1. What is the primary action of warfarin as an anticoagulant?

• A. Prevents the formation of blood clots
• B. Dissolves existing blood clots
• C. Dilates coronary arteries
• D. Treats rhythm disturbances

Correct answer: A

Rationale: The correct answer is A: "Prevents the formation of blood clots." Warfarin acts as an anticoagulant by inhibiting the synthesis of certain clotting factors in the liver. This action reduces the blood's ability to clot, making it effective in preventing the formation of blood clots. Choice B is incorrect because warfarin does not dissolve existing blood clots; it prevents their formation. Choice C is incorrect because warfarin's primary action is not to dilate coronary arteries. Choice D is incorrect as warfarin is not used to treat rhythm disturbances, but rather to prevent clot formation.

2. A client with chronic kidney disease has a new prescription for epoetin alfa. The nurse should instruct the client to increase dietary intake of which of the following substances?

• A. Iron
• B. Protein
• C. Potassium
• D. Sodium

Correct answer: A

Rationale: Patients with chronic kidney disease are often prescribed epoetin alfa to treat anemia. Epoetin alfa stimulates red blood cell production, increasing the body's demand for iron to support this process. Therefore, clients taking epoetin alfa should be advised to increase their dietary intake of iron-rich foods to meet the increased demand and prevent iron deficiency anemia. Choices B, C, and D are incorrect because while protein is essential for overall health, potassium and sodium intake may need to be restricted in clients with chronic kidney disease to manage electrolyte balance and blood pressure.

3. A client is taking Digoxin and has a new prescription for Colesevelam. Which of the following instructions should the nurse include in the teaching?

• A. Take digoxin with your morning dose of colesevelam.
• B. Your sodium and potassium levels will be monitored periodically while taking colesevelam.
• C. Watch for bleeding or bruising while taking colesevelam.
• D. Take colesevelam with food and at least one glass of water.

Correct answer: D

Rationale: When taking colesevelam, it should be administered with food and at least 8 oz of water to ensure proper absorption and reduce the risk of gastrointestinal side effects. Taking colesevelam with food also helps in binding to bile acids efficiently. Options A, B, and C are incorrect because they do not provide the necessary instruction for taking colesevelam correctly or monitoring specific side effects associated with this medication.

4. What is the first type of medication prescribed to prevent angina pain for a client?

• A. Beta blockers
• B. Alpha blockers
• C. Calcium channel blockers
• D. Organic nitrates

Correct answer: A

Rationale: Beta blockers are the first-line medication prescribed to prevent angina pain. They work by reducing the heart rate and blood pressure, decreasing the heart's demand for oxygen. This helps in preventing angina attacks by improving blood flow to the heart. Alpha blockers, calcium channel blockers, and organic nitrates are also used in angina treatment but are typically considered after beta blockers.

5. A client is receiving moderate sedation with Diazepam IV and is oversedated. Which of the following medications should the nurse anticipate administering to this client?

• A. Ketamine
• B. Naltrexone
• C. Flumazenil
• D. Fluvoxamine

Correct answer: C

Rationale: Flumazenil is a competitive benzodiazepine antagonist that can reverse the sedative effects of benzodiazepines like Diazepam. In cases of oversedation, administering Flumazenil can help counteract the excessive sedation and other effects of Diazepam, thereby promoting the client's recovery and preventing potential complications. Ketamine (Choice A) is a dissociative anesthetic and not used to reverse benzodiazepine sedation. Naltrexone (Choice B) is an opioid receptor antagonist, not indicated for benzodiazepine oversedation. Fluvoxamine (Choice D) is an antidepressant and not used to reverse the sedative effects of benzodiazepines.
