1. What is the primary advantage of prescribing rivaroxaban over warfarin for a patient with a history of deep vein thrombosis (DVT)?

• A. No need for regular INR monitoring
• B. Lower risk of bleeding
• C. Fewer dietary restrictions
• D. Longer half-life

Correct answer: A

Rationale: The primary advantage of prescribing rivaroxaban over warfarin for a patient with a history of deep vein thrombosis (DVT) is that rivaroxaban does not require regular INR monitoring. This eliminates the need for frequent blood tests to adjust the dosage, making it more convenient for patients to manage their anticoagulant therapy.

2. A client with Addison's disease is being treated with fludrocortisone (Florinef). Which electrolyte imbalance should the nurse monitor for?

• A. Hyperkalemia.
• B. Hyponatremia.
• C. Hypernatremia.
• D. Hypocalcemia.

Correct answer: C

Rationale: Fludrocortisone, such as Florinef, is a mineralocorticoid that promotes sodium retention and potassium excretion, which can lead to hypernatremia. Therefore, the nurse should closely monitor for hypernatremia when a client with Addison's disease is being treated with fludrocortisone. Hyperkalemia (Choice A) is incorrect because fludrocortisone promotes potassium excretion, leading to hypokalemia rather than hyperkalemia. Hyponatremia (Choice B) is incorrect as fludrocortisone promotes sodium retention. Hypocalcemia (Choice D) is unrelated to the action of fludrocortisone.

3. A 35-year-old woman presents with abdominal pain, diarrhea, and weight loss. She has a history of recurrent mouth ulcers and a perianal fistula. What is the most likely diagnosis?

• A. Ulcerative colitis
• B. Irritable bowel syndrome
• C. Crohn's disease
• D. Diverticulitis

Correct answer: C

Rationale: The combination of symptoms including recurrent mouth ulcers, perianal fistula, abdominal pain, diarrhea, and weight loss strongly suggests Crohn's disease. These extra-intestinal manifestations are characteristic of Crohn's disease, a chronic inflammatory condition that can affect any part of the gastrointestinal tract. Ulcerative colitis primarily involves the colon, while irritable bowel syndrome is a functional disorder without the inflammatory component seen in Crohn's disease. Diverticulitis typically presents with localized left lower quadrant pain and is less likely to cause mouth ulcers and perianal fistulas.

4. Which regimen is most effective for treating H. pylori infection?

• A. Metronidazole, bismuth subsalicylate, amoxicillin for 14 days
• B. Clarithromycin and omeprazole for 14 days
• C. Metronidazole, lansoprazole, and clarithromycin for 14 days
• D. Metronidazole, clarithromycin, and omeprazole for 7 days

Correct answer: C

Rationale: Regimen C, which consists of metronidazole, lansoprazole, and clarithromycin for 14 days, is recommended by the FDA as an effective treatment for H. pylori infection. This regimen has been shown to have a high eradication rate and is a standard recommendation in clinical practice guidelines for the management of H. pylori-related conditions.

5. A client with a history of myocardial infarction (MI) is prescribed atorvastatin (Lipitor). Which outcome indicates that the medication is effective?

• A. Increased blood pressure.
• B. Lowered cholesterol levels.
• C. Decreased heart rate.
• D. Improved liver function.

Correct answer: B

Rationale: The correct answer is B: Lowered cholesterol levels. Atorvastatin is a medication commonly prescribed to lower cholesterol levels, which is crucial in reducing the risk of further cardiovascular events, including myocardial infarction (MI). Monitoring cholesterol levels is essential to assess the effectiveness of atorvastatin therapy and its role in preventing future cardiac complications. Choices A, C, and D are incorrect because increased blood pressure, decreased heart rate, and improved liver function are not direct indicators of atorvastatin's effectiveness in a client with a history of MI.
