Nursing Elites

1. The nurse is administering sevelamer (RenaGel) during lunch to a client with end-stage renal disease (ESRD). The client asks the nurse to bring the medication later. The nurse should describe which action of RenaGel as an explanation for taking it with meals?

• A. Prevents indigestion associated with the ingestion of spicy foods.
• B. Binds with phosphorus in foods and prevents absorption.
• C. Promotes stomach emptying and prevents gastric reflux.
• D. Buffers hydrochloric acid and prevents gastric erosion.

Correct answer: B

Rationale: Sevelamer (RenaGel) binds with phosphorus in foods and prevents its absorption. By taking RenaGel with meals, the binding of phosphorus helps to reduce the phosphorus load absorbed from food, thus aiding in the management of hyperphosphatemia in clients with ESRD.

2. A client's healthcare provider has ordered a 'liver panel' in response to the client's development of jaundice. When reviewing the results of this laboratory testing, the nurse should expect to review what blood tests? Select one that doesn't apply.

• A. Alanine aminotransferase (ALT)
• B. C-reactive protein (CRP)
• C. Gamma-glutamyl transferase (GGT)
• D. Aspartate aminotransferase (AST)

Correct answer: B

Rationale: A 'liver panel' is a group of blood tests used to evaluate liver function. The components typically include ALT, GGT, and AST. While C-reactive protein (CRP) is a marker of inflammation and not part of a standard liver panel, it may be ordered for other diagnostic purposes.

3. An otherwise healthy 45-year-old man presents with severe hematochezia and moderate abdominal cramping since this morning. A barium enema one year ago was normal. On examination, his blood pressure is 120/78 and pulse is 100 while lying; when standing, the blood pressure is 110/76 and pulse is 136. His hematocrit is 34. What is the most likely cause of bleeding?

• A. Diverticular bleed
• B. Duodenal ulcer
• C. Inflammatory bowel disease
• D. Vascular ectasia (watermelon stomach)

Correct answer: B

Rationale: The patient's presentation with hematochezia, moderate abdominal cramping, and hemodynamic changes (increased pulse on standing) suggests an upper gastrointestinal bleed. The drop in blood pressure and rise in pulse rate when standing indicate orthostatic hypotension, which is a sign of significant blood loss. The absence of melena does not rule out an upper GI bleed. Ulcers in the duodenal bulb can erode into the gastroduodenal artery, leading to brisk blood loss. A normal barium enema one year ago makes diverticular bleeding less likely. Inflammatory bowel disease usually does not cause severe acute GI bleeding unless there is ulceration into a vessel. Vascular ectasia, like watermelon stomach, typically presents with chronic blood loss and iron deficiency anemia, more common in older women. The absence of vomiting and the presence of hematochezia make Mallory-Weiss tear less likely in this case.

4. A patient with chronic kidney disease (CKD) 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 primarily stimulates the bone marrow to produce more red blood cells, which helps to improve oxygen delivery to tissues. In chronic kidney disease, patients often develop anemia due to reduced erythropoietin production by the kidneys. By administering exogenous erythropoietin, the deficient hormone is replaced, leading to an increase in red blood cell production and subsequently improving the oxygen-carrying capacity of the blood.

5. While assessing a 70-year-old female client with Alzheimer's disease, the nurse notes deep inflamed cracks at the corners of her mouth. What intervention should the nurse include in this client's plan of care?

• A. Apply a moisturizing cream to the affected areas.
• B. Encourage the client to consume foods rich in vitamin B.
• C. Notify the healthcare provider for further evaluation.
• D. Ensure that the client gets adequate B vitamins in foods or supplements.

Correct answer: D

Rationale: Cracks at the corners of the mouth, known as angular cheilitis, can be a sign of vitamin B deficiency, specifically B2 (riboflavin) or B3 (niacin). The nurse should ensure that the client receives adequate B vitamins through foods rich in these nutrients or supplements to address the deficiency, which can help improve the condition of the client's mouth.
