1. Which of the following is considered a class IA Sodium Channel blocker?

Correct answer: D

Rationale: Procainamide is a class IA antiarrhythmic drug that acts as a sodium channel blocker by blocking fast sodium channels. Mexiletine is a class IB antiarrhythmic drug, not class IA. Amiodarone is a class III antiarrhythmic, and Quinidine is a class IA antiarrhythmic but not a sodium channel blocker.

2. A client is receiving discharge instructions for a new prescription of Prednisone. Which of the following dietary instructions should be included?

Correct answer: A

Rationale: When a client is prescribed Prednisone, there is a risk of potassium depletion due to the medication. Therefore, it is essential to increase the intake of potassium-rich foods such as bananas, oranges, and spinach to help maintain adequate potassium levels in the body and prevent complications associated with low potassium levels. Choice B and D are incorrect as there is no specific need to increase dairy products or decrease protein intake with Prednisone. Choice C is also incorrect as avoiding foods high in vitamin K is more relevant for clients taking anticoagulants like warfarin.

3. A client has a new diagnosis of Fibromyalgia. Which of the following medications should the nurse anticipate being prescribed for this client?

Correct answer: D

Rationale: The correct answer is Duloxetine. Duloxetine is commonly used to treat fibromyalgia as a serotonin-norepinephrine reuptake inhibitor. It is also indicated for depression and diabetic peripheral neuropathy. Colchicine, Hydroxychloroquine, and Auranofin are not typically prescribed for fibromyalgia. Colchicine is primarily used to treat gout, Hydroxychloroquine for conditions like malaria and rheumatoid arthritis, and Auranofin for rheumatoid arthritis.

4. A drug ending in the suffix (tidine) is considered a ______.

Correct answer: D

Rationale: Drugs ending in -tidine are histamine (H2) receptor antagonists, which block the action of histamine at the H2 receptors, commonly used to reduce stomach acid production. Therefore, the correct answer is an 'H antagonist.' It is essential to be familiar with drug suffixes as they can provide clues to the drug's class and function.

5. A client is being taught about taking Tetracycline to treat a GI infection caused by Helicobacter pylori. Which of the following statements should indicate to the nurse that the client understands the instructions?

Correct answer: B

Rationale: The correct answer is B. Diarrhea can indicate the development of a suprainfection, which can be serious. Therefore, it is essential for the client to notify the healthcare provider if they experience diarrhea while taking Tetracycline to treat a GI infection caused by Helicobacter pylori. Choices A, C, and D are incorrect because taking Tetracycline with milk can reduce its absorption, discontinuing the medication prematurely can lead to treatment failure, and taking it just before bedtime may increase the risk of esophageal irritation due to the potential reflux of the medication.
