Nursing Elites

1. A healthcare provider is providing teaching to a client who has a new prescription for metronidazole. The healthcare provider should instruct the client to avoid which of the following?

• A. Dairy products
• B. Alcohol
• C. Leafy green vegetables
• D. Grapefruit juice

Correct answer: B

Rationale: The correct answer is B: Alcohol. Clients should avoid alcohol while taking metronidazole due to the risk of a disulfiram-like reaction. This reaction can cause symptoms like flushing, headache, nausea, and vomiting when alcohol is consumed while on metronidazole. Dairy products, leafy green vegetables, and grapefruit juice do not have significant interactions with metronidazole. Dairy products do not interfere with metronidazole absorption; leafy green vegetables are safe to consume as they do not affect metronidazole metabolism, and grapefruit juice is not contraindicated with metronidazole.

2. Which of the following is the antidote for lead poisoning?

• A. Naloxone
• B. Nitrite
• C. CaEDTA
• D. Dialysis

Correct answer: C

Rationale: Calcium disodium ethylenediaminetetraacetic acid (CaEDTA) is the antidote for lead poisoning. CaEDTA works by chelating lead, forming a complex that is then excreted in the urine. It is used in chelation therapy to treat lead poisoning by reducing lead levels in the body.

3. Potassium-sparing diuretics primarily affect which part of the kidney?

• A. Proximal convoluted tubule
• B. Loop of Henle
• C. Collecting duct
• D. Distal convoluted tubule

Correct answer: D

Rationale: Potassium-sparing diuretics exert their primary effects on the distal convoluted tubule in the kidney. By acting on this specific part of the nephron, these diuretics promote sodium excretion while sparing potassium, thus helping to maintain potassium levels in the body. This mechanism differs from other diuretics that may cause potassium loss as a side effect. Understanding the site of action of potassium-sparing diuretics is crucial in clinical practice for managing conditions like hypertension and edema where diuresis is necessary without the risk of hypokalemia.

4. When 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, a beta-blocker, can lead to bradycardia as an adverse effect due to its mechanism of action. The nurse should advise the client to monitor their pulse regularly, as a significant decrease may indicate bradycardia, a condition characterized by a slow heart rate.

5. When teaching a client with a new prescription for Amiodarone, which instruction should the nurse include?

• A. Take this medication with meals.
• B. Avoid drinking grapefruit juice.
• C. Take this medication at bedtime.
• D. Increase your intake of sodium-rich foods.

Correct answer: B

Rationale: The correct instruction is to avoid drinking grapefruit juice when taking Amiodarone. Grapefruit juice can inhibit the metabolism of Amiodarone, leading to increased blood levels of the drug and potentially causing adverse effects like cardiac toxicity. Choices A, C, and D are incorrect because taking Amiodarone with meals, at bedtime, or increasing sodium-rich foods intake are not relevant instructions for this medication.
