while taking Warfarin to prevent adverse drug interactions. Echinacea, garlic, and ginseng are not the correct answers in this case. While these herbal supplements may also interact with Warfarin and affect its efficacy, St. John's wort has a well-known interaction with Warfarin that can significantly impact its anticoagulant effects. Educating the client about the specific interaction between St. John's wort and Warfarin is crucial to ensure patient safety and the medication's therapeutic benefit.

4. A client has a new prescription for Enalapril. Which of the following adverse effects should the nurse monitor?

• A. Dry cough
• B. Weight gain
• C. Diarrhea
• D. Nausea

Correct answer: A

Rationale: The correct answer is A: Dry cough. A persistent dry cough is a common adverse effect of Enalapril, an ACE inhibitor. Enalapril can cause the accumulation of bradykinin, leading to cough. Monitoring for a persistent dry cough is crucial as it may indicate the need for further evaluation and possible medication adjustment. Choices B, C, and D are not typically associated with Enalapril use and are less likely to be monitored as adverse effects.

5. What classification of drug is Penicillin?

• A. Antiarrhythmic
• B. Anticonvulsant
• C. Antibacterial
• D. Mood stabilizer

Correct answer: C

Rationale: Penicillin is classified as an antibacterial drug, specifically used to treat bacterial infections. It works by inhibiting the growth of bacteria, making it an effective treatment for various bacterial infections. Choices A, B, and D are incorrect as Penicillin does not belong to these drug classifications. Penicillin does not have any direct effect on heart rhythm (antiarrhythmic), does not treat seizures (anticonvulsant), and is not used to stabilize mood (mood stabilizer).
