1. What is the therapeutic use of Phenytoin?

• A. Replacement in hypothyroidism to restore normal hormonal balance
• B. Diminished accumulation of acid in the gastric lumen with lessened gastroesophageal reflux
• C. Diminished seizure activity, termination of ventricular arrhythmias
• D. Prevention of thrombus formation, prevention of extension of existing thrombi

Correct answer: C

Rationale: Phenytoin is primarily used to diminish seizure activity and is effective in terminating ventricular arrhythmias. It works by stabilizing neuronal membranes, reducing repetitive neuronal firing, and limiting the spread of seizure activity in the brain. While phenytoin does not have a direct role in preventing thrombus formation or extending existing thrombi, it is crucial in managing seizures and certain arrhythmias.

2. 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.

3. A client who has been taking prednisone to treat asthma is advised to discontinue the medication. The client should be instructed to reduce the dose gradually to prevent which of the following adverse effects?

• A. Hyperglycemia
• B. Adrenocortical insufficiency
• C. Severe dehydration
• D. Rebound pulmonary congestion

Correct answer: B

Rationale: Abruptly stopping prednisone can result in adrenocortical insufficiency due to suppression of the adrenal glands. Gradually tapering the dose helps the body adjust and resume its natural cortisol production, preventing adrenal insufficiency. Choice A, hyperglycemia, is a possible adverse effect of prednisone, but it is not the primary reason for gradual tapering. Severe dehydration (Choice C) and rebound pulmonary congestion (Choice D) are not typically associated with discontinuing prednisone.

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

• A. Bone pain
• B. Constipation
• C. Tinnitus
• D. Dry mouth

Correct answer: A

Rationale: When a client is starting therapy with filgrastim, monitoring for bone pain is essential. Filgrastim can lead to increased bone marrow activity, resulting in bone pain as a common adverse effect. Instructing the client to monitor and report any bone pain promptly can help in managing this side effect effectively.

5. A client is starting therapy with Metformin. Which of the following instructions should the nurse include?

• A. Take this medication with your first bite of food.
• B. Take this medication on an empty stomach.
• C. Take this medication before bedtime.
• D. Take this medication every other day.

Correct answer: A

Rationale: Metformin should be taken with meals to reduce gastrointestinal side effects and ensure better absorption. Instructing the client to take the medication with the first bite of food helps in achieving optimal effectiveness and minimizes the risk of side effects like nausea or upset stomach. Choice B is incorrect because taking Metformin on an empty stomach can lead to increased gastrointestinal side effects. Choice C is incorrect as there is no specific timing requirement for taking Metformin before bedtime. Choice D is incorrect as Metformin is usually taken daily, not every other day.
