Nursing Elites

1. What is the primary action of amlodipine when prescribed to a patient with hypertension?

• A. Increase heart rate
• B. Reduce blood pressure
• C. Lower cholesterol levels
• D. Decrease blood sugar levels

Correct answer: B

Rationale: Amlodipine is a calcium channel blocker that works by relaxing the blood vessels, leading to a reduction in blood pressure. This medication does not increase heart rate, lower cholesterol levels, or decrease blood sugar levels.

2. 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.

3. A client with chronic kidney disease is prescribed a low-protein diet. Which laboratory result should the nurse monitor to evaluate the effectiveness of the diet?

• A. Blood urea nitrogen (BUN)
• B. Serum potassium
• C. Serum calcium
• D. Creatinine clearance

Correct answer: A

Rationale: Blood urea nitrogen (BUN) levels should be monitored to assess the effectiveness of a low-protein diet in clients with chronic kidney disease. BUN levels reflect the breakdown of protein in the body, and a low-protein diet aims to reduce BUN levels to lessen the workload on the kidneys. Therefore, monitoring BUN levels is crucial in managing kidney function and evaluating the impact of dietary modifications. Serum potassium, serum calcium, and creatinine clearance are important parameters to monitor in clients with chronic kidney disease, but they are not specifically indicative of the effectiveness of a low-protein diet. Serum potassium levels are crucial in assessing electrolyte balance, serum calcium levels are important for bone health and nerve function, and creatinine clearance reflects kidney function overall, not just the impact of a low-protein diet.

4. A client with chronic kidney disease (CKD) is scheduled for hemodialysis. Which pre-dialysis assessment finding should the nurse report to the healthcare provider?

• A. Serum potassium of 5.5 mEq/L.
• B. Blood pressure of 180/90 mm Hg.
• C. Heart rate of 80 beats per minute.
• D. Serum sodium of 140 mEq/L.

Correct answer: B

Rationale: The correct answer is B. A blood pressure of 180/90 mm Hg is elevated and should be reported to the healthcare provider before hemodialysis. Hypertension can have a significant impact on the effectiveness and safety of the dialysis treatment. Controlling blood pressure before the procedure is crucial to prevent complications during the dialysis session.

5. A 65-year-old woman presents with difficulty swallowing, weight loss, and a history of long-standing heartburn. She has been on proton-pump inhibitors for years, but her symptoms have worsened. What is the most likely diagnosis?

• A. Peptic stricture
• B. Esophageal cancer
• C. Achalasia
• D. Esophageal spasm

Correct answer: B

Rationale: The presentation of difficulty swallowing, weight loss, and worsening symptoms despite long-term use of proton-pump inhibitors raises suspicion for esophageal cancer, especially in a patient with a history of chronic heartburn. Esophageal cancer should be considered in this scenario due to the concerning symptoms and lack of improvement despite appropriate medical management.
