Nursing Elites

1. A client with chronic renal failure is scheduled to receive epoetin alfa (Epogen). Which laboratory result should the nurse review before administering the medication?

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

Correct answer: C

Rationale: The correct answer is to review the hemoglobin level before administering epoetin alfa (Epogen) to assess its effectiveness in stimulating red blood cell production. Hemoglobin level is a crucial indicator to monitor in clients with chronic renal failure receiving this medication. Choice A (Blood urea nitrogen) and Choice B (Creatinine clearance) are commonly monitored in renal failure but are not specifically relevant to assessing the effectiveness of epoetin alfa. Choice D (Serum potassium) is important to monitor due to potential imbalances in renal failure, but it is not directly related to evaluating the effectiveness of epoetin alfa.

2. What is the best therapy for a 65-year-old man with symptoms of regurgitation, chest pain, dysphagia, weight loss, dilated esophagus, and an absent gastric air bubble on CXR?

• A. Proton-pump inhibitor
• B. Endoscopic balloon dilatation
• C. Sucralfate
• D. Esophageal resection

Correct answer: B

Rationale: The patient's presentation and radiologic findings are consistent with achalasia. The absence of a mass on upper endoscopy and CT scan helps rule out secondary causes. Achalasia is best managed with endoscopic balloon dilatation or myotomy. Proton-pump inhibitors are not effective for achalasia. Sucralfate is not a primary treatment for achalasia. Esophageal resection is only considered if malignancy develops. Patients with achalasia may experience chest pain and weight loss due to food accumulation in the dilated esophagus. Endoscopic balloon dilatation is a safe and effective treatment option for improving symptoms in achalasia patients.

3. A 28-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 is characteristic of Crohn's disease. These extra-intestinal manifestations, along with the gastrointestinal symptoms, point towards Crohn's disease rather than ulcerative colitis, irritable bowel syndrome, or diverticulitis.

4. A patient with chronic kidney disease (CKD) is prescribed calcium acetate. What is the primary purpose of this medication?

• A. Treat hyperkalemia
• B. Reduce phosphate levels
• C. Lower blood pressure
• D. Increase hemoglobin levels

Correct answer: B

Rationale: The primary purpose of prescribing calcium acetate to a patient with chronic kidney disease (CKD) is to reduce phosphate levels. Calcium acetate binds to dietary phosphate, preventing its absorption and helping to manage hyperphosphatemia commonly seen in CKD patients.

5. A patient with severe anemia is prescribed erythropoietin. What is the primary action of this medication?

• A. Stimulate white blood cell production
• B. Increase platelet count
• C. Promote red blood cell production
• D. Enhance clotting factor production

Correct answer: C

Rationale: Erythropoietin is a hormone that primarily stimulates the bone marrow to produce more red blood cells. By increasing red blood cell production, erythropoietin helps to improve oxygen delivery to tissues, which is essential in managing anemia. Choices A, B, and D are incorrect because erythropoietin specifically targets red blood cell production and does not have a direct effect on white blood cells, platelets, or clotting factors.
